My herd was diagnosed with trichomonosis: How do I get trich out of my herd and keep it out?
• Test all bulls three times and send all infected bulls to slaughter. • Heed the adage, “good fences make good neighbors” – keep fences in good repair to keep neighboring bulls out of your herd. Commingled grazing or fence–line contact with other herds is a documented risk factor for trichomonosis infection. • Trich test all herd bulls annually prior to breeding, at the time of annual fertility exams. • Maintain a defined breeding season – this will help identify reproductive problems more readily and will produce a more uniform calf crop. • Pregnancy test all cows and heifers after the breeding season and cull open females. • Segregating cows based on gestation length at the time of trichomonosis diagnosis may be considered: • Cows pregnant five or more months have the lowest risk of being infected. • Cows pregnant less than five months should be pastured separately and observed closely. Cull any of these cows that abort. • Open cows with or without pyometras or other uterine abnorma
