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.
