MILK PRODUCTION FROM LACTATING RUMINANTS WHILE INCREASING MILK FAT AND LACTOSE CONTENT IN THE MILK PRODUCED

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.
