Abstract

Objective: This study analyzes interactions of body condition score (BCS) with other factors and the effect of BCS on estimates of genetic paremeters of conception rate (CR) in Japanese Black cows.

Methods: Factors affecting CR were analyzed through the linear mixed model, and genetic parameters of CR were estimated through the threshold animal model.

Results: The interactions between BCS and each season and the number of artificial inseminations (AI) was significant (p<0.05), but that between BCS and parity showed no significance for CR. High CR was observed with BCS 3 in autumn (0.56±0.01) and BCS 4 in summer (0.56±0.02). The highest CR with BCS 3 (0.56±0.02) and BCS 4 (0.55±0.01) was observed at first AI. With BCS 5, however, the highest CR (0.55±0.08) was observed at second AI.

Conclusion: The model with BCS was notably conducive to the estimation of genetic parameters because of a low deviance information criterion of heritability that, nevertheless, was slightly lower than the model without BCS.

日本黑牛体况评分与受孕率的关系。

目的:分析体况评分(BCS)与其他因素的相互作用，以及BCS对日本黑牛受孕率遗传参数估计的影响。方法:通过线性混合模型分析影响CR的因素，通过阈值动物模型估计CR的遗传参数。结果:BCS与各季节及人工授精次数的交互作用显著(p)结论:有BCS的模型遗传力偏差信息标准较低，显著有利于遗传参数的估计，但略低于无BCS的模型。
