The concentrate is another type of animal feed. It is rich in carbohydrates, proteins and digestible nutrient content. But it has a low amount of fibre. Basically, concentrate consists of fat, cereal grains and their by-products (barley, corn, oats, rye, wheat), high-protein oil meals or cakes (soybean, canola, cottonseed, peanut), and by-products from the processing of sugar beets, sugarcane, animals, and fish.Due to this composition, concentrate provides more energy to animals.
