Which breed of dairy cattle is resistant to mastitis?

Which breed of dairy cattle is resistant to mastitis?

Holstein Friesian dairy cows
In Holstein Friesian dairy cows, selective pressure for increased milk production has led to a higher propensity to disease, including mastitis, when compared to less selected and lower producing dairy breeds. The biology underpinning the higher resistance to disease of such “local breeds” is not fully understood.

What are the objectives of the bovine mastitis study?

The objectives of the study were to estimate the prevalence of mastitis, identify the cow-and herd-level potential risk factors and isolate Staphylococcus aureus, one of etiological agents for contagious mastitis, from cows positive for mastitis.

How many cows were tested for mastitis in California?

A total of 529 lactating cows selected randomly from 95 herds were screened by California mastitis test (CMT) for sub-clinical mastitis. Also 172 milk samples collected from CMT positive cows were cultured for isolation of S. aureus.

What’s the prevalence of mastitis in dairy herds?

Over the years a number of researchers have studied the occurrence of mastitis in dairy herds in Ethiopia. According to the most recent published studies, the cow-level mastitis prevalence estimate falls within the range of 23.2 and 81.1% for the country [ 10 – 16 ].
