Abstract
The experiment of the first part was carried out at the Poultry Research Farm, Department Poultry production, Faculty of Agriculture, Assiut University during the period from 10 March to 28 July, 2014. It aimed to investigate the impact of using the incandescent, florescent and saving light sources on growth performance, carcass traits, some blood constitutes, mortality rate, external and internal egg quality, egg production and the some reproductive traits in female and male Japanese quail in addition to the economical efficiency of the tested lighting sources.
The experiment lasted 140 days (56- days growth period and 84 days laying period). It included 126 one day old Japanese quail chicks were wing banded, individually weighed and classified into 3 equal groups (control, treatment 1 and treatment 2), each having three equal replicates. The first group was considered as the control, while the second and the third groups were the treatments.
The Chicks in the control group were exposed to light emitted from incandescent lamp- 60 watt, while those in the (T1) and (T2) were subjected to light from Fluorescent- 60 cm-40 watt lamp and saving lamp- 26 watt, respectively. The lamps were adjusted to produce light with intensity of 10 lux during the growing period and 20 lux till the end of the experiment.
The experimental birds were housed in battery cages with the dimensions of (75 cm length, 50 cm width and 45 cm height) and raised under adequate managerial and hygienic conditions.
The indoor temperature which amounted 34 C during the first week of age, was decreased weekly by 2°C. to reach 24 °C till the end of the experiment. The temperature and the relative humidity were estimated by using a thermohygrograph and the THI values were calculated and recorded allover the experiment.
Birds were fed ad libitum on a mash starter and pelleted rations during the growing and laying period, respectively. Feed and water were available all the time.
The achieved important results could be concluded as follow:
1. The body weight BW increased relatively in birds exposed to light from the saving lamp, while the increase was only significant in birds subjected from the incandescent lamp during the experiment.
2. The body weight decreased significantly in birds by using the Flu. Lamp.
3. The BWG increased significantly in birds exposed to light from the incandescent lamp, while the increase was only relative by using the saving lamps.
4. The light sources had no effect on the mortality rate during the experiment.
5. The dressing and the heart percentages improved relatively, while the improvement percentage in the liver was significant by using the saving and the incandescent compared to the fluorescent lamps.
6. The use of the saving lamp improved significantly and the glucose percentages, while the improvement was only relative in albumen and total protein as compared with the incandescent and Fluorescent lamps.
7. The age and BW at sexual maturity decreased significantly in birds exposed to light from the saving as compared with the incandescent and Fluorescent lamps.
8. The egg production female increased significantly by exposure to light from the saving as compared to incandescent and the Fluorescent lamps during the laying season.
9. The lighting costs decreased by 56.35% and 34.76% by using the saving and Fluorescent lamps than the incandescent during a 6-months experimental period.
Taking in consideration these advantages it could be concluded the use of saving lamps highly recommend for raising Japanese quail birds, especially by small farmers.
