Fermented or Chemically-Treated Colostrum and Nonsalable Milk in Feeding Programs for Calves

Farming practices in Sweden related to feeding milk and colostrum from cows treated with antimicrobials to dairy calves

BACKGROUND Milk produced by cows in receipt of antimicrobial therapy may contain antimicrobial residues. Such antimicrobial-containing waste milk must be withdrawn from human consumption and is therefore sometimes used as calf feed. Unfortunately, this approach might promote selection of antimicrobial resistant bacteria in the calves' intestinal microbiota. The objectives of this study were the...

Heat-treated colostrum feeding promotes beneficial bacteria colonization in the small intestine of neonatal calves.

The present study investigated the effect of heat-treated colostrum feeding on the bacterial colonization in calf small intestine of neonatal calves within the first 12h of life. Newborn Holstein bull calves (n=32) were assigned to 3 treatment groups and fed with either fresh colostrum (FC, n=12) or heat-treated (60°C, 60 min) colostrum (HC, n=12) soon after birth, whereas the control (NC, n=8)...

Proteinuria in New-born Calves following the Feeding of Colostrum

The evidence presented indicates clearly that the feeding of colostrum is responsible for the proteinuria. Observations on many calves killed within the 3 first days have shown that this condition is nearly universal and that it disappears after the 3rd day, even when the calf is not quite normal. Urine of fetuses and unfed calves did not contain it. By feeding different amounts of colostrum, b...
