Abstract

An experiment was conducted to study the use of industrial potassium chloride (PC) and ammonium chloride (AC) in grower male broiler diet as moderator of natural cyclic heat stress (23-41°C) in Qom province. Trial was carried out in random complete design with 12 treatments and 4 replicates in which 19 male broilers were reared on the litter. Experimental diets were as follows: Control group without any PC or AC, rations 2-5 contain 0.6, 0.7, 0.8 & 0.9 percent industrial PC, ration 6 contain 0.7 percent highly purified PC, rations 7-11 contain 0.3, 0.4, 0.5, 0.6 & ration 0.7 percent industrial AC and rations 12 contain 0.5 percent highly purified AC. Result indicated that rations contain 0.8 & 0.9 percent industrial PC observed highest feed intake and body weight gain that had no significant different with other treatment in exception with 0.6 percent PC (p<0/05). The best feed conversion ratio also were observed in rations contain 0.8 percent industrial PC that had no significant different with 0.7 and 0.9 percent industrial PC. There were no significant different in different part percentage of carcass and chemical component percentage of carcass. So increasing 0.8 and 0.9% PC in grower and finisher diets of heat stressed broilers were the best treatment in this trial
