hens (P < 0.05). However, on d 8, H-AF hens liver wt was greater than 
the liver wt of H-CF hens (P < 0.05). The ratio of ileum weight and 
length was reduced in both H-CF and H-AF hens compared with their 
controls (P < 0.05) on d 1; while H-CF hens tended to be different on 
d 8 (P = 0.08). H-CF hens ate less than C-CF hens during d 1, 3, 6, and 
8 (P < 0.01) while H-AF hens ate less than controls during d 3 and 6 
only (P < 0.01). Partial pressure CO2 (pCO2), HCO3¯, and total CO2 
of cardiac blood of H-CF hens was lower than C-CF hens (P < 0.05) on 
d 8. However, only p CO2 was decreased in H-AF hens compared with 
controls (P < 0.05). Low pCO2, HCO3¯, and total CO2 are indicative 
of respiratory alkalosis or metabolic acidosis that can onset under HS 
through excess hyperventilation. These data suggest that hens exhibit 
a negative response under HS. Evidence is provided that hens fed AF 
have an improved coping capability to HS.

Grit (versus 0%) were evaluated in broiler feeds in two series with 
increasing levels of metabolizable energy under disease stresses in 
floor pens. J. L. McNaughton1, D. Fodge2, W. W. Emerson3, and D.

Azomite Feed-Grit (AZO; Azomite Mineral Products, Inc., Kansas 
City, MO) was included at 0 or 0.5% in broiler diets in 2 series with 
increasing metabolizable energy (ME) to study live performance and 
energy uplift effects. The AZO is a hydrated Na-Ca aluminosilicate, 
from a volcanic ash and an ancient seabed deposit in Utah, which 
has been shown to improve caloric conversion. Mash feeds were in 
3 phases (starter 0–21 d, grower 21–35 d, and finisher 35–42 d) with 
respective ME levels of 3,086, 3,142, and 3,197 kcal ME/kg and +0, 
+22, +66, or +132 kcal ME/kg. In the 0.5% AZO series of diets, soy-
bean oil was added to make formulas equicaloric with corresponding 
0% control diets. A total of 4,320 straight-run broiler chicks were ran-
domly allocated at 54 chicks/floor pen into 10 replicate pens for each 
of the 8 treatments (4 with 0% and 4 with 0.5% AZO). Stocking density 
was 0.0743 m2 (0.8 ft2)/bird on used litter. A live coccidia vaccine was 
given at hatch, and BMD (55 ppm) was used in all diets. Eimeria acer-
vulina (100,000 oocysts/bird) and maxima (50,000 oocysts/bird) were 
given on d 5, Clostridium perfringens (104/bird) on d 8, and E. coli 
(106/bird), Salmonella spp. (104/bird), Listeria monocytogenes (106/
bird), and Campylobacter jejuni (104/bird) by oral gavage on d 40. The 
42-d BW was 2.545 kg for the 4 0% and 2.578 kg for the 4 0.5% AZO 
groups (P = 0.056). The 0–42 d feed conversion ratio (FCR) was 1.834 
for 0% and 1.817 for 0.5% AZO groups (P = 0.007), and mortality-
adjusted FCR was 1.831 for 0% and 1.813 for 0.5% AZO groups (P 
= 0.002). Mortalities were similar (1.71 vs 2.04%, respectively; P = 
0.494). The AZO at 0.5% was estimated to have 7,910 kcal ME/kg 
(3,588 kcal/lb) 0–21 d, 10,194 kcal ME/kg (4,624 kcal/lb) 21–42 d, 
and 9,744 kcal ME/kg (4,420 kcal/lb) of product 0–42 d. The AZO (a 
noncaloric ingredient) at 0.5% of diets increased effective ME level by 
48.72 kcal ME/kg (22.10 kcal/lb) feed from 0 to 42 d.

116   Growth response of broiler chickens to inclusion of hydro-
lyzed porcine mucosa (Palbio) in diets varying in total lysine con-
tent. M. Mohiti-Asli1, M. Frikha1, C. Jabbour1, E. Borda2, L. Cámara1,

The growth response of broiler chickens to the inclusion of hydrolyzed 
porcine intestinal mucosa (PAL, Palbio 50 RD; Biobérica, Spain) in 
diets varying in total lysine (Lys) content was studied in 2 experiments 
(Exp.). In Exp. 1, 1,200 one day-old, straight-run Ross 308 chicks 
were allotted randomly to 8 dietary treatments with 5 pen floor repli-
cates of 30 chicks each. The design was completely randomized with 
treatments arranged as a 4 × 2 factorial with 4 inclusion levels of PAL 
(0, 2.5, 5.0, and 7.5%) and 2 levels of Lys (1.23 and 1.37%). Birds 
received their respective experimental diets from 1 to 21 d and then 
a common diet without PAL from 21 to 37 d of age. Lys level did not 
affect ADG in any of the periods considered but final BW tended to 
be higher (2,662 vs. 2,707 g; P = 0.063) for birds fed the higher Lys 
level. The inclusion of PAL tended to improve ADFI (P = 0.08) and 
improved BWG (P ≤ 0.05) and FCR (P ≤ 0.001) from 1 to 21 d of age. 
Previous treatment did not affect broiler performance from 21 to 37 d 
of age. Litter quality was not affected by diet. In Exp. 2, the same diets 
used from 1 to 21 d in the previous study were used from 1 to 37 d of 
age. For the entire experiment, birds were kept in cages and each of 
the 8 treatments was replicated 5 times (7 birds each). Birds fed 1.37% 
Lys had higher ADFI and ADG (P ≤ 0.01) than birds fed 1.23% Lys. 
The inclusion of PAL improved ADFI and ADG from 1 to 21 d (P ≤ 
0.01) and from 1 to 37 d (P ≤ 0.05) of age, with best results observed 
with 2.5 to 5.0% PAL. Moisture content of the excreta was not affected 
by dietary treatment. The results indicate that PAL inclusion improves 
growth performance of broilers and that the most efficient level of 
inclusion is between 2.5 and 5.0%, irrespective of dietary Lys level. 
Moreover, broilers respond better to diets with 1.37% Lys than to diets 
with 1.23% Lys.

117   Impact of replacing canola meal with distillery yeast sludge 
on growth performance, haematology, histopathology and growth 
performance of broilers. J. I. Sultan*, I. Haider, A. Javaid, and M.

The intent of this study was to determine the chemical profile and 
to explore the impact of replacing canola meal with distillery yeast 
sludge (DYS) on hematology, histopathology, growth performance 
and economics of broiler chicks. Two hundred 40 (240) day-old broiler 
chicks were randomly divided into 20 experimental units in such a 
way that each diet was offered to 4 experimental units comprising 12 
chicks. Five isonitrogenous (CP, 21%) and isocaloric (ME, 3000 Kcal/
kg) broiler diets i.e., control, DYS5, DYS10, DYS15 and DYS20 were 
formulated having 0, 5, 10, 15 and 20% DYS replacing canola meal. 
The trial was 42 d long. Feed intake remained unaltered across all 
diets. Weight gain of chicks fed control diet was higher (P < 0.05) than 
those fed DYS20, however, it was similar to those fed other diets. Feed 
conversion ratio was lower (P < 0.05) in chicks fed control diet than 
those fed DYS20, however, it was similar across other diets. Red blood 
cells, white blood cells, packed cell volume and hemoglobin values 
remained unchanged with increasing the inclusion level of DYS in the 
diet. No pathological lesions on heart, kidney and liver were observed 
across any diet. Feed cost per kg live weight gain decreased (P < 0.05) 
as the level of DYS was increased in the diet. Based on the findings 
of the present study it was concluded that DYS is economical protein
