Bayer presents global dairy cattle health experts at 2nd Dairy Summit

Thought leaders address five core pillars to advancing dairy cattle health: calf resilience, fertility, metabolic health, udder health and well-being download Cattle health experts share and discuss the latest advancements in science and practice in calf resilience, fertility, metabolic health, udder health and well-being at Bayer’s 2nd International Summit on Dairy Cattle.

“We are committed to support dairy professionals with science and practice-oriented approaches in order to advance cattle health and well-being, as well as to further sustainable production.”

The 2nd International Summit on Dairy Cattle, held in Nantes, France, from March 5th – 7th, sees global dairy cattle health and well-being experts come together to share and discuss the very latest advancements in science and practice.

During the summit, a curated panel of global thought leaders is presenting the forefront of research and practice in their respective fields. The discussion centers on five core educational pillars: calf resilience, fertility, metabolic health, udder health and well-being.

The event also helps provide veterinarians with practical approaches to addressing key challenges facing the dairy sector, such as advancing responsible antimicrobial use, sustainable productivity and optimizing communication with clients and colleagues.

Bayer is also discussing its latest work in supporting those in the care of dairy cattle, including a new dry cow intramammary product tailored to the 60 day dry period, Arentor DC™ (Cefalonium).

Dr. Almut Hoffmann, Head of Farm Animal Products at Bayer said: “We are committed to support dairy professionals with science and practice-oriented approaches in order to advance cattle health and well-being, as well as to further sustainable production.

In line with Bayer’s purpose of ‘Science for a better life’, the 2nd International Summit on Dairy Cattle was developed to help stimulate positive change through innovation, promote discussion within the industry on the application of science to address key cattle health and well-being challenges, and further advance sustainability.

Bayer is proud to present the following list of speakers at the summit:

• Professor Mike Van Amburgh, Cornell University, Ithaca, NY, USA
Rethinking Colostrum Management
Colostrum is an important part of early calf development, not only for immune function, but also to stimulate gastro-intestinal development and enhance digestion and metabolism, which can have a large impact on the animal’s health and productivity later in life.

Professor Alex Bach, ICREA and Department of Ruminant Production IRTA, Catalonia, Spain
Optimizing Future Productivity through Improved Weaning and Management of Calves and Heifers
The growth objective for rearing calves and heifers should be based on expected performance – the way they are reared will not only impact their health status and growth as calves and heifers, but it will also impact their longevity and milking ability in adulthood.

• Professor Barry Bradford, Kansas State University, USA
Impact of Inflammation after Calving on Reproduction
Inflammatory signals are essential for the birthing process, but cows with elevated inflammatory signals in the weeks after calving eat less feed, show signs of disrupted adipose tissue function, and suffer more often from metabolic disease.

Hypocalcaemia and its Impact on Health Parameters of Dairy Cows
The onset of lactation causes a large increase in calcium needs almost overnight. In a typical Holstein cow today, 24 hours of colostrum synthesis can require 12 times as much calcium as the entire blood calcium pool. Even a mild hypocalcaemia is associated with increased disease risk and delayed fertility after calving.

• Professor Andrew J Bradley, University of Nottingham, UK
Making Rational Decisions about Antibiotic Use in Mastitis Control: Current Options and Future Possibilities – A UK Perspective
The understanding of mastitis as a disease has evolved and the relative importance of antibiotics in mastitis control in both lactation and the dry period has changed. Furthermore, the use of antibiotics in food-producing animals has come under scrutiny and the responsible use of antibiotics has become increasingly important. Innovative approaches are under development to make rational, evidence based treatment decisions easier in future.

• Dr. Christian Scherpenzeel, GD Animal Health, the Netherlands
Selective Dry Cow Therapy around the Globe; Experiences and Challenges for Udder Health
The move from blanket dry cow treatment to selective dry cow treatment of dairy cows is an important part of the strategy to reduce antimicrobial use in dairy cows. It requires a herd specific dry cow treatment plan tailored to the local requirements.

• Dr. Guillaume Lequeux, LABOCEA Fougeres, France
Antimicrobial Susceptibility of Udder Pathogens in Dairy Herds: French Data and Global Insights
Antimicrobial susceptibility testing could be a useful tool in developing a mastitis management program for dairy herds, guiding veterinarians in selecting the most appropriate antimicrobial. However, other factors also need to be considered when making treatment choices.

• Dr Reuben Newsome, Synergy Farm Health Ltd., UK
Lameness in Dairy Cattle: Managing Claw Horn Lesions on Farm
Lameness is an extremely important disease of dairy cattle, with approximately 30% of dairy cattle in most developed dairy systems globally estimated to be lame at any one time. Lameness has severe and long term consequences on animal well-being and productivity.

• Dr. Peter Edmondson, UdderWise Ltd., UK
Successful Communication for Farm Animal Practice; Staying Ahead in a Rapidly Changing World
The farm veterinarian is a trusted member of the farm team, however, the industry is rapidly changing and veterinarians now need to be proactive, understand farm economics and be up to date with the rapidly changing range of new technologies that farmers are using and are under development. Communications tools can also enhance successful communications in this changing environment.

• Professor Sylvie Chastant-Maillard, National Veterinary School, Toulouse, France
Ovarian resumption of cyclicity in dairy cows: not so easy
It has long been considered that the only important criteria for ovarian resumption of cyclicity was to occur as early as possible. It is now clear that qualitative aspects of the progesterone profiles are also crucial for subsequent fertility.

• Professor Alexander Starke & Dr Melanie Schaeren, University of Leipzig, Germany
Herd health management in the transition period – metabolomics approach to identify treatment options for metabolic diseases
By using the metabolomics approach, complex metabolic alterations of the transition dairy cow can be analysed and mapped. Researchers were able to identify high risk animals based on their metabolite profiles and showed that these alterations were already present prepartum.
