How is rabies vaccine made horse?
Healthy horses are immunized with a rabies vaccine. Crude plasma is collected and immunoglobulin is converted into F(ab)2 fragments by pepsin digestion. The F(ab)2 fragments are purified using caprylic acid precipitation followed by ultrafiltration.
What do they inject horses with before races?
furosemide
Many people use furosemide (Salix, Lasix) routinely to help prevent bleeding in horses suffering from EIPH (Exercise Induced Pulmonary Hemorrhage). In most cases, a dose of furosemide is given and water is withheld at least 4 hours before competition in order to prevent bleeding.
