Hey just a few things to get out there.
1) Starting December 1st the FCC rules on sending and receiving text messages are changing for some carriers. I use Grasshopper for my business line, so there will be some changes that happen. I am not sure yet if I won't be able to receive texts, send texts, or potentially both. I receive a lot of texts, as many of you it seems like that is your preferred way of communication, this may affect you. Remember, calling is always better as you will get my voicemail giving you information on my availability (I change it if I am on vacation or know I will be out of the area). I should know more on what will change in the coming weeks, but please be aware of the possible change.
2) For my beef clients out there, I came across a "newish" breeding synchronization with one shot of PGF2a (such as Lutalyse and Estrumate) for bull breeding herds that has some more research now. This comes out of the University of Nebraska and showed 75% of cows calved in the first 21 days of the calving season using the following protocol as compared to 63% of cows from a non-synchronized herd. Using this protocol it is VERY IMPORTANT to make sure that bulls have a proper BSE (Breeding Soundness Exam) prior to the breeding season, and they also recommend a bull-to-cow ratio of no more than 1:15 for yearling bulls and 1:25 for mature bulls. This also requires you to actually have a calving season. If the bull lives with the herd all the time, don't touch this!
Day 0: Turn in Bulls
Day 5: Give ALL Cows PGF2a
Day 6-10: Synchronized Breeding occurs
Day 10+: Normal Breeding Coverage continues until bulls are removed
The injection of PGF2a causes any cow with a MATURE CL on the o***y to regress, which causes progesterone production to stop, causing cows to come into estrus (heat) usually within 3-5 days.
But doc won't the shot of Lute cause them to abort if they get pregnant before I give the Lute shot!?!?
Nope, if the cow and bull have a little "rendezvous" between Day 0 and Day 5 the CL will not be MATURE enough and will not respond to the PGF2a injection. This is the same reason I tell you all to wait a week after pulling bulls out if there are accidental "rendezvous" involving fence jumping/smashings or heifer calves living with bull calves too long.
Like any synchronization protocol you have to be on point with timing! Don't push you PGF2a injections out any further than Day 5 for this one. This is also just a tool in the toolbox to potentially get more calves in a tighter window. Please remember that to first be successful with any breeding operation, animals need to have proper nutrition, body condition scores, health, and you have to have enough bulls that have had a BSE to get the job done!
