摘　　要：国内外畜牧工作者都十分重视利用雏鸡血液生化指标进行早期选种的研究。然而有关利用雏鸡血液生化指标综合选择指数对产蛋量进行早期选种的研究，在国内外均未见报道。为此，我们进行了蛋鸡早期选种血液生化指标多辅助性状综合选择指数的研究，制订出蛋鸡血液生化指标多辅...The early selection of one generation for Huainan Spotted Black Yellow chicken by synthetic selection index of multisecondary traits on blood biochemical indexes were conducted.The egg laying performances of hens early selection and direct selection (family selection)were tested.The results showed that the age at first laying,egg production and total egg weight at 300 days (300 EPD and 300 YEW) of hens for early selection were 180 79d,47 81 eggs and 2146 03g,respectively,hens for family selection were 196 81d,40 71 eggs and 1883 05g,respectively,differences were very significant(P<0 01)between them,The result showed that the egg laying performances of one generation of early selection were very significant higher than that of family selection.
