Abstract: There is a national trend for swine enterprises to increase in size due to cost efficiencies associated with economies of scale. This study was performed to evaluate the effect of farm size on manure application management for a survey o f 391 swine producers in Minnesota. There was a statistically significant effect of farm size on almost all of the variables evaluated. As farm size increased: a) more manure was handled in the liquid form; b) more farms analytically tested their manure; c) more farms calibrated their application equipment; d) less manure was applied in the s ummer and winter months; e) broadcast manure applications decreased while injected manure increased; and f) more farms kept records of manure applications. However, while the management practices associated with the larger farms were betted correlated to recommended practices, the ratio of animal units to the number of acres owned and available for manure application increased steeply as farm size categories went from small to large.

Abstract: Manure's impact on the environment is a concern for both livestock producers and the general public. A survey of Minnesota swine producers was conducted to determine current manure handling systems and manure management practices. A questionnaire containing 36 questions was mailed to 699 Minnesota swine producers. Questions focused on manure collection, storage, and application systems, dead pig disposal, and swine housing system. Survey responses indic ate: a) most producers market 2,000 pigs per year or fewer; b) most producers handle some manure as a solid; c) the majority of producers are not testing manure, calibrating manure application equipment, or keeping records of manure applications; d) surfa ce application of manure is more common than subsurface injection; e) rendering and burial are the most common means of dead pig disposal.

Abstract: Different sources and levels of amino acids (soybean meal at 0, 10, 20 or 40% of dry matter; similar quantities of lysine and methionine in synthetic forms) and sugars were mixed with broiler litter and placed in dacron bags embedded in a deep-stack for 3 or 9 weeks to determine changes in concentrations of nitrogen fractions and digestibility in ruminants. Pepsin-insoluble nitrogen concentration after 48 h of ruminal incubation was not changed by deep-stacking for 3 wk and only slightly elevated at 9 wk. Deep-stacking did not markedly alter in situ ruminal disappearance of broiler litter nitrogen. Conversely, in situ ruminal nitrogen disappearance of soybean meal substrates was decreased by deep-stacking; the change was greater for 16 t han for 48 h of ruminal incubation. Sugar addition to soybean meal substrates did not appear to enhance rumen undegradable protein concentration.

Abstract: This article reports a laboratory study of swine manure decomposition in a deep pit. Distributions of solids, organic matter, pH, and ammonia in fresh swine manure after 12 h settling in a 1.2 m column were characterized, and solids redu ction and ammonia generation rate during 28 d anaerobic decomposition were determined by using the manure initially having 1.8% and 3.3% total solids content (TS). In the settled manure, the pH became lower toward the bottom of the pit where manure solids and organic matter became concentrated, and the pH of bottom manure layer was 0.5 and 0.9 unit lower than the pH of top manure layer for the manure initially having 1.8% and 3.3% TS, respectively. Ammonia distribution in the manure was relatively uniform . The manure started to decompose rapidly after excretion from pigs. During the 28 d decomposition period, the solids contents of bottom manure layers were reduced linearly with time, and ammonia increased logrithmically with time. Higher temperature resulted in higher solids reduction and ammonia generation rate in the manure. The TS of bottom layer manure was reduced by 15% at 20 degrees C and 27% at 30 degrees C by the end of the 28 d period.

Abstract: A 2-yr study was conducted to evaluate 1) the effects of nitrogen level from swine lagoon effluent on forage composition and animal performance and 2) the effects of supplemental escape protein (EP) on performance by steers grazing pastu res fertilized with swine lagoon effluent. Bermudagrass (Cynodon dactylon) pastures were fertilized via sprinkler irrigation with either 448 or 896 kg/ha of N from swine lagoon effluent (two pasture replications/treatment). Within each pasture, four suppl ement treatments were evaluated using electronic Calan gates (8 steers.pasture-1.yr-1). The treatments were 1) negative control (pasture only); 2) energy control, which supplied 79.9 g of EP.hd-1.d-1; 3) 159 g of EP.hd-1.d-1, and 4) 239 g of EP.hd-1.d-1. Gains were increased (P < .05) an average of .15 kg/d by supplementation, with no differences in gain among supplements. Forage samples representative of that grazed by steers (CONSUM) and representative of all available forage (AVAIL) were obtained at 14-d intervals.

Abstract: In many areas with confined animal operations, continual manure application has increased soil P above amounts sufficient for optimum crop yields. In these areas, it is of economic and environmental importance to determine how long high- P soils will remain above crop sufficiency and identify soils where P contents would decrease most rapidly under similar management conditions. Thus, the surface 5 cm of 23 high-P soils (85-419 mg kg-1 Mehlich-3 P) in Oklahoma and Texas, which had receive d beef feedlot, poultry, or swine manure (90-1880 kg P ha-1 yr-1 for up to 35 yr) were successively extracted with Fe-oxide-impregnated paper strips to investigate residual soil P availability. A decrease in strip P with successive extractions followed th e equation: Strip P = a(extraction number)-b (r2 of 0.88-0.98). The rate of P release to strips (exponent b) decreased more rapidly as soil P sorption saturation increased (R2 of 0.79). Phosphorus saturation also accounted for 85% of the variation in the total amount of P released to strips from manured soils in 15 successive extractions (51-572 mg kg-1). Fractionation of soil P before and af ter strip extraction showed bicarbonate inorganic P contributed most of the P released to strips (46%). The above equation also described soil P release in several published field studies (r2 of 0.77-0.98). Thus, successive strip extraction of soil has th e potential to describe soil factors controlling the availability of residual P and identify soils where high P contents may be less buffered and, thus, decrease more rapidly than others under similar management conditions.

Abstract: Two types of compost, consisting of sweet sorghum bagasse with either sewage sludge or a mixture of pig slurry and poultry manure, were studied in a pilot plant using the Rutgers system. The total degradation of the piles as determined b y the weight loss of organic matter during the bio-oxidative and maturation phases accounted for 64% of the organic matter applied and followed a first-order kinetic function. Concentrations of total and organic N increased during the composting process a s the degradation of organic C compounds reduced the compost weight. Losses of N through NH3 volatilization were low, C:N ratio in the two composts decreased from 24.0 and 15.4 to values between 12 and 10. The humification index, the C:N ratio, fulvic:humic acid-like C, and cation exchange capacity proved to be the most suitable parameters for assessing the maturity of these composts.

Abstract: The chemical composition of Spirulina maxima and Phormidium sp. biomasses grown on pretreated and diluted swine wastewater was determined .Analyses were carried out on lyophilized samples and compared with data from mineral media (controls). Analyses of Phormidium grown on aeration-stabilized wastewater (ASSW) were: protein (Nx 625) 62%, lipids 11%, carbohydrates (calculated by difference) 16%. For Spirulina in the same effluent, data were: protein 36%, lipids 6% and carbohydrates 44%. No crude fiber was found in any of the samples. TThe resul ts suggest that Phormidium and Spirulina biomasses could be used as dietary supplements in animal feed, but further studies are needed to determine the nutritional value of the product.

Abstract: The conventional method for the digestion of residues using a mixture of nitric and perchloric acids was compared with the microwave procedure using both aqua regia and nitric acid as extractants, in order to determine which method fits better the routine measurements using inductively coupled plasma emission spectrometry (ICP-AES). Urban domestic wastes, swine and dairy manure and NIES pond sediment certified reference material were used as samples. Microwave extraction with aqua regia extracted higher amounts of metals from the certified pond sedimentreference material than the USEPA-SW 846-method 3051(nitric acid) and the conventional nitric-perchloric procedure, with a recovery greater than 90% for Fe, Mn, Zn, Cu, Pb and Cd; 76% for Ni and 61% for Cr. The extraction procedure with aqua regia method also presented statistically higher amounts of Fe, Mn, Zn, and Cr.

Abstract: A study was undertaken to investigate the composting of mechanically separated solid swine manure and ground lignite residues mixtures enriched with rice seed peels and ginned cotton residues. A set of odor-free compost piles, due to lignite addition, was installed, on site, at AFI KARAPATIS SA organic fertilizer factory at Zeli in central Greece. The findings of this study indicated that co-composting of solid swine manure and ground lignite (mixed at a ratio of 1:1 by volume) together with ginned cotton residues and rice seed peels resulted in improved composting and chemical composition characteristics compared to the mixture of solid swine manure and ground lignite alone or enriched with either ginn ed cotton residues or rice seed peels. Ground lignite allowed for the successful incorporation of the wet and malodorous swine manure into the compost process. Ginned cotton residues (at a 1:1 mixing ratio by volume) proved to be a bulking agent with exce llent 'insulating behavior' but with lower composting rates and increased EC and Na values in the final product.

Abstract: Four types of hydrolysis kinetics were tested for anaerobic degradation of complex organic matter using the generalized simulation model described earlier. The simulation dynamics from all types of hydrolysis kinetics of swine waste, sew age sludge and cattle manure for continuous-flow reactors at a defined SRT fitted the experimental data comparatively well. However, differences were found for particulate organic matter degradation over a wide range of SRT values.

Abstract: Primer systems for PCR amplification of different replicon-specific DNA regions were designed on the basis of published sequences for plasmids belonging to the incompatibility (Inc) groups IncP, IncN, IncW, and IncQ. The specificities of these primer systems for the respective Inc groups were tested with a collection of reference plasmids belonging to 21 different Inc groups. Almost all primer systems were found to be highly specific for the reference plasmid for which they were designed. In addition, the primers were tested with plasmids which had previously been grouped by traditional incompatibility testing to the IncN, IncW, IncP, or IncQ group. All IncQ plasmids gave PCR products with the IncQ primer systems tested. The results indicated that plasmids assigned to the same Inc group by traditional methods might be partially or completely different from their respective reference plasmids at the DNA level.

Abstract: The application of pig slurry, high in ammonia-nitrogen concentration, to agricultural land is a practice whose effect on soil microbial communities is poorly understood. The autotrophic ammonia-oxidising bacteria are an integral compone nt of the nitrogen cycle in soil and their activity will be affected by addition of nitrogenous fertilizer. Members of the genus Nitrosospira were shown by 16S rDNA-directed PCR to be present in both unamended and amended soils, regardless of the quantity of pig slurry applied. In contrast, members of the genus Nitrosomonas were detected by the same approach only in those soil plots that had received high loadings of slurry. These data support the view that nitrosospiras are ubiquitous as important membe rs of nitrifying populations in the environment. The direct detection of nitrosomonad DNA only in amended soils supports the hypothesis that these nitrosomonads become highly competitive under conditions analogous to laboratory enrichment cultures.

Abstract: A farm-scale treatment plant was studied during a year. Four different aeration cycles were tested in order to observe their effects on the removal of carbon material from pig slurry. The treatment plant performance was not significantly affected by a 60% induction of aeration times, from almost 20 h per day to 12 h per day. The high removal rates observed (over 95% in terms of BOD5) appeared to be related to the low aeration rates achieved through the intermittent operation of the aerat or. The removal of solid material was more variable. Percentage removals of total solids from the liquid were between 10 and 70%. Treatment of slurry consumed from over 150 kWh/day for 19.5 h of aeration per day to about 90 kWh/day for 12 h aeration per day. Aerobic slurry treatment cost US$2.50 per pig produced.

Abstract: The effect on silage quality of slurry type (pig or cow), rate of application of slurry (50, 100 or 200 m3 ha-1 year-1) and use of a bacterial silage inoculant, was assessed on grass from a long-term slurry experiment ensiled in laborato ry silos. There was no significant effect of slurry type on the quality of silage made from grass regrowths. However, on the basis of ammonia-N, lactate and volatile fatty acid contents, spring (first cut) grass treated with cow slurry in both years of th e study produced significantly poorer fermentation (P < 0.001) than silage from grass treated with pig slurry. Although increasing the rate of slurry application was shown to reduce fermentation quality in most treatments, this was seen as an effect of i ncreasing the total-N content of the herbage rather than of slurry application per se. It was also observed that slurry application had little impact on either the composition or diversity of herbage enterobacteria at harvest, and therefore probably upon subsequent fermentation.

Abstract: A farm-scale activated sludge treatment plant for separated pig slurry was operated with four different aeration cycles during a year, with the objective of optimising the process and producing an effluent with low nutrient and pathogen concentrations. The high nitrogen-removals observed (over 95%) appeared to be related to the denitrification achieved through the intermittent operation of the aerator. It was necessary to supply, on average, about 120 kWh/day (i.e.10 kWh/pig) in order to obtain a treated effluent with mean concentrations of 31.6 mg N-NH4/l and 77.6 mg NO3(-)N/l. The removal of phosphorus ranged from 20 to 90%. Concentrations between 25 and 60 mg PO4-P/l were obtained in the treated effluent. Mean percentage removals of metals were about 90% for Cu and 85% for Zn.

Abstract: Emissions of harmful gases, malodorous compounds and greenhouse gases emitted during composting of swine feces under continuous aeration were studied using a laboratory-scale composting apparatus. Concentrations of ammonia and sulfur compounds in the exhaust gas rose remarkably after starting and at every turning, and their changes reflected the odor concentrations calculated from sensory tests. Volatile fatty acids, in high concentrations at the start, were rapidly reduced within several hours from starting and did not rise again. Methane emission was observed within only 1 day from starting. Nitrous oxide repeatedly rose and fell after every turning, as did ammonia. Fr om the viewpoint of nitrogen loss during composting, however, the total amount of nitrous oxide emission seemed quite small compared with that of ammonia.

Abstract: Livestock production and manure handling decisions often have been treated in the literature as separate enterprises. Policymakers, too, have ignored the interactive nature of manure management by focusing on land application for nutrien t disposal. This study outlines a systems approach to describe the interrelated decisions producers face, using examples from North Carolina and Iowa that show how producers' attitudes toward manure management lead them to handle manure different) in diff erent regions.

Abstract: Eleven well-established, swine waste lagoon systems in the lower coastal plain of North Carolina were examined for evidence of seepage losses to the superficial aquifer. The sites were selected to represent three major soil systems in the areas of North Carolina with the highest swine populations. Elevated ammonium concentration was the strongest indicator of seepage. Estimated seepage losses were small on 45% of the systems studied. There was no apparent relationship between seepage loss rates and major soil system or style of construction. Rather, the dominant fac tor appeared to be the soil materials used in construction.

Abstract: Overland flow, on slopes of 5 and 11%, was used as a means of treating wastewater effluent from the second cell of a swine waste anaerobic lagoon system. Wastewater samples from both surface runoff and soil percolate (depths of 0.3, 0.9, and 1.5 m) were collected and analyzed for TKN-N, NH4-N, ON-N, NO3-N, pH, COD, K, EC, and TP-P. Using these data, along with the hydraulic loading rates and quantitative runoff collection, mass balances on the above parameters were calculated to determin e the surface treatment of the lagoon effluent. These mass balances suggest that overland flow is an excellent treatment system for liquid lagoon effluents with mass reductions of greater than 60% for all parameters on both slopes, except NO3-N, which had an approximate increase of 1.7 times on the 11% slope. Samples collected from the three lysimeter depths (soil percolate) suggest that NO3-N leaching from the plots may be a concern over an extended period of use.

Abstract: Four .8-ha pastures of bermudagrass (Cynodon dactylon [L.] Pers.) were fertilized with either 456 or 873 kg/ha of nitrogen (N) from swine lagoon effluent (two replicates per treatment) and grazed by steers over two summers. Within each p asture, steers received forage only, an energy source (corn), a mixture of corn and soybean meal, or a mixture of corn and blood meal via electronic Calan feeders. All supplements were offered at a level of 1.36 kg/d, and the soybean meal and blood meal s upplements provided similar quantities of protein. Weight gains were similar among supplemented steers, but supplemented steers gained faster (P < .05) than controls. Nitrogen fertilization level had no effect on steer gains, steer grazing days per hectare, or in vitro dry matter disappearance, NDF, and ADF of clipped forage samples. Plant protein and nitrate ion concentrations were greater (P < .06) in clipped forage samples receiving the higher N application rate.

Abstract: The present project was aimed at studying the effects of increasing loading of heavy metals on the anaerobic digestion of sewage sludge. The first experiment indicated that a sludge sample collected from Taipo Sewage Treatment Plant had a higher gas yield than one from Shatin Sewage Treatment Plant, which was possibly due to the higher content of heavy metals, including Cr, Cu, Ni and Zn, in Shatin sludge. Adding pig manure to both sludges raised their biogas yields. The second experiment of dosing different concentrations of the four metals to Taipo sludge showed that gas yields were severely inhibited at the highest concentration of each metal tested. The degree of toxicity of the four metals tested was in the order of Cr > Ni > Cu > Zn. The third experiment used water extracts of the digested materials for the cultivation of a microalga, Chlorella pyrenoidosa, and the results showed that 5% extracts of both sludges alone gave higher algal growth than the control (Bristol's medium).

Abstract: The persistence of five animal viruses, representing picorna-, rota-, parvo-, adeno-, and herpesviruses, and the coliphage f2 was determined in the field by exposing the viruses to different animal wastes and by adopting an established filter sandwich technique. This technique allows us to copy the natural state of viruses in the environment, where adsorption onto or incorporation into suspended solids may prolong virus survival. Using filter sandwiches either equipped with porous (15 nm in diameter) or poreless polycarbonate (PC) membranes, it was possible to differentiate between overall virus inactivation and the effect of virucidal agents that act through poreless PC membranes.

Abstract: A pot experiment was carried out using corn plants (Zea mays L.), in order to define the possible utilization of the concentrated pig slurry as an organic fertilizer, avoiding soil pollution caused by its chemical composition. Results ob tained showed that on a slightly loamy coarse sand soil an amount of 40 t ha-1 on fresh weight basis of concentrated pig slurry can eventually substitute mineral nitrogen and phosphate fertilization at planting. The effects of increasing amounts of this o rganic fertilizer on soil characteristics and corn fodder composition were also investigated.

Abstract: A sulfate-reducing bacterium isolated from swine manure used phenol as its sole source of carbon and energy. Sulfate was used as the electron acceptor. The major end product of phenol metabolism was acetic acid. For every mole of phenol degraded, almost 2 moles of acetic acid were produced. Acetic acid was not degraded further to CO2, indicating that this sulfate-reducing bacterium (SRB) is an incomplete oxidizer unable to carry-out the terminal oxidation of organic compounds. The SRB is olate also used chlorophenol as the sole source of carbon and energy. However, it did not use the chlorophenolic compounds containing two or more chlorine atoms, dichlorophenol and pentachlorophenol.

Abstract: Surface aeration of swine manure stored in anaerobic lagoons for odor control was experimentally studied in the laboratory. The effects of different aeration rates and depths on reduction in emission of odorous gases were determined for both continuous and intermittent aeration processes. Surface aeration was found to be effective for controlling odors of anaerobic lagoons. Continuous low rate aeration to maintain the dissolved oxygen in the surface liquid layer at 0.5 to 2.5 mg/L was effective for odor control but resulted in high ammonia emission rates. Intermittent aeration was found to be a feasible approach to minimize the energy requirement for aeration while still effectively controlling the odors of the manure.

Abstract: The changes in microbial properties, including total aerobic heterotrophs, O2-consumption rate, ATP content, dehydrogenase activity and microbial biomass C and N of the spent pig-manure sawdust litter were examined during further compost ing. The effects of three moisture levels, 50% (pile A), 60% (pile B) and 70% (pile C), on the composting process were also evaluated. Piles A and B had very similar trends of change in temperature and microbial properties during the composting period but pile C was significantly different. A moisture content of between 50 and 60% can be considered as the optimal moisture level for further composting of the spent litter. In general, the total aerobic heterotrophs, O2 consumption rate and ATP content of al l piles increased dramatically during the thermophilic stage of composting, but then decreased slowly and were maintained at lower levels at the end of the composting process.

Abstract: Two weight classes of growing-finishing swine were fed corn-soybean diets lower in protein and phosphorus to determine the reduction in nitrogen (N) and phosphorus (P) in swine waste when compared to pigs fed a conventional diet. For the two weight classes, total N waste was reduced 32% and 25% while total P excretion was reduced 39% and 38%. The experimental results were used to calibrate the NCPIG model to predict N and P excretion levels. Model excretion values for the same diets show ed similar trends in mineral reduction by diet, but were higher for urinary N when compared to observed values. The results of this project indicate that diet manipulation is a viable tool for U.S. swine producers in maintaining a sustainable U.S. swine industry.

Abstract: Forty eight and ninety six pigs weaned at 22.6 +/- 2.6 days, were allocated to two trials to study the effect of feeding post-weaning diets ad libitum, either as dry pellets (DF) or as meal mixed with water in the ratio 2.5:1 (LF). The t rials, lasting 28 days, differed only in the type of trough used to present the liquid feed to the pigs. In both trials the daily gain of LF pigs over the 4 weeks of the trial was significantly (P < 0.001) better than that of the DF pigs. Daily gains for the two treatment groups were respectively 428 and 343 +/- 15 g day-1 in Trial 1 and 454 and 397 +/- 10 g day-1 in Trial 2. The feed conversion ratio (FCR) (corrected to fresh weight of dry feed) of LF pigs was significantly poorer (P < 0.01) than that of DF pigs in both trials primarily as a result of feed wastage by the LF pigs. FCR for the DF and LF pigs was, respectively, 1.31 and 1.89 + 0.05 in Trial 1. In Trial 2 improvements in the trough design reduced the difference in FCR. FCR for the DF and LF treatments was 1.37 and 1.44 +/- 0.02 respectively. In Trials 1 and 2 LF pigs used on average 76% and 35% more water than DF pigs. LF pig produced 12% (Trial 1) and 5.7% (Trial 2) more effluent per unit of liveweight gain than DF pigs. Microbiological examination of the liquid feed system demonstrated that the system acted as a fermenter.

Abstract: The persistence of hepatitis A virus (HAV) was determined both in mixtures of septic tank effluent (STE) with dairy cattle manure slurry (DCMS) and in mixtures of STE with swine manure slurry (SMS). HAV was consistently inactivated more rapidly in the two types of mixed wastes than in STE alone or in the control Dulbecco's phosphate-buffered s aline (PBS). At 5 degrees C, the D values (time, in days, for a 90% reduction of virus titer) were 34.6 for the mixed STE and DCMS, 48.5 for the mixed STE and SMS, 58.5 for STE, and 217.4 for the Dulbecco's PBS control. At 22 degrees C, the D values were 23.0, 17.1, 35.1, and 90.1 for the four suspension media, respectively. A comparison of HAV inactivation in mixed wastes subjected to different treatments at the same pH and temperatures showed that the virus inactivation in the mixed wastes was related, at least in part, to microbial activity. In mixed STE and DCMS, the D values at 25 degrees C were 8.3 for raw mixed wastes, 15.1 for autoclaved mixed wastes, and 9.6 for bacterium-free filtrate of raw mixed wastes; D values at 37 degrees C were 6.8, 10.1, and 7.0 for these three suspension media, respectively. In mixed STE and SMS, the D values at 25 degrees C were 8.1 for raw mixed wastes, 14.3 for autoclaved mixed wastes, and 9.1 for bacterium-free filtrate of raw mixed wastes; the D values at 37 degrees C were 6.8, 9.4, and 6.9 for the three suspensions, respectively.

Abstract: The last three decades, pig breeding has evolved towards a specialised, large scaled, land independent bio-industry in the province of West-Flanders. Subsequently, in certain regions, very high amounts of liquid pig manure are produced e ach year. This pig slurry is used as a fertilizer at a rate which very often exceeds normal agricultural practices. Because of the nonequilibrium between the phosphorus crop requirements and the P-inputs, phosphates accumulate in the soil. However, the ph osphate sorption capacity of a soil is limited. Once the sorption capacity is exceeded, phosphates will start leaching through the soil profile. Since, during winter, in these areas, the groundwater table is situated at a depth of less than 1.0 m, phospha te breakthrough might take place.

NAL Call Number: QH540.J6

Abstract: Amendments with pig slurry containing dissolved organic matter (PSDOM) and herbicide coapplication are agronomical practices that can influence the mobility of herbicides through the soil profile, thus enhancing the risk of groundwater pollution. Batch equilibrium experiments were conducted on a clay loam soil to quantify the influence of these practices on the sorption and desorption of three s-triazine herbicides. Soil adsorption and desorption capability for atrazine was reduced when it was applied with the other two s-triazines in the batch experiment solution. The PSDOM treatment immediately after atrazine application had a greater enhancing effect on its desorption than treatment with a 0.01 M CaCl2 solution alone. To reduce the risk of groundwater s-triazine pollu tion, pig slurry should be applied to the soil before herbicide treatment.

Abstract: Two diets containing reduced levels of crude protein for both growing (35-65 kg) and finishing (65-95 kg) pigs were tested against standard commercial diets to determine changes in the odorants produced in fresh slurry. The experimental diets were formulated on a least cost basis using either a full commercial database or with restriction mainly to home-grown (UK) cereals and pulses. Major odorants responsible for pig odour from slurries were identified an d their concentrations determined using gas chromatography-mass spectrometry. Five out of 10 odorants from slurries produced by growing pigs were significantly lower (P < 0.05) in concentration for each of the low crude protein diets compared with the com mercial diet. Reducing dietary nitrogen and providing essential amino acids in an ideal protein ratio not only decreases the nitrogen excreted by the pig, but also reduces odorants produced in the resultant slurries.

Abstract: Laboratory-scale experiments were undertaken to investigate aeration and air stripping as methods for removing ammonia from swine wastewaters with high nitrogen concentrations. The effects of temperature, air to liquid flow ratio and pH were investigated using wastewaters with a range of solids concentrations and pH values. At a pH of 11.2, the aeration method took approximately 150 h to achieve 90% removal efficiency. This was achieved with temperatures of 22 degrees C and a low airflow rate of 1.15-1.60 l/min. At a comparable pH (11.5), the best results for the air-stripping method achieved 90% removal with only 7 h of treatment.

Abstract: Many agricultural fields on the semiarid Canadian prairies have areas of inherently low productivity associated with loss of soil quality due to erosion. This study compared the efficacy of various amendments in restoring productivity to a desurfaced fine-loamy, mixed Typic Haploboroll (Lethbridge series) in southern Alberta. In spring 1992, 14 amendment treatments (including livestock manures, crop residues, combinations of straw and chemical fertilizer, and fertilizer alone) were applied to a site where the Ap horizon (approximately 15-cm depth) had been mechanically removed to simulate erosion. The manures and crop materials were incorporated into the degraded surface on an equivalent dry-weight basis at 20 Mg ha-1. The overall best amendments were hog manure, poultry manure, and alfalfa hay.

Abstract: Gas dispersion from shallow manure storage pits was experimentally measured and mathematically modeled in a 1:6-scale ventilation chamber. The chamber represents a geometrically scaled model of a production swine grower facility. Gas injection was simulated from shallow pits using carbon dioxide (CO2). The results indicate significan t differences in gas concentration between the animal-occupied zone (AOZ) and human-occupied zones (HOZ), especially at ventilation rates representative of mild weather conditions. AOZ CO2 concentrations were 12 times higher than HOZ during minimum ventil ation conditions and six times higher during mild weather ventilation conditions.

Abstract: The effect of fertilizers on methane emission rates was investigated using an automated closed chamber system in Chinese rice fields (Hunan Province). Each of three experiments compared two fields treated with a first uniform fertilizer dose and a second fertilizer dose which was different for each of the two fields. The uniform fertilizer doses for both fields in each experiment comprised mineral (experiment 1), organic (experiment 2) and combined mineral plus organic components (experiment 3). In all three experiments the second fertilizer dose comprised organic amendments for field 1 and no organic amendments for field 2. The rate of increase in methane emission with a given amount of organic manure was found to depend on the total amount of organic manure applied. A single dose of organic manure increased the emission rates by factors of 2.7 to 4.1 as compared to fields without organic manure (experiment 1).

Abstract: The determination of manure loading rates for crop production is complicated by the temporal variability in manure nutrient concentrations and the difficulty in obtaining representative samples on which to base application rates. The var iation in nutrient concentrations in liquid swine manure obtained from an agitated anaerobic lagoon was examined during application to experimental plots. Grab samples were collected from a lagoon approximately two to four weeks prior to application and a nalyzed for nitrogen (N), phosphorus (P), and potassium (K). Based on the preliminary P analyses, swine manure application rates were computed. Manure from the lagoon was surface-applied to corn plots to provide P rates of 15, 30, and 60 kg P/ha. During a pplication, each tankload of manure was sampled to determine P rates for each plot. The solids content of each manure load was highly variable as were the total concentrations of manure N and P. Potassium content of the manure was also related to the soli ds content, although not to the same extent as N and P. Manure application resulted in P rates of 17, 32, and 49 kg P/ha in 1992, while the 1993 rates were 5, 11, and 22 kg P/ha.

Abstract: The incorporation of livestock into agricultural systems ensures a more sustainable agriculture. Sustainable swine production systems are defined as those that combine production and management techniques to enhance profit and improve th e ecological and socioeconomic surroundings. At the interface of sustainable agriculture and swine production are several levels of issues. Four levels of issues are the farm, the rural community, the society or consuming public, and the ecosystem or environment. By examining each level, long-term sustainability issues for U.S. swine production emerge.

Abstract: Sphagnum peat moss, floating on swine manure in storage, was tested during three summers as an N conservation method in experimental tanks which measured 0.75 m in diameter and 3.0 m deep. Three depths of floating peat moss (0, 10, and 2 0 cm) were tested. The swine manure was analyzed prior to the tests and after 14 wk of storage, from June to mid-September. An average of 54, 60, and 76% total N conservation was observed for the respective treatments. Twenty centimeters of peat moss significantly reduced manure N losses and manure evaporation during storage.

Abstract: Swine manure anaerobic lagoons have sometimes been constructed in sandy soil without clay liners. Two swine manure, anaerobic lagoons located in sandy, coastal plain soil were investigated. Both continued to have significant seepage afte r 3.5 to 5 years of receiving waste. Monitoring wells indicated broad seepage plumes, and much variation in concentrations of several parameters with well location, time, and depth of well. The variations indicate the difficulty of accurately monitoring and quantifying seepage transport of nutrients, and the complexity of developing groundwater transport models to accurately predict transport and transformations of chemical compounds, particularly ammonium and nitrate nitrogen, at various dist ances from the lagoon.

Abstract: In order to solve an actual problem existing in Cuba in swine waste treatment plants, a system called 'high-rate-modified-anaerobic-process' (HRAMP) was developed. It consisted mainly of the incorporation of a liquid anaerobic reactor (LAR) into the existing plants to treat the supernatant liquid coming from the sedimentation unit. In this work the main results were obtained over a 3-year period. A laboratory-scale comparison with conventional processes was made which showed that HRAMP was 16-50% more efficient than conventional plants. This better operation was due to the inoculum, that would be added daily to LAR from the anaerobic sludge-digester that already exists in piggery waste treatment plants.

Abstract: In continuously stirred tank reactor experiments, with manure as substrate at thermophilic temperatures, the use of volatile fatty acids (VFA) as process indicators was investigated. Changes in VFA level were shown to be a good parameter for indicating process instability. The VFA were evaluated according to their relative changes caused by changes in hydraulic loading, organic loading or temperature. Butyrate and isobutyrate together were found to be particularly good indicators. Butyra te and isobutyrate concentrations increased significantly 1 or 2 days after the imposed perturbation, which makes these acids suitable for process monitoring and important for process control of the anaerobic biological system. In addition it was shown in a batch experiment that VFA at concentrations up to 50 mM did not reduce the overall methane production rate. This showed that VFA accumulation in anaerobic reactors was the result of process imbalance, not the cause of inhibition, thus justifying the us e of VFA as process indicators.

Abstract: Inappropriate fertilization practices in regions where livestock manure exceeds crop requirements may cause pollution by NH4+-N) during snowmelt. Annual and seasonal NH4+-N losses were evaluated for three consecutive years from 45 m2 cor n (Zea mays L.) and timothy (Phleum pratense L.) and red and white clover (Trifolium repens L.) erosion plots that had annually received the recommended chemical fertilizer rates of 180 and 55 kg N ha-1, respectively, plus hog manure at twice those rates. Total N applications for corn and forage were 540 and 165 kg ha-1 except for a check plot receiving only fertilizer. The hog manure was surface-applied in three different ways: all in the fall, all in the spring, and in a split application with about one-half in each season. Total NH4+-N losses in both runoff and drainage water from autumn application were greater than for the two other application methods for corn and the forages.
