| Abstract | S816.4; 研究旨在通过全收粪法测定酶解棉籽蛋白(enzymatic hydrolysis of cottonseed protein,EHCP)生长猪有效能值,同时通过T型瘘管手术测定生长猪回肠末端氨基酸消化率.试验一:选取体重为(12±0.5)kg的"杜×长×大"健康去势公猪18头,随机分成对照组、65%EHCP组和85%EHCP组,每组6个重复,每个重复1头猪.试验二:选取体重为(15±0.3)kg的"杜×长×大"健康去势公猪18头,于回肠末端进行T型瘘管手术,随机分成对照组(无氮饲粮)、65%EHCP饲粮组和85%EHCP饲粮组,每组6个重复,每个重复1头猪.结果表明:①65%EHCP组生长猪消化能值和代谢能值分别为14.89 MJ/kg和13.52 MJ/kg;85%EHCP组生长猪消化能值和代谢能值分别为16.39 MJ/kg和14.57 MJ/kg.②65%EHCP饲粮组的氨基酸表观和标准回肠消化率分别为69.84%～93.57%和76.20%～94.28%.85%EHCP饲粮组的氨基酸表观和标准回肠消化率分别为70.89%～95.99%和81.64%～97.38%.综上所述,85%EHCP的消化能、代谢能和必需氨基酸的回肠末端消化率高于65%EHCP,为EHCP在猪饲养中的应用提供了理论参考. |

| Abstract_FL | The objective of this study was to deter-mine the effective energy value of enzyme hydroly-sis of cottonseed protein(EHCP)in growing pigs by means of the Total fecal collection method,and to study amino acid terminal ileum digestibility by simple T-cannulas operation.In experiment one,eighteen healthy castrated(Duroc×Landraces×Yorkshire)boars with body weight of(12±0.5)kg were selected.The pigs were randomly divided into con-trol group(basal diet),65%EHCP group,and 85%EHCP group with six replicates per group and one pig per replicate.In Experiment two,eighteen healthy castrated(Duroc×Landraces×Yorkshire)boars weigh-ing(15±0.3)kg were selected to perform simple T-cannulas in the terminal ileum.In a randomized block design,the pigs were divided into control group(N-free diet),65%EHCP diet group,and 85%EHCP diet group,with six replicates per group and one pig per replicate.The results showed as follows:① under 65%EHCP feeding basis,the ME and ME of growing pigs were 14.89 MJ/kg and 13.52 MJ/kg,respectively.The digestive energy and metabolizing energy values of growing pigs with 85%EHCP feed-ing basis were 16.39 MJ/kg and 14.57 MJ/kg,respectively.② The AID and SID of 65%EHCP amino ac-ids were 69.84%-93.57%and 76.20%-94.28%,respectively.The AID and SID of 85%EHCP were 70.89%-95.99%and 81.64%-97.38%,respectively.In conclusion,the digestitive energy,metabolic en-ergy,and terminal ileal digestionability of essential amino acids of 85%EHCP were higher than those of 65%EHCP,providing a theoretical reference for the application of EHCP in pig feeding. |
