A good few farmers are reporting higher than normal levels of clinical mastitis and high somatic cell count (SCC). When faced with a problem, the first thing to identify is the type of mastitis – environmental or contagious. A lot of mastitis around this spring can be explained by the fact that most herds have been housed for longer periods than normal and this has increased the risk of environmental mastitis such as Strep uberis. Preventing this type of mastitis is down to hygiene – cleaning and disinfecting cubicle beds and calving pens. When cows go to grass the infection pressure will decrease greatly.
