Effect of light duration on productivity of japanese quail

The study was designed to find the effect of light duration on overall production of Japanese quails such as weight gain, feed consumption and egg production. Total one hundred and twenty Japanese quails were grouped into three and each group was intended forty birds. Group-A with a light duration of 12 hours, group-B has 16 hours and group-C was fixed for 20 hours of light duration. The experiment was designed for two months (60 days). Obtained data was statistically analyzed by using the significant difference. The useful and valuable output of this study was gain in a very low-priced and contracted experimental design that is imperative for the poultry farmers in respect of light significance. The results revealed that the final body weight of birds was higher in group-C (143.17±4.44gram) followed by group-B (136.12±3.91gram) and group-A (133.72±6.81gram). Similarly, feed intake shown increased in group-C (1358±278.77gram) followed by group-B (1092±218.68gram) and group-A (882±169.45gram). Moreover egg production percentage was recorded high (68.7±0.54) in group-C and Puberty time was recorded less in group-C where light duration was increased. Overall net profit was also seen markedly higher in group-C. In each group light duration was provided during 1-5 weeks was variable. Regarding the data on initial body weight (gram) in all experimental groups showed negligible variation. It is concluded that the prolong energy source (light) increase the productivity, reproducibility and economical performance of the Japanese quail.
