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.
Feed represents the largest single cost (60 percent of total) in a cow-calf enterprise. The old adage, a penny saved is a penny earned never resonated more strongly. Science tells us that a 1300 lb. dry pregnant cow in good condition needs to eat about 27 lbs. of hay per day to maintain herself and grow her calf. But when farmers project the feed inventory they need for the winter, they may actually estimate their cows feeding needs at 35-40 lbs. of hay per day.
