Cow Reluctant to Rise: Causes, Down-Cow Risks & What to Do

A cow may be reluctant to rise because she is weak, painful, neurologically impaired, or systemically ill. Around calving, some of the most common causes are hypocalcemia (milk fever), other electrolyte or mineral problems such as low magnesium or low phosphorus, and calving-related nerve or muscle injury. Merck notes that secondary recumbency is especially common in dairy cows during the periparturient period, often after hypocalcemia or calving paralysis that did not fully respond to treatment.

Calving paralysis can happen after a difficult birth when pressure inside the pelvis injures the sciatic or obturator nerves. These cows may knuckle at the fetlock, splay the hind legs, or do the splits when trying to stand. Trauma, fractures, hip dislocation, severe foot pain, and muscle tears can also make rising difficult.

Serious infections are another major cause. Severe mastitis can lead to shock and weakness. Acute puerperal metritis after calving can cause toxemia, fever, depression, and recumbency. In late pregnancy, poor energy balance can contribute to pregnancy toxemia, especially in cows carrying twins or eating poorly.

Once a cow has been down for many hours, the original problem is only part of the picture. Pressure on muscles and nerves can create a second wave of injury, making it harder to stand even after the first cause is treated. That is why early veterinary care matters so much.

See your vet immediately if the cow cannot rise, is breathing hard, is bloated, seems dull, has a cold body or ears, has a fever, recently calved, has a swollen painful udder, foul-smelling discharge, obvious trauma, severe lameness, or keeps trying and failing to stand. A cow that is laterally recumbent, not eating, or getting weaker should be treated as an emergency.

Short-term monitoring at home may be reasonable only while you are arranging veterinary care and only if the cow is bright, eating, drinking, and able to shift position. Merck notes that recovery is still possible in alert down cows that continue to eat and drink, but prognosis becomes poor if there is no improvement after correction of electrolyte problems and several days of proper nursing care.

Do not wait to "see if she gets up tomorrow" if she has been down for hours, especially after calving. Secondary muscle and nerve damage can begin quickly. The longer she remains recumbent, the harder recovery becomes.

If transport is being considered, ask your vet first. In the United States, nonambulatory disabled cattle are automatically condemned for the human food supply, and moving a down cow without a clear veterinary plan can create both welfare and legal problems.

Your vet will start with a focused history and physical exam. Important clues include whether the cow recently calved, how long she has been down, whether she was treated already, what she is eating, and whether there was a difficult birth, trauma, mastitis, or uterine discharge. The exam often includes temperature, heart rate, hydration, udder and uterus check, limb and hip evaluation, nerve function, and whether she can make coordinated attempts to rise.

Depending on the findings, your vet may treat likely reversible causes right away. That can include calcium for suspected milk fever, fluids, anti-inflammatory medication, treatment for severe mastitis or metritis, and careful nursing instructions. If calving paralysis is suspected, Merck recommends early transfer to an area with good footing and measures to prevent the hind limbs from splaying too far apart.

Diagnostics may include bloodwork for calcium, magnesium, phosphorus, energy balance, and dehydration; milk or uterine evaluation; and assessment for fractures, dislocations, or severe soft tissue injury. In some cases, your vet may recommend lifting assistance, hip lifters used carefully, or referral for intensive nursing.

Your vet will also talk with you about prognosis. Cows that remain bright, eat, drink, and keep trying may recover with time and nursing care. Cows that become listless, develop pressure sores, stop eating, or fail to improve after several days have a much more guarded outlook, and humane euthanasia may become the kindest option.

While waiting for your vet, place the cow on deep, dry, well-bedded footing and keep her chest upright in a sternal position if possible. This helps reduce bloat risk and makes breathing easier. Keep hay and fresh water within easy reach. If she recently calved, note the time of calving, whether the birth was difficult, and whether there is abnormal discharge, udder swelling, or a cold, weak appearance.

Turn her regularly if she cannot reposition herself. Check for swelling, abrasions, manure scald, and pressure sores over the hips, hocks, and shoulders. Keep the area quiet and non-slip. If she tries to rise, make sure the footing is secure so the hind legs do not slide apart.

Do not drag her by the head, horns, neck, or limbs. Do not force repeated lifting attempts without veterinary guidance, because that can worsen muscle, nerve, or hip injury. Hip lifters and slings can help in selected cases, but poor technique can also cause harm.

If your vet gives a nursing plan, follow it closely and keep notes on appetite, water intake, manure, urination, attitude, and attempts to stand. If she becomes dull, stops eating, develops bloat, lies flat out, or shows skin sores, contact your vet again right away.
