Product Details

Description

Tri-Start Jr. Bolus is a research-backed direct-fed microbial formulated specifically for dairy, beef and beef-on-dairy calves to support digestive health. Each capsule delivers a guaranteed 20 billion colony forming units (CFU) of live, beneficial microorganisms selected to establish and maintain a healthy microbial balance in the gastrointestinal tract.

This microbial combination works in both the rumen and intestinal tract, helping calves transition through critical stages such as post-colostrum feeding and weaning. By promoting beneficial bacteria and crowding out harmful pathogens, Tri-Start Jr. supports improved gut integrity, enhanced nutrient utilization, and stronger immune response.

The inclusion of live lactic acid-forming bacteria, yeast, and fungal extracts creates an optimal digestive environment that activates naturally occurring microbes already present in the calf. This can result in improved feed intake, better average daily gain, and a reduced likelihood of digestive disturbances like scours.

Tri-Start Jr. Bolus is especially effective during periods of stress, whether management-related (dehorning, castration, shipping, vaccinations) or nutritional (feed changes, antibiotic recovery).

Packaged with advanced moisture-control technology, each bolus maintains guaranteed viability with a 12-month shelf life, ensuring calves receive a consistent and effective dose every time.
