PERFORMANCE AND ECONOMIC IMPACT EVALUATIONS OF BROILER CHICKENS FOR DIFFERENT HOUSING SYSTEMS IN CLOSED FARMS
: The current study was conducted in private farms at AL-Khatatpa - the Menoufia Governorate, Egypt. Total number was 1155000 birds which used, all of them from one strain Ross 408 to investigate the effect of different housing systems (cages and floor) on broiler performance and evaluate that economically. By studying its effect on body weights at different ages, growth rates, feed index, feed conversion, European production efficiency (EPE), production number (PN) and livability. Where Body weights were measured at one-day-old chicks, then were weighted weekly till 35 days, and growth rates were estimated intervals at (1-7, 7-14, 14-21, 21-28, and 28-35) days of age, and cumulatively at ( 1-14, 1-21, 1-28, and 1-35) days of age.
