DRIED DISTILLERS' GRAINS WITH SOYBLES
FOR GROWING-FINISHING PI S JUN 2 1972

G. E. Combs and H. D. Wal ace -

liF.A.8, Univ, of Florida
Dried distillers' grains with: solubles (DDG/S) .di nciMiCT ,ir-a_ Al"y ; fluence
rate or efficiency of gain when included in starter diets at levels of 10 or 20%
(Fla. Ani. Sci..Mimeo. Series No. 69-14).

The present study was initiated to study the effects of DDG/S upon growth
performance and nutrient digestibility when added to the diets of growing-finishing
swine.

Experimental.

Eighteen pigs averaging 51 lb. were allotted to three treatments from outcome
groups. The treatments'were diets containing 0, 10 and 20% DDG/S (table 1). The
pigs were group-fed in concrete-floored pens for a period of 73 days. Feed and
water were available ad l1bitum. When the animals weighed about 100 lb. and again
at the termination of the experiment, digestibility of dry matter, protein and
ether extract was determined.

Results and Discussion

The results are summarized in table 2. .

Daily gains were not significantly affected by the addition of either 10% or
29% DDG/S. Daily feed consumption tended to increase with increasing levels of
DDG/S. The pigs fed the 10 and 20% DDG/S diets consumed 7% and 14% more feed than
those given 0% DDG/S. This increase in consumption may be a reflection of the
decrease in digestibility of dry matter protein and ether extract. During both
phase 1 and phase 2 the pigs fed 20% DDG/S had the lowest digestion coefficients
followed by the 10% DDG/S group and the highest being found with the group fed 0%
DDG/S. These data would suggest that with"DDG/S apparently depressing nutrient
digestibility an increase in feed consumption must occur in order to maintain equal
weight gains among the treatments.

'. *. Summary ..

Growing-finishing pigs (initial weight, 51 lb.) were fed diets containing 0,
10 or 20% dried distillers' grains with solubles. Daily gain, feed consumption and
feed efficiency were not significantly (P < .05) influenced by treatment. But there
was a definite trend of increased feed consumption with increasing levels of distilled
grains. Digestibility of dry matter, protein and ether extract was significantly
(P < .05) influenced by dietary level of distillers grains. In general the degree of
depression in digestibility was correlated with the dietary level of dried distillers
grains with solubles.
