Evaluation of transmammary-delivered firocoxib and a vapocoolant spray to alleviate pain in piglets after surgical castration and tail docking
January 20, 2023By Abbie V. Viscardi, PhD
This study aimed to assess a novel strategy for pain management of piglets after routine processing procedures. By providing the sow an analgesic drug that is able to cross the blood-milk barrier in the mammary gland, nursing piglets can be noninvasively provided pain relief transmammary prior to surgical castration and tail docking.

An African Swine Fever (ASF) positive cohort study: Validating various PCR tests and sample types for African Swine Fever Virus (ASFV) detection in boars; and determining the possibility of transmission via artificial insemination
October 29, 2022By Dr. Darwin Reicks
The first study using experimentally ASFV inoculated adult, commercial boars to determine which sample types and PCR procedures were optimum in detecting ASFV in boars and gilts. Additionally, it proved that insemination of ASFV infected semen to naïve gilts resulted in transmission of the virus.

Refinement of water-based foam procedures for the depopulation of swine
October 20, 2022By Andrew Bowman
• During extraordinary circumstances, it may become necessary to depopulate large populations of swine as a disease containment measure. Depopulation methods currently recommended or recommended under constrained circumstances for swine by the AVMA present significant logistical challenges when scaled to large populations or performed in field conditions.
