Table 1 The positive influence of yeast supplementation on animal’s health, nutrition and performance [25]

Ruminants

Reduces lactate production or accumulation; Balance ruminal pH; Stimulate the growth of cellulolytic and fibrolytic microorganisms, increasing net fiber intake and digestion; Increasing the total ruminal microflora; Improve the health of the ruminant; Reduce methane emissions

Poultry

Modulate of intestinal microflora; Stimulate immune system; Inhibit the growth of pathogenic bacteria; Increase organic phosphorus utilization; Increasing the egg production and improve the internal egg quality of poultry birds; Improve feed intake; Reduce plasma cholesterol; Promote meat quality of poultry

Pigs

Improve the pig’s gut microflora balance; Proper maturation of the gut associated tissue; Modulate immune response reducing enteric pathogens; Reduce post-weaning diarrhea (PWD) symptoms in pigs; Exhibit growth promoting properties in weaning ang fattening pigs; Improve feed conversion efficiency

Horses

Ameliorates the dysfunction of horse’s ecosystem such as lactic acidosis, colitis, laminitis and enterotoxaemia; Increase in digestibility of diet nutrients; Enhances enzyme production in the hindgut

Aquaculture

Improve growth in juvenile and adult fish; Enhance survival rate; Positively modulate cellular innate immune system parameters; Stimulation of enzymatic antioxidative response of farmed fish
