| Cornell Net Carbohydrate and Protein System (CNCPS) assumes that feedstuffs are composed of protein, carbohydrate, fat, ash, and water. Protein and carbohydrate DM are further subdivided by chemical composition, physical characteristics, ruminal degradation, and postruminal digestibility characteristics. This experiment was conducted to determine the protein and carbohydrate fractions of selected feedstuffs (Alfalfa, Corn silage, Wheat straw, Wheat bran, Barley, Soybean meal, Beet pulp, Fish meal, Cottonseed, and Cottonseed meals) for ruminants. The protein and carbohydrate fractions in feedstuffs revealed the fact that the fraction of non-protein nitrogen in forages and the fraction of soluble true protein in whole cottonseed as well as cottonseed meal were high. Soybean meal and barley contained a high quantity of insoluble true protein. The quantity of slowly degradable true protein in fishmeal and beet pulp was highest as compared to other feeds. Beet pulp, alfalfa hay, corn silage, and cottonseed meal contained a higher unavailable protein (fraction C) as compared to other feeds. Neutral detergent fiber (NDF) and acid detergent fiber (ADF) were highest in forages, beet pulp, wheat bran, and modest in cottonseed meals. Calculated non-structural carbohydrates (NSC) were highest in barley. | ||
