Which vital nutrient is often supplemented in high-production dairy cattle feeds?

Calcium is a vital nutrient that is frequently supplemented in high-production dairy cattle feeds due to its significant role in various physiological functions. One of the primary reasons for this supplementation is to support strong bone structure and adequate milk production. Dairy cattle, especially high-producing ones, have increased calcium requirements due to the calcium they lose in milk.

When cows are in the lactation phase, the demand for calcium spikes considerably; it is crucial for effective muscle contraction and the overall functioning of the dairy cow's physiology. A deficiency in calcium during lactation can lead to conditions such as milk fever (hypocalcemia), which can severely impact both the health of the cow and her milk yield.

Furthermore, adequate calcium levels help maintain proper metabolic health and can support immune function, thereby improving overall productivity and longevity in dairy herds. The supplementation of calcium thus assists in ensuring that high-production dairy cattle can meet their increased nutritional needs effectively.
