Intramuscular injections in livestock are typically used to administer which of the following?

Intramuscular injections in livestock are typically used to administer antibiotics due to several reasons. Antibiotics are essential in treating infections or preventing disease, and delivering them via intramuscular injection allows for quicker absorption into the bloodstream. This method can help achieve effective therapeutic levels more rapidly than oral administration.

While other substances, such as vitamins or hormones, can also be administered intramuscularly, antibiotics are specifically relevant for the treatment of bacterial infections in animals. Blood products may be administered through different routes depending on the desired effect and urgency, making antibiotics the more common choice for intramuscular injection in livestock management.
