摘要
本试验选用 4周龄固始肉鸡 972只 (公母各半 )。采用 3× 3因子设计 ,饲喂代谢能 (ME)和粗蛋白质 (CP)水平不同的 9种玉米—鱼粉—豆粕型日粮。通过饲养试验、比较屠宰试验和代谢试验 ,研究不同的能量和粗蛋白质水平对 5～ 8周龄的固始鸡雏鸡生产性能、屠体成分的影响 ,根据三个试验的研究结果 ,得出固始鸡在 5～ 8周龄阶段 ,其日粮适宜的能量和粗蛋白质营养水平分别为 :代谢能 12 .6 9MJ Kg,粗蛋白质 18.2 0 % ,蛋能比 14 .34g MJ。
In this experiment, 486 male and female chicks of 4 Week-old were selected respectively and reared separately. 3×3 factorial experiment was designed. Gushi chickens were fed with 9 diets which were corn fish meal soybean meal type under different metabolizable energy (ME) and crude protein (CP). The effects on the performances and carcass ingredients of 5 8 week old Gushi chickens under different ME and CP concentrations were studied by rearing , comparative slaughter and metabolism experiments. According to the results of three experiments , the optimal dietary ME and CP levels of Gushi chickens were found out:ME12.69MJ/Kg,CP18.20%,CP/ME14.34g/MJ.
