Practical aspects of enzyme-probiotics preparation supplemented to quail diets

الملخص EN

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.
