@Carlos Andrés Toro Good point—and 48V DC definitely helps with installation, safety, and maintenance.But the weak link is still the power conversion. LED drivers are non-linear loads, so they inject harmonics back into the system. That’s where total harmonic distortion (THD%) becomes the real metric to watch.The example I mentioned (three faulty drivers driving ~900 mV) was a rare failure case—bu ...

We have a existing 75 HP mill , the relief was moved to a bigger mill in a project before i started, we mill pea hulls so needless to say the large 150 HP mill struggles with the little suction fan and collector system. beyond my control they do not want to move mills around. What would just the asperation system cost to put under my 75HP mill?

@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 ...

For a discussion of the true protein content of feed ingredients and a pretty good N to true protein factor see Alhotan et al. (2024) https://doi.org/10.1080/23311932.2024.2428821. Of course it is better if true protein is determined from the sum of the amino acid residues.And then to balance true protein and dLYS see Alhotan and Pesti (2016) https://doi.org/10.1080/00071668.2016.1180666Some comme ...

Great opportunity to network with colleagues within the poultry industry and exchange knowledge and experiences, particularly in lighting, where HATO has been working to bring the best solutions, always prioritizing animal welfare.

Comment and questions: I've seen hand-held NIR devices lose their degree of accuracy over time (i.e. the nutrient predictions from the calibrations are horrible). The hardware is often jilted out of alignment because it gets bumped, dropped and mistreated at the farm/ feed mill level (i.e. it's used as a $20,000 hammer). Is this device susceptible to this issue? Also, does your NIR have the sp ...

There still seems to be considerable confusion about the concept of optimum dietary density and birds eating to meet their energy requirements or needs: “The broiler still eats quite precisely to its energy needs and alters its feed intake in response to variable diet energy level.” There is a classic graph in the 1974 paper by Colin Fisher and Brian Wilson, titled "Response to dietary energy conc ...
