Australian cows suffer more mastitis
Australian cows are afflicted with more mastitis because there is pressure on dairies to raise milk output.
Mastitis is an infection of the udder and is costly to treat. Infected cows cannot be milked for at least a week.
Dairy Australia vet Dr John Penry said mastitis has increased by 30% in the past 15 years.
He said wet conditions in eastern Australia are only part of the problem.
"So herd sizes have become bigger, cows are more densely populated within the farming system.
"There is more access of cows to where there is a reasonable amount of cow faeces.
"We have got a higher rate of stocking and more ability for more cows to be in the one place at the one time."
