| 摘 要： | 通过测定张掖市甘州区甘浚镇120头西门塔尔杂交后备母牛的体高、胸围、体斜长和实际体重,发现后备母牛生长符合母牛育成期的生长规律,可以用公式来估测后备母牛的体重,用约翰逊公式和体重估测系数估测体重误差率均在5％以下。

| Abstract: | Relationships between body weight, wither height, heart girth, and body length were studied using data from a survey experiments with 120 observations in Simmental crossbred replacement heifers. The results showed that the growth of replacement heifers was in line with the growth law. Body weight can be estimated using the formula including heart girth and body length, the error rate of body weight form determination formula was below 5%. |
