本试验通过采集我国多个地区脱酚棉籽蛋白样品,分析脱酚棉籽蛋白常规成分,测定其生长猪消化能( DE),建立脱酚棉籽蛋白常规成分与生长猪DE之间的关系。试验选用体重相近[(32.0±2.3)kg]的三元杂交(杜×长×大)健康去势公猪12头,采用2个6×6拉丁方试验设计,包括1种基础饲粮和11种脱酚棉籽蛋白替代18%基础饲粮的试验饲粮。采用全收粪法和套算法结合测定脱酚棉籽蛋白猪DE值,并将脱酚棉籽蛋白的常规成分与猪DE值进行相关和回归分析,建立脱酚棉籽蛋白猪DE预测模型。结果表明,11种脱酚棉籽蛋白风干状态下猪DE值为(11.67±0.82)MJ/kg,不同来源的棉籽生产的脱酚棉籽蛋白猪 DE 值差异不显著( P>0.05)。脱酚棉籽蛋白猪 DE 最佳预测模型(干物质基础):DE=15.40-0.27ADF( R2=0.91, RSD=0.27)和DE=14.88-0.29ADF+0.25EE( R2=0.94,RSD=0.22),式中,ADF为酸性洗涤纤维,EE为粗脂肪。ADF为脱酚棉籽蛋白猪DE最佳预测因子。

The digestible energy( DE)and analyzed proximate composition and the prediction model of DE of degossypolized cottonseed protein( DCP)by its analyzed proximate composition for growing pigs were investi-gated in this experiment,and DCP were collected in main producing areas of China. A total of 12 Duroc × Landrance×Largewhite castrate male pigs with(32.0±2.3)kg initial body weight were allotted to two 6×6 Latin square designs. The diets included 1 kind of basic diet and 11 kinds of trial diets which were replaced 18% of the basic diet by DCP. The DE of 11 kinds of DCP was determined with total feces collection method and difference method. The regression equation was established on the basis of the correlation between DE and proximate composition of DCP. The results showed that the mean of DE( air-dry basis)of DCP for pigs was (11.67±0.82)MJ/kg,and there were no significant differences in DE of DCP from different areas. The rec-ommended prediction models( DM basis)of DCP for pigs were DE=15. 40-0. 27ADF( R2=0. 91,RSD=0.27)and DE=14.88-0.29ADF+0.25EE( R2=0.94,RSD=0.22). The appropriate predicting factor was ADF.
