The Effect of Supplemental Probiotics and Spray-Dried Egg Proteins on Piglet Growth Performance Characteristics

Abstract

This study evaluated the use of a supplemental probiotic, containing spray-dried egg proteins and several different dried bacteria. The objectives of this study were to determine if the probiotic supplement affected growth performance of the piglets, fecal consistency, and the number of Escherichia coli and Lactobacillus species present in the feces. The supplemental probiotic was administered at three intervals with fecal samples being collected at four intervals. Weights were collected at five intervals. There were no differences (P > 0.05) in 21-day, weaning, nursery, or finishing floor weights between treatment and control groups. There were no differences (P > 0.05) in fecal scores in the farrowing house, nursery, or finishing floor between treatment and control groups. There were no differences (P > 0.05) in the number of Escherichia coli or Lactobacillus species present in the fecal material, between treatment and control groups, at all intervals measured.
