| Abstract | ||
| This study was carried out at the poultry farm of animal resources of the College of Agriculture / University of Baghdad to compare two strains of japanese quail (Coturnix coturnix japonica) which were brown and white in production parameters during rearing period ( 1 - 6 weeks ) . A total of 75 day old chicks of each strains distributed into three replicates and reared at 2 m3 metallic cages .The data obtained revealed that brown quail significantly predominant in live body weight which were59.46 , 57.53 gm at 2 weeks of age , 122.53, 114.12 gm at 4 weeks of age and 171.15 , 167.11 gm at 6 weeks of age for brown and white quail respectively . Also brown quail significantly predominant in weight gain which were 63.07 , 56.59 gm during the first rearing period (period from 14 – 28 days) and 46.62 , 42.99 gm during the second rearing period (period from 29 – 42 days) , the average weight gain were 54.85 , 49.79 gm during the total rearing period for brown and white quail respectively , feed consumption were high in brown quail which were 152.6 , 138.8 gm during the first rearing period (period from 14 – 28 days) , 201.3 , 188.0 gm during the second rearing period (period from 29 – 42 days) , and the average feed consumption were 176.9 and 163.4 gm during the total rearing period ( 1 - 6 weeks ) for brown and white quail respectively . No significant differences between the two strains of japanese quail were appeared . feed consumption were high in brown quail compaired with white quail due to his high requirement of nutrients for high metabolic and growth rate , brown quail are fit for meat production and breeds crossing . | ||
