青年鸡与产蛋鸡易地专业化生产系统的研究

以1800只海兰雏鸡为试验材料,培育于青年鸡场;从130日龄起易地饲养于新安县某产蛋鸡饲养专业户,同时由青年鸡场一体的饲料厂供应源于同一套配方的配合饲料.结果表明,青年鸡与产蛋鸡易地专业化饲养切实可行.青年鸡亚系统,130日龄鸡的体重略高于标准,每只鸡的饲料成本为13.8元,盈利5.5元.产蛋鸡亚系统,91%以上的产蛋率维持12周,料蛋比2.7:1;90%以上的产蛋率期间,千只鸡的日盈利为141.8元.

Study on the Specialized Production of Pullets and Laying Hens in Different Places

Thirty - eight hundred Hyline chicks used as experimental birds were reared on a pullet farm, and from 130 days of age, transferred to be raised on a layer farm in Xinan County , Luoyang Prefecture, Henan Province. Compound feed was available from the same source. Re-sults showed that it was practicable to raise pullets and laying hens in different places. In the sub- system of pullets, body weight for 130 ?days - old birds was slightly higher than the standard, and feed cost per bird was 13. 8 yuan with a profit of 5. 5 yuan. In the sub - system of laying hens, 91 % or above egg production was maintained for 12 weeks with a feed to egg ratio of 2.7:1, and there was a daily profit of 141.8 yuan per thousand birds during the 90% or above egg production period .
