Where do I go to analyze part or all of a plant for nutritional value?
Is there a lab that will test it for me or have most plants already been tested for nutritional value. Thanks for any help.

Most forage plants will be listed on the likes of Feedipedia. Failing that, the dung out the back of your stock will tell you a lot

I should have been more specific but was considering turning the seeds of some so-called invasive weeds into feed for fowl and possibly livestock.

"Suck it and see" is possibly my best advice. Seeds are usually the best parts of the plant - if the seeds are designed to be eaten to aid dispersal. Some aren't so good or even quite toxic, but that isn't difficult to find out

I just started researching it a little more and with the thought in mind of each seed having a specific dominant nutrient..... Would it be a possibility of combining a lot of weed's seeds(that most people spray to get rid of) to make a perfect feed.........

Possibly, although if you're feeding it to fowl then there's a good chance the seed will need rendered unviable by some means. Otherwise you may as well combine, clean and drill the seed into the ground; their rather primitive intestinal tract is very good at seed transfer, largely responsible for the regeneration of our native plants in NZ

So would it change its structure enough to grind it to a powder, and reclump it as they do with commercial grain feed. Wouldn't be that hard to make a machine to do it as far as effort goes. But I think the harder part would supplementing for essential nutrients that you couldn't find in your weeds(unwanted plants).
