Warning: don't overuse DDGS for pigs
Pig producers should be careful not to overuse
DDGS for certain diets. That warning was given by Hans H. Stein of the
University of Illinois' Department of Animal Sciences.
Many pig producers have already taken advantage of the
availability of distillers dried grains and have incorporated DDGS into diets
fed to their animals.
While many producers successfully include 20%
DDGS in diets for all categories of pigs, Stein says in the February issue of North Carolina State University's Swine News that DDGS in finishing diets should be limited to 20% to limit the risk
of producing pork with soft bellies.
In diets fed to nursery pigs and
growing finishing pigs, however, as much as 35% DDGS can be
Stein also points out the importance of formulating all diets
including DDGS based on concentrations of digestible amino acids and digestible
phosphorus. DDGS sources that have a lysine-to-crude-protein ratio that is lower
than 2.80 should not be used in diets fed to pigs.
