摘　　要：试验旨在研究发酵草药精饲料对哺乳期羔羊生长性能及经济效益的影响。选取体重相近、健康新生羔羊50只,随机分为2组,每组25个重复,每个重复1只羊。对照组羔羊饲喂基础饲粮;试验组在基础饲粮中添加5%发酵草药。试验期62 d。结果表明,试验组羔羊末重、总增重、平均日增重均显著高于对照组(P<0.05);试验组羔羊精料总采食量、花生秧总采食量、全混合日粮(TMR)总采食量均高于对照组,且羔羊平均日采食量整体呈上升的趋势;试验组羔羊TMR/增重显著高于对照组(P<0.05),精料/增重、花生秧/增重、料重比与对照组相比差异不显著(P>0.05)。试验组总投入和增重收入均高于对照组。试验组每只羔羊较对照组的利润增加了354.9元。研究表明,羔羊哺乳期添加5%发酵草药,可明显提高羔羊哺乳期增重与经济效益。The experiment was to study the effect of fermented herbal concentrate feed on growth performance and economic benefits of lactating lambs.Fifty healthy newborn similar weight lambs were selected and randomly divided into two groups,with 25 replicates in each group and one lamb in each replicate.Lambs in control group were fed basal diet.The experimental group was fed the basal diet supplemented with 5%fermented herbal medicine.The experiment lasted for 62 d.The results showed that the final weight,total weight gain and average daily gain of lambs in experimental group were significantly higher than those in control group(P<0.05).The total feed intake of concentrate,total feed intake of peanut seedlings and total feed intake of TMR diet in experimental group were higher than those in the control group,and the average daily feed intake of lambs showed an overall upward trend.TMR/weight gain of lambs in experimental group was significantly higher than that in control group(P<0.05),but there was no significant difference in concentrate/weight gain,peanut seedling/weight gain and feed/gain ratio between experimental group and control group(P>0.05).Total input and income from weight gain were higher in experimental group than in control group.The profit of each lamb in the experimental group increased by 354.9 yuan compared with control group.The study indicates that adding 5%fermented herbs during lactation can significantly improve weight gain and economic benefits of lambs during lactation.
