Cattle in some parts of the world graze pastures that consist of tall fescue that may contain ergot alkaloid contamination. Those ergot alkaloids are associated with reduced reproductive rates in cattle. Our objective was to determine if ergot alkalo

Osteopontin (OPN) is a protein found at higher concentrations in the seminal plasma of bulls with above average fertility. Polymorphisms have been reported within the OPN gene promoter that can affect production of this protein and thus, affect ferti
