Abstract
The present study was designed to investigate the effect of feeding various levels (0, 2.5, 5.0, 7.5 and 10%) of gaur meal to replace soybean meal in the five dietary treatments in starter (0 -11 d.), grower (12 – 22 d.) and finisher1 (23-35 d.) diets then all broiler chicks fed on finisher2 diet (36- 42 d., 0.0% guar meal) on broiler performance, carcass characteristics and economical evaluation. A total of 180 one day old broiler chicks of Hubbard breed were used for the experiment with 6 chicks per replicate and 6 replicates per treatments. Results indicated that adding guar meal at inclusion rates of 5% to practical broiler diets as a replacement of soybean meal up to 35 days of age then feds 0.0% guar meal diet up to 42 days of age, would have a positive effect on the cost of production and the economical efficiency of broiler chicks, without any adverse effect on productive performance or carcass traits of the broilers comparable to the control (0% gaur meal). On the other hand, chicks fed on above 5% gaur meal diets showed significantly decreased values of productive performance and reduction of the calculated economical efficiency percentages.
