@Dr. Fiodor S. Marchenkov, totally agree, but there is also a big problem that impacts response of enzymes, most individual matrices are also evaluated under conditions that do not apply in practice, look values from phytase commercial phytases, blame 5 - 10 improvement on amino acids digestibilities at 500 ftu, but several New publications confirm papers published with Dr. Parsons lab, matrices d ...

@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.

@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.

I think the ME for enzymes depends birds age, enzymes composition, dietary /feedstuffs composition and energy value of the diet but it is safe to assume that it is equal to 50 kcal per kg diet but again depends on factors mentioned above.

1. IntroductionThe use of antibiotics growth promoters (AGPs) has been a common practice in intensive poultry production to improve animal growth performance, health, and sustainability of animal farming (1). However, AGPs threaten human health due to the risk of developing antimicrobial resistance and drug residue in poultry products (2). Consequently, AGPs have been prohibited in several countri ...

1. IntroductionThe use of a low-crude-protein diet fortified with essential amino acids is a part of a precision feeding and has gained commercial acceptance to improve protein utilization, minimize environmental impact and thus increase the sustainability of broiler production, because it reduces the cost of production [1–3]. Protein accounts for the second most expensive nutrient in poultr ...

IntroductionMicroorganisms constitute the largest fraction of biodiversity on Earth. Their functions are highly diverse, with fundamental roles to maintain chemical equilibria and cycles in their respective environments. It is, therefore, surprising that many humans consider all microorganisms as ”dangerous”, particularly when it comes to equating bacteria with pathogens (Musso et al., ...

Dr. Fiodor S. Marchenkov Many of those so-called nutritionally nonessential amino acids (NEAAs) are potent regulators of gene expression and metabolism in animals. Glutamine is a great example. Some NEAAs are the major metabolic fuels for enterocytes of the small intestine in a species-specific manner to support the intestinal integrity and function. There should be not such a thing as vegetable m ...

1. IntroductionThe permeability of the intestinal tract controls the uptake of nutrients and the transport of unwanted extracellular substances such as bacteria and xenobiotics, in addition to the non-digested substances. Therefore, gut health plays an essential role in the pathogenesis of various intestinal disorders. The permeability of the intestine is controlled by gut microbiota, digestive se ...
