The aim of this study was to evaluate the effects of the Fusarium toxin zearalenone (ZEA) and/ or deoxynivalenol (DON) on the serum IL-1, IL-4, and C3 levels in mice. In our study, 360 healthy adult female mice were randomly assigned to 9 groups for a 12-day study. Mice of all groups were given a 4-day continuous intraperitoneal injection with different concentrations of ZEA alone, DON alone, and the mixture of ZEA and DON, individually. Blood samples were collected in days 0, 3, 5, 8, and 12 of the experiment. The experiment results showed that all of the experimental groups could cause the dysregulation of the IL-1, IL-4, and C3 levels, thus affecting the immunity of mice. The mixture groups, especially in the group with higher concentrations of ZEA and DON (Group D2Z2), showed more obvious effect on the dysregulation of the IL-1, IL-4, and C3 levels. There was a synergistic effect between DON and ZEA. [ABSTRACT FROM PUBLISHER]

The aim of this study was to investigate the effects of dietary antimicrobial peptide (AMP) supplementation on the serum IgG, IgM, IgA, classical swine fever antibody (CSF-Ab), and total complement (CH50) levels in weaned piglets. Ninety weaned piglets were randomly allotted to five groups for 28-day study. Blood samples were collected at 32, 39, 46, and 53 days of age. The results showed that AMP as dietary additive increased the levels of IgG, IgM, IgA, CSF-Ab, CH50 among the whole experimental period, and the effects of AMP supplementation were dose-dependent. The study showed that supplementing weaned piglets diets with AMP enhanced the humoral immune responses of weaned piglets by improving the levels of classical swine fever virus antibody, CH50, and immunoglobulins. We suggest the dosage of AMP was 500 mg/kg. [ABSTRACT FROM PUBLISHER]
