Digestibility of amino acids in high protein corn fermented products fed to growing pigs

New sources of high protein corn co-products have been recently developed and may be included in diets fed to pigs. High protein corn fermented products have been evaluated in several economically important livestock species, but additional information is required with respect to the use of these products in pigs. Therefore, an experiment was conducted to test the hypothesis that the standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) in high protein corn fermented products and in the residual distillers dried grains and solubles (DDGS) is greater than in soybean meal (SBM).

Effect of SylPro yeast on growth performance and intestinal health of weanling pigs

SylPro enhanced torula yeast is a high protein feed ingredient derived from forestry by-products, and results from digestibility experiments indicate that SylPro yeast may be a great source of energy and digestible amino acids in diets fed to weanling pigs. Previous experiments further demonstrated that increasing levels of SylPro yeast resulted in increased feed efficiency of pigs, which is likely a result of a positive effect of SlyPro yeast on intestinal health and immune function of pigs. However, there are no data to demonstrate effects of SylPro yeast on the immune response of pigs. It is also not known if SylPro yeast influences pig performance and intestinal health similarly as conventional torula yeast. Therefore, an experiment was conducted to test the hypothesis that inclusion of SylPro yeast in diets fed to pigs improves growth performance and intestinal health. The second objective was to determine if there are differences between the two torula yeast sources in influencing growth performance and immune response of pigs.

Effect of microbial phytase on digestibility of phosphorus in seven sources of sunflower meal fed to growing pigs

The majority of P in oilseed co-products is bound to phytate; however, pigs do not synthesize adequate amount of endogenous phytate to liberate the P bound to phytate and the digestibility of P in sunflower meal, therefore is low. Values for ATTD and STTD of P in sunflower meal (SFM) without and with phytase have been reported, but there are no comparative values for the ATTD and STTD of P in sunflower co-products produced in different parts of the world. Therefore, the objective of this experiment was to determine the ATTD and the STTD of P in different sources of sunflower co-products, and to test the hypothesis that regardless of source, microbial phytase increases the digestibility of P in sunflower co-products fed to young pigs.
