Abstract: The increased meat demand is a driver of poultry production which is expected to make up 39% protein source by 2030. This is because of its nutritional value, and also because there are no religious or cultural barriers hindering the production and consumption. The banning of animal products as a source of protein in the nutrition of animals in the EU, necessitates an alternative protein source. Soybean is considered as a source of plant protein in sustainable poultry production because it is relatively cheap and affordable. However, it contains anti-nutritive factors which inhibit the protein-enzymes activities. Therefore, enzyme use in poultry nutrition helps in inhibiting the activities of the anti-nutritional factors which interfere with feed digestion, nutrient distribution and invasion of pathogens. The aim of this 42-day research was to evaluate the impact of adding enzymes to soya pre-extrusion, through the assessment of effects of inclusion of treated soya on performance of male broiler chickens. Six dietary treatments with 8 replications were used (diet A with no enzyme, diet B, C, D, E, and F with enzyme supplementation) on 288 male Ross 308 broilers chickens. Weekly records of bird weigh, feed intake and body weight gain were taken to determine the impact of enzyme addition of soybean pre-extrusion on performance. No significant effect between diets with enzyme pre-treatment and diets with no enzyme pre-treatment on performance of male broilers. Birds fed diet B showed optimal performance improvement of FCR (1.44) and BWG (1000g) at week two and six respectively compared to other dietary treatments. However, the precision of the results obtained using the same enzyme-inclusion level is limited. In order to draw final conclusions, future research is needed to evaluate the impact of enzyme pre-treatment on extruded soybean in diets using different enzyme inclusion levels, large sample size. Lastly, for sustainable source of protein, more effort should be focus on developing alternative protein source rather than depending on imported protein source from other countries.
