What disorder may result from a lack of proper nutrition in animals?

1. Toxoplasmosis

2. Encephalitis

3. Grass Tetany

4. Leptospirosis

The correct answer is: Grass Tetany

Grass Tetany, which results from a lack of proper nutrition, particularly a deficiency in magnesium, is indeed the correct answer. This condition often occurs in grazing animals, such as cattle and sheep, when they consume large amounts of lush grass that is low in magnesium. The imbalance can lead to severe metabolic disturbances, affecting the animal's nerve and muscle function. Signs of Grass Tetany can include muscle tremors, seizures, and in severe cases, death. Proper nutrition is crucial for maintaining electrolyte balance and preventing the onset of such metabolic disorders. In contrast, the other disorders listed—Toxoplasmosis, Encephalitis, and Leptospirosis—are primarily caused by infectious agents (parasites, viruses, and bacteria, respectively) rather than nutritional deficiencies. Understanding the role of nutrition in animal health is essential for preventing conditions like Grass Tetany and ensuring the overall well-being of livestock.
