This experiment was designed to determine the influence of various white light intensities on spermatogenesis, hematology and growth performance of male quail. A total of 80 birds of one day aged had been assigned to four equal groups: G1 control group was kept under natural light program 12h light:12h dark. G2, G3, G4 were exposed to artificial white light emitting diodes at 0.6, 45 and 25 Lux for 5 hours daily for 8 weeks starting at 14 days of age. The result showed that the application of Lux 0.6, 45 and 25 caused a significant increase in heart weight relative to control. Lux 0.6 led to decrease in total body weight, left testis weight and foam weight. The result revealed that exposure to 0.6 Lux caused significant decrease in sperm count and live sperm percentage and increase in dead sperm percentage. Program of 25 Lux generated a significant increase in RBC counts compared to 0.6 Lux. Exposure to 45 Lux and 25 Lux triggers a significant increase in PCV and hemoglobin concentrations. Exposures to 0.6 Lux and 25 Lux resulted in a significant increase in mean corpuscular hemoglobin concentration, while apply to program 0.6 Lux cause increase in stress index. The best feed conversion ratio was detected in normal daylight, 0.6 Lux and 25 Lux respectively. In conclusion, exposure of male quails to different intensities of white LED bulb had an effect on the some physiological and reproductive parameters.

This study was conducted to determine the effect of the heat stress on some blood parameters and role of probiotics (Poultrystar®) to reduce these effects, 120 common carp (Cyprinus carpio) with mean weight 150±10g were obtained from collage of Agriculture and forestry /University of Mosul. Fish were acclimated for at least 7 day in the laboratory and fed daily, the water temperature was maintained at 25 ±2°C. Three experiments have been done, each of 40 fish which have been divided randomly into four groups 10 for each. First experiment the four groups exposed to different water temperature (control 25, 30, 32, 34 °C), second experiment the four groups treated with (Poultrystar®) in a dose 1 g/ kg body weight by using stomach tube with exposed to heat stress (control 25, 30, 32 and 34 °C). In the third experiment the four groups have been treated with (Poultrystar®) in the same dose of the previous experiment for 7 days then exposed to heat stress. The results show there were significantly increase in hemoglobin concentration in three experiments, and also the Packed cell volume was significantly increase in three experiments, but the stress index was significantly decrease in three experiments, and the probiotics (Poultrystar®) improved the blood picture especially in the second and third experiment because no probiotic used in the first experiment.
