By-product feed utilization by grazing cattle.
Supplementation of grazing cattle is a routine management practice that serves several purposes. It can be used to fill the gaps created by seasonal deficiencies in forage growth and quality. Supplementation can also extend pasture availability during drought, increase the carrying capacity of the pasture, and provide nutrients that are inadequate or missing in the forage. Supplementation can also be used effectively to dilute anti-quality factors present in certain forages. Locally available by-products of the grain and food-processing industries can provide a cost-effective source of nutrients to balance the nutritional needs of grazing cattle. It is expected that the availability and cost effectiveness of these feeds will only grow as cattle compete with the biofuels industry for grain in the future.
