Abstract

The plane of energy nutrient and supplementation of mineral fed to cows in the prepartum period has been shown to influence energy status, immune response, and metabolic health. However, the effect of supplementation of essential mineral like Zn in the diet on plasma titers antibodies and mineral status in postpartum dairy cows is less known. This study investigated the effect of prepartum Zn supplementation in dairy cows on calcium (Ca) status, titer antibodies in plasma and milk Zn content in dairy cows at week 1 after calving. Lipopolysaccharide (LPS) were used as an antigen. Twenty dairy cows (FH) were randomly assigned to 2 groups: dry cow basal diet (control group; CON) and basal diet with supplementation of Zn 40 ppm (CON+Zn). Both Ca in plasma and Zn milk content were determined by atomic absorption spectrophotometry. Blood and milk sample were taken at week 1 after calving. Results showed there were no significant differences on Ca plasma, titers antibodies (IgG and IgM) and milk Zn among dietary treatments. Numerically, plasma Ca, milk Zn content and IgG binding LPS were higher in cows fed Zn supplementation compared with control group. No significant differences in the status of Ca and Zn and titers IgG binding LPS at week 1 after calving were observed between the 2 groups maybe due to high immune status of these cows. It seems feeding Zn above the requirements before calving maintain immune status, better milk nutrient dense and reduce the incidence of milk fever.
