On this episode of Cattle Chat, the team discusses how Theileria, a tick-borne parasite that destroys red blood cells, requires laboratory testing for confirmation and cannot be diagnosed reliably from visual signs alone. They emphasized that positive test results must be interpreted alongside clinical signs and herd history, since infection does not always mean it was the direct cause of illness or death. The group also explored how larger cows may produce heavier calves but require greater nutritional inputs, making optimal cow size dependent on forage resources and overall production costs. In addition, they highlighted that successful rebreeding of first-calf heifers depends on early calving, proper nutrition, and consistent mineral intake to support recovery and fertility.
