摘要
本研究旨在评价不同添加剂量的姜黄素对热应激条件下波槐杂交羊生长性能及血液生化指标的影响.试验将 30 头体重为(28.03±0.32)kg的健康波槐杂交公羊随机分为 3 组,每组 10 只,分别饲喂 0 mg/头/d(CON组)、450 mg/头/d(CUL组)、900 mg/头/d(CUH组)的姜黄素,预饲期 15 d,正试期 60 d.结果显示:(1)CUL组波槐杂交羊的平均日增重和总增重显著高于CON和CUH组(P＜0.05).(2)CUL组波槐杂交羊血清中的总蛋白和球蛋白含量显著高于CON和CUH组(P＜0.05).(3)CUL组杂交羊血清中的免疫球蛋白G含量显著高于CON和CUH组(P＜0.05),CON和CUH组杂交羊血清中的丙二醛含量显著高于CUL组(P＜0.05).综上所述,日粮中添加 450 mg/头/d的姜黄素可以改善热应激条件下波槐杂交羊的应激状态和健康状态,并进一步提高生长性能.
Abstract
This study aims to evaluate the impact of varying doses of curcumin on the growth performance and blood biochemical indices of Dorper×Hu crossbred sheep under heat stress conditions.The trial involved 30 healthy Dorper×Hu crossbred rams,each weight with(28.03±0.32)kg,which were randomly divided into three groups of 10.Each group received a different daily curcumin dosage:0 mg/head/day(CON group),450 mg/head/day(CUL group),and 900 mg/head/day(CUH group).The experiment included a 15-day pre-feeding period followed by a 60-day main trial period.The results indicated that:(1)The average daily gain and total weight gain of the CUL group were significantly higher than those of the CON and CUH groups(P＜0.05).(2)The levels of total protein and globulin in the serum of the CUL group were significantly higher than those in the CON and CUH groups(P＜0.05).(3)The serum immunoglobulin G levels in the CUL group were significantly higher than those in the CON and CUH groups(P＜0.05),while the malondialdehyde levels in the serum of the CON and CUH groups were significantly higher than those in the CUL group(P＜0.05).In summary,supplementing the diet with 450 mg/head/day of curcumin can improve the stress response and health status of Dorper×Hu crossbred sheep under heat stress,thereby enhancing their growth performance.
