METHOD FOR INCREASING THE MILK YIELD OF RUMINANTS IN MILK AS WELL AS THE FAT AND LACTOSE CONTENT OF THEIR MILK

摘要

There is provided a method for enhancing the production of milk by lactating ruminants and increasing the milk fat and lactose content of the milk produced, by orally administering to lactating ruminants from about 50 to 150 mg per head per day of a glycopeptide antibiotic or polyether ionophore and in conjunction therewith, parenterally administering to said ruminants from about 5 to 50 mg per head per day of bovine somatotropin.
