Brewer’s Yeast for Laying Hens: Natural Nutrition for Better Eggs and Health

Brewer’s yeast (Saccharomyces cerevisiae) is a nutrient-dense feed additive derived from the beer brewing process. Widely used in modern poultry nutrition, it provides B-complex vitamins, high-quality protein, essential amino acids, minerals, and prebiotic components that support laying hens’ productivity and well-being.

Key Benefits

Improve Egg Production and Egg Quality

Supplementing layer diets with brewer’s yeast helps optimize nutrient utilization and supports consistent egg production. Its nutrient profile contributes to stronger eggshells and improved internal egg quality, including albumen height and yolk condition.

Enhance Gut Health and Immunity

Brewer’s yeast contains beta-glucans and mannan-oligosaccharides (MOS), which promote a healthy gut microbiome and support the immune system. Better gut health results in higher feed efficiency and reduced susceptibility to enteric pathogens.

Support Feather Condition and Overall Vitality

Rich in amino acids and trace minerals, brewer’s yeast helps maintain feather integrity and general body condition — visible signs of a healthy flock.

Reduce Stress and Improve Feed Conversion

B vitamins in brewer’s yeast aid metabolic processes and help birds cope with stressors such as heat, transport, or crowding — often improving feed-to-egg conversion ratios.

Recommended Usage

Typical inclusion rates range from 1% to 3% of the total feed, depending on the product form (deactivated yeast, live yeast, or yeast cultures) and flock needs. Work with an equine nutritionist or poultry veterinarian to determine the ideal dosage for your operation.
