It does not always need to be antibiotics: healthy pig breeding

The application of antibiotics can be reduced in pig breeding by using antimicrobial peptides, researchers have found. Researchers investigated the application of antimicrobial peptides (AMP) as substitutes for antibiotics in liquid sperm preservation. They were able to show that AMPs fight bacteria effectively in test tubes, and also that two of the investigated AMPs suppressed bacterial growth in liquid preserved semen preparations if combined with a small amount of the antibiotic "gentamicin....
