4PRO™ MICROBIAL FORTE

Young livestock are born with an immature gastrointestinal tract that is rapidly colonised by beneficial microbes during the first days and weeks of life. Stress, dietary changes and environmental challenges can disrupt this process. Supplying a diverse probiotic blend early in life helps establish a balanced gut microbiome, supporting digestive health, nutrient utilisation, immune development and resilience during this critical period. Research indicates the greatest benefits are often observed during periods of stress or microbial imbalance.

Different probiotic species and strains perform different functions within the gastrointestinal tract. A diverse, complementary blend is more likely to support microbial diversity, colonise multiple ecological niches and maintain microbiome balance than a single strain alone. 4PRO™ MICROBIAL FORTE combines carefully selected bacteria and beneficial yeast at a high inclusion rate to deliver broad-spectrum digestive support during early life and other periods of stress.

The first three weeks of life are critical for establishing a healthy gut microbiome. While probiotics provide the greatest benefit during periods of digestive or environmental stress, including birth, transport, dietary transitions and weaning, continued supplementation throughout the milk-fed phase helps maintain microbial balance and supports digestive health, resilience, growth and early-life performance. 4PRO™ MICROBIAL FORTE provides the probiotic foundation for continuous microbiome support and is incorporated into products such as BEST-START™ THRIVE and EVERGREEN™ for convenient daily feeding throughout the milk-fed phase.

4PRO™ MICROBIAL FORTE delivers 25 billion CFU per dose from 11 complementary host-specific probiotic strains, including beneficial bacteria and yeast. The formulation combines microbial diversity with a high viable count to maximise the opportunity for beneficial microbes to establish within the gut. This multi-strain approach is designed to support digestive function, microbiome balance and resilience in young livestock during periods when the gastrointestinal ecosystem is most vulnerable.

Yes. Research has consistently shown probiotics provide the greatest benefit when animals experience stress that can disrupt normal gut microflora, such as transport, diet changes, weaning or environmental challenges. By helping maintain a balanced microbial population, probiotics support digestive function, gut integrity and normal immune responses, contributing to healthier, more resilient livestock during challenging periods. This is why 4PRO™ MICROBIAL FORTE also forms the probiotic foundation of BEST START ElectroCALF, where digestive support is particularly important.
