Since the VFD (Veterinary Feed Directive) came into effect on January 1, 2017, livestock producers have been implementing changes required for use of most antibiotics when delivered in feed or water (injectables are not affected). Included in these changes, feed distributors are now required to have a valid VFD, written by the prescribing veterinarian, in order to prepare antibiotic-medicated feeds. This requires additional paperwork that could, in some instances, delay a producer’s response to a disease outbreak. As new livestock barns are being built, particularly in the swine sector, many producers have incorporated medicators into their water systems. This technology, when used to deliver antibiotics, bypasses the feed mill formulation step and can facilitate rapid mass treatment of herds during a viral or bacterial disease outbreak. Several antibiotics commonly used in pigs can be administered in water.
Antibiotics and medications are critical to treat, control, and prevent disease in swine. Without the responsible and timely use of antibiotics, sickness can spread rapidly on a farm, endangering the health and welfare of animals and the safety of our food. While pig farmers work closely with veterinarians to ensure that their pigs stay healthy, at times pigs need medical attention requiring the use of antibiotics to treat illness.
When farmers use antibiotics as prescribed by a veterinarian, pigs tend to give birth to healthier litters, get sick less often and recover faster, and suffer less premature death due to illness. Combining the responsible use of antibiotics along with strict biosecurity measures is very effective in maintaining pig health and maximizing production and profits. Pipevet.Com carries the majority of prescription and non-prescription antibiotics for swine use. If you have any questions please feel free to contact us for answers.
Features of Medication For Pigs
Medicines are administered in a variety of ways depending on the type of medicine and its availability. Some medicines are toxic by injection and may only be available by mouth, whereas others may be applied and absorbed through the skin. It takes a period of time for any medicine to be absorbed into the system to reach levels sufficient to have a therapeutic effect and then be excreted from the body. The frequency of treatment is determined using this knowledge.
The following methods of administration are used in the pig :-
By injection – Intravenous, subcutaneous, intradermal and intramuscular.
Topical – The medicine is applied to the surface of the body. An example would be the use of pour-on organophosphorus preparations or sprays for the control of mange.
Oral – Most injectable antibiotics are also available for oral administration.
Via the Uterus – Pessaries (small slow-melting tablets) can be placed into the uterus following interference at farrowing. Likewise, antibiotics can be deposited into the anterior vagina in cases of infection.
Via the Rectum – This is not a normal method for administrations in the pig, although in cases of meningitis associated with salt poisoning and water deprivation, water can be dripped into the rectum to correct the imbalance. (See chapter 15 Flutter valve)
The method of administration will be indicated on the label of the bottle, and this should always be followed. For example, intravenous injections are used for anaesthesia, intradermal injections to test animals for tuberculosis, and subcutaneous injections for certain types of antibiotics or some vaccines. The most common route of injection however is intramuscular for antibiotics, iron injections, and oil-based vaccines. Occasionally, injections might be given into the joint for arthritis or into the mammary glands for mastitis.
Types of Medication For Pigs
Medicines used in the swine industry can be grouped into eight broad areas:-
Antibiotics and antibacterial substances.
Minerals, for example iron, vitamins and electrolytes.
