I. INTRODUCTIONThe digestive dynamics of starch and protein are considered pivotal to broiler performance (Liu and Selle, 2015). Moreover, it was proposed that the rates of starch digestion and glucose absorption exceed the rates of protein digestion and amino acid absorption and this asynchrony in digestive dynamics compromises the performance of broiler chickens. If so, it follows that the provi ...

@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 ...

ABOUT MATRICES OF FEED ENZYME PREPARATIONS (translated from Russian). The feed contains known nutrients, the need for which has been established, so their concentration in feed is constantly monitored. However, they completely ignore the fact that they are present in the raw materials not in their pure form, but as part of complex structures. Scientific evidence points to the importance of the st ...

Abstract. The concept of a "feed enzyme matrix" has become widespread over the past 10 years. It is used to quantify the increase in nutrient utilization of a feed by the action of feed enzymes.The factors that change the matrix values of enzymes are given. Due to the impossibility of substantiating stable values of matrices, in official instructions the values of matrices are virtual, therefore, ...

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.

Barley ranks fourth in global cereal production after corn, wheat and rice. About 65% of the world’s barley produced is fed to animals, including poultry. Australia is a significant global producer of barley, ranking in the top 5 countries with about 5% of global production and is among the top 3 barley exporters accounting for about 30% of malt and 20% of feed barley trade. Australia is a r ...
