Abstract
The Effect of Live Yeast and Yeast Extracts Included in Lactation Diets on Antimicrobial Susceptibility of Fecal Escherichia coli in Sows
Highlights
Supplementing live yeast and yeast extracts in sow diets has been researched due to the potential for a healthier/heavier piglet which may be more equipped to handle weaning stress, leading to improved nursery performance
A total of 27 sows (Line 241; DNA Genetics) were used in a study to evaluate the effect of feeding live yeast and yeast extracts to lactating sows on antimicrobial susceptibilities of fecal E. coli
Dietary treatments consisted of a standard corn-soybean meal lactation diet or a diet that contained yeast-based pre- and probiotics (0.10% Actisaf Sc 47 HR+ and 0.025% SafMannan; Phileo by Lesaffre, Milwaukee, WI)
Summary
Supplementing live yeast and yeast extracts in sow diets has been researched due to the potential for a healthier/heavier piglet which may be more equipped to handle weaning stress, leading to improved nursery performance. This report is a companion to another research report where we evaluated the effects of a live yeast and a yeast extract on sow and litter performance.[5]. The objective of this study was to evaluate the effects of feeding the live yeast Saccharomyces cerevisiae strain NCYC Sc 47 and a yeast cell wall fraction with concentrated mannan-oligosaccharides and β-glucans from Saccharomyces cerevisiae on the antimicrobial susceptibility of sow fecal E. coli
