Feed Consumption and Conversion A pig will eat approximately 282 kg of feed in its lifetime. It takes approximately 3.7 kg of feed to produce 1 kg of pork. Nutrition Pigs eat nutritionally balanced diets made up of corn and soybean based feed mixed with vitamins and minerals. Mechanized feeding systems are used on most hog farms. These systems are quicker and easier for the farmer to feed large numbers of pigs and provide the pigs with the proper amounts of feed for their nutritional requirements.
Fresh water is always available for pigs to drink.
The average water requirement for a market hog varies from 5 to 8 litres per day.
