Overview
ProTernative is a lower gut-specific live yeast strain selected to support gastrointestinal health in young ruminants during their most critical growth stages. Authorised for use in calves, other young ruminants, and Camelidae across Great Britain, ProTernative helps maintain the health of young ruminants and improves performance.
What is ProTernative?
ProTernative contains Saccharomyces cerevisiae boulardii CNCM I-1079, a lower gut-specific live yeast strain backed by more than 60 years of efficacy and research documentation related to gastrointestinal health in humans and monogastric animals. ProTernative acts in the lower gastrointestinal tract, which means it can play a vital role in ruminant youngstock where the rumen is not yet fully developed.
Key benefits
- Supports gut health: helps maintain a balanced gut microbiota and associated gut integrity
- Boosts defences: helps youngstock be more resilient in the face of common challenges such as digestive upsets including those linked to weaning stress.
- Enhances performance: increases average daily liveweight gain while helping maintain gut health.
Mode of action
ProTernative is authorised in GB as a gut flora stabiliser and works across three essential pillars of gastrointestinal health:
- Microbiota balance: encourages beneficial microbes
- Gut integrity: helps maintain epithelial integrity
- Natural defences: contributes to maintaining normal immune function
Usage
- Target Animals: Dairy and beef calves from birth to approximately 4 months of age, lambs, goat kids, and young Camelidae
- Application: Inclusion in milk replacer formulations or as part of an on-farm supplement.
Proven results
Global trials show that (compared to non-supplemented animals) calves supplemented with ProTernative demonstrate:
- Improvements in parameters linked to gastrointestinal health
- Greater resilience to stress
- Increased average daily gain
Part of a complete youngstock program
ProTernative is part of Lallemand’s comprehensive youngstock portfolio, designed to help animals grow into healthy, productive livestock that perform throughout their lifetime.
