Postpartum paresis in cows is a complex and life-threatening animal disease, which is characterized by a sharp decrease in calcium. Occurs in the first 72 hours after calving. Why and how to prevent illness, let's find out together.
What kind of disease and how does it occur?
Postpartum paresis most often occurs in high-yielding or aged cows, the disease is rarely found in young heifers. The sick cow has lost its appetite in the first days of calving, it develops nervousness, muscle spasms appear, and body temperature drops. If in time the animal does not begin to heal, the partial paralysis of the cow overcomes the cow and it falls with its head thrown back. This is a very dangerous stage of the disease, in 70% of cases without timely treatment the animal dies.
Symptoms of postpartum paresis:
- appetite is lost, there is no chewing gum;
- body tremors appear, the temperature drops;
- instability in the legs, muscle spasms, paralysis;

- depression of the condition, lacrimation;
- termination of the internal secretion, including emptying.
Today, among specialists there are several explanations for why this complex disease occurs. The first option is a sharp decrease in blood sugar, hypoglycemia. The second option is enhanced activity of the pancreas, resulting in a large amount of insulin. In connection with these opinions and confirmations in practice, one of the fastest methods of treating the problem is to inject 40 ml of a 20% glucose solution. However, there are other causes of birth paresis:
- overfeeding with concentrates;
- long keeping of an animal without walking;
- cold and draft during calving;

- Air inflating is performed from the lower nipples with the device. Air injection is stopped after the voltage of the udder.
- Then nipples are tied up with a ribbon or a bandage. You can not use thread or rope, they can deaden the fabric udder.
- Dressing with the nipples can be removed immediately after the animal gets up. See the video for more details.
Another method of treatment is to inject a glucose solution into a vein. Apply 250-500 ml of calcium gluconate solution. After immediate treatment, as a rule, the cow gets up on its feet within 30 minutes. In this case, the animal invigorates, takes to food, renews the gum, goes to the toilet. If the cow does not get up within the first hours after the treatment, the therapeutic measures should be repeated.
