Estimation of body weight from different body measurements in Sirohi goat kids
Ganesh Ram Jat and Dr. Mahesh Datt
Data were collected on 40 Sirohi goat kids (20 males and 20 females) of different age groups maintained at RKVY Goat unit, SKN College of Agriculture, Jobner (Rajasthan). The animals were divided into three age groups as 0, 1, 2 and 3 months. To predict the body weight of Sirohi goat kids four body measurements (height at wither, heart girth, body length and paunch girth) were recorded on each animal. Body measurements varied with increasing age of animals. In goat kids, the highest correlation (r) was observed between body weight and heart girth at 0 (r =0.695) and 1 (r =0.756) months of age. Similarly height at wither at 2 month (r=0.824) and paunch girth at 3 month (r=0.837) of age. These correlations between body weight and body measurements were positive and significant (P<
0.01). The regression analysis indicated that live weight and body measurements (height at wither, heart girth, body length and paunch girth). Multiple regression analyses were used to calculate the prediction equations. The coefficient of determination (R2
) for weight estimation were for height at wither and paunch girth (86.0%) at 3 month. It was concluded that body weight of goat kids can be estimated in field using body measurements taken with a tape in the absence of weighing scales.
