Necropsy Procedures and Evaluation of Macroscopic Lesions of Pigs Infected with African Swine Fever Virus

Abstract: Necropsy Procedures and Evaluation of Macroscopic Lesions of Pigs Infected with African Swine Fever Virus

Pathology complements and provides a fundamental link to other disciplines for disease investigations supporting molecular biology, genetics, immunology, or virology as core basis of scientific research. Necropsies are an essential tool in veterinary pathology for disease investigation and should be conducted in a routine, systematic, and standard approach. An orderly necropsy procedure will allow the prosector (veterinary clinicians or veterinary pathologists) to determine macroscopically normal or altered structures and allow, through experience, to acquire dexterity, speed, and confidence in the technique. In conjunction with standardized macroscopic scoring protocols, necropsy is a powerful tool especially when using experimental animal models in research.

Video: Dr. Jay Johnson: Bioenergetics of Heat Stress in Sows

The Swine Health Blackbelt Podcast, Dr. Jay Johnson from the University of Missouri explores the bioenergetics of heat stress in gestating sows and how it affects growth and fat deposition. He discusses energy partitioning, thermoregulation, and genetic strategies to improve thermal tolerance without compromising productivity. Listen now on all major platforms!

"Gestating sows under heat stress grow faster than those in thermoneutral conditions, with much of that growth going into backfat."

Meet the guest: Dr. Jay Johnson earned his Ph.D. from Iowa State University and is now an Associate Professor of Animal Welfare and Stress Physiology at the University of Missouri. His research focuses on heat stress, swine productivity, and practical welfare innovations through physiology and genomics.
