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.
As a rule of thumb, a cow will eat 2 to 2.5 pounds of hay per day for each 100 pounds of body weight (about one 30- to 40-lb. bale per day). If you feed grain, the usual is 16% dairy ration, which will balance well with most pasture or hay. Another rule of thumb is to give 1 lb. of grain for every 3 lbs. of milk.s a rule of thumb, a cow will eat 2 to 2.5 pounds of hay per day for each 100 pounds of body weight (about one 30- to 40-lb. bale per day).
