为确定不同类型粗纤维饲料对肉鹅生长性能及屠宰性能的影响,试验选用160只四川白鹅仔鹅,随机分为4个处理,每个处理4个重复,每个重复10只(公母各占1/2)。对照组饲喂含花生秧粉20%的饲粮,试验组分别饲喂含苜蓿草粉10%、20%和30%的饲粮。结果显示:1)10%苜蓿草粉组平均日增重显著高于对照组(P<0.05),料重比显著低于对照组(P<0.05);2)10%、20%苜蓿草粉组屠宰率、全净膛率、半净膛率、胸肌率、腿肌率均显著高于对照组(P<0.05),腹脂率显著低于对照组(P<0.05)。结果表明:与对照组相比,四川白鹅采食含10%的苜蓿草粉饲粮表现出了较高的生产性能。
This experiment was conducted to determine the effects of different types of fibrous feeds on the growth and slaughter performance of Sichuan white geese. A total of 160 geese were randomly assigned to four treatments by sex (four replicates per treatment with ten geese per replicate). Four dietary treatments as control feed including 20% groundnut stem meal (C), control feed plus 10% alfalfa meal (T1), control feed plus 20% alfalfa meal (T2), and control feed plus 30% alfalfa meal (T3) were fed to the geese. The results showed as follows: 1) compared with the control group, the addition of 10% alfalfa meal significantly increased average daily gain of geese (P<0.05), and markedly decreased feed/gain ratio (P<0.05). 2) The addition of 10% and 20% alfalfa meal significantly increased dressing percentage, eviscerated ratio, semi-eviscerated ratio, breast muscle rate and leg muscle rate of geese (P<0.05), and markedly decreased abdominal fat rate (P<0.05), compared with the control group. These findings suggest that compared with the control, the addition of 10% alfalfa meal can improve the performance of Sichuan white geese.[Chinese Journal of Animal Nutrition, 2010,22(6):1752-1756]
