Testing nutritional supplements to reduce mastitis risk during dry period

The risk of a dairy cow contracting a new case of mastitis increases when we "dry off" the gland during the last ​Kody_ITS.jpgtwo months of gestation to minimize stress on the cow during late gestation and give the mammary gland time to relax and regenerate (=dry period). We dry off the gland by not milking the cow. This allows milk to temporarily build up and the teat canal remains a bit more 'open', allowing bacteria to enter. Also, since she is not being milked, we do not sanitize the teat 2-3 times per day prior to milking - allowing bacteria to build up on the teat surface.

Kody's (his hands are pictured to the right) research project is evaluating the ability of a nutritional supplement to reduce the risk of new intramammary infections during the dry period when used in combination with an internal teat sealant (ITS; also pictured) that prevents bacterial entry into the gland. Any quarters that have an infection prior to 'dry off' will be treated with antibiotics directly in the gland. Kody also will test if the nutritional supplement helps clear existing infections.

We are in the early stages of this research, so stay tuned to see how it turns out!
