Isn't that shot next Friday PG instead of GNrH? With the second GNrH shot at the time of insemination.
If the plastic string/tail is pointing up, it will poke and irritate the underside of the cow's tail. I trim them since they are so long.
Yes it is thank you for the correction. Don't want to confuse anyone
We use clean up bulls and typically turn them in 10 days after insemination. We do DNA all of our registered stock as well. All the heifers will be preg checked and the vet we use is very effective at determining AI or "bull bred". With turning the bulls in 10 days later is also fairly easy to determine by the birth dates of the calves. If they don't take to AI they typically for us get bred natural service on their second cycle Hence 21 days or so later birth of calves. And yes chlorhexidine solution in the buckets.
The guessing game is in between those dates. Say a calf is born AI date + 293 days. 10 days late or 11 days early? They can be up to 2 weeks early or 2 weeks late. Heat cycles maybe 18 days to 24 days, so that adds to the uncertainty. Then you can decide that maybe the calf is a little small, so it must be early to the cleanup bull. But, is it?
Or is it just because that cow tends to have small calves no matter which bull it's bred to? (reference to one of you other threads)
Ken i don't use any lubricant just the chlorhexidine and I do not force anything a lot of the times a simple slight back and forth rotation does the trick. Thank you for the positive comments on the photos. I know I leave some things out and still learn more each year (which is key we never stop learning and looking to improve) but I do hope these photos help those that are curious about the process
That is true simme but with the the assumption that if bred on x date especially with the hormones in overdrive thanks to CIDRs and drugs then if they don't take on that cycle then the 10 day wait til the bulls are turned in they aren't in that standing heat until their next cycle. Hence pretty accurate by going by birth date. Yes we do we tend to have calves hitting the ground earlier than their due date. We usually observe this and have no doubt who the sire is. The preg check and DNA usually confirms our observations
Yes it is amazing when you think you have things down pat how you can pick up little snippets that help the process. I find youtube videos usefull and like to watch a few leading up to doing my breeding and even ones I have seen before I often pick up something small that might be helpfull. Lets face it most of us are only doing this for a few weeks in every year so you inevitably get a bit rusty between drinks.
