(Table 8).
Lumpkins et al. (2004) evaluated DDGS as a feed ingredient
for broilers and concluded that DDGS can be
safely used at 6% of the diet in the starter phase and at
12 to 15% in the grower and finisher periods. However,
Lumpkins et al. (2004) speculated that when they fed
DDGS, the high level of dietary protein of corn origin
and the corresponding decrease in soybean protein may
have contributed to the depressed performance because
of a marginal Lys deficiency. This could have occurred
as their diets were formulated to maintain minimum
CP levels and on a total AA basis balanced for Met,
TSAA, and Lys only. In experiments 1 and 2, minimum
digestible AA were adjusted for constant ME levels.
Even chicks fed 24% DDGS had excellent growth performance
with an adequate digestible AA balance
