摘要

本试验旨在研究饲粮维生素B5添加水平对产蛋期(34~44周龄)种鹅繁殖性能、蛋品质及血清生化和抗氧化指标的影响,以确定产蛋期种鹅对维生素B5的需要量。试验选用180只健康、体重相近的34周龄五龙鹅种鹅,随机分为6组,每组6个重复,每个重复5只鹅(1公4母)。Ⅰ~Ⅵ组的种鹅分别饲喂维生素B5添加水平为0、5、10、15、20和25 mg/kg的试验饲粮。预试期2周,正试期10周。结果表明:1)Ⅰ组种鹅蛋的合格率、受精率和孵化率均显著或极显著低于其余各组(P<0.05或P<0.01),Ⅴ组健雏率显著或极显著高于Ⅰ、Ⅱ和Ⅲ组(P<0.05或P<0.01)。2)Ⅴ组的蛋壳强度显著高于Ⅰ、Ⅳ、Ⅵ组(P<0.05)。3)Ⅳ、Ⅴ组的血清总蛋白含量显著或极显著高于Ⅰ、Ⅱ、Ⅲ、Ⅵ组(P<0.05或P<0.01),Ⅳ、Ⅴ组的血清白蛋白含量极显著高于Ⅰ、Ⅲ组(P<0.05)。4)Ⅲ、Ⅳ组的血清总抗氧化能力显著或极显著高于Ⅰ、Ⅱ和Ⅵ组(P<0.05或P<0.01),Ⅰ组的血清丙二醛含量显著高于Ⅲ、Ⅳ、Ⅴ和Ⅵ组(P<0.05),Ⅳ、Ⅴ组的血清总超氧化物歧化酶活性显著高于Ⅰ、Ⅵ组(P<0.05)。综上所述,饲粮中添加维生素B5有利于提高产蛋期种鹅的繁殖性能、蛋品质和抗氧化能力。本试验条件下,产蛋期种鹅饲粮维生素B5适宜添加水平为15~20 mg/kg。

Abstract

The aim of this study was to investigate the effects of dietary vitamin B5 supplemental level on reproductive performance, egg quality and serum biochemical and antioxidant indices of breeding geese during laying period (34 to 44 weeks of age), and to determine the requirement of vitamin B5 for breeding geese during laying period. A total of 180 healthy 34 weeks of age Wulong breeding geese were selected and randomly divided into 6 groups with 6 replicates per group and 5 geese per replicate (1 male and 4 females). The breeding geese in groups Ⅰ to Ⅵ were fed experimental diets which vitamin B5 supplemental levels were 0, 5, 10, 15, 20 and 25 mg/kg, respectively. The pre-experimental period lasted for 2 weeks, and the experimental period lasted for 10 weeks. The results showed as follows:1) the qualified rate, fertilization rate and hatching rate of breeding geese eggs of group Ⅰ were significantly lower than those of other groups (P<0.05 or P<0.01), and the healthy chicks rate of group Ⅴ was significantly higher than that of groups Ⅰ, Ⅱ and Ⅲ (P<0.05 or P<0.01). 2) The eggshell strength of group Ⅴ was significantly higher than that of groups Ⅰ, Ⅳ and Ⅵ (P<0.05). 3) The serum total protein content of groups Ⅳ and Ⅴ was significantly higher than that of groups Ⅰ, Ⅱ, Ⅲ and Ⅵ (P<0.05 or P<0.01), and the serum albumin content of groups Ⅳ and Ⅴ was significantly higher than that of groups Ⅰ and Ⅲ (P<0.05). 4) The serum total antioxidant capacity of groups Ⅲ and Ⅳ was significantly higher than that of groups Ⅰ, Ⅱ and Ⅵ (P<0.05 or P<0.01), the serum malondialdehyde content of group Ⅰ was significantly higher than that of groups Ⅲ, Ⅳ, Ⅴ and Ⅵ (P<0.05), and the serum total superoxide dismutase activity of groups Ⅳ and Ⅴ was significantly higher than that of groups Ⅰand Ⅵ (P<0.05). In conclusion, dietary addition of vitamin B5 is beneficial for improving reproductive performance, egg quality and antioxidant capacity of breeding geese during laying period. In this experiment, dietary vitamin B5 suitable supplemental level for breeding geese during laying period is 15 to 20 mg/kg.
