(Rahmani and Speer,2005) who found higher
percentage of gamma globulin in broilers given
organic acids than the control ones. The enhancement
of immune response associated with dietary
acidification could be due to their inhibitory effects
against the pathogenic microorganisms throughout
the GI-tract.
The findings of serum lipid profile are in
agreement with Abdo and Zeinb, (2004), who
reported that blood total lipids and cholesterol
decreased significantly by dietary acidifiers. The
beneficial role of organic acids in reducing the blood
lipid profile may be interpreted through their
influence in decreasing the microbial intracellular pH.
Thus, inhibits the action of important microbial
enzymes and forces the bacterial cell to use energy to
release the acid protons, leading to an intracellular
accumulation of acid anions (Young and Foegeding,
1993). Also, Abdel-Fattah et al. (2008), show that,
the observed lower feed consumption (Table. 2),
during the period of growth and consequently lower
fat intake that resulted in fat depletion may also
contribute in reducing blood lipid content. Moreover,
the observed hyperthyroidism (Table 6) associated
with dietary organic acidification could also explain
the observed reduction in serum lipid profile.
The increase of Ca and P levels in blood serum
produced by addition of organic acids may be
attributed to the lowering of GI-tact pH by using
these acids, which increases the absorption of such
minerals from the gut into the blood stream.
Improving the utilization of calcium and phosphorus
by organic acids supplementation was revealed by
Boling et al.(2001). Also, Abdo and Zeinb (2004).
observed an increase in blood calcium of broiler
chicks fed on dietary acidifier. In this respect, Abdel -
Azeem et al. (2000) and Edwards and Baker (1999),
found that, the acidic anion has been shown to
complex with Ca, P, Mg and Zn, which results in an
improved digestibility of these minerals.
Furthermore, (Kishi et al.,1999) reported that dietary
acetic acid prevented osteoporosis, through reducing
the bone turnover, as it enhanced intestinal Ca
absorption by improving Ca solubility in
ovariectomized rats.
The result of ALT and AST means that broilers
could tolerate the addition of 3% organic acids
without any deleterious effects on liver functions.
These results are in full agreement with those of El-
Kerdawy (1996). While, Abdel-Azeem et al. (2000)
showed that level of AST wa
The findings of uric acid are coincide with
Sturkie (1986)who revealed that dietary addition of
organic acid slightly reduced serum concentration of
uric acid. This result could be referred to the better
utilization of protein and amino acid digestibility. As

metabolism
In conclusion, this study outstanding the
importance of using organic acid as feed additives to
improve the growth performance of broilers through
their physiological action in inducing the growth and
activities of some endogenous mechanisms and their
beneficial antimicrobial effect which may be
responsible for better performance. Further studies
are needed to throw more light on the developmental
effects of those organic acids on the broilers
physiological functions, with the consideration of
using different levels and combinations
