波尔山羊杂交后代体尺、体重与肉用性能的相关性研究

Study on Correlation of Body Size?Body Weight and Meat Performance for Upgrading Offsprings of Boer Goat

本文利用 SPSS数据处理软件 (10 .0版 )统计分析了 2 3只 (约 8～ 9月龄 )波尔山羊与唐山奶山羊杂交后代公羊的体尺、体重和肉用性能。结果表明 :(1)波尔山羊与唐山奶山羊杂交 F1 代体尺、体重与肉用性能指标的变异程度大于 F2 代 ,其中宰前重、胴体重、净肉重和胸宽四项指标变异程度在 F1 和 F2 代中都很大 ;(2 )杂交 F1 代、F2 代各项指标 t检验结果 ,除胸宽外其余指标差异显著或极显著 ;(3 )波尔山羊杂交后代中胸宽与各项指标间相关不显著 ,宰前重、胴体重、净肉重与体尺指标相关显著或不显著。

Body size?body weight and meat performance was analysed using the program of SPSS10.0 for twenty three bucks of upgrading offspring to Boer goat and Tangshan milk goat. The result showed that the variability of F 2 is larger than that of F 1 on body size?body weight and meat performance, and the variability of slaughter weight?carcass weight? meat weight and chest wide for F 1 and F 2 were very larger; All index except chest wide between F 1 and F 2 was obviously difference; Correlation between every index and the chest wide was not significant difference; and correlation between slaughter weight? carcass weight ? meat weight and body size was significant difference.
