Milk fever is a nutritional disease affecting sheep and goats during lactation due to a lack of what in the blood?

Iron
Protein
Calcium
Magnesium

The correct answer is: Calcium

Milk fever is a condition that primarily occurs in lactating animals, particularly in sheep and goats, due to low levels of calcium in the blood. During lactation, the demand for calcium significantly increases as it is essential for milk production. A shortage in calcium levels can lead to muscle weakness, reduced milk yield, and in severe cases, it can result in collapse or even death. The biological mechanism revolves around the body's ability to mobilize calcium from the bones or dietary sources. When lactating animals do not receive sufficient calcium in their diet prior to and during lactation, they may not be able to adequately respond to the increased calcium demand, thus leading to milk fever. Therefore, ensuring an adequate intake of calcium during this period is critical for the health and productivity of lactating sheep and goats.
