the aim of this study was to determine the effect of yeast culture (saccharomyces cerevisiae sc 47) addition in the diet of dairy cows on their rumen fermentation and milk production. animals received a diet tmr based on good maize silage with a higher dry matter content (14 kg), 14 kg of lucerne-grass haylage, 5 kg of crushed ears of maize, 5 kg of beet pulp silage, 3 kg of crimped wheat, 2 kg...

the effect of yeast culture (saccharomyces cerevisiae) supplementation on laying hen diets was tested against flavomycin supplementation during 12 weeks, using 112 brown bovans laying hens, 52 week-old, divided into 7 equal groups fed on a basal diet containing 18.8% crude protein and 2810 kcal/kg me (metabolizable energy) feed. three groups were supplemented with 3 different levels of commerci...

Introduction: The purpose of this study was formulation and preparation of a proper culture medium for Saccharomyces cerevisiae var. boulardii with molasses and animal serum. Methods: A fully-crossed factorial design contain 5%, 10% and 20% of molasses (M) with 0, 1% and 5% animal serum (S) was used in this study. The pH of all culture medias were adjusted to 5.6 with acetic acid. The seed was ...

In this study, twenty-five whey samples collected from dairy industries in the city of Isfahan. The sampleswere cultured on malt extract broth (MEB) and yeast extract glucose chloramphenicol agar (YGCA) media.Eleven yeast strains (designated M1 to M11) were isolated from the culture. The strains were identified bytheir morphological and physiological properties. Betagalactosid...

Sixty Holstein cows were assigned to two treatments at 21 d before calving and were group-fed a prepartum diet with or without yeast culture. After parturition, cows were individually fed one of five treatments for 140 d: 1) 21% forage neutral detergent fiber (NDF) without yeast culture, 2) 21% forage NDF with yeast culture, 3) 17% forage NDF without yeast culture, 4) 17% forage NDF with yeast ...
