The circumstance of the feed conversion ratio of the broilers was surveyed to identify the problems of the case of nutritional condition of them in Neyriz district of the Fars Province Iran. Three broiler farms selected as the samples. Three growth stages rations; starter, grower, and finisher; were separately purchased.A ration also formulated as the control on the basis of the NRG standard tables as well as analysised results of corn, soybean, lucerne meal. and fish meal.The above control ration named A and exprimental rations were called B, G, and 0,respectively.396 broilers of Louhman breed were being fed with the mentioned rations in a randomized complete design with 4 treatments and 3 replications for eight weeks. Body weight gain, feed intake, feed conversion ratio, mortality, percentage, and one kg live weight increment expenditure as well as slaughtering in formation (dressing, leg breast muscle, and abdominal fat contents); of the 56 days old broilers were studied. The results showed a significant difference (PO.01) among the weight increment means of the 4 applied rations. The treatment B made the most and the treatment G had the least weight increment. Feed intake rates differ significantly (PO.01). The chickens that have been fed with ration G had the least consumption rate. There was not a significant difference in the feed conversion ratios at the end of the exprimental period. The other criteria; mortality percentage, dressing, difference were not significant between groups.
