To meet specific nutrient requirements, the per centage of nutrients in the diet for cattle is based on the quantities of forages and feeds consumed daily.
Cattle require certain amounts of certain nutrients every day, such as protein, calcium, and vitamin A. Daily dry matter intake of forage and feed is the amount of forage and feed (excluding the moisture content) consumed in a day. This publication includes nutrient requirement tables that report dry matter intake and average daily gain values. While specific requirements for forage or feed intake do not exist, estimates of how much forage or feed animals will consume is needed for diet formulation and prediction of animal performance. Mississippi State University Extension Service Publication 2484, “Mineral and Vitamin Nutrition for Beef Cattle,” outlines in detail calcium and phosphorus as well as other mineral and vitamin nutritional requirements of beef cattle. Mineral requirement values for calcium and phosphorus appear in this publication. Of the nutrients listed above, beef cattle need minerals and vitamins in the smallest quantities, but they are essential to health and productivity. Refer to Mississippi State University Extension Service Publication 2499, “Protein in Beef Cattle Diets,” for information on the role of protein in beef cattle diets. This publication contains a table of crude protein values. Protein is essential in beef cattle diets. Mississippi State University Extension Service Publication 2504, “Energy in Beef Cattle Diets,” contains a detailed discussion of beef cattle energy needs. This publication reports energy values for total digestible nutrients, net energy for maintenance, and net energy for gain. The second greatest need is energy, which is supplied by carbohydrates, fats, and protein. For more information on beef cattle water requirements, refer to Mississippi State University Extension Service Publication 2490, “Beef Cattle Water Requirements and Source Management.” Of these nutrients, they require water in the greatest amounts daily. Nutrients Required by Beef Cattleīeef cattle need water, protein, carbohydrates, fats, minerals, and vitamins. Body maintenance, reproduction, lactation,Īnd growth, says this Mississippi State University Extension report.Ĭan also impact nutritional requirements.
