Abstract:

Present study was carried out in Chhatrapur, Rambha, Khallikote and Jirabadi clusters of All India Coordinated Research Project on goat improvement in Ganjam district of Odisha from 2015 to 2017 to study the body weight and measurements of Ganjam goats, their correlations, and predictability of the body weight from body measurements. Data on body weight (kg), body length(cm), wither height(cm) and chest girth(cm) were recorded in adult Ganjam goats having one to four pairs of permanent incisor (PPI) teeth. Descriptive statistics and regression analyses were used. The mean body weight ranged from 22.5 kg to 30.6 kg, mean body length ranged from 63.0 to 69.6 cm, mean wither height ranged from 67.3 to 71.8 cm and mean chest girth ranged from 68.6 to 78.0 cm. All the correlations were found to be positive, moderate to high in magnitude and statistically significant (P<0.01). All the predictive models developed with each of the three body measurements were found to be statistically highly significant (P<0.01). The best-fitted regression equations were -23.68+0.29*BL+0.16*WH+ 0.25*CG for 1 PPI age group, the equation: -34.82 + 0.48 *BL + 0.42*CG for age group 2 PPI, the equation: -28.13+0.47*BL+0.33*CG for age group 3 PPI and the equation: -33.33+ 0.14*BL+0.18*WH+0.54*CG for 4 PPI age group. Chest girth was the dominant predictor variables among the three linear body measurements for all age groups except 1 PPI age group which had body length as the principal predictor.
