자돈에서 Sus scrofa ferritin Heavy-chain생산 재조합 효모의 효과

초록

Iron deficiency anemia is also recognized as a serious disorder in many livestock, especially, piglets. We previously studied that the iron-fortified yeast (Saccharomyces cerevisiae) producing Sus scrofa ferritin heavy-chain (FER) was bioavailable to mice with iron deficiency. In this study, we determined whether FER could improve iron deficiency in piglets. The bioavailability of FER was examined by measuring body weight gain, hemoglobin concentration and hematocrit value in suckling and weaning piglets. We found that FER significantly increased hemoglobin value and the hematocrit ratio in suckling piglets (P＜0.05). Furthermore, FER treatment significantly enhanced body weight gain in both groups of the suckling and weaning piglets (P＜0.05). These results suggest that the iron-fortified recombinant yeast strain is helpful in iron absorption in piglets.
