Abstract

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.

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.
