摘要: 为探究新疆褐牛种公牛生长发育规律,利用SAS 8.1软件中的Logistic、Gompertz、Brody和Bertallanffy 4种常用的生长曲线模型对344头次新疆褐牛种公牛体重生长曲线进行拟合。结果表明,4种模型均能较好的拟合新疆褐牛种公牛体重生长,拟合度R2分别为 0.9217、0.9263、0.9176和0.9261,其中Gompertz模型对新疆褐牛种公牛体重生长发育的拟合效果较好,Logistic、Gompertz和Bertallanffy模型生长曲线的拐点分别为(0.4937岁、502.10 kg)、(1.3168岁、379.54 kg)和(1.0477岁、311.25 kg)。本研究对实际生产具有一定的参考价值。

Abstract: The aim of this study was to explore the principles for growth and development of Xinjiang Brown cattle, using this four common growth curve model named Logistic, Gompertz, Brody and Bertallanffy in the SAS 8.1 software to fitting the weight growth curve for 344 heads Xinjiang Brown cattles. The results showed that four kinds of model all could fit the weight growth of Xinjiang Brown cattle very well, the degree of fitting R2 was 0.9217, 0.9263, 0.9176 and 0.9261. The Gompertz model was the best to fitting the weight growth of Xinjiang Brown cattle. The inflection point of the growth curve of in model Logistic, Gompertz and Bertallanffy were (0.4937 year,502.10 kg),(1.3168 year,379.54 kg)and(1.0477 year,3115.25 kg),respectively. This study had the certain reference value to the actual production.
