초록

본 연구는 Spent Bleaching Clay(SBC)를 육계사료의 에너지 공급원으로 활용 가능성을 구명하기 위하여 실시하였다. 부화 직후의 120수의 병아리(한협 3호)를4처리 3반복, 반복당 10수(암수 각각 5수씩)를 Control(T1) 사료에 SBC를 $2.0\%(T2),\;4.0\%(T3)$ 및 $6.0\%(T4)$ 첨가한 4처리로 배치하였다. 시험사료 급여전 1주일은 시판사료를 급여하였다. 4주간의 시험 기간동안 증체중 및 사료 섭취량은 T3 및 T4 처리구에서 증가하는 경향이 인정되었다. 사료효율은 T3구에서 개선되는 경향이 인정되었다. 가슴살 및 다리살에서 치방산 조성을 사료의 처리에 따른 효과는 인정되지 않았다. 육계 초기 및 후기 사료 급여시 모두, 사료중의 건물, 조단백질 및 조지방 이용율은 T4 처리구가 다른 처리구에 비해서 유의하게 감소하였으며(p<0.05), 대사에너지가도 T4 처리구가 다른 3구에 비해서 유의하게 저하하였다(p<0.05). 사료중의 조회분의 이용율은 사료의 처리에 따른 차이는 인정되지 않았다. 결론적으로 본 시험의 결과 육계사료에 $2\~4\%$의 SBC첨가는 육계의 성장 및 사료효율 개선의 가능성이 있음이 사료된다.

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.
