You can. Its a common addition to many feeds, particularly those going for the Non-GMO and certified Organic labels. Or you could just build a few sprouting trays, and plant some marigolds in them. They are easy to grow, reseed well, and are reasonably hearty as long as the screen on the tray...

Yeah, I skipped right over that. Agree, obvious error. My run is "pretty big" - like 40' x 50' or 40 x 60' now that I've combined the two runs. Even the grow out pen (which I should be redoing after the goats broke the fence) is like 15 x 45, and its only intended for a dozen immature birds a...

Hmmm. I **KNOW** there's a significant difference between white corn and yellow nutritionally (beta carotene), and believe human selection had a hand in selecting for both from an earlier variety that was less digestible - but in which direction, from what color (blue???) and what the important...

I know that what they eat affects feed color - I can see it in my own flocks eggs as the seasons change and things go into or out of bloom, seed, etc. I don't how the process works, except at very high level, and am not convinced that the color of the thing necessarily relates to the color...

Not real concerned w/ the fat unless it goes much higher, there's a lot of dispute over appropriate fat content, I don't have a firm opinion, and haven't moved into that area of study deeply. Still working on understanding calciums and amino acids - mostly aminois right now. Observe their...

No, 100 gm /hen /day is a good place to start, then modify intake based on observed consumption.

My dealer doesn't know, I need to reach out to the mill directly. I do know (from the ingredients list) that they are supplimenting the amino acids that I would normally expect to get via soy and oats via the addition of pig meat and bone meal, fish meal (among other suppliments) - essentially...

then you eeduce everything else with it - including your amino acids, fat, carbs, vitamins, etc

i've only been doing this 15 months or so, started getting deeper into feed a few months ago. had skimmed some stuff over the first 12 or so, was a useful jumping off point.

i don't, sadly

Yup. There remains much disagreement in the industry. and there's variation in methodologies and assumptions. Even where methodologies (for testing amino acids content) are the same, the study assumptions can alter the outcomes. The conditions in which a battery hen is raised, for instance...

Which is why I look for soybean meal and/or fish meal in the ingredients list. Sunflower seeds are also a good source of Tryptophan (0.3), Methionine (0.435), Lysine (0.825) but sadly a HUGE source of fat (often over 50%). Its all a balancing act.

Triptophan isn't required to appear on labels, and thus doesn't. I use a local mill, and blend my own from their available feeds. The end result is NOT what I would recommend for the typical backyard owner, but I don't have the typical backyard flock or management practices. What I do...

Yes, as I said in one of my earlier post, I find the USDA nrcs numbers to be a little low based on some subsequent research..22 versus .16 doesn't really surprise me much.

Happy to help, and definitely interested in Kalmbach's response. Please share when they write back. I was expecting you could likely go to a 2 corn, 1 oat, 1 K 122p Suppliment mix and hit your targets, but it would be nice to have greater confidence in the tryptophan numbers. Curious as to...

I've not made specific study, however, a quick internet search turns up a few consistent reports in studies. Basal rations used to examine amino-acid requirements usually do little more than slow down growth or maturation rates. However, we have now found that for the chick, depending somewhat...

You are on the right track. Check out the tryptophan levels in Oats [hint hint]. This is a handy reference (its from a pro barley source, but it offers numbers in the same ranges as many others, and happens to place them side by side, which is convenient)

Took me a minute, too, though I'd seen some of his posts and responded in another thread. I was in desperate need of coffee. :caf Hope the morning finds you well.

^^^ Good advice, always. We have lots of posters on BYC complaining of apparent dietary imbalances in backyard flocks eating very expensive whole grain feeds. It doesn't matter what's in it, if your birds don't eat all of it - or the birds select out their favorites based on flock dominance...

@Auntiejessi3 he's propossing mixing that particular Kalmbach (essentially a high protein super vitamin mix) with the much cheaper corn to reduce its crude protein down to around 20% and otherwise control costs - it is, in fact, what that Kalmbach product is made for. Similar to feeding us...
