The effect of adding mulberry leaf flavonoids to feed on growth performance,muscle quality,and serum biochemical indicators of meat sheep

文章旨在探讨饲料中添加桑叶黄酮对肉羊生长性能、肌肉品质和血清生化指标的影响。试验将40只肉羊随机分为对照组和试验组,对照组饲喂基础日粮,试验日粮为基础日粮+100mg/kg桑叶黄酮,每组4个重复,每个重复5只。预饲期15d,正试期120d。结果表明,试验组肉羊终末体重、平均日采食量、平均日增重均显著大于对照组(P<0.05),料重比显著低于对照组(P<0.05),且两组羊具有相同的生长趋势。试验组肉羊屠宰率、GR值、眼肌面积、羊肉红度及血清HDL含量均显著高于对照组(P<0.05),羊肉剪切力、蒸煮损失率、失水率、黄度、亮度及血清GLU、TG、TC、LDL含量均显著小于对照组(P<0.05)。结论 :饲料中添加桑叶黄酮能显著提高肉羊的生长性能,改善肉品质,增强机体脂质代谢调控。

To explore the effects of adding mulberry leaf flavonoids to feed on the growth performance,muscle quality,and serum biochemical indicators of meat sheep.Forty healthy meat sheep were randomly divided into a control group and an experimental group.The control group was fed with a basic diet,while the experimental group was fed with a basic diet plus 100 mg/kg mulberry leaf flavonoids.Each group underwent four replicates,with five sheep in each replicate.The pre trial period is 15 days,and the main trial period is 120 days.The results showed that,the final weight,average daily feed intake,and average daily weight gain of the experimental group were significantly higher than those 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 two groups had the same growth trend.The slaughter rate,GR value,eye muscle area,meat redness,and serum HDL content of the experimental group were significantly higher than those of the control group(P<0.05).The shear strength,cooking loss rate,water loss rate,yellowing,brightness,and serum GLU,TG,TC,and LDL content of the lamb were significantly lower than those of the control group(P<0.05).Conclusion:Adding mulberry leaf flavonoids to feed can significantly improve the growth performance,meat quality,and enhance the regulation of lipid metabolism in meat sheep.
