摘　　要：本试验研究饲料肽对仔猪后期的生长、氨基酸利用率和肠道消化酶活性的影响。选用体重近似的96头(38±2)日龄的杜长大仔猪,随机分为4个处理组,每个处理4个重复。4个处理分别为:含6%鱼粉的对照组(C)、6%鱼粉和2%血浆蛋白粉的日粮组(T1)以及分别加1%和2%饲料肽等蛋白取代喷雾干燥血浆蛋白粉的试验日粮组(T2和T3),试验21 d结束时进行屠宰试验。结果表明:血浆蛋白粉和饲料肽可显著提高仔猪的平均日增重和日粮必需氨基酸消化率(P<0.05),二者之间的生产性能和日粮必需氨基酸消化率差异不显著(P>0.05)。日粮处理对仔猪肠道消化酶活性没有显著影响(P>0.05)。这表明饲料肽部分取代喷雾干燥血浆蛋白粉对仔猪后期的生长、氨基酸消化率和消化酶活性无显著影响。This experiment was conducted to investigate the effects of feed peptides （FP）on growth performance ,apparent ideal digestibility of essential amino acid （EAA）, and digestive enzyme activity of piglets.Ninety six （38±2） day old pigs （DurocxLandraeexLarge Yorkshire）were randomly allocated to four dietary treatments with four replicates.The four treatment diets included one control diets supplemented with 6 % fishmeal （C）,diets supplemented with 2 %0 spray-dried plasma protein （SDPP）and 6 % fishmeal （T1）,and diets supplemented with 1% and 2 % feed peptides to replace SDPP on protein basis respectively （T2 and T3）.At the end of the experiment,one pig of each replicate was slaughtered for the determination of the apparent ideal digestibility of EAA.The results showed that the average daily gain and apparent ideal digestibility of EAA of T1,T2 and T3 were higher than that of C （P 〈 0.05）,but the growth performance,apparent ideal digestibility of EAA in T1 ,T2,and T3 had no significant difference（P 〉 0.05）.No significant effect was found in digestive enzyme activity due to dietary replacements （P 〉 0.05）.In conclusion,the partial replacement SDPP with FP had no adverse effect on growth performance, EAA digestibility and digestive enzyme activity of pigs.
