The inclusion of Saccharomyces cerevisiae Sc47 (Actisaf®) yeasts on piglets' feed and their influence on growth performance and nutrient utilization after weaning

 

Weaning as currently practiced represents one of the most critical periods in the raising of pigs. It is characterised by a diminution in feed consumption, leading to a state of severe anorexia, an increased sensitivity to digestive problems or microbial infections, and a slowdown of growth.

 

The change in the nutrient substrate also brings with it major modifications in intestinal function, influencing nutrient utilisation, metabolism or even protein synthesis. In addition, the digestive microflora, whose major function would seem to be to protect the digestive tract against invasion by enteropathogenic bacteria, undergoes major changes during weaning.

 

In the past these risks were reduced by the systematic application of sub-therapeutic doses of growth-promoting antibiotics in the feed. However, the risk of development of bacterial strains resistant to antibiotics led the EU to prohibit their use. Since then, the animal feed industries have been searching for alternatives capable of maintaining production levels and the health of the animals.

 

The Saccharomyces cerevisiae Sc 47 yeasts (Actisaf®), their cell wall fractions or extracted fractions (mannan oligosaccharides, β-glucans) would seem to be possible alternatives.
