日粮蛋白质水平对陕北白绒山羊空怀期母羊生产性能和产绒性能的影响
Effects of Protein Levels on Production Performance and Wool Trait in Shaanbei White Cashmere Goat in Non-pregnancy
摘要
Abstract
Thirty-six one-year-old and healthy female goats with similar body weight were arranged into 4 groups to study the effects of dietary protein levels (7.79％,8.45％,9.79％,10.40％) on production performance and wool traits in Shaanbei White Cashmere Goat.The result showed that dietary protein levels had no significant (P＞0.05) effect on live body gain and cashmere diameter.With the increasing of dietary protein levels,the fleece growth rate increased at the begining and then decreased.There was significant (P＜0.05) decrease in wool growth rates when the protein level was above 10.40％.In conclusion,proper levels of CP in diets for Shaanbei White Cashmere Goat in non-pregnancy was 8.45％ to 9.79％ (air-dry basis).关键词
