- Minimizing the risk of trich
As the cows move because of drought, the risk of trichomoniasis (trich) is showing up in new areas.
Minimizing the risk of trich
Trichomoniasis is getting more recognition by states, and more regulations are being developed to try and minimize the disease risk. Because this is a disease that goes with cattle movement, several states are monitoring the bulls that cross their borders. “Most states where trich has been diagnosed have importation regulations now,” Dr. Devin says. “They require testing for bulls moving into the states.”
There are no testing regulations for females, but Dr. Devin advises producers buying cows, especially bred cows, to know the herd status. And, if possible, buy cows that are more than 120 days along in gestation.
“Most abortions or lost pregnancies from trich occur around 90 days of gestation,” Dr. Devin says. “So, if you purchase cows at less than 120 days of gestation, they could be infected with trich, lose that pregnancy and expose your herd through exposure to a bull.”
Putting a trich prevention and control protocol in place is imperative to stop the spread of this disease. If trich is found in your area, Dr. Devin recommends watching your cow herd closely for cows that should have been bred returning to estrus. Check your fences to make sure they are secure and that neighboring bulls aren’t visiting your cows. Preg-check your cows, monitor pregnancy rates and test your bulls for trich.
“Maintain surveillance for trich in your herd by testing bulls at the end of breeding season,” Dr. Devin says. “Stay in contact with your herd veterinarian and your neighbors to keep informed of any trich in your ‘neighborhood’.”
Importance of vaccination
If your cow herd is facing the threat of trich, if the disease has been found in your area, or if there is an influx of cows from outside herds, Dr. Devin strongly recommends vaccination. But, he cautions that a vaccine like TrichGuard® must be used according to label directions to be most effective.
“The first dose of the vaccination should be given seven to eight weeks prebreeding, and the second dose three to four weeks later, followed by breeding four weeks after the second vaccination,” Dr. Devin says. “It is very important to get that vaccination in pre-breeding, especially in an infected herd situation.”
