摘要

本试验通过在鹅饲粮中添加不同水平维生素B₆，探索1~4周龄鹅生长性能、屠宰性能及蛋白质代谢的影响，以确定维生素B₆的最适宜添加水平。选用1日龄五龙鹅360只，随机分为个6组，每个组6个重复，每个重复10只鹅。Ⅰ~Ⅵ组饲喂在玉米－豆粕型饲粮中分别添加0（对照）、2.5、5.0、10.0、20.0和40.0 mg/kg的维生素B₆的试验饲粮。试验期为4周。结果表明：1）饲粮添加维生素B₆能显著或者极显著提高1~4周龄鹅平均日增重（P0.05）；饲粮维生素B₆添加水平为6.16 mg/kg时平均日增重最大。2）与对照组相比，Ⅲ组显著提高了血清总蛋白、白蛋白和球蛋白含量（P<0.05）。3）肝脏中谷丙转氨酶、谷草转氨酶活性和总游离氨基酸含量与1~4周龄鹅生长性能均有显著相关性（P<0.05）。由此可知：1）饲粮维生素B₆对1~4周龄五龙鹅生长性能和屠宰性能有显著影响。2）饲粮中添加适量维生素B₆可提高鹅蛋白质代谢水平，鹅饲粮中维生素B₆适宜添加水平为6.16 mg/kg。

Abstract

This experiment was conducted to study the effects of vitamin B₆ on growth performance, slaughter performance and protein metabolism of Wulong geese, and to determine the optimal dietary level of vitamin B₆. Three hundred and sixty 1-day-old Wulong geese were selected and randomly divided into 6 groups with 6 replicates in each group and 10 geese in each replicate. Geese in groups Ⅰ to Ⅵ were fed the corn-soybean basal diets supplemented with 0, 2.5, 5.0, 10.0, 20.0 and 40.0 mg/kg vitamin B₆, respectively. The experiment lasted for 4 weeks. The results showed as follows: 1) vitamin B₆ significantly increased average daily gain of geese aged from 1 to 4 weeks (P0.05); when the dietary vitamin B₆ level was 6.16 mg/kg, the average daily gain reached the highest. 2) Compared with the control group,the contents of serum total protein, albumin and globulin in group Ⅲ was significantly increased (P<0.05). 3) The activities of alanine transaminase, aspartate transaminase and content of total free amino acids in liver had significant correlation with the growth performance (P<0.05). In conclusion: 1) vitamin B₆ has significant influence on growth performance and slaughter performance of Wulong geese aged from 1 to 4 weeks. 2) The optimal supplement level of vitamin B₆ can increased the protein metabolism level, and the recommended supplemental level of vitamin B₆ is 6.16 mg/kg.

Key words： VitaminB₆; geese; growth performance; slaughter performance; protein metabolism
