摘要
试验旨在探索金银花渣和茉莉花渣对隆林黑山羊生产性能和肉品质的影响.试验选择20只3月龄(断奶)、体重接近且健康的隆林黑山羊,随机分为试验组和对照组,每组10个重复,每个重复1只羊.对照组饲喂基础饲粮,试验组在基础饲粮中添加5％的金银花渣和茉莉花渣.试验期1年.结果显示:与对照组相比,试验组黑山羊的胴体重、净肉重、骨重以及春、夏、冬季的平均日增重显著增加(P＜0.05),体高、体长、胸围、末重、屠宰率及净肉率有增加的趋势(P＞0.05),肌肉pH值、熟肉率、多不饱和脂肪酸与n3多不饱和脂肪酸含量显升高(P＜0.05),肌肉导电系数、粗脂肪含量显著降低(P＜0.05).试验组肌肉粗蛋白含量、天门冬氨酸、苏氨酸、赖氨酸及鲜味氨基酸含量高于对照组(P＞0.05).研究表明,在饲料中添加金银花渣和茉莉花渣能够促进隆林黑山羊的生长发育,改善肉品质.
Abstract
The purpose of this experiment was to explore the effects of honeysuckle residue and jasmine residue on the growth performance and meat quality of Longlin black goats.Twenty 3-month-old(weaned)and healthy Longlin black goats were randomly divided into experimental group and control group,with 10 replicates in each group and one sheep in each replicate.The control group was fed with basic diet,while the experimental group was added with 5％honeysuckle residue and jasmine residue in the basic diet.The trial period was one year.The results showed that the carcass weight,net meat weight,bone weight,and average daily gain in spring,summer,and winter were significantly increased(P＜0.05),while the body height,body length,chest circumference,final weight,slaughter rate,and net meat rate were increased(P＞0.05).The muscle pH value,cooked meat percentage,polyunsaturated fatty acid,and n3 polyunsaturated fatty acid content increased(P＜0.05),and the muscle conductivity and crude fat content decreased(P＜0.05).The contentrations of crude protein,aspartate,threonine,lysine,and delicious amino acids in muscle of the experimental group were higher than those of the control group(P＞0.05).The study indicates that adding honeysuckle residue and jasmine residue to feed can promote the growth and development of Longlin black goats and improve the meat quality.
