YO GEORGIANS! :)

One of the things that feed manufactures are allowed to do (and Robert Earl does it too) is state that grains such as corn and wheat have protein, and state that legumes such as soybeans have protein. Such descriptors are really not true. Grains and legumes have incomplete proteins. In other words the amino-acid profiles of grains lack essential amino acids that would constitute a true protein, and the amino-acid profile of soybeans (including soybean meal) also lacks essential amino acids in order to be classified as a true protein.

Although there are some overlapping amino acids in the amino-acid profiles of grains and legumes, each group contains essential amino acids that are mutually exclusive to the other group. However, the good news is that a combination of grains and legumes (e.g., corn and soybeans) make up complete proteins. With that thought in mind, it stands to reason that a quality feed should contain a balance of both grains and legumes. The value of grains such corn, wheat, and rice are not so much in their intrinsic value in protein, but rather how they compliment the amino-acid profiles of legumes in feed to make true complete proteins that are usable by chickens.

Chickens (and humans) can manufacture non-essential proteins in the gut to make up some of the missing amino acids in corn or soy, respectively; however, complimenting essential amino acids must come from an outside source in order to produce true protein. In other words, for feed to contain true protein, it must contain BOTH legumes and grain, OR it must contain an animal-based protein such as fish meal.

It's just a peeve I have that feed manufacturers in particular are allowed use the word protein when independently describing grain and legume profiles, when amino acids would be the more accurate and honest descriptor.

great info! Thanks!!!
 
Sneak peek at what the inside walls are going to look like in the new coop.
First one is the wall
Second one is kitchenette counter
Third is the laying boxes. Of course being used for storage right now.

I checked Google Scholar and couldn't find any articles backed by scientific research that supported the no-supplemented-corn-for-chickens-when-its-hot idea. It's really just a personal choice as to what you do. I feed my chickens corn when it's hot and when it's cold and have never noticed a difference in their health. I also continue to give them air-popped popcorn and sliced corn of the cob as frequent snacks.

In addition, most pre-mixed chicken feed is 30% - over 50% corn. Anyway, let your conscience be your guide. lol

Speaking of mixing your own feed, check out the video below. Those who are interested in living through an apocalypse may find it interesting. (Check out the beer-bottle wall.):

i liked that video, when i get a chance im going to look at the other one
