I can't find a straightforward answer to goat feeding! We have a 10 month old Pygmy, an 8 month old mini Nubian & an 18 month old Boer/Nigie cross (all does). What, exactly, are we supposed to feed them? We've been feeding them alfalfa, with a grain mix for treats. We recently brought in a buck to breed with the Pygmy & Boer/Nigie cross. What do we start feeding them after they are pregnant? I even got a goat book & it's not specific on feeding! & every search I do online gives conflicting information! I'm so confused! Help! Thank you!
