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.
When feeding the same forage, cows that weigh 1,300 pounds will consume more on a daily basis compared to lighter weight cows that weigh 1,100 pounds. In addition, cows that are lactating will consume more feed than cows that are not lactating.
