几种豆科决明属(Chamaecrista spp.)牧草喂兔效果研究

Study on effects of legume forage Chamaecrista spp. feeding rabbit

对4个豆科决明属牧草Chamaecrista rotundifolia cv.CPI34721(Wynn)、C.rotundifolia cv.CPI86134、C.nictitanscv.ATF2217、C.nictitans cv.ATF2219进行草粉替代精饲料饲喂肉兔效果试验。结果表明:各供试决明品系草粉替代10％精饲料饲喂家兔,兔只饲料报酬与全精料喂养(对照)比较差异不显著。各供试决明品系喂兔具有提高胴体品质与兔肉品质(氨基酸含量)作用。其中以圆叶决明CPI86134饲喂效果最佳,平均日增重高于对照13.63％,料肉比降低12.08％,可提高经济效益24.13％。

A feeding value experiment of 4 legume forage powder(Chamaecrista rotundifolia cv. CPI34721(Wynn) ,C. rotundifolia cv. CPI86134,C. nicti-tans cv. ATF2217,C. nictitans cv. ATF2219)instead of 10% extractive fodder on rabbit was conducted. The results showed that there was not significant difference on ratio of fodder and meat, among different treatments,all of the tested Chamaecrista accessions can improve rabbit meat quality such as ammonia acid. The best accession was Chamaecrista rotundifolia cv. CPI86134. Compared with control, it can increase daily gaining weight at 13. 63% , decrease the rate of fodder and meat product at 12.08% ,and increase the economical benefit at 24.13% .
