@Gene Pesti , I agree - we need to distinguish between "significance" and "relevance" on one hand and controlled scientific conditions with many replicates resulting in strong statistical power and commercial conditions which are characterised by many influence factors and especially between farm (even house) variance.Regarding relevant differences, I know integrators who observe their meat yields ...

Dear Matheus, dear authors, Indeed, a nice study, and thank you very much, as research on SAA and Thr responses for modelling and optimization purposes became scarce in recent years. While I agree and applaud the dose-response data and the way you utilised them, I would like to add that both SAA and Thr have a very high involvement in maintenance metabolism and as functional amino acids. Therefore ...

@Dr Kotaiah Talapaneni Thank you for this comment! This is indeed a clear dilemma and we may distinguish the aim for the two different nutritional strategies. Indeed, genetic potential of broilers is continuously improving and if diets are formulated accordingly, unbelievable performances can be achieved. A feed conversion ratio of 1.35 at 40 days is commercially achieved in some regions of the wo ...

@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 ...

@Dr.Dharavath Rammbabu Agree, Our clear recommendation is to formulate diets on digestible amino acids of ingredients in order to consider this.
