A what injection is made into the udder through an opening in the teat?

1. Intravenous

2. Intramammary

3. Subcutaneous

4. Intramuscular

The correct answer is: Intramammary

An intramammary injection is specifically designed for administration directly into the udder of lactating animals, such as cows and goats. This method involves delivering medication through the teat opening, allowing for targeted treatment of conditions such as mastitis, which is an infection of the mammary gland. By injecting directly into the udder, the medication can act locally at the site of infection, leading to more effective treatment with potentially fewer systemic effects. This injection method contrasts with others. Intravenous injections involve delivering substances directly into the bloodstream through a vein, which is not suitable for localized conditions within the udder. Subcutaneous injections involve administering substances beneath the skin, while intramuscular injections are delivered into the muscle tissue. Neither of these methods provides the specificity needed for effective treatment of udder infections. Thus, intramammary injections are the preferred route for delivering medications directly to the mammary glands.
