Abstract
Various machine learning algorithms have been used to model and predict the body weight of rams of the Balochi sheepbreed of Pakistan. The traditional generalized linear model along with regression trees, support vector machine, and random forestsmethods have been used to develop models for the prediction of the body weight of animals. The independent variables (inputs) includethe body (body length, heart girth, withers height) and testicular (scrotal diameter, scrotal circumference, scrotal length, and testicularlength) measurements of 131 male sheep 2–36 months of age. The performance of the models is assessed based on evaluation criteriaof mean absolute error, mean absolute percentage error, correlation between observed and fitted values, coefficient of determination,and root mean squared error. A 10-fold cross-validation is done on a training dataset to check the stability of the models. A separatetraining dataset is used to assess the predictive performance of the developed models. The random forests model was found to providethe best results for both training and testing datasets. It was concluded that machine learning methods may provide better results thanthe traditional models and may help practitioners and researchers choose the best predictors for body weight of farm animals.
