Calf- and herd-level factors associated with dairy calf reactivity

Building a healthier Irish dairy herd through improved calf health

Main results:  In general the colostrum quality (112 g/l I dairy herds of mixed breed is high (50 g colostrum). Older parity cows, cows that smaller quantity of colostrum and cows tha with higher IgG concentration. Reducing colostrum is the most practical means by w  Calves fed 8.5% of birth bodyweight in concentration of IgG in serum in the first 3 Feeding calves transition milk subsequent a...

Reducing Dairy Calf Mortality

The loss of dairy calves from stillbirths and disease-related deaths places a significant challenge on the producer who wants farm-specific replacement heifers to maintain or expand herd size. Stillbirths are often overlooked as an important cause of calf mortality, as they are on some dairies. With improved record keeping, data analysis, diagnostic testing and herd monitoring, the appropriate ...

Herd factors associated with dairy cow mortality.

Summary studies of dairy cow removal indicate increasing levels of mortality over the past several decades. This poses a serious problem for the US dairy industry. The objective of this project was to evaluate associations between facilities, herd management practices, disease occurrence and death rates on US dairy operations through an analysis of the National Animal Health Monitoring System's...

Feeding the Newborn Dairy Calf

Factors influencing dairy calf and replacement heifer mortality in France.

Herd-level risk factors for dairy calf and heifer mortality in France were identified by calculating herd-level variables (including mortality risk or rate) using the National Bovine Identification Database (2005 and 2006). Eleven dairy production areas representing different livestock systems were also included. Statistical analyses were based on a probit model (mortality risk or rate=0 or >0)...
