Classification Tree for Low Birth Weight Rate of Calves

Abstract

The aim of study was to determine effects and interactions of age of first insemination, first calving age, calving age, calving interval, lactation order, dry period, calving month and sex of calf variables on low birth weight rate in calves by using of Classification tree (CT) method. For this the observations obtained from 596 animal materials were used. As a result, calving interval, calving age and calving month were found as significant predictor variables for low birth weight rate of female calves. On the other hand, none of these (calving interval, calving age and calving month) variables was found as significant for male calves.
