| 摘 要： | 研究旨在评定猪对脱酚棉籽消化能和粗蛋白表观消化率,并比较脱酚棉籽蛋白(DCP)与豆粕(SBM)之间差异。选用体重(36.2±1.6)kg的杜×长×大三元杂交猪6头,采用套算法、双3×3拉丁方试验设计,试验日粮分别为脱酚棉籽蛋白日粮、豆粕日粮和基础日粮,每个拉丁方阶段包括5 d预饲期、5 d正式期,整个试验共30 d。结果表明,脱酚棉籽蛋白、豆粕消化能含量分别为12.41 MJ/kg、13.62 MJ/kg。脱酚棉籽蛋白、豆粕中粗蛋白表观消率化分别为73.35%、82.05%,表观可消化粗蛋白含量分别为37.92%、35.45%。脱酚棉籽蛋白是新型蛋白质原料,其消化能含量为豆粕的91.11%,粗蛋白表观消率化为豆粕的89.39%,可消化粗蛋白含量为豆粕的106.99%。脱酚棉籽蛋白在猪饲料中的应用具有广阔的前景。

| Abstract: | This study aimed to assess the digestible energy content and crude protein apparent digestibility of degossypolled cottonseed protein(DCP) for swine,and compare the differences between DCP with soybean meal(SBM).By six BW(36.2±1.6) kg of pigs,using sets of algorithms,double 3×3 Latin square experimental design,the experimental diets were DCP diet,SBM diets and basal diet,each Latin square stage including 5 d pre-feeding period and 5 d official period of the trial.The whole trial lasted 30 d.The results showed that DCP digestible energy content was 12.41 MJ/kg,SBM was 13.62 MJ/kg.Crude protein apparent digestibility of DCP was 73.35%,SBM was 82.05%.And apparent digestible crude protein content were 37.92%,35.45% respectively.In conclusion,DCP is a new ingredient.Comparing with SBM,the digestible energy content is 91.11%,crude protein apparent digestibility is 89.39%,apparent digestible crude protein content is 106.99%.Degossypolled cottonseed protein is available in a wide range of applications for pig feed. |
