A new publication from the South Dakota Cooperative Extension Service can help beef producers get more calves. Extension Extra 2068, “Increasing your calf crop by management, pregnancy testing, and breeding soundness examination of bulls,” is available online at a South Dakota State University Web site, http://agbiopubs.sdstate.edu/articles/ExEx2068.pdf. Or ask for it at your county Extension office. SDSU Extension Beef Reproduction Management Specialist George Perry, Extension Veterinarian Russ Daly, and Marshall County Extension Livestock Educator Tyler Melroe wrote the publication. It discusses the importance of a high-percent calf crop, possible causes of a reduced calf crop, and ways to increase calf crop by nutrition and by managing herd health. The publication discusses both diseases that affect reproductive performance of the cows, and diseases that cause calf loss from birth to weaning. The authors also deal briefly with breeding and calving seasons; calving distribution; dystocia, or difficulty with calving; and record keeping. They discuss what is involved in a breeding soundness exam and in pregnancy testing. Consult the publication for more details.
