초록

본 연구에서는 Ross 208 종의 broiler 31,800수를 대조구와 복합 효소제 첨가구로 나누어 5주간에 걸쳐 대조구는 옥수수-대두박을 기초로 한 시판 육계사료를 급여하고, 시험구는 ${\beta}-glucanase$를 강화한 복합 효소제를 0.3% 첨가 급여하여 생산성과 혈청성분과 육질에 미치는 영향을 조사하였다. 시험기간 동안의 각 시험구의 증체량 및 사료 효율, 생산지수, 육성율을 측정하였고 무작위로 각 시험구당 20수를 선발하여 혈청 콜레스테롤 및 glucose 농도를 측정하였다. 또 ND와 IBD 항원을 음용 투여한 브로일러의 ND와 IBD에 대한 항체역가를 조사하였으며, 육질검사로 도체의 pH 및 육색, 가열감량, 보수력, 전단력을 측정하였다. 사육시험 결과, 0.3% 복합 효소제 시험구가 대조구에 비해 평균체중 19%, 생산지수 6.8%, 사료효율 5.5%, 육성율 5%의 증가를 나타내었다. 복합 효소제 시험구는 대조구보다 혈청내 HDL-콜레스테롤 양을 증가시키고 glucose의 양을 감소시켰다. 육계 혈청 내 ND 및 IBD 항원에 대한 항체역가도 복합 효소제 시험구가 대조구보다 높았다. 육질검사에 있어서는 복합 효소제 시험구가 대조구보다 육색과 전단력은 차이가 없었으나 보수력(p<0.05)과 가열감량이 개선되는 결과를 나타내었다. 이상의 결과로부터 ${\beta}-glucanase$ 활성을 강화한 복합 효소제의 첨가 급여는, 육계의 생산성과 혈청성분과 면역기능과 육질을 개선시키는 효과가 있는 것으로 사료된다.
