不同饲养方式对肉鸡生产性能的影响

选择1日龄罗斯308肉鸡12000只随机分为3组,在相同营养条件和饲养管理程序下,分别进行笼养、地面平养、棚架饲养,研究了3种饲养方式对肉鸡生产性能的影响。试验结果表明:49日龄时肉鸡体重笼养最高,其次是地面平养,棚架饲养最低,分别为2.6kg、2.5kg、2.4kg;肉鸡的料肉比笼养最低,其次是棚架笼养,地面平养最高;腿病的发生率笼养最高,其次是棚架饲养,地面平养最低;肉鸡出栏率笼养最高,其次是棚架饲养,地面平养的肉鸡出栏率最低。综上所述,笼养和棚架饲养与地面平养相比,能提高肉鸡增重和出栏率,降低料肉比。

Effect of Different Feeding System on Growth of Broilers

The present study were undertaken to determine the influence of different feeding system on growth of Ross 308 Broilers.12000 chickens 1～day～old of Broilers were randamLy devided into 3 groups and kept at the same nutrition conditions,then battery rearing,ground rearing and shelf rearing were carry out.Our results showed that The body weight of broilers were 2.6kg at battery rearing group which was the highest compared with ground rearing group 2.5kg and shelf rearing group 2.4kg respectively on 49～day～old.The feed conversion ratio(feed/gain ratio) was in the order of battery rearing group,shelf rearing group and ground rearing group.At the leg gets sick formation rate and the rate of market weight,battery rearing was highest followed in order by shelf rearing and ground rearing.Consequently,The body weight and the rate of market weight were increased and feed conversion ratio were decreased at battery rearing and shelf rearing compared with ground rearing.
