Abstract

ABSTRACT
Relationship of 6 linear body measurements (body length, height at wither, rump
height, heart girth, sacral pelvic width and rump length) on body weight of 68 adult (2-5
years) female Assam Hill goat was investigated using path analysis. The phenotypic
correlations among body weight and linear body measurements were found to be positive.
The correlation of body weight was found to be highest with body length (0.86) followed by
heart girth (0.79). The strongest direct effect on body weight was found for heart girth (0.593)
followed by body length (0.536). Indirect effects of other linear measurements were either
through heart girth or body length. The optimum multiple regression equation for weight
estimation included body length, heart girth, sacral pelvic width and rump length with
coefficient of determination of 82.4 per cent. The results obtained in the present investigation
could be helpful in weight estimation, selection and breeding program of Assam Hill goat.
Key words : Assam Hill goat, body weight, linear body measurements, path analysis.
