Effects of curcumin on growth performance and blood biochemical indices of hybrid offspring of Boer and Huai goats under heat stress
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.
