Butyric acid is a good antimicrobial, only in those areas of the GI tract having a sufficiently low pH that creates the free non-dissociated form. Only this form can now pass through the cell wall to subsequently dissociate to lower microbe internal pH that creates lethality with all cells unable to accommodate. Such microbe lethality largely depends on concentration and occurs during passage of l ...

@Nisar Muhammad Khan Indeed, you are right, the more dietary protein is reduced the more non-essential amino acids become essential. While in the commercial examples shown in the article the NEAA levels are not a problematic issue per se, we clearly recommend to consider Gly-equivalents as those can become limiting. Recommendations can be found in AMINOChick.Indeed, research has shown, that Gly bu ...

@Nuhad Daghir Under experimental conditions you can even reduce more. However, the potential of CP reduction depends on the status quo. A good indication for protein reduction would be the nitrogen utilization which can easily be calculated by assuming 30 g N/kg BW. Indeed, nitrogen utilization is also a matter of age or final body weight but the article gives you an indication on German condition ...

Dear All,formulating in Bestmix, I also considered the total Ca and dig./av. P for the added phytase; and energy (ME) and AA for the NSP enzymes only. On this way I estimated to be on the safe side, because the nutrient matrix values indicate the amount of nutrient that could be released when the enzyme is added.In the past 10 years it became a trend to request and offer “matrix values&rdquo ...

Aaron Cowieson Well said Aaron. We should not be far from formulating diets based on digestible Ca and P,.....and probably digestible energy later on.

Great topic and well said! Since each farm has a unique water supply and system, producers need access to more than just a “chart” of facts but rather a systematic decision process that will lead them through understanding their specific issues and needs and provide them with the information and tools to make sound decisions based on the most current scientific knowledge available. Poultry Innova ...

Dear Alireza, thank you for confirming the concept by an additional data set. I like to pronounce, that validating the equivalency of DL-Met and the methionine hydroxy analogue at 65:100 replacement ratio not only results in same animal performance but also in considerable cost savings when using DL-Met provided the price ratio between mentioned products is not 65%, which means the price of the hy ...
