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.
