摘要
为研究不同能量水平对产蛋性能和蛋品质量的影响,试验选用504只194日龄罗曼粉蛋鸡,试验共设3个处理,每个处理5个重复,每个重复33～35只,分别饲喂三个能量水平(10.88、11.09、11.30 MJ/kg)的日粮。试验共进行30 d。试验结果表明,各处理组在采食量、产蛋率、平均蛋重、料蛋比、蛋壳强度和哈夫单位等方面差异不显著;表明能量水平在50～100 kcal/kg范围内波动,对蛋鸡生产性能和蛋品质量未产生显著影响。
The experiment was conducted to assess the effects of different levels of dietary metabolizable energy （10.88,11.09,11.30 MJ/kg）on laying performance and egg quality.A total of 504 194-day-old Lohmann pink-shell laying hens were randomly assigned to 3 treatments with 5 replicates each and from 33 to 35 hens in each replicate.The experi- ment lasted for 30 days.The results showed that there were no significant effects of ME levels observed on average daily feed intake ,laying rate, average egg weight ,feed conversion efficiency, eggshell strength and Hough Unit.It was indicated that decreasing 50-100 kcal/kg of the dietary ME had an overall negative effect on performance and egg quality.
