Determination of amino acid digestibility in soybean meal from different regions of the United States and fed to pigs

Soybeans grown in the northern United States are exposed to fewer growing days and hours of sunlight than soybeans grown elsewhere in the U.S. As a result, soybeans grown in the northern U.S. fix less nitrogen, and have a lower concentration of crude protein, than other U.S. soybeans. However, the concentrations of particular amino acids, particularly indispensable amino acids, are more important for the purposes of diet formulation than the concentration of crude protein. The concentration of amino acids in soybeans grown in different parts of the U.S. has not been determined.

The amount of amino acids in soybean meal that are available to the pig also depends on digestibility, but no research has been conducted to compare the digestibility of amino acids among soybean meal produced in different regions of the U.S. Therefore, an experiment was conducted to compare the standardized ileal digestibility (SID) of amino acids and the concentration of SID amino acids in soybean meal produced in different regions within the United States and fed to growing pigs.

Effects of production area and microbial phytase on the apparent and standardized total tract digestibility of phosphorus by growing pigs

The area in which soybeans are grown is known to affect various aspects of the chemical composition of soybean meal produced from those soybeans. However, it is not known if there is a difference in the concentration of phytate, and therefore in phosphorus digestibility, among soybeans from different growing areas. Therefore, an experiment was conducted to determine the concentration of phytate and the apparent (ATTD) and standardized (STTD) total tract digestibility of phosphorus in soybean meal produced from soybeans grown in four different areas in the United States. A secondary objective was to determine the effect of microbial phytase on STTD of P in soybean meal from each of the four areas.

Concentrations of nitrogen-corrected apparent metabolizable energy and amino acid digestibility in soybean meal from Argentina, Brazil, China, Thailand and the United States fed to broilers

The nutritional value of soybean meal from different sources may vary due to differences in processing techniques and environmental conditions such as growing areas, soil type, and variety of soybeans. The Philippines import soybean for livestock feed from many different countries. However, the nutritional quality of soybean meal from these different origins has not been compared. It is important for producers formulating diets in the Philippines to know whether the same values can be used in formulations for all sources of imported soybean meal. Therefore, two experiments were conducted to determine the concentrations of apparent metabolizable energy (AME) and nitrogen-corrected apparent metabolizable energy (AMEn), and the standardized ileal digestibility (SID) of amino acids by broilers fed soybean meal from Argentina, Brazil, China, Thailand, and the United States.

Concentrations of digestible, metabolizable, and net energy in soybean meal produced in different areas of the United States and fed to pigs

One factor that affects the chemical composition of soybeans and soybean meal is where the beans were grown. For instance, soybeans grown in the northern United States contain less crude protein than soybeans grown further south. As a result, soybean meal produced from beans grown in the Northern United States often contain less crude protein than soybean meal produced from beans grown further south. However, less is known about how the concentrations of digestible (DE), metabolizable (ME), and net (NE) energy differs among meals produced from soybeans grown in different areas of the U.S. Therefore, an experiment was conducted to determine the digestibility of energy and concentrations of DE, ME, and NE in soybean meal produced from soybeans grown in different areas of the U.S. and fed to growing pigs.

Performance and carcass characteristics of growing and finishing pigs fed diets containing high protein or conventional canola meal

Canola meal can be used as a source of protein in swine diets, but conventional canola meal contains less protein than soybean meal. In recent years, new varieties of canola have been developed with seeds that contain more protein and less fiber than conventional canola seeds. The meal from these new varieties of canola has a protein content similar to that of soybean meal.

Previous research at the University of Illinois demonstrated that diets containing at least 30% high protein canola meal (CM-HP) or conventional canola meal (CM-CV) could be fed to nursery pigs without reducing growth performance. It has not yet been determined how much soybean meal can be replaced by conventional or high protein canola meal in diets for growing-finishing pigs without affecting growth performance or carcass characteristics. Therefore, an experiment was performed to determine the optimum inclusion rate of high-protein and conventional meal in diets fed to growing and finishing pigs.
