NAL Call Number: S539.5 J68

Abstract: Management and marketing are key components of success and profitability of any beef cow/calf operation. There are many factors involved in management of a cow/calf operation and in marketing its products. These factors interact in a complex manner making any attempt to separate their effects, when predicting profitability as a function of management and marketing decisions, difficult and impractical. Therefore, we developed a simple computer program (CowCost, runs under Windows95 or Windows98) to enable producers to evaluate various management practices and their potential impacts on profitability. The program links the management and marketing variables commonly found in a cow/calf operation in an interactive way. This results in an immediate response to any changes in the input data and, therefore, provides the users with the ability to test many "what if" scenarios and their subsequent effects on profitability. In turn, producers can check many different scenarios, prices, costs, and how they will affect the value of a cow. It is both a program to evaluate management ideas and profit potential of chosen scenarios. The program considers money borrowed to buy a cow, duration of the loan, cost of the cow, salvage value of the cow, yearly cow cost, calf weaning weight, calf price per pound and other variables to evaluate profit potential. Varying any one of these gives insight to management practices that could be emphasized to increase profit. The program allows investigation of the effects of costs relative to other inputs in decisions about purchasing cows.

Abstract: Determining which management practices to focus on to improve profitability is a major challenge in any cow/calf operation. We used CowCost management simulation to evaluate the relative importance the major factors. The software generated 50 000 different management scenarios using values that were generated randomly, but within reasonable ranges of typical western cow/calf operations. Management factors studied by the model included the original cost of the cow, interest rate paid on money borrowed to buy the cow, salvage value of the cow at the end of her production life, percentage of calves the cow might wean, yearly cost per cow of the ranching operation, average weaning weight of the calf, and the average price brought by the calf. The model assumes calves will be sold at weaning and not held as yearlings. The model used these management factors to predict profit or loss, and to gauge the relative importance of the management practice. All scenarios were for one cow with an assumed production of 8 yr. Correlation analysis of the data showed that yearly cost was the most influential in determining profit or loss. The money received per pound of calf was next most influential. Weaning weight was the third most influential and weaning percent is fourth. The original cost of the cow, interest rates, and salvage value of the cow were far less influential on profit loss. While these final items, especially the cost of the cow and interest rate, receive a great deal of attention from most producers, they may not deserve that much attention, especially compared with other management inputs.

NAL Call Number: S605.5 B5

Abstract: The problems of beef production, including concerns about animal welfare, undesirable environmental effects, inability to be economically viable without subsidies from the public purse, and, recently, in the light of the B.S.E. crisis, possible concern for public health, are discussed. The criteria for improved animal welfare, including reduced behavioural restriction, are examined in order to work towards developing “ethologically sound” environments. The criteria for assessing the ecological effect of the beef producing enterprise are also outlined. One suggested way of reducing environmental and animal welfare problems is the production of suckled beef on ecological farms if this can be economic.

Abstract: This paper describes an ethological and ecological management system for rearing beef cattle. Data on the management, production and economic performance of a herd of double-suckled South Devon cattle on a farm within the Dartmoor National Park, UK, were collected from 1990 to 1996 and were compared to figures given in the University of Exeter”s Farm Management Handbook for Premium Farms. Data from the experimental farm included records on 62 cows which gave birth to 60 calves and reared an additional 53 calves. The ecological criteria were mainly fulfilled by the management system and the gross margin per head (pounds sterling158.90-818.18) was generally higher than that of the conventional farms (pounds sterling366.10-555.34).

NAL Call Number: 41.8 C163

Abstract: A dynamic deterministic model for simulating beef cattle production systems is developed to evaluate the effects of production traits and management strategies on the bioeconomic efficiency of beef production systems. The model, named Alberta Beef Production Simulation System (ABPSS), is composed of four major submodels: herd inventory, nutrient requirement, forage production, and economic submodels. The herd inventory submodel is used to simulate population dynamics and feed requirements in the herd. The nutrient requirements submodel is mainly based on the 1996 version of the National Research Council (NRC). It is used to evaluate nutrients and feed requirements for calves and cows depending on their physiological status (maintenance, growth, lactation and gestation) and the climatic condition. The forage production sub-model is used to predict forage growth rate, cattle grazing rate, available forage biomass and total hectares required for grazing. The economic submodel measures bioeconomic efficiency, as net return per cow, by subtracting total cost from total return. The nutrient requirements predicted by ABPSS were compared with those recommended by the NRC for testing. The results that were predicted by the NRC model and ABPSS model were similar, as expected. Sensitivity analyses showed that cow mature weight, milk production, calf weaning weight and feed prices were the most critical input parameters in the model. It must be noted that the model was developed based on available experimental results and data from the literature and, due to the unavailability of a suitable data set, the model could not be validated. We suggest that the ABPSS has the potential for providing a use method for simultaneous consideration of many factors in an integrated system, which could be helpful to beef cattle extension specialists and cow-calf production managers for assessing the potential effects of different management and selection strategies on bioeconomic efficiency.
