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.
Re: Average hay consumption. A cow needs about 3 per cert of its body weight in roughage a day, a 1000 lb cow needs 30 lbs of hay if it has no other source of roughage.
For example, if a grain cost $185/ton ($0.20/kg) and 25 pounds (11.4 kg) were fed per day, grain cost per cow per day would be $2.31. Feed Cost per Cow per Day. This is the cost of all feeds (grain + forage) fed to the cow each day.
