The objective of this experiment was to investigate the effect of light flashes on the reproductive performance of New Zealand white rabbits. A total of sixty two rabbits aged 24 weeks were randomly distributed into three experimental groups (24 rabbit each). The rabbits in control group (C) were exposed to constant light (12 h Light: 12 h Dark). In the other treated two groups, the 12 h of daylight period was divided into 6 h (constant light) and 6 h (flashes of light) for either 15 min. / h (T1) or 30 min. / h (T2). Based on the results, significant (P≤0.05) effects were observed in conception rate and reproductive index of flashed light treated groups. Also, light flashes induced significant increases in rectal temperature, health risk and sperm-cell concentration. However, no significant differences were demonstrated in most semen traits, gestation period, litter size, bunny weight, blood parameters values and mortality rate. It concluded that the most suitable lighting program for reproductive performance of rabbits is the flashes of light (15 min/hour), because it was more economically efficient than continuous or flashes of light (30 min/hour).

The objective of the study was to evaluate the effect of feed form on Ross broiler chicks performance. A total ninety six chicks at one day old, divided into 4 treatment groups (24 birds/each), were housed in two-tier wire floor battery in a closed house. 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.
