Evaluation of management factors influencing the transition success in cattle on Dutch and Flemish dairy farms
Summary
This observational study provides information about management strategies on Dutch
and Flemish dairy farms that possibly affect the transition period of the cow. A survey
covering more than 90 questions, based on seven themes related to the management in
the periparturient period was conducted on 36 farmers (17 from the Netherlands and 19
from Belgium). The results were visualized and linked to a new key performance
indicator: the lactation onset value (LOV). This KPI is created to provide a method for
benchmarking the success of transition on different farms throughout Europe. The
participating farms were compared with each other for each question by their calculated
LOV’s. Factors which were associated with a better LOV were the occurrence of more
than 100 calvings per year versus less than 100 and the introduction of the heifers into
the lactating group versus the dry cow group. Other factors associated with a better
LOV, but based on a small group of farmers, were feeding one ration during dry off
versus two rations and taking milk reducing measures to all cows before drying off,
instead of some cows. In conclusion, a large number of calvings per year, the
introduction of heifers into the lactating herd, feeding a stable ration during the dry off
period and taking measures to reduce the milk production before dry off for all cows
might be success factors for the transition period. Now that a broad insight of the results
and their influence on transition has been gained, more extensive statistical models
should be set up and follow-up research should be carried out that zooms in on these
aspects.
