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)...
متن کاملEffects of feeding heat-treated colostrum on passive transfer of immune and nutritional parameters in neonatal dairy calves.
The first objective of this study was to describe the effect of on-farm heat treatment of colostrum on colostral bacteria counts and IgG concentrations. The second objective was to describe the effect of feeding heat-treated (vs. raw) colostrum on passive transfer of colostral immune and nutritional parameters in neonatal calves. Pooled batches of colostrum were mixed and divided equally: one h...
متن کاملProteinuria 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...
متن کاملFeeding colostrum, its composition and feeding duration variably modify proliferation and morphology of the intestine and digestive enzyme activities of neonatal calves.
We studied the effects of amounts of colostrum consumed on intestinal morphology and proliferation and digestive enzyme activities in neonatal calves. Group GrCmax calves were fed colostrum from the first milking undiluted on d 1-3 and diluted with 25, 50, 75 and 75 parts of a milk replacer on d 4-7. Group GrC1-3 calves were fed colostrum from milkings 1-6 up to d 3 and then a milk replacer up ...
متن کاملFormulation of colostrum supplements, colostrum replacers and acquisition of passive immunity in neonatal calves.
Provision of an adequate mass of IgG from maternal colostrum is essential to health and survival of neonatal calves. Colostrum supplements (CS) have been developed to provide supplemental immunoglobulin when maternal colostrum is of poor quality. However, colostrum replacers (CR) that provide > or = 100 g of IgG have not been formulated. Our objective was to determine the absorption of IgG in n...
