Classification and Regression Tree (CRT) Analysis to Predict Body Weight of Potchefstroom Koekoek Laying Hens

Abstract

P otchefstroom Koekoek chicken genotype was devel- oped from crossbreeding three chicken genotypes namely White Leghorn, Black Australorp and Bared Plymouth Rock (Tyasi et al., 2019; Mutibvu et al., 2019). This chicken genotype has gender-specific feather colour and patterns, which make it easy for sexing of day-old chicks (Heit, 2017). According to Dessie and Gatachew (2016), this chicken genotype is well acclimatized to the tropical regions which enable it to thrive in many of hot environment of the African countries, and is suitable for free-range production system and can also thrive and perform highly in small-scale rearing system.
