The contribution of digestible and metabolizable energy from high fiber dietary ingredients is not affected by inclusion rate in mixed diets fed to growing pigs

Fiber in feed ingredients used in diets for pigs is mainly used for energy, which is synthesized by microbes in the hindgut of the pig and absorbed in the form of short chained fatty acids. To estimate the energy that a pig can obtain in a particular fibrous ingredient, a digestibility experiment is usually conducted and the digestible energy (DE) and the metabolizable energy (ME) in the ingredient is determined. However, it is not known if the obtained DE and ME values are accurate for all inclusion rates of the feed ingredient in diets.

There are two reasons that differing inclusion rates of high fiber ingredients in diets fed to pigs might result in variable DE and ME values. Because energy from dietary fiber is obtained via hindgut fermentation, there may be a saturation point in the fermentation capacity in the hindgut of growing pigs. In addition, increasing dietary fiber increases the passage rate of feed through the digestive tract and thus reduces time for fermentation. However, it is not known if these potential issues affect the DE and ME in fibrous ingredients fed to pigs. An experiment was conducted to determine effects of inclusion rate of four commonly used high fiber dietary ingredients on the concentration of DE and ME by growing pigs.

Phosphorus digestibility in corn, corn co-products, and bakery meal fed to growing pigs

With the prices of cereal grains rising, opportunities to reduce feed costs by using alternative ingredients are being explored. One source of alternative feed ingredients is co-products from the use of corn in the production of food for humans. Only limited published information is available on the digestibility of phosphorus in corn co-products derived from the human food industry.

Phosphorus from plant sources is often bound to phytate, which decreases the availability of the phosphorus to the pigs because pigs do not produce the enzyme phytase. The addition of microbial phytase to diets containing corn and soybean meal increases phosphorus digestibility in these ingredients. However, no data have been published on the effect of adding phytase to diets containing hominy feed, bakery meal, corn gluten meal, corn gluten feed, or corn germ meal.

Therefore, an experiment was performed to determine the apparent (ATTD) and standardized (STTD) total tract digestibility of phosphorus in hominy feed, bakery meal, corn gluten meal, corn gluten feed, and corn germ meal, and to compare these values to the values obtained for corn and DDGS. The effect of the addition of microbial phytase to the diets on the digestibility of phosphorus in the experimental ingredients was also measured.

Digestibility of amino acids in corn, corn co-products, and bakery meal fed to growing pigs

Rising costs of traditional swine feeds are causing many producers to look for alternative feedstuffs to deliver nutritional value at a lower cost. The corn milling and fermentation industries, and the human food industry, create co-products which can be fed to livestock. One of these, distillers dried grains with solubles (DDGS), has been found to be suitable for inclusion in swine diets up to 30%. Other co-products have not been as extensively studied. This experiment was performed to measure the apparent (AID) and standardized (SID) ileal digestibility of crude protein and amino acids in corn gluten meal, corn gluten feed, corn germ meal, hominy feed, and bakery meal in growing pigs and to compare these values to the values observed for DDGS and corn.
