Control of mastitis by hygiene and therapy.

Hygiene and therapy are two important components of a program to control mastitis. Conscientious application of these practices significantly reduces intramammary infection, especially when they are applied in concert with superior management. The two components operate independently, and response is maximum when both are applied. Hygiene acts by reducing the frequency of infection. The primary effect of therapy is to increase the rate of eliminating established infections, although dry cow treatment also provides prophylactic benefits. The most effective hygiene and therapy practices are dipping of teats after milking and treating each quarter at the end of lactation.
