Cervical mucus on the tail of a cow
Keywords: estrus, mucus, management, bovine, dairy, detection
Dried cervical mucus on the tail of a cow. Sometimes this may be the only evidence of a mucus discharge in a cow. In some cattle it is very difficult to detect standing estrus; every possible cue must be taken into account. These include increased activity, decreased milk production, increased vocalizing, mucus discharges from the vulvar lips and after estrus, hemorrhagic metestral discharges.
