Spring Calving Herds

Fall calving herds

Treat for grubs now. November 1 is the cut off date for treating cattle for grubs. After that date, grubs may have migrated to areas around the spinal cord and esophagus. If grubs are killed after they have moved to that location, they can cause a severe inflammatory reaction resulting in paralysis or suffocation of the cow. Grubs cause damage to the hide as they cut breathing hole in the skin of cattle. In addition, they reduce animal performance. Many types of pour-ons are available to treat grubs. They include organophosphates like Warbex, Spot-on or Tiguvon as well as the new endecticides like Ivomec Pour-On, Dectomax or Cydectin.

Pregnancy Check Cows at Weaning. Open cows should not be carried through the winter especially this winter with the short feed supply. Cows should be palpated by a veterinarian at weaning to determine pregnancy status. In addition, a good veterinarian can "age the fetus" to give producers expected calving dates for cows. Pregnancy checking costs only a few dollars per cow especially if it is combined with other management practices. Keeping any cow costs an average of $300 per year in Virginia. So if you keep an open cow your are giving away $300 without getting any return.
