Why do goats suddenly have muscle stiffness and fall?

 Goats can experience muscle stiffness and falling for a variety of reasons, and a proper diagnosis would require a veterinary examination. However, some common causes of muscle stiffness and falling in goats include:

Copper Deficiency: A lack of copper in the goat's diet can lead to a condition called swayback, where the goat's muscles become weak and stiff, and they may have difficulty walking.

Selenium Deficiency: Selenium is an essential mineral that goats need in their diet. A deficiency can cause muscle weakness and stiffness, which may result in falling.

Polioencephalomalacia: This is a neurological condition caused by thiamine deficiency, which can occur when goats consume too much sulfur in their diet. The condition can cause muscle stiffness and weakness, seizures, and falling.

Poisoning: Certain plants, chemicals, or medications can cause muscle stiffness and falling in goats. It's essential to keep toxic substances out of the reach of goats.

Injury: Trauma or injury to the spine or legs can cause muscle stiffness and difficulty walking or standing.

If you suspect that your goat is experiencing muscle stiffness and falling, it's essential to seek veterinary care as soon as possible. Your veterinarian can perform an examination and recommend appropriate treatment based on the underlying cause of the symptoms.
