@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, ...

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 ...

Thanks for the great topic and content. Some doubts arise during the paper reading, it would be better to increase CP digestibility by reducing the antinutritional and allergenics, using ingredients like SPC (Soybean Protein Concentrate), or decrease CP by using "pure AA" to meet the regular requirements.A second question, regarding soluble fiber, would be better to reduce soluble fiber or take th ...

Hi dr. Piotr Stanislaski When incorporating enzymes into poultry nutrition, several common mistakes can undermine their effectiveness and economic benefits. Here's a structured overview of these pitfalls: 1. Incorrect Enzyme Selection.- Substrate Mismatch: Using enzymes not tailored to the feed's composition (e.g., neglecting xylanase for wheat-based diets rich in NSPs).- Phytase  misapplication. ...

@Pirzado M Zakria when you are using phytase you should spare calcium and phosphorus, when you are using protease you can spare amino acids and when NSPase you can spare energy from your diet according to supplier's recommendations, it is simple rule.
