Effects of selenium supplementation during different trimesters of pregnancy on non-specific humoral immunity of pregnant beef cows and persistence of antibodies in their newborn calves

Creator:

Thompson-Hernandez, Ian

Abstract:

Immunosuppression during the periparturient period leads to increased susceptibility to infectious diseases in beef cows. Newborn calves rely on passive transfer of antibodies from their mothers at birth for protection against diseases in the first two months of age. It is unknown if supranutritional Se supplementation of cows during pregnancy...

Effects of Selenium Supplementation During Different Trimesters of Pregnancy on Total and Vibrio coralliilyticus Specific IgM Antibody Concentrations in Beef Cows at Parturition

Creator:

Zurita Cruz, Cindy

Abstract:

Background: The immune response to microbial infections is compromised in beef cattle at parturition. Innate and adaptive immunoglobulin M (IgM) serve as initial antibodies during microbial infection before the generation of adaptive immunoglobulin G (IgG). Selenium (Se) is an essential micronutrient required by all mammals, which can improve immune responses...
