@Mohamed Fakhoury It is not difficult to analyse the substrate.Every time we can not analyse it as it is time consuming and expensive.We have to consider the average values of feed ingredients in perticular geographical areas.Plus we have to analyse the activity of enzymes based on the method of analysis as recommended by enzyme suppliers.Which is not again easy task.

Substrate Analysis: Verifying Substrate Levels in Diets Before Applying EnzymesEnzyme supplementation in animal feed is a highly effective tool for improving nutrient utilization, especially when it comes to breaking down complex compounds in raw materials like grains, oilseeds, and fibrous plant materials. However, for enzymes to be truly effective, their application must be based on a solid unde ...

Dear Mohamed, thanks a lot, 100% agree, actually and important.

Quite correct in your opinions. Also, adding more than one enzyme at a type can muddy the water on value. People can freeze on the bulk ingredients not knowing which substrate is benefiting from the enzymes and miss beneficial changes on the feed costs.

Thank you doctor, really i missed it, i appreciate it, I'm so sorry!

I think that we should look after: 1. Substrate Analysis: Verify substrate levels (e.g., phytate, NSPs) in diets before applying enzymes. 2. Context-Specific Ranges: Define ME ranges based on enzyme type, substrate, and bird age (e.g., 80–100 kcal/kg for xylanase in wheat-based broiler diets). 3. Dynamic Formulation: Use matrix values as a starting point, but adjust formulations based on: - Fe ...

@Akbar YaghobfarThanks for valuable information and contributions, the gut environment is also important and gut maturation is also essential as well as the strain of chickens broilers vs. layers, ducks and quail.There are many contributing factors to the nutrient matrix value of enzymes.

@Youssef Attia HelloIt is respectfully recalled that according to the results of the experiment using multi-enzyme with barley in the diet of laying hens, the quality of eggs, especially the shell, decreased. Please, if your scientific colleagues have observed such results and scientific articles in their farm or research experiments, please send them to the email below. ThanksYaqabfar@yahoo.mosha ...

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. ...
