Rapid treatment after a down cow has been correctly diagnosed, followed by nursing at a high standard, maximises the cow’s chance of recovery.
If the cow is not helped to get back on her feet quickly and given good, consistent care, secondary damage to muscles and nerves in the leg she is lying on can occur quickly (within three to six hours). This damage becomes the reason she is unable to rise, regardless of the original cause of her going down.
Careful mineral supplementation, good springer management, and accurate body condition scoring can all help prevent cows from going down. See the DairyNZ website for more information on body condition scoring dairynz.co.nz/bcs
There are many causes of down cows, including calving paralysis, metabolic disease, other infections, gut diseases, injury and previous illnesses.
DairyNZ Animal Husbandry Specialist, Anna Irwin, says one of the crucial early decisions is whether to persist with treatment or humanely euthanase the cow. “If a down cow cannot be nursed with a high standard of care it is better for the cow’s welfare that she is euthanased within a short time as her chances of recovery will be low.”
If a down cow is drowsy, depressed and non-responsive, an immediate diagnosis should be made to determine whether treatment is an option. If she is still alert, treatment should begin as quickly as possible. In some cases, a cow may recover on the same day. If it’s looking like it will take longer, she should be moved to a dedicated nursing area.
If the cow cannot stand on her own within 48 hours of going down, you should seek veterinary advice.
Down cows should be a priority no matter what else is happening on-farm. The management of all down cows should include:
Note which leg the cow is sitting on each time she is checked. If the cow cannot swap sides by herself, she must be rolled frequently onto her other side, especially if she is trying to stand up.
Hip lifters should only be used to assist a cow into a standing position, not to suspend a cow that is unable to stand without the additional support of a breast strap or sling.
It is acceptable to move a cow a short distance using a sling or breast strap, with a correctly applied hip clamp, as long as it doesn’t cause the cow any undue discomfort or distress. If you need to move a cow longer distances, use a transport tray, tandem trailer or front end loader bucket.

If the cow is still down after four days, a re-assessment should be made of whether it is worth continuing treatment. Some cows, with careful care, can take a week to recover.
A detailed plan outlining down cow management on your farm will improve your chances of success. We encourage you to have an established process for making decisions about the diagnosis, treatment and care of down cows, including when to call a vet for assistance.
