Brewers yeast contains a multitude of essential nutrients which are highly available to animals when fed as a part of their diet. A yeast cell is almost one-half high quality protein including all the essential amino acids. During fermentation, yeast absorbs other nutrients from its environment, especially minerals including significant amounts of chromium and selenium which become bound to its proteins in a process known as chelation. These essential minerals are more easily absorbed for use by the animal than inorganic mineral compounds. Animals fed brewers yeast generally exhibit increased stamina and resistance to stress even under the strain of repeated showings and travel because of improved nutrient intake.
Yeast also assists in improved digestive efficiency.
Its nutrients feed and nourish the digestive organisms that do the work of converting feed into nutrition for the animal. It helps to assure that the microflora are working at peak levels. Improved digestion means the animal will have less chance of digestive upset and will show better feed conversion. More nutrients are available to sustain growth and development. Like a star athlete, a show animal must meet special nutritional needs to compete and win in the show ring.
