为了研究银蓝色水貂、红眼白水貂、米黄色水貂的生长发育规律,试验利用Logistic和Gomp－ertz两种模型对体重数据进行拟合分析。结果表明:银蓝色水貂、红眼白水貂、米黄色水貂公貂初生重差异不显著(P>0.05);45日龄银蓝色水貂、红眼白水貂公貂的体重与米黄色水貂相比差异显著(P<0.05);90～150日龄银蓝色水貂公貂体重显著大于红眼白水貂和米黄色水貂(P<0.05),但红眼白水貂和米黄色水貂之间差异不显著(P>0.05)。银蓝色水貂、红眼白水貂、米黄色水貂母貂初生重差异不显著(P>0.05),45日龄银蓝色水貂、红眼白水貂母貂的体重与米黄色水貂相比差异显著(P<0.05),90～150日龄银蓝色水貂母貂体重显著大于红眼白水貂和米黄色水貂(P<0.05)。两种生长曲线模型对三个品种均能较好地拟合(R~2>0.99),其中Gompertz模型的拟合度效果最佳。
In order to study the growth and development of silver-blue mink, red-eye white mink and beige mink, the Logistic and Gomp-ertz models were used to fit the body weight data. The results showed that there was no significant difference in the birth weight of silver mink, red-eye white mink and beige mink (P> 0.05). The difference of body weight of 45-day silver-blue mink and red-eye white mink was more than that of beige mink (P <0.05). The body weights of male blue minks aged 90-150 days were significantly greater than that of red-eye white minks and beige minks (P <0.05), but there was no significant difference between red-eye white minks and beige minks (P> 0.05). The body weight of silver-blue mink, red-eye white mink and beige mink was not significantly different from that of beige mink (P> 0.05). The weight of 45-day silver-blue mink and red-eye white mink was significantly different from that of beige <0.05). The body weight of silver-blue minks aged 90-150 days was significantly greater than that of red-eye white minks and beige minks (P <0.05). The two growth curve models fitted well to all three cultivars (R ~ 2> 0.99), of which Gompertz model had the best fitting effect.
