Productive performance of purebred Thai native black-bone chickens (Chee Fah and Fah Luang) and their crossbreds

摘要

This study was conducted to compare productive performance between purebred Thai indigenous black-bone chickens and their reciprocal crossbreds. Four different genetic groups were studied: 2 purebreds (Chee Fah and Fah Luang) and 2 crossbreds (Chee Fah. Fah Luang and Fah Luang. Chee Fah). The results showed that Fah Luang. Chee Fah had the significantly highest body weight at birth and 20-week of age, while the lowest values were found in Chee Fah. Fah Luang (p<0.05). For feed conversion ratio, Fah Luang. Chee Fah had greater potential than purebreds and Chee Fah. Fah Luang (p<0.05). Additionally, Fah Luang. Chee Fah grew faster than the others (p<0.05). The productive performance of crossbred chickens was more favorable than purebreds. Considering crossbreds, Fah Luang. Chee Fah showed greater performance than Chee Fah. Fah Luang. Therefore, Fah Luang had more potential for using as a sire than Chee Fah.
