According to the invention, this is achieved in that silver, in particular in combination with magnesium, is used in an intramammarial manner.

The first research project for which I obtained financing1 focused on characterizing the bacterium in a context of intramammary infection.

Early detection of intra-mammary infection reduces its severity, improves control and limits milk quality penalties.

The method includes the step of administering, by intramammary delivery, a therapeutically effective amount of a polyether ionophore, or a therapeutically acceptable salt thereof, to the mammary gland of the subject.

Therefore, overall treatment length must be at the veterinary surgeon’s discretion but should be long enough to ensure complete resolution of the intramammary infection.

IVIg products have been shown to cross the placenta, increasingly during the third trimester.

Therefore, the total duration of treatment may be left to the decision of the veterinarian, but it must be long enough to ensure complete resolution of the bacterial disease.

When administering a tube of antibiotics intra-mammary, especially in a high producing cow, it can be difficult to achieve a good concentration in all parts of the mammary gland.
