Campbell, T.E., P.A. Harris, H.C. Doughty, and M.N. Sillence (2005). Effect of chaff quantity and length on rate of intake in horses fed a concentrate diet. Asia Pacific Journal of Clinical Nutrition 14(Suppl.): S80.
Abstract: Background - Grains are commonly fed to horses that have a high energy requirement. However, large quantities and fast consumption of grain can result in disorders such as laminitis, colic, tying-up, gastric ulcers and fractious behaviour. Thus, controlling the rate of grain intake is an important aspect in managing equine nutrition. Objectives - To measure the relationship between chaff quantity and length and the rate of intake of oats. Design - Each morning, six geldings (BW 479 +/- 18 kg) were fed a constant meal of oats at 3 g/kg bodyweight in combination with either longer ground wheaten chaff (4 cm), or short chopped wheaten chaff (< 2 cm) at one of five different addition rates in a random latin square design. Ryegrass/clover hay was provided each afternoon to meet maintenance energy requirements. Outcomes - Rate of intake varied with chaff quantity (P <0.001, ANOVA for repeated measures), but was not affected by chaff length. A maximal decrease in rate of intake occurred at the addition rate of 50% chaff. Conclusion - Relative to earlier studies a large amount of chaff was required to decrease rate of intake. It is not clear whether this is due to meal size, chaff type, or chaff processing method. Chaff length appeared to have no effect on rate of intake. However, the long chaff was ground and not chopped, which would have decreased the surface area and chewing required for ingestion. Further research is required to standardise a method of measuring rate of intake and to explore differences in chaff properties.

Abstract: Four donkeys and four ponies were fed molassed dehydrated alfalfa or oat straw, either ad libitum or restricted to about 70% ad libitum intake in a Latin-square design for four periods of 21 d. Measurements of apparent digestibility and gastrointestinal transit time were made on the last 7 d of each period. When the forages were provided ad libitum, all animals ate significantly (P < 0.01) more of the alfalfa than of the oat straw. Ponies consumed significantly (P = 0.007) more of both diets per unit live weight than donkeys. Higher apparent digestibilities of dietary DM, energy and fibre fractions were seen in donkeys, at both levels of feeding, compared with the ponies. This partly compensated for the lower intakes by the donkeys when fed ad libitum. When intake of alfalfa was restricted, the apparent digestibility of DM was higher compared with the corresponding values when fed ad libitum, but the reverse was true for straw. This may be because restriction of a low-quality diet reduced selection of the more digestible parts of the forage. Donkeys and ponies consumed more energy and protein than required when fed alfalfa ad libitum. Both oat straw treatments provided insufficient protein to meet the predicted requirements of ponies and donkeys. Straw intakes ad libitum exceeded the estimated energy requirement for ponies by 34-51%, but donkey energy requirements were only just met. When the amount of straw offered was restricted, 78-90% of the estimated energy requirement for donkeys was met compared with 90-105% for the ponies.
