Abstract

In rural areas where weighing scales are not easily accessible in the farms to monitor cattle performance, live weight is often predicted by using less accurate visual approaches which is highly subjective. This research was conducted to provide an easy method to estimate life weight using body measurements data for two cattle breeds: Simmental-Ongole crossed and Limousine-Ongole crossed (locally named, SimPO and LimPO). The data were collected from cattle owned by butches with 85 possession of slaughter cattle (> 250 kg of live weight). The measured variables including body length, chest depth, chest width, chest circumference, abdominal circumference, height at withers, height at sacrum, hip height, head index, head length, and head width. Data was analysed using simple and multiple linear regression. The results showed that head index was not significantly different between two breeds. The correlation results showed that body length and head index were not significant (P<0.05). Overall results of the Quadratic Method showed that abdominal circumference explained most variance on body weight; which R² value was the largest (0.657) and the root of mean squared error (RMSE) value was the lowest (41.313). The R² value in multiple linear regression is within the interval of 0.611-0.9. We conclude that the prediction for the models were relatively weak, this can be seen from the RMSE value of all models which were in the interval of 20.37-43.67 kg.
