Dear Piotr, thank you very much for your point of view. It helps me use enzymes correctly, depending on the available substrates contained in the feed. I think that attention should also be paid to the methods of feed enzymes application, which have historically been used in different countries, this is 1) "over the top" of complete feed (for maximum absorption of nutrients) and also 2) "down spec ...

@Dr Valeriy Kryukov Thank you for your invaluable comment. Although the majority of biological reactions occurs in an optimum conditions such as optimal dose of phytase for soybean meal and other constitutes, its unclear why the higher dose of phytase for corn, for example, impaired the effectiveness of enzyme in soybean meal that required less phytase? Its an interesting point in the practical co ...

@Mangalmurti PathakIf analyzing substrates every time is impractical, so relying on average feed ingredient values from specific regions is a reasonable approach. The challenge of enzyme activity analysis is another hurdle since methods vary by supplier.But i think that the protein and amino acids provided by enzymes are not the same as calories.So they contribute primarily to growth, maintenance, ...

Amin Nthanga Thank you,in most pellet operations, 5% fat level is always problematic because you want to fine grind your materials before pelleting. Using a screen size of 2000 microns or less has proven this. When you are formulating a starter diet for a broiler, energy requirement is between 2950-3000kcal ME/kg. To reach this energy level at exact calorie protein ratio, an ingredient rich in fa ...
