I think we can all come to a consensus that horses are better off without grains and I am now looking into pros and cons of replacing the daily (and tiny - 0.5kg) portion of whole oats my boy gets with a bucket of alfalfa pellets. He gets ad-lib grass hay 24/7 (and unlimited pasture time in summer), is a good doer and has a moderate workload (beginner level SJ training, trail riding, groundwork) 4-5 times a week, and the oats, which are a traditional feed around here, were for mixing in his supplements. I tried unmolassed sugar beet pulp, but he didn't really like it, so what about alfalfa? Is there a possibility that it may throw him off phosphorus - calcium balance, and, if so, how to supplement the needed phosphorus? He wouldn't be getting more than 1kg alfalfa pellets a day anyway. Also, is alfalfa an adequate energy source in case of harder training?
Thanks in advance! :)
