Hi and welcome to BYC
I can tell you've put a lot of effort into this... I would suggest two books if you want to learn more about feed.
If you were to pursue your own recipe You'll need a vitamin pack. I recommend Fertrell Nutri-Balancer I would also recommend them for kelp and fish meal largely because I know the level of effort they put into finding their ingredients and ensuring that what's provided is organic and good for our birds. Also, if you're a fertrell customer you have access to their nutritionists.
I've taken a stab at your recipe to show you where you're at. There are a number of upper limits in feed recipes, for example barley and oats combined should not exceed 15% by volume. I don't have the analysis for the brewers yeast, so it is not included in the analysis below. But here's what your recipe looks like.
Nutrient Name: Amount Units
Crude Protein 13.6% %
Crude Fat 7.7% %
Crude Fiber 6.5% %
Calcium 0.17% %
Phosphorus 0.46% %
Salt added 0.09% %
Sodium 0.07% % per KG
Energy 1,315 Kcal/LB 2893.2
Vitamin A 58 IU/LB 128.44
Vitamin D 0 IU/LB 0
Vitamin E 0 IU/LB 0
Choline 1659 IU/LB 3649.3
Biotin 27.6 MCG/LB 60.722
Manganese 99.2 ppm 218.3
Zinc 28.3 ppm 62.212
Copper 9.88 ppm 21.741
Selenium (added) 0.00 ppm 0.0041
Lysine 0.59% %
Methionine 0.26% %
Methionine/Cystine 0.43% %
Arginine 0.78% %
And here's what a Sustainable Poultry Network (SPN) Grower ration would look like for comparison.
