Hybrid rye may replace corn in diets for growing-finishing pigs without influencing most carcass traits, but feed intake may be reduced at high inclusion rates

Hybrid rye may replace a portion of barley or wheat in diets for growing and finishing pigs with minimal impact on growth performance or carcass characteristics, but at very high inclusion rates in finishing diets, feed intake may be reduced if hybrid rye replaces wheat. However, limited published data exist for effects of feeding hybrid rye to growing-finishing pigs in place of corn. Therefore, an experiment was conducted to test the hypothesis that average daily gain (ADG) and carcass characteristics will not differ when hybrid rye partially replaces corn in diets for growing-finishing pigs.

Digestibility of P and concentrations of digestible and metabolizable energy in high-oil corn fed to growing pigs

Conventional breeding of corn has generated a new variety (i.e., high-oil corn; Byron Seeds LLC, Rockville, IN), which is believed to contain more oil and phosphorus than conventional corn. Because of the increased oil, it is possible that high-oil corn contains more digestible energy (DE) and metabolizable energy (ME) than conventional hybrids, but this hypothesis has not been experimentally verified. Inclusion of microbial phytase in diets for pigs usually improves digestibility of P because phytase hydrolyzes the ester bond that binds P to the phytate molecule in corn. However, there are at this point no data for effects of adding phytase to diets containing high-oil corn and no data to demonstrate the nutritional value of high-oil corn. Therefore, an experiment was conducted to test the hypothesis that the standardized total tract digestibility (STTD) of P, as well as concentrations of DE and ME in high-oil corn are greater than in conventional corn. The second hypothesis was that inclusion of microbial phytase to diets improves the STTD of P in corn sources.

Digestibility of amino acids in high-oil corn product fed to growing pigs

Corn is a cereal grain that is commonly used as a feed ingredient for swine diets due to its excellent palatability, and it can easily be grown on a wide range of environmental conditions. Conventional breeding of corn has generated a new variety (i.e., high-oil corn; Byron Seeds LLC, Rockville, IN), which is believed to contain more oil and crude protein (CP) than conventional corn. It is, therefore, possible that this high-oil corn may be comparable to other cereal grains and may serve as alternative to corn for pigs. However, there are at this point no data to demonstrate the nutritional value of high-oil corn. Therefore, an experiment was conducted to test the hypothesis that the standardized ileal digestibility (SID) of amino acids (AA) in high-oil corn is greater than in conventional corn.

Digestible and metabolizable energy in corn- or sorghum based diets may be improved by addition of a xylanase-cellulase enzyme mixture

Exogenous carbohydrases can be used in diets for pigs to increase digestibility of dietary fiber and energy in cereal grains and cereal co-products. The three main fibers in cereal grains and cereal co-products are arabinoxylans, cellulose, and mixed-linked beta glucans. The fermentability is different among these three types of fiber. Energy digestibility is often improved if xylanase is added to wheat-based diets, whereas positive responses to xylanase in corn-based diets have been difficult to demonstrate, indicating that fermentation of dietary fiber differs among ingredients. However, there is less information about effects of carbohydrases on digestibility of fiber and energy in sorghum-based diets. Therefore, an experiment was conducted to test the hypothesis that xylanase and cellulase improve the digestibility of energy and total dietary fiber in diets based on corn or sorghum with addition of high fiber co-products.

Digestibility of amino acids, fiber, energy, and concentrations of digestible and metabolizable energy in conventional and extruded yellow dent corn, wheat, and sorghum fed to growing pigs

Extrusion of cereal grains may be used to improve nutrient digestibility in cereal grains because addition of heat and pressure in combination with addition of moisture during the extrusion may gelatinize the starch, which results in an increase in starch digestibility. It is also possible that AA and energy digestibility are increased by the extrusion, but data to verify this hypothesis have not been published. Therefore, the objective of these experiments was to test the hypothesis that the ileal digestibility of AA and starch and the apparent total tract digestibility (ATTD) of ADF, NDF, and GE as well as the concentrations of DE and ME in corn, wheat, and sorghum are increased by extrusion.
