Feed Ration in Pastured Poultry Profits by Joel Salatin

My copy of the book shows the recommended feed ration last updated in 1996.
I'm sure this recommended ration has been updated since 1996, does anyone know what Salatin's current recommendation is?

For those curious, the recommended ration in my book (measured in lbs.) from 1996 is:
corn: 5,000
wheat middlings: 2,000
soybean meal: 1,000
roasted soybeans: 1,000
meat and bone meal: 600
fish meal: 300
alfalfa meal: 400
kelp meal: 165
brewers yeast: 150
probiotic: 20

I'd be willing to bet he doesn't recommend soy nowadays.

I'm going to be raising more "wild" chickens, and will not be raising cornish cross, because I'm in a tropical place with lots of disease pressure, steep slopes, rough terrain, and need the birds to pick bugs off trees in the food forest. So my mobile tractor, will be a mobile coop completely closed to predators with a hardware cloth floor, and the birds will be moved to a new location everyday in the food forest, and allowed to free range. Still, I want to give the birds a great feed so they can convert it to fertilizer for my trees. I'd like to substitute the soy with pigeon peas, because they are available locally. I'm not sure I want to use wheat. What are middlings?

I like the other ingredients: Meat & bone meal (as long as I can assure it contains no chicken), fish meal, alfalfa meal, kelp, brewers yeast, probiotic.


I assume those supplement ingredients are the key takeaway from the book, and one can otherwise be pretty flexible with the other bulk grain and seed inputs.

Corn is available from local small farmers, so that ingredient is pretty easy to source here. Corn seems like such a staple, I'm not sure you could substitute it with anything.

Joel I believe still uses soy.  It’s really hard to get enough protein for fast growing broilers without it.  His argument is that high levels of grass consumption counters whatever downsides there to soy in the feed.

Why are you worried about chicken bones in the bone meal you add?  Chickens are shameless cannibals.  Heck, I’ve fed cooked chicken meat to them when it was that or let it go bad (not set up to compost meat).

Yeah, I've predators get into a chicken tractor and wound birds. The other chickens just ignored the predator and went after their wounded friends, dis-embowling them and eating them alive while they tried in vein to escape.

It was a wake up call to just how brutal mother nature is.

I'm pretty sure the book mentioned how cannibalism can lead to disease.
