Utilisation of α-amylase and β-glucanase enzymes to improve the productivity of poultry farms

In modern poultry farming, increasing the efficiency of feed use is a key factor for increasing productivity and reducing production costs. One of the promising methods for improving productivity indicators is the use of enzyme supplements such as α-amylase and β-glucanase, which improve nutrient absorption by improving feed digestion. The purpose of this study was to evaluate the effect of α-amylase and β-glucanase enzymes in broiler diets on productivity. The study used broilers, which were divided into a control group and an experimental group. Weight gain, feed conversion rate, and nutrient digestibility were measured. Economic indicators were calculated based on feed costs and productivity of birds. The results showed that the addition of the α-amylase and β-glucanase enzymes significantly improved weight gain and FCR. Broilers receiving these enzymes showed improved body weight gain and lower FCR values compared to the control group. In addition, there was an increase in the height of the villi and the depth of the crypts in the tissue of the small intestine, which indicates better intestinal health and the ability to absorb nutrients. The digestibility of proteins and amino acids has also increased significantly. Improved nutrient uptake has led to a reduction in nutrient release into manure, minimising environmental impacts. Economic calculations have shown a reduction in feed costs due to the use of cheaper ingredients and an increase in overall productivity. There was also a decrease in the amount of abdominal fat in birds that were fed diets with enzymes. Prospects for further research are aimed at optimising enzyme dosage and investigating their effects on different poultry species and feed ingredients
