摘要

生长是一个动态过程，它反映了遗传和环境反应导致的身体结构变化。本研究的目的是确定 BPPIB-TSP Bunikasih 的弗里斯兰荷斯坦雌性奶牛的生长曲线，并获得最佳曲线模型。研究对象为 0-18 月龄的本地和进口弗里斯兰荷斯坦奶牛。所使用的生长曲线模型包括贡珀兹（Gompertz）、对数（Logistic）、多项式（Polynomial）和MMF（Morgan Mercer Flodin）模型。得出的结果表明，不同生长曲线模型的精确度不同。本地 FH 奶牛的多项式模型的标准误差值为 2.1247，相关系数为 0.9997；而进口 FH 奶牛的多项式模型的标准误差值为 3.5368，相关系数为 0.9993。进口牛的生长模式快于本地牛：弗里斯兰-荷斯坦（FH）母牛生长曲线本地进口

POLA PERTUMBUHAN SAPI PERAH FRIESIAN HOLSTEIN BETINA DARI LAHIR SAMPAI UMUR KAWIN PERTAMA DI BPPIB-TSP BUNIKASIH

Growth is a dynamic process, which is a reflection of changes in body structure due to genetic and environmental responses. The purpose of this study was to determine the growth curve and obtain the best curve model for Friesian Holstein female dairy cows in BPPIB-TSP Bunikasih. The research used local and imported FH dairy cows aged 0-18 months. The growth curve models used are the models Gompertz, Logistic, Polynomial and MMF (Morgan Mercer Flodin). The results obtained show that the growth curve model has a different level of accuracy. Polynomial model for local FH dairy cows has a standard error value of 2.1247 and a correlation coefficient value of 0.9997, while for imported FH dairy cows it has a standard error value of 3.5368 and a correlation coefficient value of 0.9993. The growth pattern of imported cattle is faster than that of local cattle.Keyword : Friesian-Holstein (FH), Females, Growth Curve, Local, Imported
