EFFECT OF SOME MANAGEMENT SYSTEMS ON BROILER PERFORMANCE

Abstract

The current study was conducted in special poultry farm, Shibin El-Kom, Menoufia Governorate. The experiment was extended from Aril 2014 to May. 2015. The great object of this study was to determine the effect genotype (strains) and some environmental factors (such litters, feed forms and in additions ages effects) on production and economical efficiency of broiler production in Menoufia Government. One density was applied in open system, 10 birds/m2. All birds were reared on land with two litter types (sawdust and straw) with thickness 10 cm. The dormitories were 120m2. The total No. of birds were 1200 which were presented in farm, two strains, Cobb 500 (600 birds) and Ross 308 (600 birds) at two reared seasons. - The studied traits were as follow: Body weights at different ages, growth rates, feed consumption (FC) (kg per bird/cycle), feed conversion ratio FCR, mortality and uniformity. The results indicated that all traits were significantly affected by strains, Litters and feed forms and ages.
