1. A method of improving reproductive function of a ruminant comprising subcutaneously administering to the ruminant a veterinary composition comprising inactivated whole cells of Escherichia coli (E. coli), Trueperella pyogenes (T. pyogenes), Fusobacterium necrophorum (F. necrophorum), and F. necrophorum leukotoxin (LKT) protein, E. coli type 1 fimbrial adhesin (FimH) protein, and T. pyogenes pyolysin (PLO) protein, such that the reproductive function of the ruminant is improved, wherein the improving the reproductive function of the ruminant comprises reducing a calving-to-conception interval relative to a calving-to-conception interval of a control, wherein the control is a calving-to-conception interval from a ruminant that received an intravaginal administration of the veterinary composition.
