A finishing study was conducted to determine the value of the fiber in distillers grains plus solubles on cattle performance. Five treatments were evaluated: a corn control diet, 20 or 40% modified distillers grains plus solubles, plus two diets containing corn germ meal and corn bran balanced to equal the fiber content of the two modified distillers grains plus solubles diets. Th ere was a significant improvement in ADG and F:G for cattle fed modified distillers grains plus solubles compared to control. Cattle fed the corn germ meal and bran diets had increased DMI, slightly lower ADG, and poorer F:G compared to the control. Th e isolated fiber component had 83– 90% the feeding value of corn, while modified distillers grains plus solubles had 107– 108%. Other components in distillers besides fiber must improve the value of distillers compared to corn

the wet milling industry. Likewise, the 
40FIB treatment was formulated to mimic 
40MDGS by adding 3% SEM and 14% 
wet corn bran. On a DM basis, all diets 
contained 12% high moisture corn (HMC), 
8% corn silage, 3% alfalfa hay, and supple-
ment fed at either 5% or 8%. Th e control, 
20FIB, and 40FIB had a greater inclusion of 
supplement because 3% soybean meal was 
fed in addition to urea as a RDP source. Th e 
supplement also provided Tylan- 40® (Elan-
co Animal Health) at 90 mg per steer daily 
and Rumensin- 90® (Elanco Animal Health) 
at 30 g per ton DM.
Blocks 1, 2, and 3 were implanted with 
Revalor- 200 99 days prior to harvest and 
block 4 was implanted 113 days prior to 
harvest. Cattle in the three heavier blocks 
were fed for 134 days and the light block 
was on feed for 148 days. Steers were 
shipped to Greater Omaha for slaughter, 
and carcass data were recorded. On day of 
harvest, hot carcass weight and liver score 
were collected. Following a 48- hour chill, 
USDA marbling score, LM area, and 12th rib 
fat thickness were recorded. Animal perfor-
mance and carcass characteristics were an-
alyzed as an unstructured treatment design 
using a protected F- test, where block was 
included as a fi xed eff ect. Treatment design 
was also analyzed as a 2x2+1 with two feed 
sources (MDGS or Fiber) and two inclusion 
levels (20 or 40%) plus a control. Inter-
actions for the 2x2 factorial design were 
evaluated. Linear and quadratic orthogonal 
contrasts were used to evaluate inclusion of 
MDGS or fi ber in the diet with the control 
being the 0% inclusion level. Data were 
analyzed using the MIXED procedure of 
SAS (SAS Institute, Inc. Cary, N.C.), where 
pen was the experimental unit. Treatment 
diff erences were declared signifi cant at P ≤ 
0.05. One steer from the control treat-
ment died on day 147 and a steer from the

study (2016 Nebraska Beef Cattle Report, 
pp. 122– 23). A diff erent experiment con-
cluded that feeding individual components 
did not mimic performance of WDGS, but 
including fi ber, protein, fat and solubles 
combined together gave the same perfor-
mance as feeding WDGS (2016 Nebraska 
Beef Cattle Report, pp. 124– 127). Th ese 
fi ndings demonstrate that the interactions 
between fi ber, protein, fat, and solubles in 
WDGS are important, and have a similar 
feeding value to WDGS. Th e objective of 
this study was to determine the value of 
the fi ber in modifi ed distillers grains plus 
solubles for fi nishing cattle performance.
Procedure
A fi nishing experiment conducted at the 
Eastern Nebraska Research and Extension 
Center utilized 800 crossbred yearling 
steers (initial BW = 915 lb ± 53 lb). For fi ve 
days before the beginning of the trial, cattle 
were limit- fed a diet of 50% alfalfa and 50% 
Sweet Bran (DM Basis) at 2% of BW to re-
duce variation in gastrointestinal fi ll. Cattle 
were weighed on day 0 and 1 to establish 
an accurate initial BW. Steers were split into 
four blocks according to their initial BW 
with each block consisting of 200 head. A 
total of 100 pens were used on the study 
with 8 steers per pen. Pens were assigned 
randomly to treatment with fi ve treatments 
and 20 pens per treatment. All cattle were 
adapted to the fi nishing treatments over a 
fi ve step adaptation process by replacing 
alfalfa with dry- rolled- corn (DRC).
Th e fi ve treatments consisted of a corn 
control diet (CON), 20% (20MDGS) or 
40% (40MDGS) modifi ed distillers grains 
plus solubles (MDGS), plus two diets 
formulated with corn germ meal and corn 
bran to equal the fi ber content of the two 
MDGS diets (20FIB and 40FIB; Table 1). 
To mimic the nutrient composition of the 
20MDGS treatment, the 20FIB treatment 
contained 1.5% solvent extracted germ 
meal (SEM) and 7% wet corn bran from

Summary with Implications
A fi nishing study was conducted to 
determine the value of the fi ber in distillers 
grains plus solubles on cattle performance. 
Five treatments were evaluated: a corn 
control diet, 20 or 40% modifi ed distillers 
grains plus solubles, plus two diets containing 
corn germ meal and corn bran balanced to 
equal the fi ber content of the two modifi ed 
distillers grains plus solubles diets. Th ere was 
a signifi cant improvement in ADG and F:G 
for cattle fed modifi ed distillers grains plus 
solubles compared to control. Cattle fed the 
corn germ meal and bran diets had increased 
DMI, slightly lower ADG, and poorer F:G 
compared to the control. Th e isolated fi ber 
component had 83– 90% the feeding value 
of corn, while modifi ed distillers grains plus 
solubles had 107– 108%. Other components 
in distillers besides fi ber must improve the 
value of distillers compared to corn.
Introduction
Distillers grains are commonly fed in 
fi nishing diets. Th e ethanol industry has 
recently started removing components of 
distillers grains, such as fi ber components 
and corn oil, which changes the nutrient 
content of distillers grains plus solubles 
that are available to be fed. In recent years, 
research has been done using these compo-
nents to formulate diets that give the same 
performance as feeding distillers grains. 
Feeding the fi ber portion resulted in the 
closest performance to the DGS diet in one

Results
Initial BW (P = 0.63; Table 2) was not 
infl uenced by treatment, based on alloca-
tion. Intakes were impacted by treatment 
(P < 0.01) and DMI increased with MDGS 
inclusion, with steers fed 20MDGS having 
the greatest DMI. Steers fed 40MDGS or 
40FIB had similar DMI (P = 0.76), whereas 
steers fed 20MDGS consumed more (P < 
0.01) than steers fed 20FIB. When 40FIB 
was fed, DMI increased linearly (P = 0.01) 
relative to CON. Dietary treatment impact-
ed ADG (P < 0.01), as ADG increased with 
MDGS inclusion, and equal ADG between 
20MDGS and 40MDGS (P = 0.96). Feeding 
20FIB and 40FIB slightly reduced ADG 
but not statistically (P > 0.14) compared to 
CON. As a result of increased ADG, F:G 
improved linearly (P < 0.01) for steers fed 
MDGS. When steers were fed 20FIB or 
40FIB, F:G increased linearly (P < 0.01) 
due to an increase in DMI and numerical 
decrease in ADG compared to CON. Th e 
feeding value of MDGS relative to corn 
(diff erence between test G:F and control 
G:F divided by control G:F, then divided by 
by- product inclusion level) was 107% for 
20MDGS and 108% of corn for 40MDGS. 
Th e isolated fi ber treatments had feeding 
values that were lower than the control at 
83% for 20FIB and 90% for 40FIB. Th e cat-
tle performed as expected with the MDGS 
treatments showing the best performance 
and the fi ber treatments having reduced 
performance. Steers on the MDGS treat-
ments had the greatest HCW (P < 0.01) and 
fat thickness (P < 0.01) compared to the 
other three treatments. Cattle fed 20MDGS 
had the highest marbling (P < 0.01), with 
the other four treatments being lower and 
not signifi cantly diff erent from each other.

Conclusion
Th ese data illustrate that F:G was poorer 
if only the fi ber components that typically 
comprise distillers grains replace corn. 
Th ese data suggest that the isolated fi ber 
component does not give equal perfor-
mance to feeding MDGS. It is unclear what 
impact a removal of a portion of the fi ber 
from distillers may have, if other com-
ponents are concentrated. Th ese data are 
based on fi ber isolated from the wet milling 
process, but presumably applies for fi ber 
from distillers grains plus solubles as both 
are isolated from corn grain.

Erickson, professor Animal Science, LincolnConclusionTh ese data illustrate that F:G was poorer if only the fi ber components that typically comprise distillers grains replace corn. Th ese data suggest that the isolated fi ber component does not give equal perfor-mance to feeding MDGS. It is unclear what impact a removal of a portion of the fi ber from distillers may have, if other com-ponents are concentrated. Th ese data are based on fi ber isolated from the wet milling process, but presumably applies for fi ber from distillers grains plus solubles as both are isolated from corn grain.Table 2.
