Saturday we bangs vaccinated about 80 head of heifers. Brucellosis is a disease that use to be very prevelent in the US. It causes cows to abort or go into preterm labor. Due to an industry wide attempt Brucellosis has been nearly wiped out of most of the US. In 2007 the US had almost eradicated the disease from the US cow herd with only 0.0001% of the cows being infected with Brucellosis. The problem with 100% eradication is that wildlife such as bison and elk can transmit the disease to cattle. According to the USDA the elk and bison living in the Greater Yellowstone Area are the last know focus of brucellosis eradiction, however the management of wildlife causes great challenges of complete elimination and increases the chance of brucellosis occuring in the US cow herd. Breeding cattle shipped between states have to be bangs vaccinated prior to shipment. Heifers must be vaccinated prior to their 1st birthday.

Aout of the 80 heifers we bangs vaccinated part of them are the keeping heifers for ourselves, part we are selling, and the remainder belong to the neighbor that we have been taking care of since November. One of these days soon those heifers will be sold and our pens will be emptied out just in time for calving. Even though we don't calve in the pens we do use some of them to water the cows, they have automatic water tanks with heaters so no ice to chop (unless a heater breaks).
