PRECISION MICROBES - CALVES

Precision Microbes® is proudly developed and manufactured in Ireland in a FAMI-QS certified manufacturing facility. Ireland is internationally recognised for excellence in animal nutrition and microbiome research, providing confidence that Precision Microbes® is manufactured to the highest standards of quality, safety and consistency.

Precision Microbes® is more than a probiotic. It combines live beneficial probiotic bacteria and supportive postbiotic metabolites in a unique liquid formulation designed to rapidly support the developing calf microbiome. Unlike many powders and pastes containing freeze-dried bacteria, the liquid formulation delivers live acid-adapted microbes together with their beneficial metabolites for rapid action in the gut.

More than 70% of the immune system is associated with the gut, making early gut health fundamental to calf health and performance. Precision Microbes® has been specifically formulated to support the developing gut microbiome, helping improve digestive health, nutrient utilisation, immune resilience and early-life growth. It is ideal from birth through to weaning and can be incorporated into both whole milk and milk replacer feeding programs.

Yes. Precision Microbes® forms an excellent part of an evidence-based calf gut health and cryptosporidiosis management program. Research from the University of Glasgow demonstrated that calves receiving Precision Microbes® experienced a reduced prevalence and severity of cryptosporidiosis, together with higher voluntary milk intakes and improved average daily gain compared with untreated calves. Precision Microbes® is not a treatment for cryptosporidiosis, but it provides valuable nutritional support to help maintain gut health and resilience during periods of challenge. For farms experiencing significant cryptosporidiosis pressure, our team can help develop a comprehensive calf health program tailored to your operation.

Yes. Precision Microbes® can be safely used alongside electrolytes, antibiotics and other calf supplements. Unlike many conventional probiotics, its beneficial postbiotic metabolites remain active, making it particularly valuable before, during and after antibiotic treatment when supporting gut recovery is critical.

The recommended program is 30 ml daily for the first 30 days of life ("30 for 30"), when establishing a healthy gut microbiome is most critical. However, calves continue to benefit from supplementation through to weaning, particularly during periods of stress or increased disease challenge. For calves experiencing digestive upset, the feeding rate can be increased in accordance with the product recommendations.

Absolutely. Precision Microbes® has been specifically formulated to complement, not replace, a quality milk additive program. While complete milk additives are designed to provide essential vitamins, minerals and, where included, support against protozoal diseases such as coccidiosis, Precision Microbes® focuses on a different area—establishing and supporting the developing gut microbiome through a unique combination of live probiotic bacteria and postbiotic metabolites. Many producers successfully feed Precision Microbes® alongside a complete milk additive to provide both comprehensive nutrition and targeted gut health support, particularly during the critical first weeks of life or periods of digestive challenge.

Improved Digestive Health: Precision Microbes supports optimal digestion, nutrient absorption, and gut function. Enhanced Immunity: Helps bolster the calf’s immune system, reducing susceptibility to diseases and infections. Scour Reduction: Clinical trials demonstrate fewer incidences and severity of digestive upsets, promoting overall calf health. Better Growth Rates: Contributes to faster growth and development, leading to healthier and stronger calves.
