Dairy production: our teams innovate to better target the treatment of mastitis at dry-off

Dairy production: our teams innovate to better target the treatment of mastitis at dry-off

On February 21, our farm animals team organized a webinar attended by nearly 900 veterinarians from all over the world. The objective? To present our new Smart DCT tool, which allows a better assessment of the infectious pressure in dairy herds during the dry period. This action aims at supporting better adapted treatments and a more responsible use of antibiotics.

Mastitis is a disease that affects an average of 40% of dairy cows1 and causes severe inflammation of the mammary gland and udder tissue. Acute cases can be fatal, and even in treatable cases there is a significant risk of permanent udder damage that affects lactation, sometimes on a long-term basis. The cost of treatment and the reduction in milk production due to infection can also result in heavy losses for the farmer.

In two-thirds of cases, mastitis occurring in the first month of lactation is due to an infection contracted during the cow's dry period2. In order to avoid the spread of this infection within the herd and to avoid prophylactic treatment with antibiotics of all dry cows, a precise selection of cows to be treated is key. However, this selection is difficult because sick animals do not always show visible clinical signs.

This is why our teams have developed Smart DCT. This innovative tool allows veterinarians to calculate and adapt the treatment threshold according to the prevalence of mastitis in the herd. The higher the prevalence, the lower the treatment threshold (somatic cell count) and vice versa. The Smart DCT calculator thus helps to better target the animals to be treated and avoid treating healthy animals, according to the real infectious pressure in the herd.

On February 21, our teams presented this new tool to nearly 900 veterinarians from around the world during a webinar dedicated to mastitis management, organized in close collaboration with Professor Sofie Piepers3 , a recognized expert in this field. This success confirms our commitment to providing cattle professionals with effective and practical solutions that simplify their daily lives while preserving the quality of life of the animals.

Because healthy cows produce quality milk, we make their health and well-being a priority by providing solutions and protocols for a more qualitative and sustainable milk production.
