Brewers Yeast 1kg


Available in 1kg Bags



The B complex vitamins in brewers yeast include B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B9 (folic acid), and H or B7 (biotin).

These vitamins are known to help break down carbohydrates, fats, and proteins, which provide energy. The B vitamins also maintain the muscles used for digestion and will help keep your horse’s coat, skin, eyes and liver healthy. Vitamin B1 Thiamine is specific for helping to support and maintain the nervous system, which is why horse owners use brewers yeast to help with nervous, over-exciteable or anxious horses.

Tests conducted over several years show that adding yeast supplements to your horse’s feed aids in the digestion of fiber. Research suggests the metabolites, which are produced during the fermentation process, increase the activity of bacteria in the horse’s hind gut. This enables more dry matter from a horse’s forage diet (hay or pasture) to be broken down, which results in a greater absorption of vital nutrients.

One of the most significant effects of adding yeast to equine rations is the ability to help stabilize the hindgut (cecum and colon) bacterial populations and as a result, also increases nutrient digestibility. Components of the yeast cell wall prevent the colonization of pathogenic microorganisms in the gut, improve the percentages of useful microorganisms in the intestinal tract, boost immune function and strengthen the structure of the gut wall. Yeast also stimulates the growth of bacteria that utilize lactic acid, which helps to lower lactic acid levels in the hindgut, and increases the numbers of bacteria that are responsible for the fermentation of fibre. A healthy, stable hindgut is imperative for horses to remain in good condition and prevent disorders such as colic, laminitis and other metabolic syndromes. Many performance horses are fed high starch diets (sweet feeds), and these feeds can cause hindgut acidosis (drop in pH), which often dramatically shifts the microbial populations in the hindgut, causing a disturbance. When this happens, the entire hindgut environment is negatively affected, and the products of microbial fermentation (volatile fatty acids, ammonia, lactic acid) are produced in different proportions and concentrations than what is considered normal. Colic and laminitis can follow an episode of acidosis, and this may be occurring on a sub clinical level in certain individuals every time they are fed a meal high in starch. Studies have shown that when yeast is added to the ration it can help prevent rapid changes in the intestinal ecosystem when high starch diets are fed.
