중탄산소다 함유 대두유 사료는 급성기 반응에 의한 생산성(증체, 사료효율, 칼슘밸런스, 뇨질소 배설량 및 NB) 감소 완화작용이 있었으며, 이때 에너지원의 흡수 증가에 의한 대사에너지 값의 상승과 인 발란스의 증가 및 적혈구 세포액중의 SOD 및 순환 세룰로플라민스의 활성 감소가 관찰되었다. 본 결과는 급성기 반응중의 사료에너지 이용과 전해질 농도는 항산화계의 변화와 상관관계가 있다는 것을 나타내었다.
Effects of interaction of dietary soybean oil with NaHCO$_3$on the energy metabolism and antioxidants enzyme activity in broiler chicks during acute phase response was studied, Broiler chicks 10 d-old were fed on diets containing 5.0 ％ of soybean oil with or without 0.5 ％(60 meq/kg) of NaHCO$_3$. Then acute phase response were induced by injecting Salmonella typhymurium lipopolysacharide(LPS) In saline 3 times i.p. at alternative day on 16-d of age. Dietary soybean oil with NaHCO$_3$lessened the performance(growth, feed efficiency, calcium balance, excretion of uric acid, and nitrogen balance) -suppressing effect of the LPS effect, but enhanced metabolizable energy value of diet due to increased digestive absorption of energy sources and phosphoruse balance, and decreased activities of SOD in erythrocyte cytosols and circulating ceruloplasmin in plasma. The results indicated dietary energy utilization and electrolytes levels may interact with the antioxidants systems during acute phase response.
