Use of yeast (Saccharomyces cerevisiae) at the diet of lactating cows

Abstract

The dairy cattle in Brazil is an activity of economic and social importance, both for food and nature in the generation of income and jobs. Increased efficiency in milk production is related to the improvement of power. Thus, food additives, are used to improve animal performance, operating in controlling or modifying the rumen fermentation pattern, thereby preventing disturbances metabólicos.O microorganisms of interest in the use as feed additives for dairy cows has increased significantly in recent years. A group commonly used are yeasts, particularly Saccharomyces cerevisiae, identified as probably responsible for improvement in the rumen, with no effect on pH. So it was aimed to observe the influence of the use of yeast (Saccharomyces cerevisiae) in diets of lactating cows on the increased production of leite.Os data used in this study were derived from the Quilombo Farm, owned by Winston Frederick Adams Drumond. The property is located on Highway MG-154, 7 km in the city of Capinópolis, Minas Gerais. Cows were selected in Gyr cattle by the head coach of PO propriedade.Com order to increase the production of milk was added to the diet in the rumen specific live yeast Saccharomyces cerevisiae CNCM I-1077 (Levucell SC Farm of Lallemand, pack of 5 kg ), with inclusion of 50 g / animal / day, divided between the five day feeding schedule, 10 grams each. Showed an increase in milk production of animals supplemented with the yeast Saccharomyces cerevisiae.
