Prebiotic Effects of Enzymes Benefit the Gut Health of Broilers

The role of Hostazym® X in promoting growth and improving nutrient utilisation is well recognised these days. However, there is more behind the mode of action of Hostazym® X apart from its effect on nutrient utilisation. 

Research has lately shown the effect of Hostazym® X on modulating gut microflora via a prebiotic route (Table 1). 

Table 1. Effect of Hostazym® X at 1500 EPU/kg feed on pH and lactobacilli count in the gastrointestinal tract, growth performance and feed conversion ratio of broilers

When Hostazym® X degrades arabinoxylan present in the diet, arabinoxylan oligosaccharides (AXOS) are released as a degradation product. These AXOS fulfil all criteria of a prebiotic: it is non-digestible, resistant to gastric acidity and fermented by colon microbiota stimulating specific gut bacteria in a positive way. When these gut bacteria ferment the AXOS formed by Hostazym® X, lactic acid is produced which acts as fuel for butyric acid-producing bacteria.

Butyric acid, a short-chain fatty acid, is an energy source for the gut cells so the gut integrity, the absorbing capacity of the gut wall and the gut barrier function, are improved. 

Thus, it is not surprising that besides improving growth and feed conversion, Hostazym® X shows in practical situations a significant reduction in mortality of birds. Therefore, the three effects of Hostazym® X are: 

  • the improvement in growth
  • the reduction in feed conversion
  • the reduction in mortality

Combined, these three factors can improve profits by more than €70 per 1000 broilers.
