Abstract
A process for the production of a polyvalent vaccine effective in the prevention and treatment of mastitis in bovine animals is disclosed, which comprises periodically culturing the milk of animals exhibiting preclinical mastitis to cultivate any pathogens present therein, killing those pathogens and incorporating each strain of cultivated, killed pathogen in a pharmacological carrier together with all other strains previously identified. The process is repeated to ensure all newly appearing pathogenic strains are vaccinated against. The vaccine so produced has been demonstrated to be effective in reversal of hard udder syndrome.
