摘要

本试验旨在评价饲喂木瓜叶粉(PLM)对断奶家兔生长性能和胴体特性的影响。45只断奶兔采用完全随机设计,采用5种饲粮处理,每个重复3次,每个重复3只兔。采用PLM的5个纳入水平(0%、5%、10%、15%、20% PLM)。实验动物被安置在金属笼子里,有单独的喂食器和饮水器。随机分配5种PLM试验饲粮。每周测定采食量和增重。研究结束时进行胴体评价。结果表明:各处理间采食量和料重比均无显著差异(P>0.05)。对照组(0% PLM)和10% PLM组的增重分别为960.33g和967.00g,高于5% PLM和15% PLM组(934.33g和932.50g)。饲粮添加至15%PLM时对胴体重有影响(p0.05)。由此可见,饲喂木瓜叶粉对家兔生产性能无不良影响。

Performance of weaner rabbits fed diets supplemented with Pawpaw (Carica Papaya) leaf meal
14 weeks feeding trial was conducted to evaluate the effect of feeding pawpaw leaf meal (PLM) on the growth performance and carcass characteristics of weaned rabbits. Fourty five (45) weaned rabbits were used in a completely randomized design with five dietary treatments, each replicated three time with three (3) rabbits per replicate. The five inclusion levels of PLM (0%, 5%, 10%, 15% 20% PLM) were used. Experimental animals were housed in metal hutches having separate feeders and drinkers. They were randomly assigned to the five experimental diets of PLM. Feed intake and weight gain were measured weekly. Carcass evaluation was conducted at the end of the study. The results showed that there was no significant difference (P>0.05) among all the treatments with respect to feed intake and feed-gain ratio. Weaner rabbits fed the control diet (0% PLM) and those fed 10% PLM recorded higher weight gains (960.33g and 967.00g respectively) than those fed 5% PLM and 15% PLM (934.33g and 932.50g respectively). Dressed weight was affected (P 0.05) by feeding up to 15%PLM. It is therefore concluded that feeding pawpaw leaf meal did not adversely affects the performance of rabbits.
