Porcilis Porcoli Diluvac Forte (vaccine to provide passive immunity to the progeny against E. coli in pigs) is a vaccine used in sows and gilts to reduce mortality and clinical signs which can be caused by enterotoxicosis in piglets during their first days of life. Stimulates the sow's immune system to produce antibodies against these strains, which she passes on to her piglets through colostrum (first milk).
