This past summer has been a big issue of increased infection of dairy cows due to strep uberis
How to avoid Strep uberis?
What the experts say about preventing strep uberis mastitis in dairy cows.
Hygiene in Husbandry Conditions
An intramammary infection is initially preceded by contamination of the teats or the udder surface, whereby in indoor housing the risk of contamination during the housed period is determined by the design of the lying surfaces, the space per cow, the bedding material, the regularity of bedding addition, cleaning and disinfecting as well as the cows´ length of stay in the cubicles.
The fact that the rate of infection with environmental bovine mastitis is highest during the summer months accounts for increased bacterial counts in the bedding material. The indicator for the optimization effort in hygiene of the resting area is the cleanliness of the teats.
The objective should be for more than 90% of the animals to have only a few coarse dirt particles on the teats, which can be removed by simply wiping with a disposable towel or something similar. Feeding imbalances as well as fluctuations in the dry matter intake of the animals seem to affect the rate of clinical Strep. Uberis mastitis in dairy cows.
Machine milking can lead to the proliferation of Strep. Uberis into the glands, which can be avoided by carefully cleaning the teats prior to milking. This can, but does not have to, be carried out by means of disinfecting measures before milking.
A crucial point is that about 95% of the teats leave no or only slightly coloured residues on the disinfecting cloth with which they have had contact before the milking clusters are attached.
All the evidence points to cleaning the actual teat end.
If you’re using too much water, look at the housing and bedding.
The most evidential success of reducing strep uberis is to treat at the dry period
