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 ...

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 ...

SummaryThis study was conducted to test the efficacy of phytase in low phosphorus and calcium diets in the late production cycle for maintaining the productivity, eggshell and bone quality of hens fed low phosphorus and calcium.ProblemExogenous phytase supplementation has become a standard practice for poultry diets to liberate available phosphorus and reduce excretion of phosphorus in manure. Man ...

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 ...

DL-Methionine (DL-Met, 99%) and liquid DL-2-hydroxy-4-methylthio butanoic acid (methionine hydroxy analogue-free acid, MHA-FA, 88%) are often used in commercial poultry feeds to meet the requirements for Methionine+Cysteine (M+C). However, differences in chemical properties and absorption decrease the relative bioavailability value (RBV) of MHAFA, which corresponds to 65% of DL-Met for performance ...

Dear Luis,in the last few years, we had a close look at the quality of different protein-rich feed ingredients and we developed NIR calibrations which can now be used locally to estimate the quality. The reactive Lys to Lys ratio is a good indicator for over-processing and it works in Soybean products, but also in Canola Meal and DDGS. In Canola it might be worth to check in addition the levels of ...

OverviewRenewed interest, especially in the United States, has sparked in assessing branched-chain amino acid interactions in practical diets for broilers. Indeed, as L-valine enters formulation bird nitrogen excesses are reduced as diet protein falls to the new first limiting amino acid (e.g., isoleucine, arginine, or tryptophan). For a United States based example, the result is less oilseeds and ...
