Yes re the follicular wave stuff. Beef cows and heifers are typically 3 wave. A lot of the early work was done in Ireland in beef and it was assumed all cows were 3 wave.

Equally I suspect you've also done very much less with synchronisation. We have some farms that do consistently well, and then suddenly a crap result on a batch. Sometimes obvious why, but sometimes not.

I've heard some people say about the occasional bad result pop up. I haven't had it yet. I started off with 10% conception on my first ever sync 8 or so years ago. I made plenty of mistakes then but have made overall steady progress since . I haven't had a spring or autumn sync under 50% for years.

I think people just get complacent after a while, sloppy on injections or dates and that causes the bad result.

Which program do you follow clay I don't get close to 50% on cows

Which program do you follow clay I don't get close to 50% on cows

And when do you do these programs? Is it only for non cycling cows?

Neither did I at the start. It's not just the program. I've been breeding and culling hard for fertility for 8 years on top of management changes. But with double ovsynch you should get conception rates 5-10% better than natural heats if you do it all right.

All jabs or are you using a prid type device

Difference between a sync program and intervention.

Is it sustainable long term? Pre-synch ovsync is 5 injections. I'm not sure Public would like discovering a cow is loaded with hormones she produces naturally.
How would your herd perform on standing heats now? Vs a herd of cows (that's also been culled hard for fertility) served to standing heats only? Or would the drop be minimal?
My worry would be breeding a herd of cows that only respond to sync programs that "might" be more regulated in the future.

I hope that's the difference I only do non bullers

 

[Clay52]

i don't sync cows because I enjoy it. I sync cows because it works and makes money, more preg cows and less fert culls.

I can get 60% preg on day 1 of breeding despite what some uneducated person claims because they can't achieve that.

I'm getting around 60% on standing heats now and that includes a fair bit of sexed semen usage. Natural heats are not an issue.

If you don't want to use a sync program, don't do it. No one is forcing you to but people can't deny that they do what they are intended to do.

 

[jimmer]

anyone with a half decent block calving herd will expect 40-50% pregnant in first 3 weeks
why ? because they are the most fertile
most of these herds will then look to get another 30% in the next 3 weeks
i would suggest that 50% of the conceptions on second round would have been successful in the first round , if every cow was served to even the slightest heat or whim
so synching them all up properly to serve on day 1 there is no reason not to expect 60+%

the reason clay and many other herds get such good conception rates to full synch programmes is because the best and most fertile cows are entered into the programme , not the problem breeders on round three

The problem is Clay has chosen to remain anonymous so is unable to back up any of his claims and just runs with the old "prove me i'm wrong" stance. I think we can all see the folly in that.

As ever i'm sure there's some truth to the posts but I've yet to see any evidence of a herd of 10000 litre cows all synced up to day 1 achieving 60% conception rates. So i'm choosing not to believe this as it's beyond anything i've heard of before. That doesn't mean i'm right btw!! Just means that rational people don't believe extraordinary claims without extraordinary evidence.

 

[buffalo_soldier]

Ive seen an american paper claiming high sync rates (cant remember how high).
But they were throwing the kitchen sink at the job. Even syncing them up before they went for pd. So not a useful UK comparison.

My syncs are doing around 43% conception this year, to either a conv b/w or fert plus. So ive a way to go yet..
I like finding people who do a better job of it than me, pushes you on a bit.
Just a shame there is so damn many of them.

Haha. Extraordinary claims requiring extraordinary evidence is usually used for people claiming ghosts or things like homeopathy.

Someone achieveing conception rates with a sync program in the ball park of what they have shown to be achievable in research isn't extraordinary.

Don't believe. I don't care.

Oh how foolish of me. Either way I think you see the sentiment of what i'm saying. Tell you what i'll rephrase it then. Unbelievable claims require evidence to become believable.
I am happy to read posts made by anyone and it doesn't matter to me if they don't want to back them up, but it is wrong to shut everyone down by telling them they are uneducated and should disprove you!

Don't believe. I don't care.

Then why did you quote me? What does your caring have to do with it anyway? How old are you for goodness sake.

You have attempted to make others look daft for not providing evidence against you, when really that was for you to do. That's really the only point I had to make here.

 

[In the pit]

When ever you ask @Clay52 to give you evidence to back up his figures he always spouts on about the reasearch he's read. If you've got results then just run through exactly what you're feeding your cows , your calving dates spring/autumn and your fertility figures .your got so much research it should be easy to do

Do a little bit of a google search and you will find getting over 50% is not out of the norm for well done sync programs and this is on US herds averaging 13,000lt.

FFS man you are so aggravating , i am trying to help you out a bit by trying to explain how these figures are achievable , the least you can do as at least give some kind of evidence to back up YOUR results

Yes your line of thinking is if you can't achieve it then it's impossible. That says a lot. Great attitute to have.

oh yes. Someone that keeps popping in and saying I'm a liar really motivates me to go to the effort and bow to your demands for my figures.

That's you helping???

I'm pointing out that those results are not unbelievable or extraordinary.

Last 1100 breedings on my computer say 50% conception. That's including sexed semen usage. I had a dud sexed bull with 0% conception that hurt me.

Ohhh, don't you get your vet to out the semen under a microscope before you start serving? I'm disappointed.
