T-Snip™: Genetic Test for Fescue Tolerance

What is T-Snip™?

T-Snip™ is a genetic test that uses an animal’s DNA to describe its tolerance to toxic fescue. DNA from hair, blood, or semen is analyzed based on multiple genetic markers. The DNA results are converted to a T-Snip™ Tolerance Index, which is used to calculate a T-Snip™ Star Rating. Cattle that score 0 to 1 stars are most susceptible to fescue toxicosis; cattle that score 4 to 5 stars are most tolerant to fescue toxicosis.
