摘要

本试验旨在研究饲粮中添加维生素E和有机硒对攸县麻鸭产蛋性能、蛋品质、血清生化指标及咸蛋蛋黄品质的影响。选用200只健康的处于产蛋高峰期的攸县麻鸭,随机分为4个组,每组5个重复,每个重复10只鸭。对照组(Ⅰ组)饲喂基础饲粮,3个试验组(Ⅱ、Ⅲ、Ⅳ组)分别在基础饲粮中添加50 IU/kg维生素E、0.2 mg/kg硒、0.2 mg/kg硒+50 IU/kg维生素E。试验期为63 d。结果表明:1)Ⅱ、Ⅲ和Ⅳ组的产蛋率和日产蛋重均显著高于对照组(P<0.05)。Ⅱ、Ⅲ和Ⅳ组的料蛋比均显著低于对照组(P<0.05)。2)Ⅲ和Ⅳ组的蛋黄硒含量显著高于对照组(P<0.05)。Ⅱ和Ⅳ组的蛋黄维生素E含量显著高于对照组(P<0.05)。3)Ⅱ、Ⅲ和Ⅳ组的咸蛋蛋黄硬心率显著低于对照组(P<0.05),Ⅳ组硬心率显著低于Ⅱ和Ⅲ组(P<0.05)。4)Ⅱ、Ⅲ和Ⅳ组的血清中丙二醛(MDA)含量显著低于对照组(P<0.05)。Ⅱ、Ⅲ和Ⅳ组的血清中谷胱甘肽(GSH)含量和谷胱甘肽过氧化物酶(GSH-Px)活性均显著高于对照组(P<0.05)。由此可见,饲粮中添加维生素E、有机硒或二者联用能提高产蛋高峰期攸县麻鸭产蛋性能和抗氧化能力,饲粮中添加维生素E和有机硒在降低咸蛋加工产生的蛋黄硬心率方面存在协同增效作用。

Abstract

This experiment was conducted to study the effects of dietary vitamin E and organic selenium on laying performance, egg quality, serum biochemical parameters and salted egg yolk quality of Youxian partridge ducks. A total of 200 healthy Youxian partridge ducks during peak laying period were randomly divided into 4 groups with 5 replicates in each group and 10 ducks in each replicate. Ducks in the control group (group Ⅰ) were fed a basal diet, and those in three experimental groups (groups Ⅱ, Ⅲ and Ⅳ) were fed the basal diet supplemented with 50 IU/kg vitamin E, 0.2 mg/kg selenium and 0.2 mg/kg selenium+50 IU/kg vitamin E, respectively. The experiment lasted for 63 days. The results showed as follows:1) the laying rate and daily egg weight of groups Ⅱ, Ⅲ and Ⅳ were significantly higher than those of the control group (P<0.05). The feed/egg of groups Ⅱ, Ⅲ and Ⅳ was significantly lower than that of the control group (P<0.05). 2) The yolk selenium content of groups Ⅲ and Ⅳ was significantly higher than that of the control group (P<0.05). The yolk vitamin E content of groups Ⅱ and Ⅳ was significantly higher than that of the control group (P<0.05). 3) The yolk hard core ratio of salted eggs of groups Ⅱ, Ⅲ and Ⅳ was significantly lower than that of the control group (P<0.05), and the hard core ratio of group Ⅳ was significantly lower than that of groups Ⅱ and Ⅲ (P<0.05). 4) The serum malondialdehyde (MDA) content of groups Ⅱ, Ⅲ and Ⅳ was significantly lower than that of the control group (P<0.05). The serum glutathione (GSH) content and glutathione peroxidase (GSH-Px) activity of groups Ⅱ, Ⅲ and Ⅳ were significantly higher than those of the control group (P<0.05). In conclusion, dietary vitamin E, organic selenium or their combination can improve laying performance and antioxidant capacity of Youxian partridge ducks during peak laying peak period, and there is a synergistic effect of dietary vitamin E and organic selenium on reducing the yolk hard core ratio induced by salted egg processing.
