Determination and prediction of digestible and metabolizable energy concentrations in byproduct feed ingredients fed to growing pigs

OBJECTIVE An experiment was conducted to determine digestible energy (DE) and metabolizable energy (ME) of different byproduct feed ingredients fed to growing pigs, and to generate prediction equations for the DE and ME in feed ingredients. METHODS Twelve barrows with an initial mean body weight of 31.8 kg were individually housed in metabolism crates that were equipped with a feeder and a ni...

Digestible and metabolizable energy of crude glycerol for growing pigs.

The apparent DE and ME values of crude glycerol for growing pigs were determined in 5 experiments using crude glycerol (86.95% glycerol) from a biodiesel production facility, which used soybean oil as the initial feedstock. Dietary treatments were 0, 5, or 10% glycerol addition to basal diets in Exp. 1; 0, 5, 10, or 20% glycerol addition to basal diets in Exp. 2; and 0 and 10% crude glycerol ad...

Alternative Feed Ingredients for Pigs

Largely due to the demand for grains for the bio-fuel industry, the cost of feed energy will increase worldwide. Therefore, alternative energy supplying pig feed ingredients should be explored, including distillers dried grains with solubles (DDGS), field peas, wheat shorts and liquid co-products from the bio-fuel and food industry. The inclusion of DDGS in diets is limited by the fiber concent...

Ileal Amino Acid Digestibility of Broken Rice Fed to Postweaned Piglets with or without Multicarbohydrase and Phytase Supplementation

Most of amino acid (AA) digestibility values for feed ingredients are obtained using pigs cannulated in the distal ileum. The ileal-cannulated pig model uses pigs older than six weeks due to difficulties related to implanting the T-cannula in distal ileum of younger pigs and complications during the post-surgical recovery. However, to properly formulate the diet of weaned pigs, the nutritive va...
