Performance of indigenous chickens of North-Eastern region of India under different rearing systems

摘要

An experiment was conducted to study the productive and reproductive traits in indigenous chickens of North-Eastern region of India under intensive, semi-intensive and extensive rearing systems and to compare the economy of production. Significant (P=0.05) differences in body weights at different stages of growth, eviscerated and giblet yields, fat content of meat, age at sexual maturity (ASM) and hen housed egg production (HHEP) were observed under different rearing systems. No significant differences in fertility, hatchability and mortality were observed under different rearing systems. Rearing of indigenous chicken was found to be economical under extensive system.
