Abstract
This study was conducted to evaluate the feasibility of spent bleaching clay(SBC) as an energy resource for meat type chicks. A total of one hundred twenty 1-d old broiler chicks(Han-hyop, No. 3) were divided into four groups and each group was assigned to one of the following diets: 0(T1), 2.0(T2), 4.0(T3) and $6.0\%$ SBC(T4). Each treatment had 3 replications of 10 birds. Before feeding experimental diets, they were fed a commercial diet for a week Body weight gain and feed intake tended to increase in T3 and T4, respectively. Feed efficiency(feed intake/ gain) tended to decrease in T3 compared to other groups. Fatty acid composition of breast and thigh meat was not significantly affected by feeding SBC. Utilization of dry matter, energy, crude protein and crude fat was lower in T4 than in the other groups during both starter and finisher periods(p<0.05). Crude ash utilization was not significantly affected by feeding dietary SBC. These results indicate that broiler diets may be supplemented with 2 to $4\%$ SBC without adverse effect on growth.
