桑叶黄酮对水牛泌乳性能、氨基酸代谢和血清生化指标的影响OA北大核心CSTPCD
Effects of mulberry leaf flavonoids on lactation performance,amino acid metabolism,and serum biochemical indexes of buffalo
试验旨在研究桑叶黄酮对泌乳水牛血清氨基酸代谢、血清生化指标和泌乳性能的影响.试验选取泌乳量接近的泌乳中期水牛20头,随机分为2组,每组10个重复,每个重复1头水牛.对照组饲喂基础饲粮,试验组饲喂基础饲粮+45 g/(头·d)桑叶黄酮.试验期5w.结果显示,饲喂桑叶黄酮能够显著降低血清低密度脂蛋白含量(P＜0.05),显著提高血清胰岛素含量(P＜0.05),显著降低血清蛋氨酸含量(P＜0.05),显著提高水牛泌乳量以及乳蛋白、乳脂肪含量(P＜0.05).研究表明,桑叶黄酮通过调控血清氨基酸和脂质代谢提高了水牛的泌乳性能.
The study aimed to investigate the effects of feeding mulberry leaf flavonoids on the serum amino acid metabolism,serum biochemical indexes,and lactation performance of lactating buffalo.Twenty buffalo with similar lactating yield were randomly divided into two groups with ten replicates in per group and one buffalo per replicate.The control group was fed with basic diet,while the experimental group was fed with basic diet+45 g/(head·d)mulberry leaves flavonoids.The experiment period was five weeks.The results showed that feeding mulberry leaves flavonoids significantly decreased serum low density lipoprotein(P＜0.05),significantly increased the serum insulin content(P＜0.05),significantly decreased the contents of methionine in serum(P＜0.05),and significantly increased the milk yield,milk protein content,and milk fat content(P＜0.05).The study indicates that the mulberry leaves flavonoids can improve the lactating performance of buffalo by regulating the metabolism of amino acids and lipids in serum.
