Yes, sows can indeed develop a condition similar to milk fever, technically known as hypocalcemia.
Hypocalcemia in sows, often referred to as milk fever, occurs due to the high demand for calcium during milk production at and after farrowing (giving birth). Just like in dairy cattle, this sudden drain on calcium reserves can lead to a metabolic imbalance.
Causes of Hypocalcemia in Sows:
- High calcium demand: The rapid onset of lactation places a significant demand on the sow's calcium reserves.
- Dietary imbalance: Insufficient calcium or an imbalance of calcium, phosphorus, and vitamin D in the sow's diet can contribute to the problem.
- Age and parity: Older sows and those that have had multiple litters may be more susceptible.
Symptoms of Milk Fever in Sows:
While specific symptoms can vary, they often include:
- Muscle tremors
- Weakness
- Incoordination
- Inability to stand
- Convulsions
- Depression
- Loss of appetite
Prevention and Treatment:
- Balanced Ration: A well-balanced ration with adequate calcium, phosphorus, and vitamin D is crucial. Consult with a swine nutritionist to ensure proper dietary formulation.
- Calcium Supplementation: Some producers provide calcium supplementation around farrowing time. Products like Fresh-N-Easy™ (mentioned in the reference) are designed for this purpose and can be administered at farrowing and again 24 hours later.
- Veterinary Intervention: In severe cases, veterinary intervention is necessary. Veterinarians may administer intravenous calcium solutions to rapidly correct the calcium deficiency.
By ensuring proper nutrition and monitoring sows closely around farrowing, producers can significantly reduce the risk of hypocalcemia.
