Soybeans

Nitrogen-corrected true metabolizable energy, standardized amino acid digestibility, and digestibility of phosphorus in a new variety of soybeans fed to chickens

The improvement of yield or oil content in soybean seeds, mainly through genetic modification, has often resulted in a decrease in protein concentration. However, a new genetic technology patented as Photoseed was used to develop a new variety of soybeans. By modifying genes involved in biosynthesis and storage of lipids, it was possible to increase the accumulation of lipid droplets and increase carbon capture. This resulted in soybeans that contain more oil, without negatively affecting crude protein concentration, compared with conventional soybeans. There is, however, no information about the nutritional value of the soybean meal produced from the Photoseed variety of soybeans. Therefore, the objective of this study was to test the hypothesis that nitrogen-corrected true metabolizable energy (TMEn), standardized amino acid (AA) digestibility, and apparent ileal P digestibility are not different in a soybean expeller (SBE) produced from a new variety of Photoseed soybeans compared with SBE produced from conventional soybeans.

Amino acid digestibility in a new variety of soybeans fed to growing pigs

Soybean meal is the principal amino acid (AA) source in diets for pigs, and it is recognized that the AA profile of soybean meal is superior to that of other oilseed meals. However, new varieties that have different characteristics are sometimes developed and an example of such a new variety is the Photoseed variety of soybeans that captures more carbon and sunlight leading to a more nutrient rich ingredient and a reduced footprint from crop production. There is, however, no information about the nutritional value of the soybean meal produced from the Photoseed variety of soybeans. Therefore, the objective of this research was to test the hypothesis that the apparent ileal digestibility (AID) of crude protein (CP) and AA, and the standardized ileal digestibility (SID) of CP and AA are not different in soybean meal produced from Photoseed soybeans compared with control soybean meal when fed to pigs.
