Short summary
The classification and regression tree (CART) method produced good models for predicting albumen weight, with R2 values of 0.94 and 0.96, and yolk weight, with R2 values of 0.93 and 0.92, in Potchefstroom Koekoek and Lohmann Brown layers, respectively. This study suggests that a CART data mining algorithm might assist in determining the breed standards of Lohmann Brown and Potchefstroom Koekoek chicken breeds.
