Abstract

The live body weight of farm animals is a major factor in determining a number of traits that are significant economically. Birth weight, weaning weight, yearling weight, and the effectiveness of weight gains are growth parameters that are economically significant in relation to the cost of production. Data on body weight and zoometric characteristics were gathered over a 12-year period from the Sirohi goat AICRP project in Udaipur, India (2007 - 2019). The least-square means at birth to 12month of age of body height were 30.36 ± 0.288 cm to 64.00 ± 0.998 cm, body length 29.15 ± 0.321 cm to 58.89 ± 1.168 cm, body girth 30.46 ± 0.284 cm to 64.13 ± 0.995 cm, body weight 2.53 ± 0.034 kg to 22.38 ± 0.53 kg, respectively. At various stages of life, it was shown that there were positive, low to medium-level (0.258 to 0.762) phenotypic associations between body weight and zoometric features. The best fit regression equation was developed using a combination of body height, body length, and body girth at birth, 3, 6, and, 12 months age, based on the largest R² value (0.694). Result revealed that combination of body height, body length, and body girth required for best regression equation and this combination also positive association with zoometric traits.
