A Holstein cow in her third lactation, approximately three months post-calving, is unable to stand. The history indicates that the animal was milked normally the previous evening with no apparent issues, but failed to stand this morning despite numerous attempts. Upon examination, the animal is in sternal recumbency; displacement of the corn stalks in the bedding from attempts to stand is evident.
Sunken eyes, tachypnea, tachycardia, temperature 104.5 °F (40.3 °C).
