Effects of starter feed with different proportions of alfalfa on growth performance,serum indexes,and intestinal development of lambs aged 15 to 54 days
试验旨在探讨不同比例苜蓿开食料对15～54 日龄湖羊羔羊生长性能、血清指标和肠道发育影响.试验选取48只体重(4.22±0.35)kg第二胎次湖羊羔羊,随机分为3组,每组4个重复,每个重复4只羊,各组分别饲喂含有10％、20％和30％苜蓿的开食料.试验期40 d.结果显示:54日龄时,30％苜蓿组羔羊体重高于其他组(P＞0.05).45～49日龄时,20％苜蓿组的平均日采食量(ADFI)显著高于10％苜蓿组(P＜0.05).20％和30％苜蓿组的肿瘤坏死因子-α(TNF-α)、白细胞介素-4(IL-4)和白细胞介素-6(IL-6)的含量显著低于10％苜蓿组(P＜0.05),20％和30％苜蓿组血清总抗氧化能力(T-AOC)和谷胱甘肽过氧化物酶(GSH-Px)活性显著高于10％苜蓿组(P＜0.05).10％苜蓿组肠道的总抗氧化能力(T-AOC)和超氧化物歧化酶(SOD)活性显著高于其他组(P＜0.05).20％和30％苜蓿组磷酸激酶(CK)活性显著低于10％苜蓿组(P＜0.05),20％和30％苜蓿组乳酸脱氢酶(LDH)活性显著高于10％苜蓿组(P＜0.05).20％苜蓿组十二指肠的绒毛长度、30％苜蓿组十二指肠隐窝深度显著高于其他组(P＜0.05).研究表明,饲喂含有10％和20％苜蓿的开食料能够提高羔羊机体免疫力和抗氧化能力,促进十二指肠发育,建议15～54 日龄羔羊开食料中苜蓿含量不超过20％.
The experiment aimed to explore the effects of starter feed with different proportions of alfalfa on the growth performance,serum indexes,and intestinal development of Hu sheep lambs aged 15 to 54 days.A total of 48 Hu sheep lambs with an average body weight of(4.22±0.35)kg from the second parity twins were randomly divided into three groups,with four replicates per group and four sheep per replicate.Each group was fed starter feed containing 10％,20％,and 30％alfalfa,respectively.The experiment lasted for 40 days.The results showed that at 54 days of age,the body weight of lambs in the 30％alfalfa group was higher than that of the other groups(P＞0.05).From 45 to 49 days of age,the average daily feed intake(ADFI)of the 20％alfalfa group was significantly higher than that of the 10％alfalfa group(P＜0.05).The levels of tumor necrosis factor-α(TNF-α),interleukin-4(IL-4),and interleukin-6(IL-6)in the 20％and 30％alfalfa groups were significantly lower than those in the 10％alfalfa group(P＜0.05),and the serum total antioxidant capacity(T-AOC)and glutathione peroxidase(GSH-Px)activity in the 20％and 30％alfalfa groups were significantly higher than those in the 10％alfalfa group(P＜0.05).The total antioxidant capacity(T-AOC)and superoxide dismutase(SOD)activity in the intestines of the 10％alfalfa group were significantly higher than those in the other groups(P＜0.05).The creatine kinase(CK)activity in the 20％and 30％alfalfa groups was significantly lower than that in the 10％alfalfa group(P＜0.05),and the lactate dehydrogenase(LDH)activity in the 20％and 30％alfalfa groups was significantly higher than that in the 10％alfalfa group(P＜0.05).The villus length of the duodenum in the 20％alfalfa group and the crypt depth in the duodenum of the 30％alfalfa group were significantly higher than those in the other groups(P＜0.05).The study indicates that feeding starter feed containing 10％and 20％alfalfa can enhance the body's immune and antioxidant capabilities,and promote the development of duodenal tissue.It is recommended that the content of alfalfa in the starter feed for lambs aged 15 to 54 days should not exceed 20％.
