Alternative or non-conventional feeds, such as grain screenings, cull potatoes or distillers’ grains, can be an economical means for beef cattle producers to supplement forage and grain inventories while continuing to meet animal nutritional requirements. However, due to variability in the supply, nutrient composition and quality of these feed ingredients, there can be pitfalls if not properly managed. Below are several key areas that producers can focus on when deciding if alternative feeds are a good fit for their farm.
Match feed composition to beef cattle groups
Two of the main components to creating a balanced ration for beef cattle is knowing the nutritional composition of the feedstuffs being used and their suitability for the type or group of cattle being fed. Ration-balancing tools, such as CowBytes, allow producers to input feed analysis results and ingredient costs to calculate appropriate rations that safely use alternative feeds and reduce the risk of digestive upsets.
Screenings from cereals, pulses or canola, can be cost-effective sources of protein and energy in the diet for mature cattle. However, inconsistency between loads and the potential for toxins requires feed testing to determine the true nutritional value. In comparison, soyhulls or beet pulp, which are byproducts of processing, typically contain a consistent amount of energy due to having a high level of digestible fiber. This makes them an excellent feed for most classes of cattle.
