Abstract

Twelve pigs were used to investigate the effects of polyclonal antibody candidate against abdominal (AAb) and subcutaneous adipocyte membrane proteins (SAb) on body weight, fecaldigestibility and blood metabolites. When AAb and SAb developed by Choi et al. (2010) were injected to pigs, the numerical increase in BW (body weight) occurred at 4 weeks post-treatment, but BW for an entire period was also increased, indicating that the BW increase may not be affected by the antibodies injection. Antibodies treatment did not affect (P>0.05) fecal digestibility of dry matter, crude protein, crude fat and crude fiber. Fecal digestibility of crude ash for control (no treatment) at 2 weeks decreased, and that for non-immunized serum treatmentgroup at 4 weeks post-treatment increased, respectively (P<0.05). However, fecal digestibility of crude ash for AAb and SAb groups did not significantly change. At 4 weeks after the antibodies treatment, blood urea N concentration for AAb and SAb groups was significantly increased (P<0.05). However, these increases may not be caused by the antibodies treatment because similar pattern in blood urea N concentration occurred before the antibodies treatment. Antibodies treatment did not affect concentration of plasma glucose and triglycerides (P<0.05). Compared with control, concentration of plasma total cholesterol for AAb and SAb groups at 4 weeks post-treatment was significantly (P<0.05) decreased. This may suggest that body fat reduction possibly occurs. In conclusion, the AAb and the SAb developed by Choi et al. (2010) may have safety in nutritional physiological metabolism in pigs. Further study on in vivo fat reduction of the antibodies against abdominal and subcutaneous adipocytes of pigs should be required for fat-reduced pork production.

본 연구는 비거세돈 12두를 이용하여 돼지 복강 및 피하지방 감소 후보 항체를 생체 주사 처리 시 체중, 분 소화율 및 혈액 대사물질 등 영양생리대사에 미치는 영향을 조사하고자 실시하였다. Choi 등(2010)에서 개발된 돼지 복강 및 피하지방 감소 후보 항체를 피하 주사하였을 때 주사 후 4주까지 평균 체중은 수치적 증가가 발생했으나(P>0.05), 전 기간에 걸쳐 수치적 증가를 보여 항체의 처리로 인한 영향보다는 돼지의 일반적인 성장에 기인하는 것으로 판단된다. 항제 주사 처리 시 건물, 조단백질, 조지방 및 조섬유의 분 소화율은 항체 주사 전, 후 및 시험구 간의 통계적 유의성이 나타나지 않았다(P>0.05). 조회분 소화율의 경우 항체 주사 후 2주째 control에서 감소를 및 4주째 NAb에서 증가를 보였으나(P< 0.05), AAb 및 SAb에서는 유의적 변화가 없었다. 혈액 대사물질의 변화에서는 항체 주사 후 4주의 AAb 및 SAb에서 BUN 농도가 유의적으로 증가하는 것으로 나타났다(P<0.05). 하지만, 후보 항체 주사 전에서도 유사한 패턴으로 유의적 증가를 보여 항체 처리에 의한 차이보다는 개체간의 차이로 사료된다. 혈액 내 glucose 및 TG 농도는 후보 항체 처리에 의한 유의적 차이는 나타나지 않았다(P>0.05). 체지방 함량과 밀접한 관계에 있는 혈액 내 TC 농도에서는 control 대비 후보 항체 주사 후 4주차 AAb 및 SAb에서 유의적 감소가 나타나(P<0.05), 체지방 감소가 일어나고 있음을 간접적으로 추론할 수 있다. 이상의 결과를 볼 때, 본 연구에서 이용된 AAb 및 SAb는 in vivo 영양생리대사에 부정적 영향을 미치지 않는 안전한 항체로 판단된다.
