Description: Management of the transition dairy cow is key to future reproductive success, reduction of disease and lessening the incidence of metabolic disorders (Horst et al., 2021). Stimulation of the immune system during late gestation with choline, synthetic zeolites or other nutraceutical approaches may help prevent unwanted health consequences during the early lactation period (Riboni et al., 2019; Crookenden et al., 2020; Zenobi et al., 2020). A recent study demonstrates that injection of non-pathogenic mycobacterium cell wall fractions as an immunostimulant improves subsequent fertility rates in dairy cows and may offer another method for improving periparturient cow health (Solano-Suarez et al., 2021).
