摘　　要：该文旨在探究精料中用小麦替代玉米对西农萨能奶山羊羔羊生长发育和血清生化指标的影响。选取同质性较好的初生羔羊80只(公母羔各40只),按性别随机分4组,M1、M2为公羔组,F1、F2为母羔组,其中M1、F1组饲喂对照组精料配方1,M2、F2饲喂试验组精料配方2(小麦代替30%玉米)。每2周测定羔羊体重,每4周测定体尺指标并采集血样测定血清生化指标。结果发现:精料中用30%的小麦替代玉米对羔羊的平均日增重、体尺和血清生化指标无显著影响(P>0.05);性别影响羔羊的生长发育,公羔的平均日增重显著高于母羔(P<0.05);不同性别间的体尺和血清生化指标无差异(P>0.05)。综上所述,当小麦价格低时,在奶山羊羔羊中可用30%的小麦代替玉米,不会影响羔羊的正常生长发育,具有降低成本的潜力。This study aims to investigate the effects of replacing corn with wheat in the concentrate feed on the growth and development of Saanen dairy goat lambs and their serum biochemical indices.A total of 80 newborn lambs(40 males and 40 females)with good homogeneity were selected and randomly divided into four groups based on gender:M and M2 for male lambs,and F1 and F2 for female lambs.The M1 and F1 groups were fed the control concentrate feed formulation 1,while the M2 and F2 groups were fed the experimental concentrate feed formulation 2,which replaced 30% of the corn with wheat.The body weight of the lambs was measured every two weeks,while body measurements were taken every four weeks,and blood samples were collected for serum biochemical analysis.The results indicated that replacing 30% of corn with wheat in the concentrate feed did not significantly affect the average daily weight gain,body measurements,or serum biochemical indices of the lambs(P>0.05).However,the gender of the lambs influenced their growth and development,with male lambs exhibiting a higher average daily weight gain compared to female lambs(P<0.05).There were no significant differences in body measurements or serum biochemical indices between the different genders(P>0.05).In conclusion,when wheat prices are low,it is feasible to replace 30% of corn with wheat in the concentrate feed for dairy goat lambs,which will not affect their normal growth and development.And in the meantime,it can save the cost.
