Antioxidant injections during the transition period helped in improving total immunoglobulin levels in crossbred cattle plasma

Abstract

Immunoglobulins (Ig) are important factors in the immunological activity of milk and colostrum from dairy cattle. The primary immunoglobulin in cow colostrum and milk is IgG, which can bind to a wide range of pathogenic bacteria and viruses. Bovine IgG can exert its effects on several levels, including: Direct effects on potential pathogens, Enhancing clearance of pathogens, Influencing intestinal barrier function, and Modulating immune function. The study was conducted to evaluate the effect antioxidant injections on the levels of total immunoglobulins in the crossbred cattle plasma. Four groups T1, T2, T3 and T4 were created consisting of six crossbred animals each. Group T1 was used as control group and was fed only basal diet. T2 group was injected with multi-mineral injections, T3 was injected with multivitamin injections and T4 was injected with combination of multivitamin and multimineral injections. They were injected on 7th, 15th, 21st, and 30th day before parturition. T4 group showed the highest increase in immunoglobulin levels in the plasma (p
