Preface
Mastitis has been one of the most studied diseases in the dairy industry in recent decades.
The reasons for this interest are obvious. Mastitis affects the health of dairy cows. A large
proportion of cows suffer from mastitis and it is one of the most important reasons for culling.
Mastitis is thus responsible for a decrease in farm profitability, a decline in animal welfare
and a reduction in the farmer’s job satisfaction. Moreover, mastitis negatively influences milk
quality and this affects dairy processing.
Since 2005 a great number of mastitis research projects have been started in the Netherlands.
The scope of each of these projects is different but they have one thing in common, they are
all directed towards the improvement of on-farm udder health: from science to practice. And
that is why the Dutch dairy industry took the initiative to organise an International Conference
on Mastitis Control with this ‘science to practice’ theme.
This book reflects the latest knowledge on mastitis control. Out of more than 120 abstracts,
the Scientific Committee selected 42 oral presentations. This book contains the six-page
papers of each oral presentation given during the conference and the abstracts of each poster
presentation.
Because we believe that scientific evidence is an important foundation for effective mastitis
control, the conference was aimed at science that is useful in practice. The International
Conference entitled ‘Mastitis Control: From science to practice’, was held from 30 September
to 2 October, 2008. Approximately 350 people attended the conference.
Finally, we would like to acknowledge all the people that have been involved in the organisation
of the conference.
