In the United States, the sale of cattle for beef is the number one source of income to agriculture by a wide margin.
Most successful year around production of beef cattle usually depends upon the degree of attainment reached in meeting their day-to-day nutrient requirements.
Nutrition is an important modulator of immune function and can often tip the balance between health and disease.
Nutrition plays a key role in production success. In cattle, one of the most studied nutrition relationships is the effect of dietary energy and body energy reserves on postpartum breeding performance.
Feeding grain is common in feedlots. Corn or maize is the most prevalent followed by grain sorghum, barley and wheat.
Corn is a relatively abundant and inexpensive energy source containing approximately 70% starch.
In feedlot diets, calcium supplementation is required in all cases, owing to the low concentration of calcium in basal ingredients such as grain.
