I would not use it.@U_Stormcrow, what do you think of the H&H layer feed?
Targets for Lys and Met are 0.7 and 0.3, respectively (NRCS) and a trifle higher from other, more recent sources, for production layers. Once again, H&H has just 0.2% Met, which is the number one most critical limiting amino acid.
Essentially EVERY protein begins with Met at synthesis. Now many later strip the Met off. But in laymans terms, if you don't have Met, you can't synthesize proteins. That's why its so important, not enough Met, and the rest of the amino acids in the feed are simply wasted nitrogen, awaiting excretion.
