STILLBIRTH IN DAIRY CATTLE: REVIEW
Keywords:
dairy cattle, stillbirth, genetic and non genetic factors, economic loss animal welfare, consumer acceptance, corrective actionsAbstract
Findings of research and experiences gained in commercial practice reveal needs for
efforts in order to reinforce further development in the subject matter of calving difficulty
and stillbirth in dairy cattle with special emphasis on causes and effects. Direct costs such
as loss of calf, death of dam, labour, veterinary assistance and other ones influencing
economics in longer term e.g. higher culling rate, reduced milk yield and fertility have to be
evaluated and interpreted. The effects of non-genetic factors, parity, sex of calf, age at first
calving, season, level of nutrition during gestation and their supposed modes of action has
to be considered. In the genetic model for calving traits estimates the following components
has to be included such as direct, maternal, and direct-maternal interaction. Thus, accurate
and complete reporting of calving ease and stillbirth data is critical for several reasons:
increase the accuracy of sire calving ease and daughter calving ease evaluations; allow the
development of national stillbirth evaluations; the farmer can enhance future sire selection
opportunities for the herd. The aim is to reduce economic losses, improve welfare status of
animals, meeting increased concern of consumer acceptance of milk and dairy products.
