Calf mortality in Norwegian dairy herds

Abstract: The aims of this study were to estimate mortality rates in Norwegian dairy calves and young stock up to 1 yr of age, identify risk factors for calf mortality, and evaluate the etiology of calf mortality based on postmortem analyses. The material comprised 3 data sets. The first data set included information on 289,038 offspring in 14,474 dairy herds registered in the Norwegian Dairy Herd Recording System (NDHRS) in 2005. The second included recordings on 5,382 offspring in 125 Norwegian dairy herds participati… Show more

“…This compares unfavourably with mortality rates reported for other European countries; Gulliksen et al (2009) reported a lower mortality rate of 3.7% for calves in the same age group in Norway. Presently, there is a lack of published data on the colostrum quality of Irish dairy cows, and as such it is not known whether production of colostrum with a low IgG concentration may be a contributory factor to the high calf mortality rate in Ireland.…”

“…As herd size expands, the task of the manager changes; human resource, financial, operational, herd management and strategic management skills are most important for successful expansion (Hadley et al, 2002). Although benefits of scale have been reported for milk production (Oleggini et al, 2001) and milk quality as a result of lower somatic cell count (Norman et al, 1999;Oleggini et al, 2001), a number of studies have shown increased herd size to be associated with poorer reproductive performance (Oleggini et al, 2001;Washburn et al, 2001), higher calf mortality (Gulliksen et al, 2008), poorer hoof health (Wells et al, 1999;Smith et al, 2000) and a higher rate of involuntary culling (Oleggini et al, 2001).…”

“…Care of the calf begins before birth. Appropriate feeding of the dry cow (Mulligan and Doherty, 2008), calving facilities and calving management are all essential to optimizing the health of newborn calves (Gulliksen et al, 2009a). Over or underfeeding the dry cow influences her body condition score (BCS), changes in which may lead to a greater incidence of dystocia (Berry et al, 2007) thus appropriate nutrition of the dry cow is crucial.…”

“…In addition to dry cow nutrition, monitoring of the cow around calving is important for successful healthy calf births (Lombard et al, 2007). Furthermore, management of hygiene in the calving area is attributable to the exposure of calves to pathogens and the associated impact on infection in the calf (Gulliksen et al, 2009a).…”
