I should start out by saying that I've had goats for all of 5.5 months now...but that doesn't make me as inexperienced as I sound. Whenever I start a new project, I read widely before diving in, so I've worked my way through Storey's Guide to Raising Dairy Goats, Raising Goats Naturally, Natural Goat Care, and The Goat Care Handbook, plus lots of websites on the topic. I also resolved from the beginning not to feed my goats grain, so have instead been keeping them healthy on a seasonally varying ration based on grazing, hay, foraging trips to honeysuckle patches and oat leaves, carrots, alfalfa pellets, and sunflower seeds, plus kelp and minerals.
Which is a long way of saying that this is the book I wished I'd had when I got started. Tate walks you through a widely varying array of potential feeds you can grow or collect for your goats, along with a list of what you really shouldn't be feeding to your herd. She included sections on sprouting grains and growing them all the way to "fodder" also, both options of which are both better for the health of your herd than the dried seeds if you must feed grain. Tate also offers advice on drying a wide range of weeds and herbs to make your own mineral mix, and even covers small-scale methods of harvesting hay.
Overall, while Tate's short book obviously isn't the be-all and end-all on the subject, it's an eye-opening edition that should be part of your goat-keeping library if you want to move away from simply scooping up some sweet feed for your caprines to dine on each morning.
