维生素 K3对五龙鹅生长性能、屠宰性能及养分表观利用率的影响
Effects of Vitamin K3 on Growth Performance, Slaughter Performance and Nutrient Apparent Availability of Wulong Geese
摘要
Abstract
This experiment was conducted to study the effects of dietary vitamin K3 supplemental level on growth performance, slaughter performance and nutrient apparent availability of Wulong geese. The experiment was divided into two stages, one stage was 1 to 4 weeks of age, and another stage was 5 to 16 weeks of age. In 1 to 4 weeks of age stage: three hundred and sixty one-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 the control group ( group Ⅰ) were fed a basal diet ( vitamin K3 content: 1. 23 mg/kg) , and geese in the other experimental groups (groups Ⅱ to Ⅵ) were fed the basal diets supplemented with 1, 2, 4, 8 and 16 mg/kg vitamin K3, respectively. In 5 to 16 weeks of age stage: three hundred and twenty four twenty-eight-day-old Wulong geese were selected and randomly divided into 6 groups with 6 replicates in each group and 9 geese in each replicate. Geese in the control group ( group A) were fed a basal diet ( vitamin K3 content:1.18 mg/kg) , and geese in the other experimental groups ( groups B to F) were fed the basal diets supplemented with 2, 4, 8, 16 and 32 mg/kg vitamin K3, respectively. The experiment lasted for 16 weeks. The results showed as follows: 1) according to the regression analysis, dietary supplemented with 4.81 mg/kg vitamin K3 at 1 to 4 weeks of age, the average daily gain was the highest;dietary supplemented with 11.59 mg/kg vitamin K3 at 5 to 16 weeks of age, the average daily gain was the highest. 2 ) Compared with the control group, in 1 to 4 weeks of age stage, dietary supplemented with 4 mg/kg vitamin K3 significantly increased percentage of half-eviscerated yield and percentage of abdominal fat of geese ( P<0.05 or P<0.01); in 5 to 16 weeks of age stage, dietary supplemented with 8 mg/kg vitamin K3 significantly increased dressing percentage, percentage of half-eviscera-ted yield, percentage of eviscerated yield and percentage of leg muscle (P<0.05 or P<0.01). 3) Compared with the control group, in 5 to 16 weeks of age stage, dietary supplemented with 8 mg/kg vitamin K3 signifi-cantly increased the calcium apparent availability ( P<0.01) , and significantly increased the apparent availabili-ty of dry matter, crude protein, ether extract, neutral detergent fiber, acid detergent fiber and phosphorus ( P<0.05) . In conclusion, under the conditions of this experiment, the appropriate dietary vitamin K3 supplemental levels of Wulong geese at 1 to 4 weeks of age and 5 to 16 weeks of age are 4.81 and 11.59 mg/kg, respective-ly.关键词
