Summer concern

SUMMER mastitis incidence in dairy herds has reduced little since the 1970s and prevention is still crucial, said Axient mastitis vet Elizabeth Berry.

A recent survey showed that pregnant and non-pregnant heifers and dry cows are most at risk, but cases could occur in calves and bulls.

She concluded that dry cow therapy and fly control remained important for prevention. But she found little difference between the method of fly control and summer mastitis incidence.

"Summer mastitis is a welfare issue and prevention should be used," said Ms Berry.
