Digestible lysine requirements of male broilers from 1 to 42 days of age reassessed

Juarez Donzele you raised a valid question, ideal amino acid profile play a vital role in growth. I have a little bit of confusion and think you will make it clear: say I'm following ideal profile but only lysine goes high, what will be fate of additional lysine? Either it will disturb the profile or only required level will play a role and additional allowance will withdraw.

While formulating a diet for broiler I have the practice to use additional Lysine as if Lysine is deficient in diet all other amino acids will be in extra mode and these amino acids crossing the ideal profile cannot play a role, but if lysine levels are only high, only lysine will be some extra, other amino acids will play their role. 2nd thing: lysine is most heat labile amino acid, if we supply some additional lysine what will be its effects?

Thank you for the answer, Dr.

I'm very interested in everything that has to do with mineral and vitamin supplements and, since you are specialized in nutrition, I appreciate your help in keeping me informed of all that is new.
