“…Moreover, animals fed the FDOI diet had greater amounts of secretory IgA and IgG (only in jejunal) in both jejunal and ileal digesta which would likely play a vital role in protecting the gut from invading pathogens and in doing so it may suppress inflammatory processes (Parlesak, Schäfer, & Bode, ). Reports have shown oral administration of bovine colostrum stimulated non‐specific immunity of the host by up‐regulating the systemic immune response or by modulating immunocompetent cell function (Sugisawa, Itou, & Sakai, ; Ulfman, Leusen, Savelkoul, Warner, & van Neerven, ). Based on the study of Balan et al (), feeding rats with ovine Ig could have enhanced their innate immunity by improving phagocytic activity of PBLs and also enhanced T‐cell function by increasing IFNγ secretion in the presence of mitogens.…”
