Prevalence of failure of passive transfer of immunity in newborn heifer calves and associated management practices on US dairy operations.
Failure of passive transfer of immunity (FPT) in dairy replacement calves has been linked to increased neonatal morbidity and mortality and long-term decreases in productivity. The purpose of this study was to estimate the prevalence of FPT in US dairy heifer calves in 2007 and to use nationally representative data to investigate associations of FPT with colostrum and calf management practices....

The experiment was performed on a working dairy where 40 50% of the heifer calves had been dying because of poor colostrum quality. For three months, May 12, 1999 through August 10, 1999, the heifer calves born were fed 4 L of first colostrum through...
متن کاملManagement practices associated with high mortality among preweaned dairy heifers.
In a national survey of US dairy operations, 1685 dairy operations reported 47,057 new dairy heifers (either births or acquisitions) and 4427 deaths (9.4%) of preweaned dairy heifer calves over a 3 month period. Stepwise logistic regression was used to identify management practices associated with high mortality among preweaned heifers in dairy operations where at least three dairy heifer calve...
متن کاملFactors Affecting High Mortality Rates of Dairy Replacement Calves and Heifers in the Tropics and Strategies for Their Reduction
The tropics is not an ideal location for calf rearing as the high temperatures and humidities introduce many potential disease problems to milk fed calves. In addition, the type of dairy farming (generally poorly resourced small holder farming) and the general lack of awareness of the long term implications of poorly reared stock do not encourage farmers to pay close attention to their calf and...
