Feed is the single largest Expenditure with raising small ruminantsEstimated for 60% or more of total production costs. A balanced nutrition exerts a very large influence on flock reproduction, milk production, and lambs. Late-gestation and lactation are the most critical periods for ewe nutrition, with lactation placing the highest nutritional demands on ewes. Nutrition level largely determines growth rate in lambs . Lambs with higher growth potential have higher nutritional needs, especially with regards to protein. Animals receiving inadequate diets are more prone to disease and will fail to reach their genetic potential. Sheep require energy, protein, vitamins, minerals, fiber, and water. Energy (calories) is usually the most limiting nutrient, whereas protein is the most expensive. Deficiencies, excesses, and imbalances of vitamins and minerals can limit animal performance and lead to various health problems. Fiber (bulk) is necessary to maintain a healthy rumen environment and pr
