摘要
试验旨在研究不同比例柞树叶对育肥辽宁绒山羊的饲喂效果.选择2岁左右、体重(48.57±1.98)kg的辽宁绒山羊32只,随机分为4组,每组4个重复(公、母各半),每个重复2只羊.对照组饲喂基础饲粮,试验1组、2组、3组分别饲喂含5％、10％和20％柞树叶的饲粮.预试期15 d,正式试验期45 d.结果显示:试验3组的平均日增重显著高于对照组(P＜0.05),料重比显著低于对照组(P＜0.05);试验3组的单位增重成本最低,每只羊比对照组每天多盈利1.15元;试验2组肌肉失水率显著低于对照组(P＜0.05).研究表明,柞树叶可以作为辽宁绒山羊育肥期的优质粗饲料,添加比例为20％效果较好.
Abstract
The experiment aimed to investigate the feeding effect of different proportions of oak leaves on fattening Liaoning cashmere goats.A total of 32 Liaoning cashmere goats aged about two years old,weighing(48.57±1.98)kg were randomly divided into four groups,with four replicates per group(half male and half female),and two goats per replicate.The control group was fed a basal diet,while the experimental groups 1,2,and 3 were fed diets containing 5％,10％,and 20％oak leaves,respectively.The preliminary trial period was 15 days,and the formal experimental period was 45 days.The results showed that the average daily weight gain of experimental group 3 was significantly higher than that of the control group(P＜0.05),and the feed to weight ratio was significantly lower than that of the control group(P＜0.05).The cost per unit weight gain of experimental group 3 was the lowest,with an additional profit of 1.15 yuan per goat per day compared to the control group.The muscle water loss rate of experimental group 2 was significantly lower than that of the control group(P＜0.05).The study indicates that oak leaves can serve as a high-quality roughage during the fattening period of Liaoning cashmere goats,and the effect is better when the addition ratio is 20％.
