Insights into genetic determinants of piglet survival during a PRRSV outbreak.

Breeding animals to produce more robust and disease-resistant pig populations becomes a complementary strategy to the more conventional methods of biosecurity and vaccination. The objective of this study was to explore the ability of a panel of genetic markers and immunity parameters to predict the survival rates during a natural PRRSV outbreak. Ten-week-old female Duroc pigs (n = 129), obtained from 61 sows and 20 boars, were naturally infected with a highly pathogenic PRRSV genotype 1 strain.

Gut microbiome and resistome characterization of pigs treated with commonly used post-weaning diarrhea treatments.

Background: The global burden of antimicrobial resistance demands additional measures to ensure the sustainable and conscious use of antimicrobials. For the swine industry, the post-weaning period is critical and for many years, antimicrobials have been the most effective strategy to control and treat post-weaning related infections. Among them, post-weaning diarrhea causes vast economic losses, as it severely compromises piglets' health and growth performance.

Safety for the environment of a feed additive consisting of semduramicin sodium (Aviax 5%) for chickens for fattening (Phibro Animal Health s.a.).

Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety for the environment of the coccidiostat semduramicin sodium (Aviax 5%) when used in feed for chickens for fattening. The additive Aviax 5% is intended to be used as a coccidiostat in feed for chickens for fattening at a level of 20-25 mg semduramicin sodium/ kg complete feed. The safety and efficacy of the additive was evaluated by the FEEDAP Panel in 2018 and 2022.
