摘　　要：试验旨在研究代乳料对黔北麻羊早期羔羊生长性能、血清生化指标及经济效益的影响。选取体重相近、体况良好的25日龄左右的黔北麻羊断奶羔羊60只,随机分为4组,每组15个重复,每个重复1只羔羊。试验A组(对照组)自然哺乳,试验B组代乳料和母乳交替饲喂,试验C组在30日龄断奶饲喂代乳料,试验D组在40日龄断奶饲喂代乳料。预试期5 d,正式试验期60 d。结果显示:与对照组相比,试验D组显著提高羔羊日均增重(ADG)(P<0.05),显著降低料重比(F/G)(P<0.05)。试验D组的干物质(DM)、粗蛋白质(CP)和酸性洗涤纤维的表观消化率(ADF)均显著高于对照组(P<0.05)。试验D组羔羊的球蛋白(ALB)、钙离子(Ca^(2+))、生长激素(GH)的含量及碱性磷酸酶(ALP)的活性显著高于对照组(P<0.05)。试验D组羔羊利润最高,比对照组高出90.24元。研究表明,40日龄断奶饲喂代乳料可提高黔北麻羊羔羊生长性能,增强抗疾病风险,增加经济效益。The aim of this experiment was to study the effects of milk replacer on the growth performance,serum biochemical indexes,and economic benefits of lambs of Qianbei Ma Sheep.Sixty weaned lambs of 30-day-old Qianbei Ma sheep with similar body weight and good body condition were divided into four groups with 15 replicates per group and one lamb per replicate.Test group A(control group) was fed naturally,test group B was fed milk replacer and breast milk alternately,test group C was fed milk replacer at 30 days of age,and test group D was fed milk replacer at 40 days of age.The pre-test lasted for five days and the formal test lasted for 60 days.The results showed that compared with the control group,the average daily gain(ADG) of lambs in test group D was significantly increased(P<0.05),and the ratio of feed to gain(F/G) was significantly decreased(P<0.05).Meanwhile,the apparent digestibility of dry matter(DM),crude protein(CP),and acid detergent fiber(ADF) in test group D were significantly higher than that in control group(P<0.05).The concentrations of globulin(ALB) and calcium ion(Ca~(2+)),growth hormone(GH),and the activity of alkaline phosphatase(ALP) in test group D were significantly higher than those in control group(P<0.05).The profit of lambs in test group D was the highest,which was 90.24 yuan higher than that in control group.The study indicates that feeding milk replacer at 40 days of age can growth performance,enhance the risk of disease resistance and increase the economic benefits of Qianbei Ma Sheep.
