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.
How much milk does a cow give each day? Most dairy cows are milked two to three times per day. On average, a cow will produce six to seven gallons of milk each day. What do cows eat? A cow that is milking eats about 100 pounds each day of feed, which is a combination of hay, grain, silage and proteins (such as soybean meal), plus vitamins and minerals. Farmers employ professional animal nutritionists to develop scientifically formulated, balanced and nutritious diets for their cows.
