摘要
试验旨在研究日粮中添加0.1%溶血大豆卵磷脂对广西三黄鸡血清生化指标和胴体品质的影响。选取8周龄广西三黄鸡40羽,随机分为2个处理,每个处理4个重复,处理1为基础日粮,处理2在基础日粮中添加0.1%溶血大豆卵磷脂。血清生化分析结果表明,添加溶血大豆卵磷脂能够显著降低鸡血清中总胆固醇含量(P<0.05),但对血清中谷草转氨酶、谷丙转氨酶、碱性磷酸酶、尿素氮、总蛋白、白蛋白、葡萄糖、甘油三酯等指标无显著影响(P>0.05)。屠宰分析结果表明,添加0.1%溶血大豆卵磷脂可显著降低腹脂率(P<0.05),提高胸肌中的干物质含量(P<0.05),同时还能够显著提高腿肌中粗脂肪的含量(P<0.05)。综上所述,溶血大豆卵磷脂能够显著降低肉鸡血清中总胆固醇含量,改善胴体品质。
The study was conducted to investigate the effect of supplemented 0.1% soybean lecithin in feed on serum biochemical parameters and carcass quality of GuangXi Color-feathered Chicken. Forty 8-weeks-old GuangXi Color-feathered Chickens were randomly divided into two groups, four replicates of each group and treated as follows： basal diet and basal diet with 0.1% soybean lecithin. The results of serum biochemical parameters showed that, the total serum cholesterol of supplementation soybean lecithin was significantly reduced（P〈0.05）, but the Glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, alkaline phosphatase, blood urea nitrogen, total protein, albumin, globulin, glucose, triacylglycerol was no significant difference（P〉0.05） in the same time, the results of carcass quality showed that： GuangXi Color-feathered Chicken＇s of whole net carcass rates and breast muscle percentages of suplementation soybean lecithin was significantly increased（P〈0.05）, the abdominal fat rates was significantly reduced（P〈0.05）. The contents of dry matter in breast muscle and the contents of fat in leg muscle was significantly increased（P〈0.05）. GuangXi Color-feathered Chicken＇s total serum cholesterol of supplementation soybean lecithin was significantly reduced and improved the carcass quality.
