ET calf I’m hoping...

Postby NEFarmwife » Thu Sep 20, 2018 6:34 pm

I had posted this spring about an overdue ET calf. She ended up calving 20 days past her calving due date which my husband says is unreal. But based off her heat and when we turned in the bull, she has to be an ET. Husband says no way. We worked calves today and she’s so nice. She also weighed at 700lbs. Her adjusted is 676.

She’d be a SAV Revolution/Emblynette daughter. Either way, she’s a nice looking heifer.

But listen, I have a BIG bet going so I need prayers. Ha!

In other news, all our calves today acted like they either ate a lot of turkey or got ahold of some wacky weed. They all worked thru the chute flawlessly and while we pride ourselves on docile cattle... this was almost eery. They had just enough “go” to get worked.

$37 will tell you all you need to know...get the DNA cards and you will know for sure. Make a bet with your husband first.

I wouldn’t wager too much on it. Odds are probably less than 5 percent.
How long did you wait to turn in the bull?
We had a few calves that we thought might be ET that were 9 and 13 days late. Both were early calves by the Cleanup Bull.

Collected the samples today as we worked everything.

Her heat would have been April 6th. 2nd heat “should have been April 27th but didn’t turn bull in till May 1st. Which still would have made the calf a possible natural service.

We have a lot of good females but she looks exceptional. You put her next to her contemporaries and she sparkles. For the cost, I couldn’t wonder. I have to know!

My money is on the cleanup bull, but I hope I am wwwwwwrong.

Me too! Odds are against me. I told myself if she was an ugly calf, I wouldn’t even bother.

I’ll keep everyone posted. Hoping for a win!

Yeah, I’d bet the ranch on the cleanup bull. But it sounds like the recip must be a pretty good cow.
About 70 percent of our cows seem to calve
Before the 283 day due date. But hopefully I am wrong.

I have been keeping track of length of Gestation for the last few years. I write down the date any time I see a cow bred natural and the AI ones are obvious. My gestation calculation on 177 Angus cows was just under 280 days. 60 AI sired calves had an average gestation of 278 days while 117 bull bred cows averaged 281 days. This year I had 13 AI sired calves born. They were born 268 to 283 days from the AI date. The 268 day calf was born to a heifer. With the exception of one cow whose calf was born on day 283, all others were 280 days or less. Angus claims an average gestation pf 281 days.

I am betting on the cleanup bull also. Your $37 will get you a full genetic profile. If you only want parentage, that is just $18. I would go for the full profile, because of all the additional information you will get.

Ended up doing the full profile. Either way, recips does wean off some good calves. She’s had two “commercial” bulls that have made our bull sale. We usually sell 13-15 commercial bulls a year for a good $ average.

I’m pretty sure that according to American Angus Association that they still base it on 283 days. But, like your experience and mine, it seems to be sooner than 283 average.
I think a lot of it depends on the BW of Sire and Dam.

Average gestation varies by breed and I took the 281 day average for Angus from several different studies. I think the link you provided is one AAA took from another site. It uses the average for most British breeds, which is close enough for most calculations. Many Angus bulls are bred to other breeds, so it makes sense that the calculator they provided would be based on 283.
Here is a quote from Ron Torell, Extension livestock specialist University of Nevada that was printed in an article in the Angus Bulletin.

"The gestation length for all breeds of cattle averaged together is 283 days. The range is 279 for Jersey to 292 for Brahman. On the average, the Continental breeds of Charolais, Simmental and Limousin exhibit gestation lengths of 289 days. English-bred cattle such as Angus, Shorthorn and Hereford exhibit, on the average, shorter gestation lengths of 281, 282 and 285 days, respectively. Within those breeds the average gestation length can vary an additional 12 days on either side of the average for the breed."

Yeah it probably should be less than 283. But that is what the American Angus Association uses. I think with all the CE x CE breeding that is pushed so hard the average would now be less than 280?

Sounds like you have the cows job backwards. She has proven she can produce good calves no matter how she's bred. Guess your breeding more for numbers instead of what the animal looks like?

No, she was used as a recip because she is a good mom and came into heat at the right time for ET transfer. When you have someone come to your farm to mass ET (30+) and do a flush, you are at the mercy of which were in heat a week prior. Then choosing which of those are good mothers who may take to the ET better based on their AI'ing or bull bred history.
