Pasteurization of colostrum reduces the incidence of paratuberculosis in neonatal dairy calves.
In the present study, the potential benefits of feeding pasteurized colostrum were demonstrated in calves born to dams naturally infected with Mycobacterium avium ssp. paratuberculosis. Calves were separated at birth from their dams and randomly allocated into a group fed either the colostrum of their dam (DC; n = 6), followed by feeding the milk of the dam for 3 wk and then milk replacer, or i...
متن کاملColostrum management for dairy calves.
Colostrum management is the single most important management factor in determining calf health and survival. Unfortunately, a significant proportion of North American dairy calves suffer from failure of passive transfer of antibodies from colostrum, contributing to excessively high preweaning mortality rates and other short- and long-term losses associated with animal health, welfare, and produ...

The 2002 NAHM's Dairy Survey indicated that 87.2% of dairy farms in the United States feed waste milk to their neonatal calves. Although cost-effective, this practice can lead to increased calf morbidity and mortality due to ingestion of pathogenic agents. In an effort to reduce the risk of infection, dairy producers are implementing on-farm pasteurization of the waste milk as a control procedu...
متن کاملNeutrophil and Monocyte Function in Neonatal Dairy Calves Fed Fresh or Frozen Colostrum
A study was conducted to compare neutrophil and monocyte activation in neonatal dairy calves fed fresh or frozen colostrum. Fifteen male Holstein calves were fed either refrigerator-stored, non-maternal colostrum or frozen, non-maternal colostrum. Blood samples were collected at days 2 and 21 of life to determine phagocytic cell function using flow cytometry. Serum immunoglobulin concentration ...

total protein intake. The estimated percentage of ruminal bypass of feed protein was only slightly higher in cows fed extra-heat SBM compared to the control group (28.8 vs 27.8 percent). Therefore, based on these data and those in the feeding trial, it appeared that the extra-heat SBM (PDl-IO) used in this trial was not heated extensively enough during processing to make it a high bypass feed p...
