Model predicts effectiveness of livestock vaccines

Scientists at The Roslin Institute have developed an epidemiological model to investigate the effectiveness of vaccines for preventing, mitigating or eliminating infectious diseases in livestock. When appropriately applied, even imperfect vaccines can prevent, eliminate or largely reduce the prevalence of viruses, the model shows. The goal of effective vaccination is not only to protect individuals […]

PRRSV: strains of low and high virulence compared

A research group from the University of Córdoba, led by Professor Librado Carrasco, has been researching Porcine reproductive and respiratory syndrome virus (PRRSV) for years, with the aim of developing effective vaccines. Although PRRSV was discovered in the 1990s, in recent years more virulent strains have emerged. As each strain behaves differently, developing effective vaccines […]

Feed additives may help stop the spread of viral diseases in pigs

Initial results of a study conducted by Pipestone Applied Research, finds that five commercially available feed additives may stop the spread of porcine reproductive and respiratory syndrome (PRRS), porcine epidemic diarrhea (PED) and Seneca Valley A (SVA) through contaminated feed. Dr. Scott Dee, Research Director at Pipestone Applied Research, presented the results of the first […]
