In the last decades, a lot of studies have been conducted in relation to the use of exogenous enzymes in bird feeding. The effect of using NSP-enzymes and phytase has been proven convincingly. 

Nowadays, scientific research focuses on protease, and the arguments for this shift are very solid. The material costs of the feed for broilers have increased, as well as the price of soybean meal, which is a major source of protein in the blends for poultry. This requires exploring new opportunities to reduce the content of soybean meal in the feeding of birds by compensating with better digestibility. 

In the past it was thought that birds produce enough protease for efficient protein digestion and absorption. However, recent data on the mechanism of protease action indicates an increased need for this enzyme. The obtained results are influenced by various factors such as the type of protease (acid, alkaline, neutral), its activity and dose, composition of the compound feed to which it was added (e.g., whether other exogenous enzymes are involved), the age of the birds, etc.

The protease enzyme supplement VemoZyme P from VEMO Corp., Bulgaria, is a stable, broad-spectrum protease, optimized to work efficiently in the animal’s digestive system.

The addition of 250 g/t of feed from the protease product VemoZyme P to compound feeds with a reduced level of crude protein and amino acids reliably increases live weight, equal to the control group, achieves feed conversion comparable to birds fed a standard feed mixture, and is cost-effective.
