【Abstract】 The experiment on sheep showed,the slow released additive would be dissolved in 180~196 day in rumen completely and its dissolving rate was proportional,The slow released additive had some characteristic,such as large buffer copacity,no poisonous side effect ,safi-reliable feeding,high biological effective value and significant feeding effect.When young sheep were fed the additive,within the period of trial-term,gain weight increased by 15.74%~31.75%(P<0.05),and the incremental rate ofbody lengrh,chest measuriment,wool length and greasy weight were 12.27%,12.11%,10.38%and 8.19%higher than that of control,respectively,and all the difference are statistically significant.更多还原
