粉碎粒度对豆粕在绵羊瘤胃内降解和消化的影响
Effects of Grinding Particle Size on Degradation and Digestion of Soybean Meal in Rumen of Sheep
摘要
Abstract
To provide academic basis and technical parameters of fitting soybean meal (SBM) particle size crushed for feed processing of ruminant, four mature male Merino sheep with rureen cannula were used to measure the degradability of DM and CP of thin, mid, nature (not crush) and thick particles of SBM (particle diameters were 0.60～1.28, 1.28～2.50, 0.80～5.00 and 2.50～5.00 mm, respectively) in rumen and apparent digestibility of DM and CP of 4 particle SBM diets by nylon bag technique and total feces collection method using 4×4 Latin square design.The results revealed that rumen de-gradability of DM and CP of SBM increased with diminishing of particle size of SBM.The apparent digestibility of DM(P> 0.05) and CP (P<0.05) of thick particle SBM diet was lower than those of thin, mid and nature particle SBM diets, but there were no significant differences among three treatments.Rumen degradability of DM and CP of not crushing SBM were significantly lower than those of thin and mid particle SBM.It was concluded that not crushing SBM was thought to be di-rectly used in production of feed processing of ruminant due to its higher efficiency of DM and CP utilization, and expense saved for crushing in processing.关键词
