“…Presumably, for herds with relatively poor livability improvements could be achieved by, for example, improved supervision of the animals around parturition (Mee et al, 2014). However, such adaptations may be difficult to realise in practise.…”

Death of calves around parturition is a matter of concern for dairy farmers. Relatively high stillbirth rates and unfavourable trends have been reported for Holstein heifers in the Netherlands and several other countries. In our study, we investigated herd differences, genetic parameters and genotype by environment interaction for heifer calf livability. A large dataset with data from calvings between 1993 and 2012 of Dutch dairy farms was used. There were considerable differences between herds in livability of calves from heifers, with averages ranging from 74% to 95%. Both herds with relatively high and low averages showed the same negative trend between 1993 and 2012, with largest declines in herds with the lowest averages. We found that heritability and genetic variation of first parity livability were substantially larger in herd environments where the likelihood of stillbirth was high v. environments where stillbirth was at a low level. The genetic correlations between herd environment levels were all very close to unity, indicating that ranking of sires was similar for all environments. However, for herds with a relatively high stillbirth incidence selecting sires with favourable breeding values is expected to be twice as profitable as in herds with a relatively low stillbirth incidence.

“…The choice to develop a predictive model for this moment was based on the idea that it is important that a farmer is present shortly after calving has started. A farmer`s presence is important because farmers need to be aware of dystocia as soon as possible to mitigate adverse effects (Barrier, et al, 2013, Mee, et al, 2014. It is also important that a calf is fed colostrum shortly after birth, preferably within one to two hours (Conneely, et al, 2014, Klein-Jobstl, et al, 2014.…”

“…breed and parity), calf gender (Norman, et al, 2010) calf weight and management (e.g., housing and pre-calving movement) (Mee, et al, 2014, Piwczynski, et al, 2013. Farmers can influence these risk factors through management, for instance, by changing their breeding strategy but also by human supervision during the calving process.…”

“…Lombard et al (2007) observed that 24% of stillbirths occurred with unassisted calvings. Supervision during the calving process, which enables appropriate intervention, is therefore likely to reduce the number of stillbirths and other health and welfare effects that dystocia has on calves and dairy cows (Barrier, et al, 2013, Mee, et al, 2014.…”

“…Providing proper and timely assistance at calving can significantly reduce calf morbidity and mortality, especially when dystocia occurs (Lombard, et al, 2007). Next to the effect on the calf, timely calving assistance reduces parturition stress and improves the cow's reproductive performance (Barrier, et al, 2013, Mee, et al, 2014, Palombi, et al, 2013. Timely detection of the start of calving is therefore important to ensure timely assistance.…”
