With recent temperatures peaking around 105°, we left the house with headlights early yesterday to Bangs vaccinate 99 head of this year’s heifer calves after making the sort last week. While we waited for yesterday’s 7:00 a.m. appointment with our veterinarian, we decided to keep them on the irrigated pasture close to the corrals, knowing we risked a mix-up with their older sisters, separated only by a barbed wire fence. Something spooked the 99 in a corner under the shade of the Valley Oak on Saturday and they laid the fence down. So we had two bunches to gather and sort before the vet showed.
The vaccination named for Danish veterinarian Bernhard Bangs is to protect against Brucellosis that also infects Bison and Elk, where the greatest concentration of the disease is in the Yellowstone area. Furthermore, female cattle cannot be shipped out of California without proof of a Bangs vaccination that includes a tattoo and metal ear tag that needs to be administered by a vet before the calf is a year old.
But it went smoothly. Bob had most of the 99 baited into the corrals before we arrived and was working on the second bunch of 50 bred heifers as the girls unloaded their horses. Our heifers are gentle. The sort and processing were trouble free—a booster round of calf vaccinations plus the Bangs, injectable wormer and mineral supplement. All done by 8:30 a.m. without hurrying—a great day!
Aiming to keep 50 replacement heifers from the 99, we will make another sort in 4-6 weeks.
