Abstract
Aim:
To know the the relationship between body weight and
linear body measurements such as body length, height
at withers and heart girth in Malabari adult female
goats under field conditions.
Materials and
Methods: A total of 152 adult female Malabari
goats' body weight and body measurements (body
length, height at withers and heart girth) were used
to develop the step wise multiple regression
equations.
Results: The average body weight,
body length, height at withers and heart girth were
24.23 0.73 kg, 59.42 0.98 cm, 61.02 1.03 cm and
66.54 1.09 cm, respectively. Prediction of body
weight based on heart girth alone or combined with
other body measurements had higher coefficient of
determination (R2) and lower residual mean square (MSE).
Conclusion: It could be concluded that the
prediction model for body weight of Malabari female
adult goats with independent variable heart girth
can be better fit.
Key words: Body length,
Body measurements, Body weight, Heart girth, Height
