I was trimming one of my senior does hooves tonight (7 yrs old, due in April) and noticed her joints were creaky. Is this likely attributable to boron deficiency? We have free choice Southern States beef minerals and also their sheep minerals with zinpro out for the girls. I’m pretty sure I’ve read that you can give borax for boron deficiency but for some reason the search function isn’t working for me. Would the boron be left out free choice like the mineral mixes or is it made into a solution and drenched? If drenched, is there a particular dose?
