Okay so I understand stocking rate and aums, but I'm a little confused. I'm from montana where you get pretty good snow cover from November till early march or later, when calculating how many animals your land can support for a year do you include those winter months even though you feed hay and supplement all winter due to snow cover and low protein in grass or do you just calcualte it for those growing month in the spring, summer, and fall. I used our nrcs aum calculator to figure out how many heifers my parents could support on there 20 acres but I'm stumped because of this. Some answers if you can. Thanks!
