We have a pretty diverse mix in our pastures, including native species. I've found our goats also do better legumes and forbs with higher protein value, such as alfalfa, clover, birdsfoot trefoil - of course you might see what species are best in your region but looking at those factors might help! I have a longer list of our pasture species here: grazingwithleslie.com/grazing-meat-goats/qa-july20/
