Heartland International, Inc. has been distributing the FASTRACK® line of livestock direct fed microbials since the first were introduced in 1986. Since then, the line of products have been expanded to 19 specific products designed for beef, dairy, swine, poultry, equine, canine, and feline applications.

Fastrack® has gained industry recognition for its comprehensive program of species-specific products.

More than 30 years ago, visionary Conklin researcher Dr. Eugene Stearns developed the first animal probiotic to support the health and performance of food-producing animals. His innovative formula of beneficial bacteria, yeast culture and enzymes helped milk, meat and poultry production when fed – and became Conklin’s signature product, FASTRACK® Microbial Pack.

FASTRACK® has gained industry recognition for continuous formulation improvement, which formed the basis of our comprehensive program of species-specific FASTRACK® products covering an animal’s entire life cycle.

A progressive array of gels, boluses, microbial packs and supplements now make up a line of products for the newborn through senior years that supports:

  • Immune response to pathogen challenge and stress

  • General health maintenance

  • Production

  • Performance

  • Digestion

  • Reproductive and physiological needs of all animals

JD Bartles on FASTRACK® for Beef Cattle and Feedlot Receiving Programs. The integration of the FASTRACK® Direct Fed Microbials as a part of their receiving program have been showing a significant improvement in how cattle take to the feedbunk. The program is simple using the FASTRACK® Ruminant Gel at receiving and using the FASTRACK® Microbial Pack in the feed they first receive.
