Abstract: 【Objective】 The objective of this study was to understand the growth and development patterns differences between Holstein and Jersey cattle.【Method】 The study measured four body measurements,including withers height,hip height,body length,and chest girth of 96 Holstein and 225 Jersey cattle from two herds in Shanxi and Hebei provinces.Four nonlinear growth models,Logistic,Gompertz,Bertalanffy and Brody models,were used to fit growth curves for four body measurements,and the estimated values of the growth parameters A,B,and K were obtained from different growth models.The model with the largest coefficient of determination (R2) was selected as the best fitting model for each body measurements trait of the three test groups,Holstein cattle from Shanxi,Jersey cattle from Shanxi and Jersey cattle from Hebei.【Result】 The best fit model for the growth curves of body height (R2≥0.939) and neck height (R2≥0.886) of Holstein and Jersey cattle was Brody model.For body length (R2≥0.942),the Bertalanffy model and the Brody model were selected as the best fit models for Holstein and Jersey cattle,respectively.The superiority of the Brody,Bertalanffy,and Logistic models was identified for growth curve modeling of chest girth (R2≥0.930) for Holstein cattle from Shanxi,Jersey cattle from Shanxi and Jersey cattle from Hebei,respectively.At the same age,the estimated values of each body measurement for Holstein cattle from Shanxi were higher than those of Jersey cattle from Shanxi,with the differences between two breeds gradually increasing with age.The estimated value for mature withers height was 155.8 cm for Holstein cattle and 123.9 cm for Jersey cattle,mature hip height was 161.2 cm for Holstein cattle and 133.1 cm for Jersey cattle,mature body length was 168.6 cm for Holstein cattle and 147.1 cm for Jersey cattle,and mature chest girth was 210.9 cm for Holstein cattle and 186.3 cm for Jersey cattle.【Conclusion】 Holstein and Jersey cattle had different growth patterns,which provide a better understanding of growth and development in Holstein and Jersey cattle and contribute valuable insights for feeding management.
