摘要
本试验旨在研究饲料中粗纤维对实验兔生产性能影响的情况。试验设计了六种具有不同纤维水平的实验兔配合饲料 ,其中最高者为 2 1.2 % ,最低者仅为 9.1% ,每级相差在 2 .5 %～ 3.0 %左右。试验结果发现 :饲喂含粗纤维水平为 14.9%～ 16 .4%、粗蛋白水平为 17.9%～ 16 .5 %配合饲料的兔 ,表现出良好的日增重和饲料转化率。低纤维、高蛋白饲料和高纤维、低蛋白饲料饲喂实验兔结果或是伴随较高的腹泻死亡率或是生产性能不佳。研究表明 :饲料中粗纤维水平是影响兔机体健康和生产性能发挥的重要因素。作者同时发现 :在实际生产中 ,适当增加饲料中粗纤维的水平 ,可弥补饲料配方设计不平衡、管理不善。
WT5”BZ]This experiment intended to study the effect of crude fiber in the feed to the performance of laboratory rabbits.we designed six levels of different crude fiber in the ration formulation from 21.2% to 9.1%,the different from each stage was 2.5～3.0%.From this experiment,it was found that the rabbits which were fed with 14.9～16.4% crude fiber,17.9～16.5% crude protein had good expression in daily gain and feed efficiency.The rabbit which were fed both with low level of fiber,high level of protein and with high level of fiber,low level of protein led to either high diarrhea death rate or had performance.These results showed:the crude fiber level was one of the most important factors in the feed which could effect the healthy and performance of the rabbits. The another also found that in the course of rabbit production proper improvement of the crude fiber level could make up the economic loss which were caused by the unbalance of the ration formulation,bad management or bad hygiene conditions.
