This study investigated the effects of enzymatic hydrolysate of cottonseed protein (EHCP) supplementation on the growth performance and intestinal health of nursery pigs in Thailand. A total of 180 newly weaned piglets were randomly allocated to 3 groups with 6 replicates in each group and 10 piglets per replicate. Nursery pigs were fed three diets containing 0, 1%, and 1.5% EHCP for 28-63 days of age. The results indicated that 1% EHCP supplementation increased average daily feed intake (ADFI) and average daily gain (ADG) and decreased feed conversion rate (FCR) in the numerical, suggesting that appropriate EHCP supplementation could numerically improve growth performance of nursery pigs in Thailand. Moreover, 1% EHCP supplementation significantly decreased intestinal crypt depth and diarrhea incidence and increased intestinal villus height to crypt depth ratio and fecal consistency, suggesting that optimum EHCP supplementation could improve intestinal morphology and decreased diarrhea incidence of nursery pigs in Thailand. Furthermore, 1% EHCP supplementation significantly improved intestinal glutathione (GSH) level and superoxide dismutase (SOD) activity and indicated that optimal EHCP supplementation could improve intestinal antioxidant capacity of nursery pigs in Thailand. Optimum EHCP supplementation numerically increased growth, significantly decreased diarrhea incidence, significantly improved intestinal morphology and antioxidant capacity of nursery pig in Thailand.
本研究调查了补充棉籽蛋白酶解物（EHCP）对泰国保育猪生长性能和肠道健康的影响。总共180头新断奶仔猪被随机分为3组，每组6个重复，每个重复10头仔猪。保育猪在28至63日龄期间饲喂三种分别含有0%、1%和1.5% EHCP的日粮。结果表明，补充1% EHCP在数值上提高了平均日采食量（ADFI）和平均日增重（ADG），并降低了饲料转化率（FCR），这表明适当补充EHCP在数值上可提高泰国保育猪的生长性能。此外，补充1% EHCP显著降低了肠道隐窝深度和腹泻发生率，并提高了肠绒毛高度与隐窝深度比值以及粪便稠度，这表明最佳补充EHCP可改善泰国保育猪的肠道形态并降低腹泻发生率。此外，补充1% EHCP显著提高了肠道谷胱甘肽（GSH）水平和超氧化物歧化酶（SOD）活性，这表明最佳补充EHCP可提高泰国保育猪的肠道抗氧化能力。最佳补充EHCP在数值上提高了泰国保育猪的生长，显著降低了腹泻发生率，显著改善了肠道形态和抗氧化能力。
