Whether putting food in the refrigerator, the freezer, or the cupboard, you have plenty of opportunities to prevent foodborne illnesses. One of the basics of food safety is cooking food to its proper temperature.
I personaly always figured around 25lbs of hay per day for a average size cow when i was putting up hay. Alot of that of course they can get if pasture is available/accessable. Multiply that by your number of cows x average days you actually have to feed.
Average cow weight x hay DMI (% of cow weight, as a decimal) = DMI/d1300 x .025 = 32.5 lb of hay DMI/day Step 2 â Adjust Daily Hay Disappearance Per Cow for Waste In addition to what cows consume, there will be some waste associated with feeding hay and this must be accounted for when calculating winter feed needs.
