【摘要】：本试验采用胚蛋注射技术研究孵化后期补充外源性营养物质蛋氨酸(Met)对朗德鹅生长性能和抗氧化性能的影响。选取300枚种蛋随机分为2组,每组3个重复,每个重复50枚种蛋。在孵化第24天进行Met注射,对照组不做任何处理,处理组注射Met营养液(Met 5 mg/m L,Na Cl 7.5 mg/m L)1.5 m L。出雏后,每个重复选取体重均匀、健康的雏鹅20只进行饲养试验,饲养28 d。结果表明:处理组对孵化率无显著影响(P0.10),但显著提高了朗德鹅初生重(P0.05),显著提高了0~7日龄平均日增重并显著降低了饲料增重比(P0.05);处理组降低了血清和肝脏中氧化型谷胱甘肽(GSSG)和丙二醛(MDA)含量(P0.05);提高了还原型谷胱甘肽(GSH)的含量和谷胱甘肽过氧化物酶(GSH-Px)酶活性以及GSH和GSSG的比值(P0.05)。试验结果显示,孵化后期给养Met可显著提高朗德鹅初生重,提高机体的抗氧化能力,促进了机体生长。
[Abstract]:The effects of supplementation of exogenous nutrient methionine (Met) on growth and antioxidant properties of Landes geese were studied by embryo egg injection technique. 300 eggs were randomly divided into 2 groups with 3 replicates in each group and 50 eggs per replica. On the 24th day of incubation, Met was injected into the control group without any treatment. The treatment group was injected with Met nutrient solution (Met 5 mg/m L, Na Cl 7.5 mg/m L) 1.5 mL. After brooding, 20 goslings with uniform weight and healthy weight were reared for 28 days. The results showed that the treatment group had no significant effect on hatching rate (P0.10), but significantly increased the birth weight of Landes geese (P0.05), significantly increased the average daily gain of 0-7 days old and significantly decreased the feed weight gain ratio (P0.05), while the treatment group decreased the oxidation in serum and liver. Glutathione (GSSG) and malondialdehyde (MDA) contents increased the content of reduced glutathione (GSH), glutathione peroxidase (GSH-Px) activity and the ratio of GSH to GSSG (P0.05). The results showed that feeding Met at the later stage of incubation could significantly increase the birth weight of Langde geese, improve the antioxidant capacity of the body, and promote the growth of the body.
