Genetic Polymorphism in Prolactin Gene and its Association with Reproductive Traits in Japanese Quail (Coturnix japonica)

The present  study  was carried out to investigate the polymorphism of intron 3 to exon 3 of prolactin gene containing 24 bpindel at nucleotide position (np)  358 and its association with some reproductive traits in Japanese quail. These traits consisted of weight (WSM) and age at sexual maturity (ASM), mean egg weight at 2nd, 4th, 6th, and 2-6th weeks (MEW), and the number of eggs during the 2...

Effect of Self-photoperiod on Live Weight, Carcass and Growth Traits in Quails (Coturnix Coturnix Japonica)

The weekly liveweight gain, growing and stress parameters of quails bred using two different types of lighting for 6 weeks following hatching were examined in this study. The first type of lighting was 23 L:1 D, continuous lighting (CL), widely used in the commercial system and the second was a self-photoperiod (SP) system consisting of a continuously lit chamber and a dark chamber the quails c...

Fearfulness and performance related traits in selected lines of Japanese quail (Coturnix japonica).

Fearfulness and economic traits were studied in three lines of Japanese quail. Two of the lines were of the same genetic origin and were subjected to divergent selection for the duration of tonic immobility (TI), a measure of fearfulness. Birds were selected for long (LTI) or short (STI) duration of TI. The third line (DD) was of a different genetic origin and had been selected for early egg pr...
