An inspiring article, Dr. Pesti; I often wonder how to integrate the new concepts regarding soluble and insoluble fiber—and the relationship between them—into the context of more precise energy valuation.Likewise, the correlations between metabolizable energy, net energy, and daily amino acid deposition during animal growth should help identify efficiency gains related to thermal comfort.

IntroductionPoultry scientists have long discussed and debated how the energy values of feed ingredients should be expressed (Zuidhof 2019). Pesti (2024) suggested that it is time for a paradigm shift in the way feed ingredient nutrient contents are described, and labeled the new categories collectively the Armidale method (see Fig. 1 for examples). He also proposed expanding the net energy (NE) t ...

Great discussion, Gentlemen, from many years (decades) following the field evolution, feed intake management was never assumed by the hunsbadry field team, and many aspects were sometimes delegated to the nutrition team. Besides that, investment in all aspects has made evolution possible. Recently, considering the numbers from Prof. Leeson´s paper, people are feeding the birds, projecting a 1,35 F ...

Thanks for the good information! The CP reduction without losing performance could be related to an indirect anti-nutritional and allergenic reduction. Concentrated protein sources like Glutenose or Soybean Protein Concentrate would be alternatives?

@Dr. Sudheer . It all depends on what is the definition of "good results". Several poultry companies in Colombia, South America, are truly experts in the feed restriction of broilers that are processed at 38-40 days, and their goal for "good results" is the lowest possible FCR independently of the cost per kg of live weight. However, for poultry companies whose goal for "good results" is the lowes ...

Thanks for the good discussion. I suggest also lowering the antinutritional and allergenics by changing part of the protein source Soybean meal for SPC Soybean Protein Concentrate. This will challenge the gut development less and also increase the whole feed digestibility.Currently, when the Microbiota is becoming in evidence, modulating its patterns to better diversity and consequently higher per ...

Dear Dra. Monika, congratulations for the great exposure. I understood that the lack of precision lowers the application in the field and so a standardized protocol would be helpful for this important technics adoption. But, in the other side, regarding of final standard reports considering the ative functional of Microbiota population, do you believe would be worthy?
