青绿甜高粱秸秆替代部分全价饲粮对鹅生长性能、屠宰性能及肉品质的影响
A Substitution Effect of Green Sweet Sorghum Stalks for Diet on the Growth Performance, Carcass Yields and Meat Quality in Geese
摘要
Abstract
This experiment was conducted to study the substitution effect of green sweet sorghum stalks for diet on the growth performance,carcass yields and meat quality in geese,and explore the feeding technology using green sweet sorghum stalks substituting diet.Three hundred and sixty 28-day-old Sichuan White geese (male and female in half) with an initial average body weight of (1.11±0.008) kg were randomly allocated into 6 treatments (control group,experimental group Ⅰ-Ⅴ) containing 6 replicates with 10 birds per pen.The birds in control group was provided the basal diet ad libitum without the green sweet sorghum stalks;the birds in group Ⅰ-Ⅴ were fed 96％,92％,88％,84％ and 80％ of basal diet fed in control group,respectively,and green sweet sorghum stalks were provided ad libitum.The experiment lasted until 70 days of age.The results showed that:1) The final body weight and average daily gain in control group was not significantly different from those in group Ⅰ and Ⅱ (P＞0.05),the average daily gain in control group and group Ⅰ were higher than those in group Ⅲ,Ⅳ and Ⅴ (P＜0.05).2) No significant difference was observed in dressing percentage,breast muscle percentage and leg muscle percentage among the 6 treatment groups (P＞0.05);compared with control group,abdominal fat percentage in group Ⅰ-Ⅴ and skin subcutaneous fat percentage in group Ⅰ,Ⅳ and Ⅴ were significantly decreased (P＜0.05),the gizzard index in group Ⅰ-Ⅴ was significantly higher than that in control group (P＜0.05).3) No significant difference was observed in the content of crude protein,intramuscular fat and inosine monophosphate in breast muscle among the 6 treatment groups (P＞0.05);the content of total amino acids,essential amino acids,delicious amino acids,saturated fatty acids and unsaturated fatty acids in the breast muscle in group Ⅰ-Ⅲ were not different from those in control group (P＞0.05).Collectively,it seems to be feasible to replace partial diet with green sweet sorghum stalks for geese,and 4％-8％ of diet can be replaced with green sweet sorghum stalks without negative effects on growth performance,carcass yields and meat quality in Sichuan White geese from 28 to 70 days of age.关键词
