Stock Photo - ***AUGUST 19, 1971, FILE PHOTO*** The vaccine against viral gastritis and intestinal inflammation in piglets was developed by a team of scientists at the Research Institute of Veterinary Medicine in Brno, led by Jan Stepanek, Zdenek Pospisil, Ernest Mesaros, and Vaclav Rozkosny under the guidance of Jaromir Mensik. Viral gastroenteritis has been present in our country since 1965 and causes considerable damage in pig farms. The disease is quite different from other infectious diseases and requires regular maintenance of permanent immunity against the infection, which affects newborn piglets. The method of combating gastroenteritis has been proven in practice and in the farms where it has been used. Immediate vaccination ensures high immunity of all pregnant sows, which pass on protective substances in their milk to the piglets.
