Hostazym® X outperforms Axtra® XAP in broiler productivity

Hostazym® X contributes, on average, 3% extra performance and additional profit of €50 per 1000 broilers produced.

Commercially available NSPases vary significantly in their composition; this makes comparing products more difficult as the majority of the time different products (in their enzyme content or substrate target) are tested against each other. Nevertheless, in current market conditions these different products compete in the same segment. One example product is Axtra® XAP, an enzyme formulation containing xylanase, amylase and protease, which is positioned alongside other fibre-degrading enzymes.

To understand how Axtra® XAP performs in comparison to Hostazym® X (an enzymatic complex specifically developed for fibre degradation) and whether there is an additional performance benefit with the presence of amylase and protease, a broiler performance and carcass characteristic grow-out trial was conducted at Texas A&M University (USA) using pelleted corn - soybean meal based diets up to 49 days of age. 

Figure 1. Hostazym® X outperforms Axtra® XAP in broiler performance: final weight and FCR at 42 and 49 days of age.

The trial results (summarized in Figure 1) show that: 

• Only Hostazym® X had significant effects on performance parameters compared with the control group (+80g and +130g in body weight and a 6-point and 8-point improvement in FCR, on day 42 and 49 respectively, p < 0.05)
• The Hostazym® X group had better zootechnical results compared to the Axtra® XAP group (+70g and +90g in body weight and a 3-point and 5-point improvement in FCR on day 42 and 49 respectively, p < 0.05)
• Whole chicken with breast, legs and wings was higher in the Hostazym® X fed broilers compared with the control and Axtra® XAP groups (78.7% vs 78.2% and 78.1%, respectively)
• White meat yield (breast and tender meat) in the Hostazym® X fed broilers was higher compared to the control and Axtra® XAP groups (26.0% vs 24.9% and 25.0%, respectively)

Based on the additional performance benefits, economic calculations show that Hostazym® X can deliver an extra net saving of €0.06 - €0.10 per bird at day 49 when used instead of Axtra® XAP. 

Key facts

Hostazym® X outperforms Axtra® XAP, delivering: 

• extra technical performance: up to 90g higher final weight and up to 5-point improvement in FCR
• better carcass quality: up to 1% more meat yield
• better economic performance: up to €0.10 extra per broiler at day 49
