【摘要】 为促进肉鸡业的发展,挖掘蛋白质饲料资源以解决当今蛋白饲料不足,开展了该项研究。根据芝麻饼在日粮中的用量,试验设置1个对照组及5个试验组。试验鸡为AA鸡商品代,每组50只,分0—4、 5—8周前后两期。根据增重、饲料报酬、成活率、经济效益等指标综合评定试验结果。结果表明肉用仔鸡日粮中前期芝麻饼适用量为3.0—9.0％,最佳用量为3.0—6.0％;后期芝麻饼适用量为5.5—13.5％,最佳用量为5.5～13.5％;饲料报酬与经济效益得到明显的提高。更多还原

【Abstract】 The study has been carried out in order to exploit protein feed resources and promote the development of broiler feeding industry. The study has been designed with an control group and five experimental groups based on the additive quantity of sesame meal in the broiler ration . 6 diets were offered to 300AA broilers which were divided into 6 groups at random. The experiment was caried on in the two Periods of 0 - 4 and 5 - 8 weeks. The result which was evaluated according to the average weight, feed effiiency, survival Percentage and economic benefit shows that within 0 - 4 weeks the suitable additive quantity of sesame meal in the broiler ration is 3.0 - 9.0% and the optimum additive quantity is 3.0-6.0%,and within 5 - 8 weeks the suitable quantity is 5.5-17.5% anh the optimum quantity is 5.5-13.5%. Furthermore, the feed efficiency and economic benifit can be largely increased.更多还原
