As the nation's people have become more mobile, so have the nation's cattle herds. Shipping cattle across state lines is a regular practice, particularly in times of short pastures.
This movement, while creating new economic opportunities for some producers, has created unintended consequences in increased animal disease outbreaks. One disease that has seen an uptick in recent years is trichomoniasis.
Trichomoniasis, commonly referred to as trich, is a venereal disease of cattle caused by the protozoan parasite Trichomonas foetus. Spread through breeding, trich causes infertility, abortions and, occasionally, chronic uterine infection in dairy and beef cattle.
