Diet is a significant factor in the health and well-being of livestock. A balanced and nutritious diet can help in preventing various diseases, including cancer. Contaminants in feed, such as aflatoxins, have been linked to an increased risk of cancer in livestock. Therefore, it is essential to source high-quality feed and regularly test for contaminants. Additionally, incorporating natural antioxidants and phytochemicals in the diet may help in reducing cancer risk.
