While summer in the south west means lots of visits to the beach, it also means lots of hot cows (and hot farmers and hot vets). As well as the heat from the sun and surrounds, cows have an increased challenge in that their rumen is a massive fermentation vat that also produces heat. Heat
Bacteria are amazing little critters. They can do so much good, such as fermenting the feedstuffs in cows’ rumens to provide them with the nutrients to live, grow and produce milk. They can also do so much bad, for example E. coli and Salmonella can cause severe diarrhoea and sometimes death in calves.
