摘要: 用动态方法研究睾丸的成熟度,并以Gompertz模型建立了二花脸猪睾丸生长模型。通过估测,其拐点日龄、拐点重量、瞬时相对生长率、最大日增重参数分别为:79d、31.96g、0.022和0.70g。睾丸的拐点日龄和公猪的初情期接近。睾丸成熟度与初情期精液量呈显著正相关(P<0.05),但与精子的数量和畸形精子率无显著相关(P>0.05)。

Abstract: In the eassy, Gompertz model is utilized, and the growth pattern of the testis of Taihu boar (Erhualiang strain) is fitted. The day of growth inflection point, the weight of inflection point, instantaneous growth rate and maximum day gain are 79 days, 31.96g, 0.022 and 0.70g, respectively. The day of growth inflection point is puberty. The mature rate of testis has significant correlation with semen production(p<0.05).

Key words: TESTIS, GROWTH MODEL, PUBERTY, MATURE RATE, TAIHU
