He was convicted along with Hitler in 1924 but continued to head the Oberland League until 1929.

In 1920 he became head of veterinary services in Germany.
In the 1890s, Ostertag started a rigorous program of meat inspection in Berlin, and he was referred to as the "Father of Veterinary Meat Inspection" in Germany. Ostertag's meat inspection act of 1900 greatly reduced incidences of bovine tuberculosis in human beings.
He was the author of numerous publications in veterinary science, and is remembered for his influential Lehrbuch für Fleischbeschauer ("Handbook of Meat Inspection"), a book that was later translated into English.
His name is lent to Ostertagia, a genus of attenuated nematodes of the family Trichostrongylidae. These organisms are found in cysts on the wall of the abomasum of cattle and other ruminants. The disease associated with the organism is called "ostertagiosis".
