Abstract The present study was conducted on Beetal goat to study the suitability of five growth curve models and to estimate associated genetic parameters under most appropriate growth model using 1501 records of weights from birth to 12 months of age pertained to 60 males and 241 females for the period of year 2004 to 2019. Five growth models viz., Brody, Gompertz, Logistic, Bertalanffy, Negative exponential used and compared using goodness of fit criteria. Comparative analysis on the basis of goodness fit criteria revealed that Brody model was found to be most suitable model. The overall estimates of growth curve traits under viz., mature weight (A), inflexion point (B) and rate of maturation (k) under Brody model were 28.21 ± 0.9, 0.91 ± 0.01 and 0.13 ± 0.01, respectively. The least-square estimates showed that period of birth, sex, type of birth and weight of doe at kidding had significant (p

甜菜山羊生长曲线性状的生长曲线建模及遗传分析

摘要 本研究对 Beetal 山羊进行了研究，以研究五种生长曲线模型的适用性，并使用 60 只雄性和 241 只雌性的 1501 份从出生到 12 个月大的体重记录来估计最合适生长模型下的相关遗传参数。 2004 年至 2019 年期间。 使用五种增长模型，即 Brody、Gompertz、Logistic、Bertalanffy、负指数，并使用拟合优度标准进行比较。基于良好拟合标准的比较分析表明，发现 Brody 模型是最合适的模型。Brody模型下生长曲线性状的总体估计值分别为28.21±0.9、0.91±0.01和0.13±0.01，即成熟体重（A）、拐点（B）和成熟率（k）。最小二乘估计表明，出生时间、性别、
