The experiment was conducted on a total of 600 chickens, assigned into 2 experimental groups, each group consists of 100 chicks and the experiment was conducted in triples. The first group is treated by AP, the second is controled. The results showed that supplementation of AP continuously for the first 5 days and one day a week followed by 0.5 grs/1 liter of drinking water for crossed Ri chicken broilers had good effect on the criteria of survival rate, growth, feed conversion ratio, performance index, economic number, differences from non-supplementation were statistically significant, increasing income for broiler keeping farmers' up to 5.6%.
