Explore our program for supporting intestinal health in ruminants and helping limit dysbiosis.
Ruminants are facing numerous transition periods and stresses that can affect their health status and performance throughout their lives. Supporting intestinal health in ruminants by helping to limit the risk of dysbiosis can help ruminants to be more resilient to stressors and reach higher performance.
Our solutions to help maintain intestinal health in ruminants, from calf growth to calving transition (cows) and receiving (beef).
Lallemand Animal Nutrition has developed a specific approach based on nutrition with documented results to help reduce the risk of lower gut dysbiosis and its consequences at different stages of the ruminant lifecycle.
The objectives are:
- Support early life gut immunity by maintaining gut/intestinal health, which helps reduce the risk of diarrhea caused by enteropathogens (rotavirus, salmonella, etc.) in preweaned calves and repercussions later in life (morbidity, malabsorption, etc.).
- Help limit susceptibility to inflammation and reduce the probability of developing gut system and distal organ disorders (bovine respiratory disease (BRD), bovine viral diarrhea, liver disease, etc.), promoted by gut dysbiosis.
- Support transition dairy cows by maintaining optimal intestinal permeability, to help limit the leaky gut syndrome and its impact on systemic inflammation.

Why choose Lallemand program?
As a global leader in yeast and bacteria production, Lallemand Animal Nutrition has developed a multi-solution approach based on nutrition to help address the challenges of the lower gut health for calves, beef cattle and (transition) dairy cows.
How selected probiotics can optimize microbial balance in the intestinal tract and prevent dysbiosis ?
- Support microbiota balance by promoting positive microbiota composition
- Support improvment in epithelium gut integrity with reinforced tight junctions and mucus production
- Contribute to natural defenses and immunity by supporting an appropriate immune response
