Dr. Les Anderson, Beef Extension Specialist, University of Kentucky

One of the most challenging aspects of spring calving is trying to determine when to calve to maximize reproductive rate. Reproductive efficiency in a cow herd is most accurately measured by the term “percent calf crop weaned” which is calculated by dividing the number of calves weaned by the number of cows that were in the cow herd when the breeding season began the previous year. The two factors that affect the ability of a cow to wean a calf is pregnancy rate and calf death loss.

Most spring-calving herds begin calving sometime in February or March and end sometime in May or June. Calving in February and March can be challenging because Continue reading

Spotted Knapweed, Ohio’s New Pasture Invader

Keenan tells me that Continue reading
