Study of Ascite and Performance in Five Strians of Commercial Broiler

This study was carried out to test Ascite and performance in different commercial broilers strains of male and female broilers. In this trial was used 400 chickens from five strains that were allotted in randomized completely design with five treatments included Arbor Acrse, Arin, Lohman, Cobb500 and Ross308 and four replicates. Diets were based on corn and soy been meal and similar to their catalogs. In during of period dead chickens carcass Studied related on hypertrophy right ventricle of heart for recognizing Ascite. When the birds reached 45 days of age, were recorded. No significant differences were observed in the live weight and feed intake in 28 and 45 days. The feed convertion was significant. The best feed convertion belong to Lohman. production efficiency index was significant. The best production efficiency index belong to Cobb and Lohman. By end of period 7 percent of chicken died due to Ascite. Outbreak Ascite was significant different among five strains (P<0.05). The most dead chicken belong to respectively Arin and Arbor Acrse and the less belong to Ross and Lohman. Natural mortality was not seen among Strain.
