Effects of a xylanase and an emulsifier in diets with dried yeast on nursery pig performance

An abstract of a study by Hesse et al that examines the effects of a xylanase and an emulsifier in diets with dried yeast on nursery pig performance is presented. The inclusion of DY up to 10% of diet did not affect pig performance from d 0-14. In both experiments, increasing levels of DY reduced (linear, P < 0.05) the overall (d 0-42) ADG (Exp. 1: 441, 424, 409, 411 g/d; SEM = 18; and Exp. 2: 502, 491, 478, 464 g/d; SEM 13, for 0, 2.5, 5, and 10% DY, respectively). In conclusion, DY may be used up to 10% of the diet to replace fish meal and soy protein concentrate without affecting pig performance during the first 14 d postweaning. Inclusion of XY+EM improves nursery pig performance, whereas XY alone did not.
