Antibiotics are medicines that are given to people and animals to treat or prevent certain illnesses caused by bacteria.  Antibiotics either kill or hinder the growth of harmful bacteria in animals and people When treating farm animals against bacterial disease, antibiotics are most commonly administered in the same way as for humans – orally or by injection. Oral administration can include by bolus, tablet or paste, or as a powder or solution in feed or drinking water. The method of administration is usually a matter for the prescribing vet to determine, and will often depend on the species being treated, the  numbers needing treatment, and other factors such as the handling facilities available and the risk of stress for the animal. Stress is a major consideration as the animal being treated should be either clinically infected or at high risk of being infected at the time of treatment, and exposure to stress can further impair its immune system.


Antibiotics are given to animals that are sick, in order to help relieve the pain and distress due to the illness, help the animal feel better, and recover.  Antibiotics may also be given to animals that are in danger of becoming sick in order to prevent the illness or infection from happening in the first place.  Just like in people, however, antibiotics do not have any effect on diseases of animals that are caused by viruses or parasites, or other germs besides bacteria.  Some antibiotics, for reasons that aren’t totally understood, help cattle grow faster and get more out of the feed they eat.  These medicines are used at lower concentrations than when they are used to treat illness, and typically are included in the food that cattle eat.  The decision whether to use such products for this use (or any other reason) rests with the individual cattle raiser.  Not all of them choose to use antibiotics in this manner.  

We have antibiotics and sulfas in bolus, liquid, tablet, injectable and powder form. We carry Sav-A-Calf, Sulmet, Sustain III and Pennchlor for cattle. Treat swine dysentery, scours and pneumonia with GentaMed, Agrimycin 343, SpectoGard and Terramycin scour tablets. Tylan and Lincomix can be used for poultry. Neomyein 32 prevents/treats scours in goats and sheep.

Features of Oral Antibiotics For Cattle

The oral administration of chlortetracycline, oxytetracycline, bacitracin, streptomycin and penicillin for the prevention of bloat in steers grazing Ladino clover has been investigated. Penicillin was the only antibiotic studied that prevented bloat when a single dose of 300 mg. or less was given. Single doses of 25 mg. of procaine penicillin gave good protection from bloat in yearling steers. Fifty mg. of procaine penicillin protected yearling steers in every case for 1.5- to 3-day periods. Older steers, weighing about 900 lb. required 50 to 75 mg. of procaine penicillin to prevent them from bloating. Clover consumption appeared to be slightly higher after penicillin treatment than before.

Potassium penicillin, in equivalent amounts, was equally as effective as procaine penicillin for the prevention of bloat. The nature of the procaine penicillin carrier and the concentration of the penicillin in the carrier appeared to have no effect. Penicillin had to be given several hours or overnight before it was effective in preventing bloat in steers that were bloating before treatment.
