JMHO, --
when feeding "what I can grow"....
I feed kale, collard [especially yellow cabbage collard] corn stalks [green and dried] Jerusalem artichoke, root, and stalks [green and dried.] Sunflower seed [whole in the shell] , and sunflower stalks [green and dried] Carrots [fresh with tops, and roots stored in sand] , and sugar beets. I also feed all household food scraps, [except avocado, and citrus] I feed the weeds removed from the garden , and vegetable plants removed from the garden [except potato, and tomato ] when feeding what I grow, I also provide/ buy sheep mineral supplement.
If you really want to feed "what you can grow" you should do quite a bit of research, - I would start by purchasing the Book,
"Keeping Poultry and Rabbits on Scraps" [

This book was authored by people who "actually" had extensive experience using the methods presented...
- First issued in 1941, when the national crisis [in England] made it essential for every scrap of kitchen waste and spare time to be used for increasing the nation's food resources, this book enabled the meagre official wartime rations to be supplemented in thousands of homes by a regular supply of eggs and meat, at a minimum of trouble and expense.
**Disclaimer.. feeding what you grow is not as easy as feeding pellets, and--it is very time consuming.. -- it is difficult, and takes a lot of experience, to get growth rates even close to what can be achieved with "commercially produced pelleted feed". Part of the problem is all of the water in "grown feed" . Rabbits will eat a much larger volume of feed to get the needed nutrition. Rabbits raised on fresh vegetable material will have much larger stomach areas. IE: "paunch".
