Abstract

The aim of the current investigation is to demonstrate the effect
of supplementing corn – soybean based diets with enzymes and
probiotics preparation on quails performance. Four hundred and eighty
one–day–old Japanese quail were distributed randomly to four equal
experimental groups of 120 birds each. A conventional corn–soybean–
meal based diet was used. The basal diet was supplemented with three
experimental feed additives. The first feed additive was Xylam (-
xylanase, and amylase), it was added at the level of 0.5 g/kg diet.
The second feed additive was Samu Biogen (Bacillus subtitles Matta,
cellulase, protease, - amylase, and -amylase), it was added at the
level of 0.2 g/kg diet. The third feed additive was Organic Green
Culture (Saccharomyces cerevisae, Lactobacillus acidophilus, Bacillus
subtilis, Apergillus oryzae, protease, amylase, lipase, cellulase, and
phytase); it was added at the level of 1.5 g/ kg diet. The results showed
that Organic Green Culture supplementation increased final body
weight by 13.4 while in case of Samu Biogen or Xylam increased by
8.5 and 7.1 respectively, compared with the control. Feed consumption,
feed conversion ratio and mortality rate were also improved by the
treatments. Organic Green Culture supplemented group had
significantly higher weight of heart, thymus, spleen, and bursa
compared with the control. The red blood cells (RBC's) count was
significantly increased in response to Organic Green Culture followed
by Samu Biogen then Xylam. The same trend was evident for white
blood cells (WBC's) count. Plasma total protein, albumin and globulin
were significantly increased in birds received Organic Green Culture
and Samu Biogen compared to the control. Plasma aspartate
aminotransferase (AST) and alanin aminotransferase (ALT) were not
markedly affected by the feed additives used. Hemagglutination
Inhibition titer test (HI) was significantly higher in birds received
Organic Green Culture followed by birds receive Samu Biogen then
birds received Xylam. The lowest bacterial count was observed with
Organic Green Culture followed by Samu Biogen then Xylam
supplemented group compared with the control. The same pattern was
noticed with E. coli count. In conclusion, it is suggested that enzymes
with probiotics preparations are suitable for mixing with corn- soybean
based diets to improve quails performance and immunity
