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.
Following are some suggestions that should help with the situation. Estimate hay needs. A cow can eat 25 to 30 pounds of hay a day and waste a couple of more pounds. This adds up to 27 to 32 pounds per day per cow. Allow about half this amount for weanling calves and about threeâquarters for yearlings. Plan to feed until April 1.
