摘要: [目的] 研究凉山猪的生长发育规律,并拟合其生长曲线。[方法] 以275头圈养凉山猪从出生到250d的20个时间点的生长发育数据为基础,研究了其生长发育规律。[结果] 凉山猪的体重增长符合"S"型生长曲线,150~190日龄为快速增长期。出生后越早其相对生长强度越大,之后,随着日龄增加逐渐降低。利用3种非线性模型对其生长曲线进行拟合,都获得了较理想的拟合效果。其中,以Von Bertalanffy模型的拟合优度最高,拟合结果最接近真实情况。[结论] 在其拟合生长曲线中,凉山猪的拐点日龄为193.33d,拐点体重为62.61kg,最大日增重为429.69g。

Abstract: [Objective] The objective of this study was to study the growth development and fit the growth curve of the Liangshan pig.[Method] The growth development data of 20time points of 275 Liangshan pigs in captive from born to 250dwas collected to study its regularity growth development.[Results] The rapid growth period was centralized between 150dand 190d,and the growth of Liangshan pig was fitted the typical S-curve..The relative growth intensity was higher for younger pigs,then decreased gradually.Three non-linear models were utilized to fit the growth curve of Liangshan Pig.Though all the three models had good fitness,and Von Bertalanffy model played better for achieving the real observations.[Conclusion] According to the fitting growth curve,the growth turning point of Liangshan pig was 193.33dwithin the weight of 62.61 kg and the highest daily gain of 429.69g.

Key words: Liangshan pig, growth development, growth curve, non-linear model, fitting
