摘　　要：本试验目的是通过研究限饲和自由采食对庄河大骨鸡产蛋性能和增重的影响,确定较佳的产蛋期大骨鸡能量摄入量,为养殖生产奠定基础。将60只52周龄的庄河大骨鸡产蛋母鸡随机分成限饲组(130 g/(只·d))和自由采食组,每组3个重复,每个重复10只。试验结果表明,与限饲相比,自由采食大骨鸡的采食量、体重、蛋料比极显著增加(P<0.01),平均日采食量比限饲组增加了17.5%,产蛋率和蛋重变化不显著(P>0.05),但产蛋率有增加趋势。产蛋期大骨鸡代谢能摄入量较佳值为1.335 MJ/(只·d)。The objective of this research was determining preferred energy intake for Daguji laying hens by effect of restriction and free on Zhuanghe Daguji laying performance and bodyweight gain, and lied the foundation for its breeding. Fifty-two weeks-old 60 Zhuanghe Daguji laying hens divided into feed restriction group（130 g per day per hens） and free intake group randomly,each group 3 repeat and 10 hens. The result indicate that feed intake, body weight, and ratio of feed to egg extremely significant increased（P〈0.01）, and average daily feed intake was raised17.5% compared to restriction. Laying rete and egg weight had no significant change（P〉0.05）while had improved tendency. Preferred metabolizable energy intake was 1.335 MJ/hens per day for laying hens.
