| 摘 要： | 用迪卡AB（迪）、S220（S）和罗曼AB（罗）公鸡分别与淮南麻黄（麻）母鸡杂交，以淮南麻黄鸡纯种作对照，组成4个组合，依次为迪麻、S麻、罗麻、麻黄。测定各组合产蛋性能，饲料转化比和蛋品质。结果表明，3个杂交组合中以罗麻组最好，其500日龄产蛋量为201.19个，总蛋重为10.988kg，分别比麻黄组高97.42%和111.31%，料蛋比为2.65:1，比麻黄组省料58.11%。因此，罗曼AB公鸡可作为淮南麻黄鸡杂种优势利用的父本。

| Abstract: | Cocks of Dekalb (D),S220 (S) and Lohmann (R) were crossed with Huainan SpottedBrown Yellow hens (H),yielding 4 combinations,namely,DH,SH,RH and HH with H purebred as control.The egg laying performance,feed conversion rate and egg quality of hens in different combinations were tested.The results showed that the egg laying performances and feed conversion rate of RH group was the best among 3 combinations and its egg production and total egg weight in 500day per hen were 20119 and 10988 kg respectively,much higher than those in HH group.Its feed conversion rate was 2651,and feed consumption 5811%,which were both lower than those in HH group. |
