초록

육계를 13주간 사육하면서 5주령부터 시험사료를 급여한 후 세포표면항원의 발현에 미치는 영향을 측정하기 위하여, 아마종실과 항산화제를 첨가하지 않은 대조구($T_{1}$ ), 아마종실만을 첨가한 사료($T_{2}$ ), 아마종실과 u-toco-pherol을 첨가한 사료($T_{3}$ ), 아마종실에 u-tocopherol과 셀레늄을 첨가한 사료($T_{4}$ )를 육계에 급여한 바 면역반응에 미치는 영향은 다음과 같았다. 1차 면역에 관여하는 monocyte 군은 시험사료의 급여기간이 증가할수록 $T_{1}$ 에 비하여 $T_{2}$ , $T_{3}$ , $T_{4}$ 구에서 유의적으로 증가하는 경향을 보였는데 그중 $T_{2}$ 구와 $T_{3}$ 구에서 많이 증가되었다. B세포는 시험사료의 급여기간보다는 급여사료에 따라 증가하였는데,$T_{2} , $T_{3}, $T_{4}$ 구는 $T_{1}$ 구에 비하여 2배 이상 증가하였다. CD4 양성반응(T helper cell)과 CD8 양성 세포(T $cytotoxic^pressor cell)는 $T_{2}$ , $T_{3}$ ,$T_{4}$ 구는 $T_{1}$ 구보다 증가하였으나 사료에 따라 일정한 차이는 없었다. MHC classII는 시험사료의 종류나 급여 기간에 따라 차이는 없었다.었다.

To examine the effects of feed additives on the expression of perpheral blood cell surface molecules, phagocytosis and antigen specific antibody formation, broilers were randomly assigned to $T_{1}$ , $T_{2}$ , $T_{3}$ , and $T_{4}$ groups. $T_{1}$ group was fed diet without any additives for 13 weeks, $T_{2}$ was fed diet with full fat flax, $T_{3}$ was fed diet with full fat flax containing $\alpha$-tocopherol, and $T_{4}$ was fed diet with full- fat flax containing $\alpha$-tocopherol and selenium. Since 5 weeks feeding the data were examined by flow cytometry using a panel of monoclonal antibodies. The expression of monocyte in all treated groups was significantly increased, in which the ratio of expression in $T_{3}$ group was especially evident. B cell expression of all treated groups was increased more than 2 fold. The expression of CD4+(helper T cell) cell and CD8+(cytotox$ic^pressor T cell) cell of all treated groups also was increased.ed.
