| 摘 要： | 将800只1日龄樱桃谷肉鸭随机分为5组,每组4个重复,每个重复40只.抗生素组在基础日粮中添加30 mg.kg-1杆菌肽锌和6 mg.kg-1硫酸粘杆菌素,空白对照组饲喂基础日粮,3%、6%、9%发酵豆粕组分别用3%、6%、9%发酵豆粕替代基础日粮中的普通豆粕,并将日粮营养水平调为一致,试验期42 d,研究日粮中添加发酵豆粕对樱桃谷肉鸭生产性能和屠宰性能的影响.结果表明:樱桃谷肉鸭的采食量以抗生素组最高,与空白对照组,3%、6%发酵豆粕组的差异显著(P<0.05),而试验各组与空白对照组的差异不显著(P>0.05);全期体增重以空白对照组最低,其他各组均比空白对照组显著提高(P<0.05);料重比以6%发酵豆粕组最低,与空白对照组的差异显著(P<0.05),其他各组间的差异均不显著(P>0.05);试验组的屠宰率、半净膛率、全净膛率与抗生素组和空白对照组的差异不显著(P>0.05);3%、6%发酵豆粕组的胸肌率显著高于空白对照组(P<0.05);腿肌率以9%发酵豆粕组最高,较空白对照组显著提高(P<0.05);各组每羽肉鸭所获经济效益均高于空白对照组(P<0.05).可见,日粮中添加6%发酵豆粕可显著降低樱桃谷肉鸭的料重比,提高体增重,增加胸肌率,提高经济效益.

| Abstract: | 800 1-day-old cherry valley ducks were randomly divided into five groups(4 replications per group,40 ducks per replication) to determine the effects of fermented soybean meal on growth performance and slaughter performance.Antibiotic group was fed with the basic diet supplemented with 30 mg·kg-1 zinc bacitracin and 6 mg·kg-1 colistinsulfate,the control group was fed with basic diet,the experimental groups were respectively fed with basic diet supplemented with 3%,6%,9% fermented soybean meal,and the nutrients of all groups were regulated to the same level.The experimental results showed that the average feed intake of antibiotic group was significantly higher than the control group,3%,6% fermented soybean meal group(P<0.05),but all the experimental groups were not significantly higher than control group(P>0.05).The average weight gain of the treatment groups and antibiotic group was significantly higher than control group(P<0.05).The feed conversion rates of 6% fermented soybean meal group were significantly lower than control group(P<0.05),and the groups except 6% fermented soybean meal group were not significant difference.The dressed carcass percentage,whole net carcass rate and half net carcass rate had no significant difference in every group(P>0.05).The percentage of breast muscle of 3%,6% fermented soybean meal group was significantly higher than control group(P<0.05),but the leg muscle of 9% fermented soybean meal group was significantly higher than control group(P<0.05).Economic benefits in other groups were dramatically increased when compared with the control group(P<0.05).It was concluded that 6% fermented soybean meal added with basic diet could significantly reduce the feed conversion rates of cherry valley duck,and significantly increase the weight gain and the percentage of breast muscle,and increase economic benefit. |
