C⁴E3: Processing calves.
Ideal timing for vaccinations in calves is a few weeks before weaning. This offers the best chance for vaccine efficacy. When calves are processed and can go back to their dam (mother), this limits the spike of cortisol from the stress of separation. Cortisol impairs the immune system and its ability to react to vaccine and create antibodies appropriately. Administering vaccine before weaning also gives time for those antibodies to form and become effective before calves are at the highest risk for respiratory disease after weaning.
I typically administer a dewormer for GI parasites and topical pesticide for flies, lice, and ticks at this time.
Ideally, bull calves are castrated around 1 month of age or sooner, but these were done at this time, too. The younger calves are castrated, the easier it is on them for recovery and the less risk there is for blood loss and other complications.
The last calf shown is getting its horns tipped. I use a lidocaine nerve block and typically administer an anti-inflammatory when dehorning or tipping horns for pain management.
C⁴E2: Reproductive Tract Scoring (RTS) and measuring pelvic areas of yearling heifers. This is done pre-breeding along with vaccinations +/- internal and external parasite control. These measurements help cull animals that are not suited for breeding at a time when they are most valuable to sell or divert into finishing for beef. Removing heifers that do not meet the minimum pelvic area from the breeding herd greatly reduces the chances of dystocia (difficulty calving) and emergency veterinary visits to pull calves. Preventative care is incredibly valuable!
Note: This footage was taken in the fall (pre-breeding) for a fall-calving herd, but is still relevant in the spring as this is the time for measuring heifers in spring-calving herds.
C⁴E1: Trying something new with this. Feeling a little cringy and vulnerable putting this together, but I have to admit that I thoroughly enjoyed bringing my creativity to work. It forced me into seeing the beauty of simple moments throughout the day, which was unexpected but really inspiring.
A few things for clarification:
*The first animal in the chute was a heifer that I pelvic examined for a Reproductive Tract Score and measured pelvic area (blue tool in my hand). These values help determine if a heifer is mature enough to breed and reduces the risk of dystocia (calving difficulty).
*The second animal in the chute was examined by transrectal ultrasound for pregnancy (white wand).
*I normally move through animals at a pretty quick pace for both of these types of exams - especially with large groups of cattle. We were taking our time this day because it was a small group and it's challenging and time consuming just getting horned cattle through an alleyway and chute.
Karen back here asking to speak to the manager because she had to wait in line >30 seconds for her ultrasound appointment.
