I asked him about the cost of supplementing their feed with hemp seed.
His response:
Hemp seeds sell wholesale at 0.55-0.65 cents per pound; roughly equivalent to premium organic certified poultry food. Not cheap, yet, but also not break the bank extraordinarily costly if you buy in any decent qty.
Do not feed poultry more than 30% of their overall intake in feed with hemp seed, and there were no noticeable benefits to incorporating *more* than 20% in any study so far done. Hemp seed is a little short on lysine, one of the essential amino acids. Whichever amino acid is the least, is the limiting amino acid; and in this case, that's lysine. This being said, it's not like it's anemic in lysine; just the least plentiful out of them all. Corn is very rich in lysine, so you still want quite a lot of their feed component to be corn.
Also there is an adjustment period while the birds become accustomed to the new food. It would be best if hemp seed is first introduced as a voluntary 'treat' for a week, then incorporated in to their main food at 10% for a week, then 20% for a week, and then remain there.
The nice thing is hemp is rich in methionine, and all feed (organic or otherwise) has
synthetic methionine (chemically produced) in it as a supplement. So you can fully forego using synthetic methionine in your feed composition
Sidenote: The main goal I am trying to accomplish, methionine is the last remaining allowed synthetic additive to certified organic poultry feed; as soon as an alternative, such as hemp, is available, then NO certified organic poultry farmers will be able to use synthetic methionine, and ALL certified organic poultry companies MUST use the available organic ingredient! Read this, as "Trent Profits Greatly" because for a period of time all certified organic poultry farms - and there are many, with millions of birds, will be required by law to incorporate the sole organic ingredient - hemp seed/protein - in to their poultry diet. From year 1 after hemp seed / protein is allowed for poultry *all* poultry operations will be dependent on hemp seed for a natural source of methionine and an *immediate* market opens up that is worth roughly 500 million per year, in the USA, for hemp seed sales to certified organic poultry operations. If I have the best genetics for growing this grain per acre? ... well...
No one ever accused me of being stupid, and don't assume I don't still have an eye towards how I can make millions of dollars quickly by growing hemp
Along the way, if you are constructing your own diet for feed composition for the birds, including other whole grains is always good, up to the recommended limits. Pay attention to the amino acid profiles and fat % of the various components, and compare to what is generally used for birds.
Wheat, sorghum (I grew ~3 acres of sorghum for the birds this year), amaranth, sunflowers!!! All very good sources of protein. Amaranth is REALLY good.
Each of those has their own amino acid profiles and recommended % maximum for chicken feed, shouldn't be too hard to figure out with some google searching of each grain, and to find some studies on the effects of including each in their diet.
Some (many?) actually offer this feed in separate feeders so the birds can pick and choose, as they see fit. This is known as volunteer feeding, the birds decide what they feel like eating, on the supplementary components, and is a great way to introduce new feed.
Like with most animals, I found the birds are wonderfully healthy on a very diverse diet - so the more stuff you can include (within reason, on the % max limits that are advisable), the better off they are! The goal is to make sure they are getting as wide a range of amino acid and healthy types of fat as possible, rich in all essential amino acids and omega 3's.
Also if you have backyard chickens, perfectly legal to feed them any-damn-thing-you-feel like.
The restrictions I mentioned w/ FDA are only for products intended to enter the retail market via USDA grading and certifications.
SO unless you have an actual egg dealer license (like we have) and are selling to restaurants, or something, do whatever floats your boat!
