While fiber limits the energy value of plants for monogastric animals, ruminants are capable of utilizing fiber as a source of energy in their diet.
Minerals
Minerals are essential for the structure, metabolic, and immune functions of livestock animals. They are classified into macro minerals, which are required in larger amounts, and minor minerals, which are needed in smaller quantities. Providing the right balance of minerals in the diet is crucial for maintaining the overall health and well-being of the animals.
Vitamins
Vitamins play a significant role in the physiological functions of livestock animals, serving as coenzymes for metabolic processes and antioxidants that help prevent cell damage. Livestock animals require both fat-soluble and water-soluble vitamins in their diet. While some vitamins can be synthesized by the animals themselves or obtained from sunlight, it is important to ensure that their diet includes an adequate amount of essential vitamins.
Overall, providing a balanced ration that includes the right proportions of protein, energy, fiber, minerals, and vitamins is essential for meeting the specific nutrient requirements of livestock animals. Proper nutrition plays a critical role in maintaining their health and supporting their productivity.
