Youssef Attia I agree with you because birds will drink more under heat stress as seen in tropical regions. So any substance to reduce stress should be better administered through water, but I wonder if this is always the case.

Water supplements are more effective than in feed supplies due to many well known factors affecting feed intake praticulary during heat stress. The response to organic ligands depends on mineral status of the feeds as said.

Each phytase has an optimum pH with ftu’s conveying its relative activity under that specific condition. Phytases first act during storage in the crop with pH’s varying between 4-6 over varying durations. This ingests is conveyed into gizzard where pH’s decrease to 2-3 again over varying durations. Phytases of different pH optima continue to function through crop and gizzard only ...

Hello all,From the point of view of enzyme activities, the standard measure is how many moles of the product (the result of the chemical reaction) is released by a specific amount of the enzyme during a specific time and pH conditions. Although I am a biotechnologist I have worked in the animal industry and know that information does not translate well with industrial enzyme users. However, in the ...

Park W. Waldroup It is not completely useless if you know the relative value of each phytase product. I suppose the efficacy of each phytase mainly depends on pH optimums and how fast the phytase works and that is why one FTU is not always one FTU in vivo. In Danish pig production, we do not use phytase matrix values when we formulate feed. Instead, each raw material has individual values for the ...

Gene Pesti, I agree with you absolutely to involve professionals. In my opinion, this is a point in favour of multidisciplinary research because it gives room for a more rounded approach that will be most applicable and effective. Studies on feed enzymes will turn out results that better address these perennial issues when a multidisciplinary approach is employed.

For sure enzyme responses are non-linear but in the range, we test them in animal nutrition they occasionally appear linear. I think it is crucial to also examine available/reactive substrate concentration when interpreting enzyme response. Systems may be saturated with the substrate in which case enzyme responses may be exaggerated across a wide range of inclusion concentrations, or they may be s ...

Conclusion The 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 ...

The biggest challenges facing the poultry industry today include disease prevention, particularly in the absence of antibiotics, and optimum nutrition, especially with regards to being able to incorporate novel/local ingredients into the diet. Interestingly these two are linked as much of the disease pressure that challenges current poultry production is enteric in its nature. Since the presence o ...

Hi again Mike, and thanks for your comments. So let me see if I got it well: NSPases included will "encourage", by means of releasing shorter molecules- AXOS?- from that specific undigested fibre in diet, to try and digest more efficiently the rest of it? Apologies by coming back to you again......And many thanks again.
