摘要/Abstract

摘要： 为指导二郎山山地鸡品种选育,本试验选用SD02、SD03品系第2世代54个家系、2个批次的种蛋进行孵化试验,比较批次间、品系间和品系内家系间的种蛋孵化效果差异。结果显示,SD03的各家系入孵蛋数(47枚)显著高于SD02(40枚)(P<0.05),SD02各家系的健雏率(99.5%)显著高于SD03(98.4%)(P<0.05)。SD03的死精率和死胎率低于SD02,受精率、受精蛋孵化率高于SD02,但差异不显著(P>0.05)。第1批次的受精蛋孵化率和健雏率高于第2批次,死精率和死胎率低于第2批次(P<0.05)。试验表明孵化效果SD03优于SD02,第1批次好于第2批次;SD02品系内家系3、30和48与SD03品系内家系13和49的各孵化指标远低于相应的品系均值,家系选种时应避免选用上述家系种鸡。

Abstract: In order to provide the basic information for further breeding work in Erlang mountainous chickens, we hatched two hatches eggs from lines SD02 and SD03 and compared the incubation effects between hatches, lines and families. The results showed that average egg number of line SD03 was more than line SD02, however the percentage of healthy chick of line SD02 was higher than line SD03(P<0.05). Though the percentage of dead fertile egg and dead embryo of line SD03 was lower than line SD02, and the percentages of fertility and hatchability of fertile egg in SD03 was higher than in SD02, these differences were not significant(P>0.05). The percentage of healthy chick and hatchability of fertile egg in the first hatch was higher than in the second hatch while the percentage of dead fertile egg and dead embryo in the first hatch was lower than in the second hatch. Generally, incubation effects of SD03 were better than SD02 and its effect in the first hatch was better than the second hatch. Incubation effects of family 3, 30, and 48 in line SD02 and family 13 and 49 in line SD03 were far poorer than average values of their corresponding lines. So, females from these families should not be used as breeders to reproduce next generation.

Key words: Erlang mountainous chicken; line; incubation effect; family breeder selection
