dc.description.abstract The factors affecting production, the influence of high environmental temperature and response of layers and broilers to evaporative cooling and layers to different stocking densities are reviewed. The comparative performance of layers under cooled and natural climate was investigated in the first experiment. This included feed consumption, sexual maturity, percentage egg production, efficiency of feed utilization, egg size and mortality rate. Results indicated that the cooled environment improved the production parameters, i.e. egg production, efficiency of feed utilization (kg of feed-kg of eggs) egg size sexua1 maturity and mortality rate. Stocking density of 4 birds/m2 showed a superior performance in feed intake, energy intake, egg production, efficiency of feed uti1ization (kg of feed-kg of eggs) and mortality rate than all other treatments. Although the higher stocking densities of 8 and 12 birds/m2 were inferior to 4 birds/m2, yet they were superior to the uncooled 4 birds/m2. In the second experiment when cooling was applied to broilers, their performance i.e., feed intake, growth rate, efficiency of feed utilization (kg of feed-kg of meat) dressing percentage, was investigated. The results indicated an improved response to cooling. en_US
