摘要
用 72只 10 0日龄左右青年獭兔进行能量、粗蛋白等营养需要量试验 ,设高能量高蛋白 (第 1组 :DE 11 17MJ/kg ,CP18 44 % )、高能量中蛋白 (第 2组 :DE 10 98MJ/kg ,CP 16 2 9% )、低能量高蛋白 (第 3组 :DE 10 5 3MJ/kg ,CP 19 2 9% )和低能量中蛋白 (第 4组 :DE 10 2 6MJ/kg ,CP 16 0 5 % ) 4个组。 74天生长发育和被毛质量测定结果 :①饲喂消化能为10 98～ 11 17MJ/kg的饲料 ,有利于青年獭兔生长速度和饲料利用率的提高 ,也有利于屠宰率的改善。其中以消化能为11 17MJ/kg、粗蛋白 19 2 9%的饲料 ,其生长速度和饲料利用率最好。②饲喂消化能为 10 2 6～ 10 5 3MJ/kg、粗蛋白16 0 5 %～ 19 2 9%的饲料 ,有利于毛皮质量的提高。③综合本研究结果 :生产优质商品兔皮的青年兔饲喂含消化能为10 2 6～ 10 5 3MJ/kg、粗蛋白 16 0 5 %～ 19 2 9%的饲料为宜。
Present experiment was conducted to study energy and crude protein requirement of the young Rex rabbit and 72 young rabbits at the age about 100 day were applied in four groups. Group 1 was high energy and high protein (DE 11.17 MJ/kg,CP 18.44%),group 2 was high energy and medium protein (DE 10.98 MJ/kg,CP16.29%), group 3 was low energy and high protein (DE 10.53 MJ/kg,CP 19.29%), and group 4 was low energy and medium protein (DE 10.26 MJ/kg,CP 16.05%). The results of measurements for rabbit growth and coat quality showed that,①Diet of 10.98～11.17 MJ/kg was good for growth and improving feed utilization efficiency, and the diet of DE 11.17 MJ/kg and CP 19.29% had got the highest growth rate and feed efficiency. ②Diet of DE 10.26～10.53 MJ/kg and CP 18.44% for young rabbit was positive for fine quality coat.③it was concluded that diet of DE 10.26～10.53 MJ/kg and CP 16.05～19.29% was ideal for coat-purpose young Rex rabbits.
