Investigations were performed concerning the effective therapy of Metrisan
AN, composed of: ampicilline, neomycine and substances which increase the p
hagocytic activity of granulocytes during MMA syndrome in swine. It was dem
onstrated that the curative activity of Metrisan AN was expressed by a more
rapid cessation of discharge from the genital tract and restoration to the
normal secretion of milk within 24-48 hours after intrauterus infusion of
that preparation. The application of Metrisan AN into the uterus was also p
rofitable to the pigs' fertility. Piglets born to sick sows who had intraut
erus Metrisan AN applied were characterized by higher weight 35 days after
birth, a lower percentage of diarrhoeal in their litter as well as a lower
mortality.
