Nutritional value of Saccharomyces cerevisiae biomass. Study in generations of rats

Não consta resumo na publicação.The biological value of the proteins of Saccharomyces cerevisiae grown in sugar cane molasses was studied in rats during 3 generations. The animals were fed two levels of yeast protein either 10% or 25% and compared with casein fed controls. In the first generation the PER and body weight were significantly lower for the animals receiving the yeast in their diet. In the 2rd and 3rd generation the growth was retarded even more in relation to what had been observed for the first one, specially at 10% protein level. A decreased male fertility was also observed at litter born from rats fed either 10% or 25% protein. The digestibility for casein was 90% and 80% for single cell protein
