Description
Tri-Start Jr.+ Paste is a direct-fed microbial (DFM) and immune support supplement designed to jump-start a calf’s digestive system when performance is compromised. Whether calves are facing environmental stress, management changes, or health challenges, Tri-Start Jr.+ delivers a powerful combination of technologies to restore balance in the gut.
Each dose contains 20 billion CFU of live, naturally occurring microorganisms, including lactic acid bacteria, yeast, and fungal extracts. These microbes help establish a beneficial microbial population in the rumen and intestinal tract, improving digestion and creating an environment that limits pathogen growth.
The inclusion of egg antibodies (IgY) and mannan-oligosaccharides (MOS) helps bind and remove harmful pathogens, while vitamins C, E, and B with selenium yeast provide critical immune and metabolic support, especially important in young calves that cannot yet produce sufficient B vitamins on their own.
A key differentiator is the coated short-chain fatty acid, which bypasses the rumen to reach the lower gastrointestinal tract. This supports gut lining integrity, improves nutrient absorption, and helps prevent pathogen attachment.
Tri-Start Jr.+ is designed for targeted use during high-stress or high-risk periods, including:
- Following colostrum feeding
- At weaning
- After antibiotic treatment
- During digestive upset or scours
- After use of Tri-Purify
- During management stress:
- Dehorning
- Castration
- Transport or shipping
- Vaccination
- Pen moves or grouping changes
Using a calf probiotic paste during these events helps maintain performance and reduces setbacks in growth and health.
