enhanced torula yeast

Effect of increasing levels of Sylpro yeast on growth performance and blood characteristics 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 valuable source of energy and digestible amino acids in diets fed to weanling pigs. As a consequence, it is believed that Sylpro yeast may be included in diets for weanling pigs at the expense of fish meal and other animal protein sources. Therefore, an experiment was conducted to test the hypothesis that increasing levels of Sylpro yeast improve growth performance and blood characteristics of weanling pigs.

Effect of inclusion of an enhanced torula yeast on growth performance, fecal score, and blood characteristics of weanling pigs

Digestibility experiments have been conducted to determine the nutritional value of an enhanced torula yeast derived from forestry by-products. Results of these experiments indicated that enhanced torula yeast has a greater digestibility of amino acids and P than fish meal, and a concentration of metabolizable energy that is not different from that in fish meal. Therefore, it is believed that the enhanced torula yeast can be included in diets for weanling pigs at the expense of fish meal and other animal protein sources. Therefore, the objective of this experiment was to determine the effects on growth performance, fecal score, and blood characteristics of including the enhanced torula yeast at the expense of fish meal and plasma protein in diets fed to weanling pigs.

Digestibility of phosphorus in enhanced torula yeast and fish meal fed to weanling pigs

An enhanced torula yeast was recently developed as a natural alternative protein source to fish meal and other animal proteins. This ingredient has a lower carbon footprint than other available yeast proteins because it is derived from forestry by-products. The enhanced torula yeast has an improved amino acid (AA) profile, a greater digestibility of AA than fish meal, and an energy value that is not different from that in fish meal. However, there are no data available about the digestibility values of P in this new ingredient. Therefore, an experiment was conducted to test the hypothesis that the values for apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) of P in enhanced torula yeast are not different from those in fish meal.

Amino acid and energy digestibility of an enhanced torula yeast and fish meal fed to weanling pigs

Yeast may be used instead of fish meal or other animal protein sources in diets for weanling pigs and there are several yeast proteins available. A newly developed enhanced torula yeast is derived from forestry by-products, and therefore, has a lower carbon-footprint compared with other yeast products. This enhanced torula yeast has an improved amino acid (AA) profile compared with traditional fermentation products, but at this time no data for the nutritional value of enhanced torula yeast fed to weanling pigs have been published. Therefore, 2 experiments were conducted to test the hypothesis that the AA and energy values of enhanced torula yeast is not different from that of fish meal. In Exp. 1, the apparent ileal digestibility (AID) and the standardized ileal digestibility (SID) of AA were determined, whereas Exp. 2 was designed to determine the concentration of digestible energy (DE) and metabolizable energy (ME) in both enhanced torula yeast and fish meal.
