Anti-Salmonella gallinarum Immunoglobulin 생산을 위한 계란의 이용 = Effect of Charcoal on the Production of Anti-Salmonella gallinarum IgY

국문 초록 (Abstract)

주요 가금티푸스 유발균인 Salmonella gallinarum에 대항하는 항체를 계란으로부터 효율적으로 얻기 위하여 사료 첨가제, 산란계에 백신 주사 시 adjuvant 종류, target균 외의 첨가균의 여부에 따른 계란 내의 면역 단백질 생산을 비교 측정하였다. 참숯의 급여에 의한 면역처리구의 specific IgY 함량을 보면 0.5% 참숯을 급여한 처리구가 가장 높은 함량을 나타내었으며, specific IgY의 생산에 참숯의 급여가 큰 영향을 미치는 것으로 나타났다. Adjuvant 처리에 따른 total IgY 함량의 변화는 거의 없는 것으로 나타났으나 specific IgY는 Freund's adjuvant를 사용하여 백신 처리한 처리구에서 높게 나타났다. Adjuvant 사용 시 결핵균을 같이 첨가한 경우 더 많은 specific IgY가 생성되었으나, 수산화 알미늄 처리구에서는 결핵균 첨가에 의한 영향이 나타나지 않았다. 15주령에 면역처리를 해준 경우 21주령에 면역처리를 해준 경우 보다 산란율이 높았으며, 사료에 참숯을 첨가한 경우 일반사료 급여군에 비해 산란율저하가 완화되었다.

In order to produce the antibody rich eggs against Salmonella gallinarum(S.G.) causing fowl typhoid, the productions of immunoglobulin in eggs were compared and examined with the feed additives, the variety of adjuvants in vaccines to layers, and the existence of additive antigens other than target microorganism. The examination of the average contents of specific IgY in immunized group by supplying hardwood charcoal showed that the group supplied with 0.5% hardwood charcoal had the highest contents, implying that the supply of hardwood charcoal promoted the production of specific IgY. Adjuvant appeared to have little effect on the average contents of total IgY, but specific IgY contents increased in the immunized group with Freund's adjuvant. Addition of BCG in adjuvant treatment increased specific IgY however, this feature was not seen in aluminum hydroxide treated group. Immunization at 15 week layers resulted in higher laying rate than immunization at 21 week and addition of hardwood charcoal in feed recovered laying rate. It was therefore, concluded that the feed supplement, such as hardwood charcoal followed by a proper immunization program concerning adjuvant, vaccination period and supplementary microorganism hastened the production of IgY.
