Experiment 1 provided an indication that 15% DDGS
could be used in practical starter diets. The objective of
experiment 2was to examine the effects ofDDGS on broiler
performance and carcass yield through market weight.
Graded levels of DDGS up to and exceeding 15% were
evaluated in a 42-d broiler growth study. Six replications
per treatment of 50 straight run Cobb × Cobb-500 chicks
per pen were housed in a curtain side building. The house
had litter floors and the pens were separated by wire mesh
to create 2.4 × 3.7 m (8 × 12 ft) pens. Each pen contained
2 bell waterers and 2 galvanized steel feeders. Feed and
water were provided ad libitum throughout the study.
Four experimental diets containing 0, 6, 12, and 18% DDGS
were formulated for the starter (0 to 16 d), grower (17 to
31 d), and finisher (32 to 42 d) periods (Table 3).
