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.
All cattle will eat primarily between 1.6% to 3.0% of their body weight per day (on a Dry-Matter [DM] basis), depending on the quality of the forage they are consuming.Dry cows, heifers, steers and bulls tend to eat around 2.0% of their body weight per day, on average.ig cows eat more than small cows, and thin cows will eat more than fat cows. Also, as you will notice in the related question posted below, moisture content in the feed and the quality of the feed will affect how much an animal will eat per day. Usually, the higher the moisture content, the more a bovine will eat.
