Whey is a by-product from milk processing used in diets for young pigs. Lactose is an excellent source of energy for pigs after weaning. It also contains high levels of sodium. Salt should be reduced to 0.25 percent of the diet when whey is used. Fat is often used to increase the energy content of swine feed.
Animal fat is available to many Alabama swine producers.
Research has shown improvements in pig and sow performance from adding 3 to 5 percent fat in the diet.
