饲粮中添加金银花渣和茉莉花渣对隆林黑山羊生长性能、肌肉品质及营养成分的影响OA北大核心CSTPCD

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.
