摘要
选择初始重(16.26±O.78)kg的6周龄断奶仔猪20头,采用完全随机试验设计,将20头仔猪分为5个处理组,饲喂不同塞里维辛酵母和粗纤维素含量的日粮,探讨其对猪生长、进食量和饲料转化率的影响。结果表明:仔猪每周增重和饲料转化率各处理问无显著差异,而每周平均进食量差异显著,饲喂由0.3%酵母、17.5%木薯皮和17.5%棕榈核饼组成的日粮,可促进仔猪生长和改善仔猪进食量。
In a feeding trial experiment with twenty 6-week-old growing pigs of initial live weight (16. 26±0. 78) kg at weaning, the inclusion of Saccharomyces cerevisiae and dietary fibre sources in the diets of pigs was examined. Five dietary treatments were formulated with four animals per treatment in a completely randomised design. The productive performance of the animals measured included growth rate, feed intake and efficiency of feed conversion. One-way analysis of variance was used to analysed the data and results revealed that both the weekly body weight gains of animals and feed conversion ratio showed no significant difference (P>0. 05) among treatment groups. However, the average weekly feed intake was significant (P<0. 05). It was concluded that the inclusion of 0. 3% yeast with 17. 5% of both cassava peel meal and palm kernel cake tended to improve growth rate and feed intake of pigs.
