(P < 0.05). Total n-3 fatty acids constituted 1.19% in Control eggs 
compared with 3.12 and 3.09% in CAM-Seed and Flax-Seed eggs, 
respectively (P < 0.05). The total n-6:n-3 fatty acid ratio was 5.99, 
2.45 and 2.80 for Control, CAM-Seed and Flax-Seed, respectively (P 
< 0.05). Camelina meal or seed could be incorporated into layer rations 
as a source of energy, protein and n-3 fatty acids and Camelina meal 
would be more efficient in incorporating n-3 fatty acids into eggs than 
whole seed.

549   Metabolizable energy values of corn distillers grains and 
corn distillers grains with solubles for 6-week-old broiler chickens. 
O. Adeola and H. Zhai*,   Purdue University, W. Lafayette, IN.
The objective of this study was to determine the ileal digestible energy 
(IDE), ME, and MEn contents of corn distillers grains (DDG) and corn 
distillers grains with solubles (DDGS) for 6-week-old broiler chickens 
using multiple linear regression method. The birds were fed a standard 
broiler starter diet from d 1 to 21 post-hatch and a standard broiler 
grower diet from d 22 to d 35 post hatch. The analytical composition 
of DDG and DDGS used in this study were 4,879 and 4,762 kcal of 
gross energy/kg, 315 and 287 g of CP/kg, and 921 and 901 g DM/kg, 
respectively. The DDG and DDGS were incorporated into a reference 
diet at 3 levels (0, 300, or 600 g/kg) by replacing the energy-yielding 
ingredients. These 5 diets were fed to 240 male Ross 308 from d 35 to 
42 post hatch with 6 birds per cage and 8 replicate cages per diet in a 
randomized complete block design. The inclusion of DDG or DDGS 
to the reference diets linearly (P < 0.001) decreased ileal digestibility 
of DM and energy, total tract digestibility of DM, N, and energy, and 
IDE, ME and MEn in assay diets. By regressing the DDG and DDGS 
-associated IDE intakes in kilocalories against kilograms of intakes of 
DM in DDG and DDGS, the IDE regression equation was established 
as Y = −12 + 2,125 * DDG + 2,589 * DDGS, r2 = 0.96, which indicates 
IDE values of 2,125 kcal/kg for DDG and 2,589 kcal/kg for DDGS. 
Similary, the ME regression equation was Y = −17 + 1,988 * DDG + 
2,460 * DDGS, r2 = 0.97, which implies ME values of 1,988 kcal/kg 
for DDG and 2,460 kcal/kg for DDGS. For MEn, the regression equa-
tion was Y = −14 + 1,891 * DDG + 2,360 * DDGS, r2 = 0.97, which 
alludes to MEn values of 1,891 kcal/kg for DDG and 2,360 kcal/kg for 
DDGS. Based on these results, we calculated the advantages in IDE, 
ME, and MEn of DDGS over DDG used in this study to be 22%, 24%, 
and 25%.

550   Effects of the inclusion of oat hulls or sugar beet pulp in 
the diet on gizzard characteristics, apparent ileal digestibility of 
nutrients, and microbial count in the ceca in 36-day-old broilers 
reared on floor.  E. Jimenez–Moreno*, C. Romero, J. D. Berrocoso,

The effects of the inclusion of oat hulls (OH) and sugar beet pulp 
(SBP) in the diet on gizzard characteristics, apparent ileal nutrient 
digestibility (AID), and Clostridium perfringens, Enterobacteriaceae, 
and Lactobacillus proliferation in the ceca were studied in 36 d–old 
broilers. There were a control diet with a low CF content (1.61%) and 
2 additional diets that resulted from the dilution of this feed with 5% 
of either OH or SBP. Each treatment was replicated 7 times (10 chicks 
each) and birds were kept on pens with straw as bedding. Only one of 
the chicks of each of the replicates was used for microbiology counts. 
Broilers fed additional fiber had heavier gizzards (P ≤ 0.001) with 
higher digesta contents (P ≤ 0.001) and lower pH (P ≤ 0.01) than those 
fed the control diet. More digesta was retained in the gizzard with SBP 
than with OH inclusion, a finding that was presumably related with 
the higher water holding and swelling capacity of the SBP. Neutral 
detergent fiber, acid detergent fiber, and acid detergent lignin content 
of gizzard digesta were increased (P ≤ 0.001) with OH but not with 
SBP inclusion. The AID of starch was higher (P = 0.05) with OH than 
with SBP inclusion, with that of the control diet being intermediate. 
However, the AID of CP was not affected by diet. The inclusion of 
OH but not of SBP, reduced cecal counts of Cl. perfringens (P ≤ 0.05), 
Enterobacteriaceae (P ≤ 0.01), and Lactobacillus (P = 0.08). The data 
suggest that the inclusion of OH, a lignified insoluble fiber source, 
improves gizzard function and AID of starch and reduced cecal patho-
gen microbial count in 36 d–old broilers. Under practical conditions, 
feeding OH may be used to improve nutrient digestibility and control 
microbial growth in the gastrointestinal tract of broilers.

551   Effect of snack food byproduct on the feeding behavior 
and production parameters of laying hens.  R. C. Van Wyhe*, S.

The increased interest in becoming ‘green’ for consumers and com-
panies is driving groups to develop innovative ways to become more 
efficient and reduce their waste. Foods past their expiration dates are 
large sources of waste and are causing food-manufacturing companies 
to develop waste disposal strategies. Integrating by-products of these 
companies into animal diets, specifically that of laying hens, could be 
significantly more cost effective for both the human food manufactur-
ers and the agricultural producers. The study’s objective is to evaluate 
laying hen diets containing snack food by-product, consisting mostly 
of expired potato chips, and the impact on hen performance and feed-
ing behavior. One hundred and 92 white Leghorn laying hens (45 wks 
old) were selected from the MSU Poultry Farm. Hens were housed 
in conventional cages (3 birds/cage) and received one of 4 diets for 4 
wks: 1) industry standard corn-soybean meal control 2) control with 
3% by-product 3) control with 6% by-product and 4) control with 9% 
by-product. Diets were formulated to be isocaloric, isonitrogenous, 
and balanced for sodium. Feed intake was measured for 3 consecutive 
days each wk. During the first wk, feed intake was significantly higher 
in birds fed the 6% and 9% diets compared with those fed control 
(P < 0.05). Birds feed the 9% had a higher feed intake than control 
again during the fourth wk (P < 0.01). Egg production, egg weight, 
and specific gravity were measured weekly. Hen body wt was mea-
sured on day one and every 2 weeks thereafter. Egg production, egg 
wt, specific gravity, and body weight were not significantly affected by 
the addition of snack food by-products to the diet. In conclusion, the 
addition of expired snack food by-product into poultry diets does not 
significantly effect laying hen egg production and has the potential to 
be used as an alternative feed stuff in the future.
