The present study was designed to investigate the effect of light source and type on growth performance, carcass traits and blood constitutes of Sharkasi chickens. Three hundred and sixty birds were randomly assigned to 6 groups and housed in floor pens under two light source and type from 4 wk till 24 wk of age. The first, second and third groups were reared under incandescent bulbs with continues light for 12 hours per day (C), 6 h continues light +6 h flash light/day (T1) and 12 hours flash light per day (T2), respectively. While the fourth, fifth and sixth groups were reared under fluorescent bulbs with continues light for 12 hours per day (T3), 6 h continues light +6 h flash light/day (T4) and 12 hours flash light per day (T5), respectively. Feed and water were available ad lib. and all the other conditions were the same during the experimental period. The results showed that light type significantly affected body weight, daily weight gain, feed conversion and carcass traits. However, it had insignificant effects on blood traits. In addition, birds reared under light source had significantly (P≤0.05) body weight, daily weight gain and feed conversion as compared to the other two groups. No significant differences (P≤0.05) were found between groups in leg problems and carcass traits. Finally, the economical efficiency of the birds reared under fluorescent bulbs was better than the incandescent light groups. However, the economical efficiency of the birds reared under flash light bulbs was better than the continues light groups.

This experiment was carried out using 720 Japanese quail eggs to study the hatch performance of different eggs as affected by lighting stimulation. All eggs were divided into six groups and incubated under the recommended conditions of the incubated quail eggs with lighting or without according to embryos age as follows: The first group (control, C) was incubated under dark conditions throughout whole incubation period, while, The second groups (T1) was incubated under light conditions during the 1st four days of incubation period. The third group (T2) was incubated under light conditions during the 2nd four days of incubation period. The fourth group (T3) was incubated under light conditions during the 3rd four days of incubation period. The fifth group (T4) was incubated under light conditions during the 4th four days of incubation period. The sixth group (T5) was incubated under light conditions throughout whole incubation period. The obtained results showed insignificant differences among light groups for chick weight and piped egg. However, significant differences in hatchability and hatch time, embryo growth had existed among lighting groups in different embryo age. It could be concluded the importance of embryo age under light effect, which could be use to minimize the light costs and maximize the hatching performance of Japanese quail eggs.

A total number of one hundred and twenty birds aged 4 weeks were randomly assigned into four equal groups to investigate the effect of feed form on growth performance, carcass characteristics, plumage conditions and economical efficiency of local turkey. The first, second and third treatment groups (T1, T2 and T3) were fed on pellets, crumbles and wet feed, respectively, and the forth group fed mash feed (T4) and considered as control group (C). The obtained results showed that treatments birds fed pellets and wet forms throughout the experimental period had superior body weight, feed conversation, body temperature and mortality percentages compared to birds fed mash and crumbles. Otherwise, no significant differences (P>0.05) existed in bon measurements, plumage conditions and carcass traits. It could be concluded that birds fed pellets and wet feed had high performance and economical efficiency. Consequently, diets for broiler chicks should be in pellets or wet form.
