I. INTRODUCTION Growing emphasis on environmental regulation requires global animal production to adopt strategies like feeding low CP diets to minimize nitrogen excretion. However, in some of the animal feeding studies, lowering dietary CP beyond a certain level showed undesirable effects on growth performance and carcass quality of broilers. A number of explanatory approaches is being debated as ...

Dr. Andreas Lemme, Director of Technical Consultancy, answers the question: what hinders or limits protein reduction today? “Firstly, one needs to have good knowledge about the composition and quality of feed ingredients. Technologies are available to quickly get the required information. In the context of amino acid nutrition, we have developed near-infrared spectroscopy calibrations to get the f ...

Iván Camilo Ospina-Rojas, I believe that Dr Andreas' considerations are pertinent. As for the information used to obtain the digestible arginine (ARGD): digestible lysine (L D) ratio, I think it should be used only from studies where this determination was made using a diet with a sub-optimal level of LD. This is because in fact the birds demand is Aas gram per day not percentage. In this way, usi ...

Dear Camilo, it is always a challenge to compare literature data from different institutes produced under different conditions and to extract conclusions and/or recommendations. However, compiling the data is one issue and you determined (modeled) the SID Arg requirement accordingly. Indeed, changing production conditions might influence optimal concentrations.You also explained how you determined ...

Dear Juarez Donzele, I have to admit that I haven't followed the entire discussion herein but noticed the statements on D-isomers of amino acids. Indeed, the nutritional value of D-Lys (and others) is very limited in farm animals and therefore all supplemental amino acids - except methionine - are available as L-isomer only. Methionine indeed behaves different and as the D-isomer of methionine is ...

Key informationCompared to growing poultry, exact determination of the relative bioavailability of methionine hydroxy analogue compared to MetAMINO® is constrained by physiological mechanisms in laying hens which often result in overestimation of the relative bioavailability.The relative bioavailability of 65 % for methionine hydroxy analogue is applicable in layers and bears no risk in terms ...

Evonik is launching a new White Paper at IPPE in Atlanta addressing the ongoing debate on the relative nutritional value of methionine sources in poultry diets. The paper ‘Recent broiler trial confirms 2018 EFSA (European Food Safety Authority) scientific opinion on methionine sources while validating the experimental approach’ is by Andreas Lemme and Victor Naranjo, Evonik Nutritio ...

Evonik has rolled out a high-precision NIR analytical service, which enables the content of raw, unground feed materials to be assessed as soon as they arrive at the mill. The amino acid and macro-nutrient content of samples can now be analyzed quickly, straight from the delivery truck, cutting out the time-consuming grinding step. The results can then be compared to NIR calibrations of more th ...
