Hi Prof Jarez, I think the authors can try to refit the graph (equation) by changing the x-axis to "Intake of supplemented Met" (rather than "% of supplemented Met). RBV can be based on actual intake of testing nutrients. I wish you are well! -Best, Sung Woo

Hello there. Based on my personal experience with phytase, beside considering phytase nPP equivalency (the value depend upon phytase origin and level), one should be very careful in considering phytase matrix value (for other nutrients such as amino acid, Ca, etc.) in practical diet formulation.

Mohammad Hosein Shahir I agree with this position especially in rations where phytase is not added

I think you should use calcium matrix value of phytase, otherwise, calcium to phosphorus imbalance (the ratio more than 2) occurs.

Dear Rami Unfortunately still many of the nutrients in feed specification for poultry is crude, like CP , CF , EE and of course Ca. Ca is usually over supplied to the poultry diet from many sources like: Drinking water (as a rule of thumb poultry take water twice the feed intake) , Carrier in premix , concentrate , pro-prebiotics also as anti-caking agent in SBM. For example when you add 1 kg ...

This review examines the relative bioefficacy of 2-hydroxy-4-(methylthio) butanoic acid (HMTBA) and DL-methionine (DL-Met) which includes chemical, metabolic, nutritional, and statistical aspects of its bioefficacy. The chemical, enzymatic and biological differences and similarities between these two products are explained and the evidence and reasons for HMTBA relative bioefficacy to DL-Met in mo ...

ConclusionThe present study conducted at Schothorst Feed Research resulted in an average bioavailability of MHA-FA and diluted DLM65 of 65% and 61%, respectively compared to MetAMINO® considering the overall growth and carcass parameters.These results demonstrate that the relative bioavailability of MHA-FA is significantly lower than its active content of 88% and consistent with the 2018 EFSA ...
