Macrominerals required include calcium, magnesium, phosphorus, potassium, sodium, chlorine and sulfur. The microminerals required are chromium, cobalt, copper, iodine, iron, manga- nese, molybdenum, nickel, selenium and zinc.
animal allows cattle to turn non-protein sources of nitrogen such as urea into protein. The young growing animals requirement for protein is high and this demand decreases with age. Requirements for protein are usually secondary to that for energy, however they are closely linked.
Phosphorus. Cows that produce more milk, and milk with more fat and protein, will have higher nutrient requirements. Growth. Requirements for growth are determined by actual weight, average daily gain (growth rate), weight at maturity, and composition of gain. Composition of gain simply means whether cattle are putting on more muscle or more fat.
Pasture forages for beef cattle can be roughly divided into five categories—warm-season perennials, warm-sea-son annuals, cool-season perennials, cool-season annuals and legumes for pastures.
Each of these forage types can meet the nutritional requirements of beef cattle when they are at their peak production (Figure 1).File Size: KB.

Feed Requirements. Beef cattle will have varying requirements depending on their age and stage of production.
Calves will need a higher level of nutrition to allow for their growth, while mature dry cows will need a relatively low level of nutrition. Pregnant cows in the last third of pregnancy require more nutrients than dry cows. PROTEIN The total diet should average around 11% to 13% crude protein (CP) for most uses.
Younger, growing animals need more protein. Some feeders use a ration of around 12% CP throughout the feeding period. Others prefer to feed more protein for starting and less to older, finishing cattle.
