Importance of vaccination against atrophic rhinitis in pigs on average daily gain and mortality rate

Abstract

The aim of this study was to investigate the effect of pigs, sows and piglets vaccination against atrophic rhinitis (AR) on the production results, the average daily gain (ADG) and mortality rate. Unvaccinated piglets, originating from vaccinated sows had a slightly higher ADG and only slightly less mortality than the control piglets (unvaccinated piglets and their mothers). Vaccinated piglets had a significantly higher (P<0.01) ADG and almost twice lower mortality rate than piglets unvaccinated, whether originating from vaccinated or unvaccinated mothers. Based on the observed results it is concluded that vaccination of pigs against AR significantly increases ADG and reduces mortality, and vaccination of sows against AR only slightly improves production performance and it is not economically justified for the studied farm.
