ABSTRACT
Farahmand M, Dehkordi SK, Khorvash M, Mirzaei M., Effect
of live and cultured yeast supplements on intake, digestibility, growth, rumen
pH and metabolites in Holstein calves, Onl J Vet
Res., 25 (5): 370-375, 2021. We report
effects of live or cultured yeasts on feed intake, growth and rumen metabolites
in calves. Groups of 12 calves each were supplemented 4g/d live or cultured
yeasts from 3 to 72 days age weaned at 50 days. Controls were not supplemented.
Calves were monitored from 3rd to 72nd day of age for
feed intake, digestibility, body weight, skeletal growth, stools, rumen pH and
volatile fatty acids. We found no significant differences between controls and
calves given live or cultured yeasts in any measurement.
Keywords: Calves, Live yeast, Cultured
yeast, feed intake, digestibility, growth, Rumen volatile acids.
