摘要
试验旨在研究日粮中不同能量水平对6~8月份白羽肉鸡生长性能的影响。试验选用白羽肉鸡576只,分3个阶段进行不同料型的饲喂,在第2、3阶段将试验鸡分为对照组和3个试验组,饲喂不同能量水平的日粮,试验期40 d。结果表明,在第2、3阶段试验中,在相同粗蛋白水平及限饲条件下,白羽肉鸡的平均体重增重及欧洲效益指数(EPI)均随饲料代谢能的增加而提高,料重比随代谢能的增加而降低。研究表明,白羽肉鸡全程使用高代谢能值的用料方案能够获得更好的生长性能和更优的经济效益。
The purpose of the experiment was to study the effect of various energy levels in diet on growth performance of white-feathered broilers from June to August.A total of 576 white feathered broilers were fed with diets of different types in three stages.In the second and the third stages,the broilers were divided into the control group and three experimental groups,and were fed with different energy levels respectively for a total of 40 experimental days.The results showed that the weight gain and EPI of white feathered broilers were improved with the increase of metabolizable energy,and the feed to gain ratio was decreased with the increase of metabolizable energy under the same crude protein level and feeding restriction conditions in the second and the third stage of experiment.The results indicate that better growth performance and greater economic benefit can be gained by implementing high metabolizable energy feeding scheme throughout the whole feeding process for white feathered broilers.
