NEWS FEED & ADDITIVE MAGAZINE March 2025 21 AB Vista, a global animal nutrition technology company, will showcase how its gut health findings and nutritional solutions can support animal producers at VIV Asia 2025, taking place from 12-14 March at the IMPACT exhibition centre in Bangkok, Thailand. The company will host two technical seminars at the event, providing insights on key gut health biomarkers in monogastrics and the role of in-feed resin acids in improving animal performance and welfare. AB Vista’s Head of Global Technical, Dr. Gilson Gomes, will delve into the benefits of natural resin acids in animal production. Exploring the science behind infeed resin acids, he will examine how their use can support gut integrity and improve resilience and performance, naturally. Dr. Gomes will also share practical insights into application of Progres® - the first and only product in the animal feed market to leverage the power of natural resin acids. The seminar, “Progres: The science behind the use of resin acids to improve animal welfare and performance of animals”, will be on Wednesday 12 March at 1pm THA, in Jupiter 9. In a separate session, Global Services Manager Dr. Virginie Blanvillain will set out how AB Vista has successfully applied advanced microbiome analysis in the field.

The viral infection leads to reproductive disorder in sows and respiratory problems in infected newborn and growing pigs. Unfortunately, high genetic variability of the virus and differing disease-causing strength or virulence hinders vaccine development and complicates disease management. Not much is known of the factors contributing to viral disease severity or the anti-viral immune responses. But scientists from ChungAng University in Korea uncovered the impact of PRRSV on swine immunity. The scientists used single-cell RNA analysis to reveal key immune mechanisms in lungs of swine infected with PRRSV and revealed changes in immune cell composition in lungs during infection with PRRSV of varying severity. Dr. Jun-Mo Kim, Associate Professor at the Department of Animal Science and Technology, Chung-Ang University, Korea has focused his research efforts on filling this gap in understanding. “Using a PRRSV infection model, our goal is to advance the comprehensive understanding of the infection and response mechanism in order to minimize industrial damage,” shared Dr. Kim. Recently, his group analysed protein-coding RNA transcripts isolated from single cells and fluid collected from lungs of PRRSV-infected pigs. They monitored immune cell alterations triggered by PRRSV strains of varying virulence. This paper was made available online on January 28, 2025 and was published in Volume 16 Issue 1 of Nature Communications. Read more>> Korean scientists explore impact of PRRSV on swine immunity
