Why gut health determines modern livestock performance?
In modern animal production, intestinal health is the foundation of profitability. The gut is responsible for converting feed into high‑quality meat, milk, and eggs, and it plays a central role in both performance and welfare outcomes. A healthy intestinal system is the foundation of efficient animal production. When the gut is compromised, animals experience:
-
- reduced nutrient utilization
- lower growth and performance
- higher susceptibility to enteric pathogens
- and a increased likelihood of therapeutic intervention
As antimicrobial stewardship becomes a global priority, the most sustainable strategy is to proactively strengthen intestinal resilience.
How InteStim strengthens the gut ecosystem?
Did you know, InteStim is built around four essential pillars of intestinal resilience that veterinarians and nutritionists monitor:A robust intestinal wall
Supports the intestinal barrier and epithelial integrity
A balanced microbial ecosystem
Helps balance the microbiome and reduce pathogen pressure
Strong immunity shield
Supports immune competence to improve resilience under challenge
Efficient digestion and absorption
Supports digestion and gut motility to optimize nutrient utilization
Phytoactives and postbiotics: a dual approach to modulating the intestinal microbiota
InteStim supports gut resilience, regardless of timing or pathogen type
Enteric pressure is rarely “one pathogen, one moment,” and it can differ by production stage. Enteric challenges vary widely between poultry, pigs, and calves, and can shift rapidly with diet, environment, and pathogen load.
InteStim is designed to deliver broad, consistent gut protection before, during, and after challenge, regardless of timing or etiology. This dual approach, a combination of phytoactives and postbiotics, provides a holistic approach to gut health, delivering sustainable protection that works in harmony with the animal’s natural physiological systems.
Furthermore, phytoactives and postbiotics have emerged as a natural alternative to antibiotic growth promoters in production animals, contributing to more efficient digestion, increased weight gain, and improved feed conversion rates without the side effects associated with antibiotic use.
Phytoactives
The phytoactives (plant-derived compounds) in InteStim contribute to a more stable and resilient gut ecosystem by supporting:
- Epithelial integrity
- Anti-parasitic activity (e.g. coccidiosis)
- Anti-bacterial activity
- Anti-spasmodic activity
- Immunomodulatory effects
- Natural defense mechanisms
Postbiotics
A postbiotic is a preparation of inanimate micro-organisms and/or their components that confers health benefits on the livestock. Postbiotics in InteStim deliver targeted biological activity without the variability associated with live microbial products:
- Pathogen exclusion & antimicrobial activity
- Microbiome balance
- Nutritional support
- Immunomodulatory effects

Frequently Asked Questions
-
What makes InteStim different from standard gut health additives?
InteStim stands out because it is a unique combination of phytogenics with postbiotics in a synergistic, scientifically backed concept that delivers broad intestinal protection across pathogen types and animal species, while optimizing gut function and integrity.
-
Can InteStim be used in pelleted feeds? And is it resistant to high temperatures?
Yes, InteStim is thermostable. All ingredients withstand high temperatures, ensuring optimal concentrations of active ingredients after the pelleting process.
-
Can InteStim support AGP‑free production?
Yes. InteStim provides a non-antibiotic pathway to manage pathogen pressure by using phytoactives to disrupt bacterial membranes and postbiotics to bolster the intestinal microbiome. InteStim is specifically formulated for AGP-free (Antibiotic Growth Promoter) environments. It addresses the “performance gap” often seen when AGPs are removed by providing alternative mechanisms for pathogen control and anti-inflammatory support.
-
Is InteStim suitable for young animals?
Absolutely. Young animals often see the greatest ROI because their gastrointestinal tracts are sterile at birth and highly plastic. InteStim supports the “Microbial Programming” phase by helping beneficial pioneer colonizers establish themselves before pathogens can. InteStim also promotes intestinal morphology and immune development. This early intervention “primes” the gut for lifelong resilience.
-
Why is gut health critical for performance in farm animals?
The gut is the largest immune organ in the body. Up to 70% of the immune system is located in the Gut-Associated Lymphoid Tissue (GALT). Poor gut health leads to “nutrient hijacking,” where the animal consumes protein and energy to fight subclinical inflammation rather than for growth. Furthermore, a compromised gut barrier allows endotoxins (LPS) to enter the bloodstream, triggering a systemic inflammatory response that severely depresses appetite and weight gain.
Strengthening intestinal resilience is therefore a key strategy for:
– improving feed efficiency
– reducing disease pressure
– supporting sustainable production -
Which farm animals can benefit from InteStim?
InteStim is a multi-species solution designed for monogastric animals (poultry and swine) and pre-ruminants (calves). It is particularly effective during high-stress physiological windows, such as weaning in piglets, the starter phase in broilers, and the transition to solid feed in calves, where the enteric nervous system and microbiome are most vulnerable.
-
Can InteStim replace antibiotics?
InteStim serves as a cornerstone in Antibiotic-Free (ABF) and Raised Without Antibiotics (RWA) programs. While it is not a direct “drop-in” pharmaceutical replacement for treating clinical infections, it functions as a prophylactic strategy. By balancing the intestinal microbiome, it prevents the dysbiosis that typically necessitates antibiotic intervention.
-
When to use InteStim?
InteStim is particularly effective in periods of intestinal stress:
- Poultry
– Coccidiosis pressure
– Heat stress
– Feed transitions
– Performance variability - Swine
– Weaning stress
– Post‑weaning diarrhea
– Neonatal diarrhea
– Dysbiosis challenges
– High pathogen pressure - Calves
– Early-life digestive instability
– Scours risk
– Stress from grouping or transport
- Poultry
-
Does InteStim improve performance indicators?
Yes. InteStim is engineered to optimize Feed Conversion Ratio (FCR) and Average Daily Gain (ADG). By supporting gut integrity and microbiome balance, nutrient digestibility, and by reducing pathogen pressure and inflammation, InteStim helps animals absorb nutrients more efficiently, which translates into better growth performance and improved FCR (especially under gut-challenge conditions).
-
How to reduce enteric issues in broilers?
Preventing enteric issues in poultry requires a holistic approach, involving nutrition and management strategies:
– Start with biosecurity + litter/water hygiene: keep houses dry, manage wet litter fast, maintain drinking lines clean, and enforce strict cleaning and downtime between flocks.
– Optimize nutrition and gut function: use highly digestible raw materials, control anti-nutritional factors, balance amino acids, manage fat quality, and avoid abrupt feed changes.
– Support a stable microbiome: apply targeted gut-support additives (for example postbiotics, phytogenics, organic acids, and selected enzymes) based on the main challenge and age phase.
– Reduce pathogen pressure: vaccination where relevant, robust coccidiosis control, and early detection with routine monitoring (droppings, litter score, uniformity, mortality, lesion checks).
– Lower stress and immune suppression: maintain ventilation and temperature, prevent heat stress, avoid overcrowding, and ensure consistent access to feed and water. -
How to support calf gut development?
Calf gut development is a race against time between birth and weaning. Support should focus on both anatomical growth and microbial colonization:
– Colostrum and transition milk first: deliver enough high-quality colostrum quickly, then use transition milk to drive early gut maturation and local immunity.
– Feed promoting rumen and intestinal development: consistent milk/milk replacer program, offer clean water from day 1, and introduce a palatable starter early to stimulate rumen papillae and gut enzyme activity.
– Protect the gut from pathogen entry: excellent hygiene for feeding equipment and housing, reduce exposure pressure, and use evidence-based scours prevention (including vaccination and monitoring where relevant).
– Support the intestinal microbiome and barrier function: consider targeted supplements in milk or feed (for example postbiotics, organic acids, and selected phytogenics) especially around stress moments.
– Minimize stress and inflammation: keep calves warm and dry, avoid overcrowding, manage weaning gradually, and maintain stable routines to prevent setbacks in intake and gut integrity.
-
Can InteStim be used for neonatal and post‑weaning diarrhea in piglets?
Yes. InteStim can be used both in neonatal and post‑weaning phases to support gut integrity and intestinal microbial balance, helping animals stay more resilient to diarrhea risk, especially during those high-stress transitions,while it should be used as part of a broader hygiene, nutrition, and health program.
-
What improves microbiota balance in livestock?
Microbiota balance, or eubiosis, is improved by stabilizing the gastrointestinal environment through a multi-factorial approach:
– Stable, well-balanced diets: consistent feeding times, adequate fiber structure, and avoiding sudden ration changes help prevent dysbiosis.
– High feed and water hygiene: limit mycotoxins, rancid fats, and microbial contamination, and keep water quality and drinker lines clean.
– Support fermentation and gut barrier function: use targeted tools like biotics, organic acids, and enzymes when they match the species, age, and challenge.
– Reduce disease pressure and inflammation: strong biosecurity, vaccination programs where relevant, and early control of enteric pathogens and parasites.
– Lower stressors: optimize stocking density, temperature, ventilation, transport handling, and weaning transitions, since stress reliably disrupts microbiota stability.
