为揭示商品特种野猪的生长规律，同时为其标准化生产及种质资源开发利用提供参考依据，以久仰香猪（♂）×纯种野猪（♀）杂交后代为父本，纯种野猪（♂）×苏太猪（♀）杂交后代为母本生产的商品特种野猪为研究对象，采用 Logistic、Gompertz 和 Von Bertalanffy 3种方程模型拟合其0～9月龄10个时期的生长曲线。结果表明：Logistic、Gompertz 和 Von Bertalanffy 3种模型均能很好拟合特种野猪的生长，拟合度（R 2）均高于0．99，结合卡方（χ2）适合性检验，其中 Gompertz 模型拟合最好（R 2＝0．999），拟合方程为y＝126．813e-4．351exp（-0．254t），Gompertz 模型拟合的商品特种野猪极限体重为126．813 kg，生长拐点为5．79月龄，拐点体重为46．65 kg。综合商品特种野猪的生长拟合曲线和体重变化规律认为，把特种野猪划分为0～3月龄、4～8月龄及9月龄至屠宰3个饲养阶段较理想。
為揭示商品特種野豬的生長規律，同時為其標準化生產及種質資源開髮利用提供參攷依據，以久仰香豬（♂）×純種野豬（♀）雜交後代為父本，純種野豬（♂）×囌太豬（♀）雜交後代為母本生產的商品特種野豬為研究對象，採用 Logistic、Gompertz 和 Von Bertalanffy 3種方程模型擬閤其0～9月齡10箇時期的生長麯線。結果錶明：Logistic、Gompertz 和 Von Bertalanffy 3種模型均能很好擬閤特種野豬的生長，擬閤度（R 2）均高于0．99，結閤卡方（χ2）適閤性檢驗，其中 Gompertz 模型擬閤最好（R 2＝0．999），擬閤方程為y＝126．813e-4．351exp（-0．254t），Gompertz 模型擬閤的商品特種野豬極限體重為126．813 kg，生長枴點為5．79月齡，枴點體重為46．65 kg。綜閤商品特種野豬的生長擬閤麯線和體重變化規律認為，把特種野豬劃分為0～3月齡、4～8月齡及9月齡至屠宰3箇飼養階段較理想。

To review the growth rule and provide a the reference basis for standardization breeding and development of genetic resources in the commercial strain wild boar,the growth curves were fitted by Logestic,Gompertz and Von Bertalanffy nonlinear growth models according to measured body weight values of the commercial strain wild boar in 0 ~ 9 months,which was from Jiuyang Xiang pig (♂)× purebred wild pig (♀ ) and Sutai pig (♀ )× purebred wild pig (♂ ) as the fathers and mothers respectively.All these models(Logistic,Gompertz and Von Bertalanffy)could fit the growth curves of stain wild boar well,and the fitting was higher than 0.99,the Chi-square test showed that the models of Gompertz had the best effect on fitting of growth curve for strain wild boar,the fitting equation was y =126.813e-4.351exp(-0.254 t),the biggest body weight was 126.81 kg,the inflection of growth and body weight were 5.79 months and 46.65 kg respectively,and three rational feeding stages of 0 ~ 3 months,4 ~ 8 months and 9 months to slaughter were divided according to the fitting of growth curves and the change regulation of body weight in the commercial strain wild boar.
