Thus, in order to ensure optimal production at an economical cost, it is important to understand the factors involved in nutrient requirement estimates and adjust the diet formulation accordingly. Although these publications are extremely useful in formulation diets that meet the nutrient requirements of livestock used for food production, they can become outdated. Nutrient Requirements of the Mouse 4. Age Weight Illness Pregnancy Lactation Working Obesity Anorexia. We'll look at the balance of different macronutrients, as well as vitamins and minerals and their purpose in the body. These sugars can then be stored or used immediately to make energy needed for growth, repair, and to generate heat to keep warm. All animals, including both livestock and humans, need the correct amount of each to be healthy. All other trademarks and copyrights are the property of their respective owners. This begins with knowing the essential nutrients these small ruminants need—energy (fat and carbohydrates), protein, vitamins, minerals, water, and fiber—and their roles in growth, production, and reproduction Each report has been subjected to a rigorous and independent peer-review process and it represents the position of the National Academies on the statement of task. In terms of livestock, cattle have some of the greatest water requirements, with some cows needing up to 90 liters of water per day during hot summer months. Lactation Heavy lactation has greater nutrient demands than any other production state. Proteins are made of amino acids.
