Digestibility and nutrient intake in Mangalarga Marchador mares supplemented with Saccharomyces cerevisiae during aerobic training

Abstract

The study evaluated the effect of yeast supplementation on the digestibility and intake of nutrients of Mangalarga Marchador horses in training. Fourteen Mangalarga Marchador mares were divided into two groups: Probiotic (horses supplemented with 20 g of Saccharomyces cerevisiae daily) and Control. The diet consisted of commercial concentrate and roughage in the ratio of 50:50. The mares were trained for six weeks, Monday to Saturday, and the exercise performed daily alternating work on a treadmill and automatic walker. Nutrient digestibility was assessed using the indicator LIPE® (6 days) end fecal collection was performed for five days. Was analyzed DM, NDF, ADF, CP, GE, hemicelluloses and dry matter intake. There was not difference (P>0,05) in any of the variables analyzed. Supplementation with 20 g of Saccharomyces cerevisiae does not affect the digestibility and nutrient intake in mares Mangalarga Marchador submitted six weeks of aerobic training.
