Abstract

The purpose of this study was to investigate the effects of different protein levels in late pregnancy on ewe and lamb growth performance, serum biochemical indexes. Thirty-three ewes (46.4 ± 1.38 kg initial weight) were randomly divided into 3 groups, with 11 ewes in each group. The protein levels of three diets formulated to provide components to meet 10.00 MJ/kg ME requirements diets were: 10.12%, 11.26%, 12.4%. Ewes were raised from the 90th day of pregnancy to the end of delivery, and the lambs were weaned at 60 days. Dietary protein levels had significant effects on blood urea nitrogen, glucose, ammonia nitrogen and triglyceride of ewes (p < 0.05). The height, chest depth, chest circumference, straight crown hip length and curved crown hip length of lambs decreased at first and then increased with the increase of protein. The body length, chest circumference, head width and head length of weaned lambs decreased at first and then increased with the increase of protein. The results showed that when the dietary protein level was increased to 12.4%, the amino acid, glucose and fat metabolism of ewes were affected. The body size development of lambs was better than 10.12% and 11.26% proteins.

日粮蛋白质对晚孕湖母羊及其子代生长性能及血清生化指标的影响

摘要

【摘要】:目的探讨妊娠晚期不同蛋白质水平对母羊和羔羊生长性能、血清生化指标的影响。33只母羊(初重46.4±1.38kg)随机分为3组,每组11只母羊。为提供满足 10.00 MJ/kg ME 需求饮食的成分而配制的三种饮食的蛋白质水平为:10.12%、11.26%、12.4%。母羊从妊娠90天饲养至分娩结束,羔羊60天断奶。日粮蛋白质水平对母羊血尿素氮、葡萄糖、氨氮和甘油三酯有显着影响(p < 0.05)。随着蛋白质的增加,羔羊的身高、胸深、胸围、直冠臀长和弯冠臀长先降低后升高。断奶羔羊的体长、胸围、头宽、头长随着蛋白质的增加呈先下降后上升的趋势。结果表明,当日粮蛋白质水平提高到12.4%时,母羊的氨基酸、葡萄糖和脂肪代谢受到影响。羔羊体型发育优于10.12%和11.26%蛋白质。
