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.
Diets are carefully balanced to meet all of the cowâs nutrient requirements for pregnancy, milk production and growth (if she has not yet reached her mature weight). A lactating cow will consume between 18 and 25 kg of dietary dry matter each day, depending on how much milk she is currently producing. Cows have access to feed and water at all times, except during milking (2 or 3 times per day). On farms with voluntary milking systems, the cows may receive a small amount of grain each time they enter the milking stall (4-8 times per day).
