摘 要:选择10日龄海兰褐商品蛋雏鸡,通过称重分群饲养,进行体重、均匀度、日耗量、死淘数和部分器官生长发育情况的测定。结果表明:称重分群饲养显著提高青年鸡的体重和均匀度,显著降低青年鸡的死淘率和耗料量,显著提高青年鸡部分器官的发育速度,增强其抵抗力。The 10-day-old Hy-line Brown commercial egg chicks were chosen in this experiment,and their body weight,uniformity,daily consumption,death rate and growth of some organs were also measured by weighing and group feeding.The results showed that the weight and uniformity of young chickens were significantly increased,the death rate and feed consumption of young chickens were greatly reduced,the growth speed of some organs of young chickens was clearly improved,and their resistance was enhanced.
