Besides these behaviours the dairy cows spend time ruminating, waiting to be milked, being milked, drinking and on social behaviours. This document is subject to copyright. [26] Leg injuries, muscle tears, or a massive infection of some sort may also be causes. The exact duration of sleep a dairy cow needs is unknown today.

[22] (Unlike horses, cows generally do not cooperate with a farrier when standing. [29] Post-mortem bloat also occurs because of gas formation inside the body. At the end of this project the scientists will also develop a more simple method to measure sleep on dairy farms without expensive equipment.

[12][13] Pliny said the same about the hind legs of an animal he called the achlis, which Pliny's 19th-century translators Bostock and Riley said was merely another name for the elk. Previous research has shown that if you prevent animals from eating and lying down they prioritize to lie down before eating. When done for medical purposes, this is often called "casting", and when performed without mechanical assistance requires the attachment of 30 to 40 ft (9.1 to 12.2 m) of rope around the body and legs of the animal. The owner of the cow commented that he had seen this happen "once or twice" before. The two major health problems in Swedish dairy production are mastitis and energy deficiency. By this calculation, at least 10 people would be needed to tip over a non-reacting cow.

Sometimes this occurs as a result of muscle and nerve damage from calving or a disease such as mastitis.
