洞庭湖湿地虉草替代大白菜对肉兔生产性能的影响

Effect on productive performance of meat rabbit with Phalaris arundinacea replacing Chinese cabbage

试验采用48只青年期(40～45日龄、体重约800 g)发育良好、健康无病的新西兰肉兔,随机分为4组:1组饲喂基础日粮,2～4组分别用占日粮5%,15%和25%的虉草Phalaris arundinacea代替日粮中等量的大白菜,试验期35 d.试验结果表明:各组间兔的日增重、屠宰率、料肉比等指标差异均不显著(P＞0.05),可见虉草代替大白菜不影响兔的生长,以15%的替代量的3组增重效果最佳,经济效益最好.

In this thirty-five days experiment, 48 young and healthy New Zealand rabbits （40-45 days of age and about 800 g in body weight） were divided randomly into four groups. Basal diet was fed to the rabbits in group 1. In group 2,3,4, we used 5 %, 10 %, 15 % Phalaris arundinacea replacing basal diets-Chinese cabbage . Results were showed as follows： no significant difference （P〉0.05） in daily weight gain , feed conversion rate and dressing percentage. So we come to the conclusion that Phalaris arundinacea replacing Chinese cabbage has no effect on growth of meat rabbit. The weight gain and the economic benefits of group 3 is the best.
