Which of the following strategies is effective in preventing nutritional deficiencies in livestock?

Mineral supplementation is a key strategy for preventing nutritional deficiencies in livestock because it ensures that animals receive essential vitamins and minerals that may not be sufficiently available in their regular diet. Many livestock species have specific mineral requirements that need to be met for optimal health, growth, and reproduction. By providing supplements tailored to their needs, producers can address potential deficiencies that could arise from inadequate forage or variations in soil mineral content.

For example, if a grazing area is low in selenium or calcium, supplementation can directly address these shortfalls and help maintain the overall health of the herd. Additionally, mineral supplementation can improve immune function, support productive efficiency, and enhance overall livestock performance.

In contrast, while increased grazing time might contribute positively to nutrient intake, it does not guarantee that animals will receive balanced nutrition, especially if the forage quality is poor. The elimination of grains from the diet can limit energy supply and essential nutrients that grains typically provide, potentially leading to deficiencies. Likewise, feeding the same forage year-round can lead to a lack of dietary variety, which may result in specific nutrient deficiencies, making it an inadequate strategy for comprehensive nutrition management. Therefore, mineral supplementation stands out as a proactive approach to ensure that all nutritional needs are adequately met throughout various stages of livestock growth and production
