THERE WAS A PLACE WEST OF US THAT HAD COWS DROPPING FROM SOME UNKNOWN REASON. HE HAD THE VET COME OUT AND IT WAS DIAGNOSED AS A STRAIN OF BLACK LEG, BEFORE HE GOT THEM ALL IN AND VACCINATED I THINK HE LOST MORE THAN TWENTY HEAD. THEN LAST YEAR A WEEK BEFORE WE WERE GOING TO VACCINATE HE HAD A BULL AND TWO COWS DROP DEAD SAMETHING. NOW EVERYTHING GETS A SHOT SPRING AND FALL FOR BLACKLEG AND IT IS FOR A CERTAIN STRAIN. ALSO WE WERE GOING OVER TO HELP A NEIGHBOR AND HE HAD A SICK CALF IN BARN FROM NIGHT BEFORE AND IT HAD DROPPED DEAD, AND WHILE WORKING THE CALVES THROUGH TWO MORE DROPPED WERE ABLE TO SAVE THE LAST TWO WITH HIGH DOSES OF PEN. LUCKILY WE WERE VACCINATING THAT DAY AND NOT A DAY LATER. I THINK THEY GAVE ALL THE CALVES PEN. AS WELL JUST TO BE ON THE SAFE SIDE.
