Reduction of antibiotic usage and performance improvement following the use of a PCV2 vaccine
Is Version Of
The SafePork conference series began in 1996 to bring together international researchers, industry, and government agencies to discuss current Salmonella research and identify research needs pertaining to both pig and pork production. In subsequent years topics of research presented at these conferences expanded to include other chemical and biological hazards to pig and pork production.
There is growing concern about the use that is made of antibiotics in swine production, and a reduction of that use is perceived to be something that would be beneficial to the image of the industry. The use of antibiotics and the production performance were evaluated in seven finishing units of a production company before and after vaccination against porcine circovirus type 2 (PCV2) was implemented. A comparison was made for each single finishing unit to determine how vaccination of pigs with lngelvac CircoFLEX, a one-dose and 1 mL PCV2 vaccine, affected production. The piglets were vaccinated at weaning, and for each of the seven finishing units data on antibiotic cost, gain, feed conversion and mortality were tabulated for the batch before vaccination and the one after vaccination.
