Abstract

The study was conducted to compare body weight, egg, and carcass characteristics, as well as several biochemical parameters amongst three lines of plumage color of quails, including, black, white, and brown (n= 200 each). Body weight was analyzed on a weekly basis throughout the study period (third– 13th week of age). Eggs were collected for seven consecutive weeks of sexual maturity (seventh – 13th week of age). In addition to egg quality measurements, 16 serum biochemical parameters were also determined. The brown line had exerted significantly higher values of body weight in most analyzed weeks of sexual maturity. It had given higher values of albumen height and shell thickness, as well as carcass dressing than other lines. Simultaneously, a significantly high number of eggs in the white line were observed in the most analyzed weeks. Besides, it had given higher values in terms of shell and yolk weights, as well as several carcass characteristics, such as the heart, thigh, breast, and back. The biochemical analyses had shown no significant differences amongst the analyzed populations with exception of a higher concentration of amylase in the brown line. In conclusion, our study revealed the presence of a clear superiority of the brown and white lines in terms of the meat and egg productivity, respectively. Therefore, we recommend breeders to raise brown and white lines for a better production of meat and eggs, respectively, whereas the black line has shown the least productive characteristics than other two lines throughout the study period.
