Do you add stuff into your commercially available food?

[Perris]

That still doesn't tell me much, what was the nutrition profile of the feed?

It is all there in the thesis. If you want to know, read it.

Only applicable if suitable forage is available. If, as is true for many (certainly here in the US), that they have to keep their birds contained at all times, then it is certain that simply adding things to a commercially produced complete feed will likely affect its nutritional profile in detrimental ways. You need only read these.very forums to find ready example of it.

You may be comfortable with the idea that your birds can forage for what they need, and some very brief studies suggest it's not immediately harmful, but I submit that the lack of truly feral flocks self sustaining themselves in most of the world is ample evidence that what is true for you can not be safely assumed to be true for all others.

And if your birds can't forage, the study (with its many limitation) is simply irrelevant

@U_Stormcrow any thoughts on this?

For reasons not relevant here, I have no current access to my computer and my feed calculator. Cell phone isn't conducive to much in depth forum participation.

I have a recipe I screen capped from Barefoot Mimosas, I have a pic of the recipe. I love the idea of making food for the livestock. However, I'm also hesitant to just jump in after reading so much on here. With my last flock (2008-2013) I did whatever feed was on sale at our local feed store, I mixed some scratch stuff together, then they got kitchen leftovers, access to the compost pile.

I was thinking of doing the same approach this time, but wondering if I should just keep the feeder full of the commercially available stuff and then do a scoop of the mixed stuff for a better quality.

I've seen something like this "recipe" before. It wasn't as bad as I expected. Wasn't great. Certainly wasn't cost effective. Looks like a number of ingredients were slapped on to a superior recipe based on dubious claims and buzz words.

Also, People who know what they are doing don't mix weights and volumes. When my machine is accessible again, I can convert volumes to weight, then run the calculator. Which kelp?

I wish you would read things linked rather than assume their contents. The thesis was designed with the commercial poultry sector in mind. It uses typically commercial poultry breeds. Half the experimental birds were on typical commercial poultry concentrate. The hypothesis was that commercial operations can reduce their costs and improve their bird welfare by creating and using the outdoors for forage more than they do.

"It was concluded that high-producing layer strains are able to consume considerable amounts of herbage and that forage can provide laying hens with important nutrients. Chicory and quinoa seem promising, just as focus on earthworms has potential. Moreover, it seems possible to lower the standards of important nutrients in the supplementary feed, provided that good forage is available and that the production system supports good welfare of the poultry. A crop rotation system was suggested."
