Performance, intestinal microflora, and blood constituents in finishing turkeys fed diets supplemented with dietary mannan oligosaccharide and live yeast.

This study was designed to evaluate the effects of dietary mannan oligosaccharide (MOS) and Saccharomyces cerevisiae (SC) in finishing turkeys’ diets on performance, intestinal microflora, duodenal viscosity and pH, and blood constituents. A total of seventy-two, Big6, 10-week-old, male poults were divided into three dietary treatments and eight replicate pens per treatment. Treatments including the following: 1. basal diet (control - C, no additive), 2. addition of MOS 1 g per kg basal diet, and 3. SC 1 g per kg (strain SC47, 300 × 10 10 CFU/kg) basal diet. The treatments did not affect body weight, duodenal viscosity, and pH. The daily feed intake (P 0.05).
