Fig. 1From: Effects of different forms of yeast Saccharomyces cerevisiae on growth performance, intestinal development, and systemic immunity in early-weaned pigletsThe morphologies of different forms of yeast preparations. Different forms of yeasts, including LY (a), HKY (b), and SFY (c) were resuspended and stained with methylene blue, respectively. The samples were examined with a Zeiss AxioScope A1 microscope (Carl Zeiss) at 400 × magnification under visible light. Abbreviations: LY, live yeast; HKY, heat-killed whole yeast; SFY, superfine yeast powdersBack to article page
