It is critical that bovine maternal colostrum is fed to newborn calves during their first hours of
life. Colostrum is the secretion a cow produces after mammary involution that is rich in …

Colostrum-derived passive immunity is central to the health, performance and welfare of
neonatal beef-suckler calves, and economics of beef-farming enterprises. Compared to …

Neonatal dairy and beef calves are required to ingest adequate volumes of high-quality
colostrum during their first hours of life to acquire transfer of passive immunity (TPI). As such …

Newborn calves are agammaglobulinemic and rely for their first immune protection almost
completely on the transfer of immune constituents via colostrum. Inadequate colostrum …

Our objectives were to evaluate the impact of supplementary trace mineral (TM) form—
inorganic salts (STM; Co, Cu, Mn, Zn sulfates, and Na selenite) or organic (OTM; Co, Cu, Mn …

The objective of this study was to analyze if maternal supply of rumen-protected protein
during the dry period can affect the IgG concentration and microbial composition of …

For centuries, multicellular organisms have lived in symbiosis with microorganisms. The
interaction with microorganisms has been shown to be very beneficial for humans and …

Conflicting reports exist on whether prolonged IgG consumption can further increase serum
IgG in neonatal calves. Given that higher serum IgG in neonates has lifelong benefits, our …

Calves might experience an upper limit of IgG absorption from colostrum ingestion at birth,
but it is not clear whether the total IgG mass fed in the first meal or feeding frequencies can …

Influence of supplementing Moringa olifeira leaf meal (MOLM) to Holstein cows on (1)
