Yes
@JacinLarkwell , don't feed Becky's Mix. and definitely don't feed Becky's no Soy mix.
Targets for a complete chicken feed, according to
NCRS, USDA, Universities like
UGA, etc
etc etc vary a bit with breed, differences in the research findings, etc, but in broad ranges, they recommend Protein between 16-20%, Fiber 3.5% +/-1%, Fat 3.5% +/-1% (+2% for CX being fattened for table weight, NOT for health), with an amino acide profile for the four most limiting of Methionine 0.6%-0.3% (higher for younger birds), Lysine 1.1%-0.7% (higher for younger birds), Threonine 0.8%-0.6%, Tryptophan .3-0.2%.
Garden Betty's mix calculates out (dry) as 15.8% Protein, 8.1% fiber, 14.1% fat!!! and AA content of 03, 0.6, 0.55, 0.21 (respectively). As fed (accounting for the moisture content), the numbers are even worse.
Her no corn, no soy, mix is 15.08% Protein, 8.72% fiber, 14.85% fat!!!, with AA of 0.3%, 0.57%, 0.53%, 0.21% (respectively). Again, "as fed" is worse.
While there is, of course, variation in sources (and varieties), BOSS is generally given number around 16% protein (not bad) and 48% fat!!!! So when using it in a feed, the first thing you have to do is thin it out with low fat sources to get closer to target. Its AA is pretty decent, .37, .66, .61, .22.
Corn is low protein, around 9.5% (best case, some of the new strains are as low as 7%), 2.5% fiber, 4.3% fat. Its AA is pretty terrible. 0.2, 0.29, 0.34, 0.07% because its protein is so low. So every scoup of corn makes it harder to hit AA targets, doesn't help with fat, and lowers overall protein.
Naked or Dehulled Oats helps make it a more concentrated nutrition source. Call it 13.1, 4.2 fiber, 5.1 fat, AA of 0.24, 0.55, 0.47, 0.16
DE and Grits have no nutritional value whatsoever, and DE's only value in feed is *possibly* assisting in killing grain mites and weevils burrowing through feed that's been kept in storage too long.
Therefore, and feed as described from those ingredients in combination will be protein deficient, massively high in fat, and have an inferior Amino Acid profile, further aggravating health concerns associated with protein deficient diets. The excess fat, of course, is associated with fatty liver disease and a host of other nutritional maladies.
My sources for nutritional values are Feedipedia.Org. There are, of course, other sources, but Feedipedia has the advantage of being one of the most complete - so I can't be accused of cherry picking data from different sources.
