why should i milk culture?

1 because she might be
infecting the rest of the herd

Mastitis caused by bacteria such as Staphylococcus aureus, Streptococcus agalactiae and M. bovis is contagious. The udder is the source of the infection, which is why it is most often spread through the milking process. Knowing the carrier and bacteria at play is key to choosing the appropriate treatment and controlling the spread of the disease across your herd.

Testing first means being confident in your treatment of choice and targeting mastitis at the source.1

2 because you may be needlessly
losing milk and money

According to the Canadian Bovine Mastitis and Milk Quality Research Network, 40% of milk cultures from clinical cases show no growth1, meaning treating with intramammary antimicrobial may be unnecessary.

Performing a milk culture test can help save you money, milk and time.
