If prepotency was important, surely it would have an EPD!!!

Can't sell the same thing more than a year or two so prepotency would hut more than help. So this EDP would be as dreaded as the $E to see if the cattle can (or cannot) be afforded in the feed bill. Change, change, change to sell more, different, better up until the dispersal.

Dead Bull Boogie

I used a “great” bull many years ago
Seems he had been raised by Mr. So-in-So
His calves might have been better, maybe they were fine
Right now the details seem to slip my mind

Chorus:
Oh-h-h, Dead Bull Boogie
Dead Bull Boogie-e-e
Does age help a dead bull
or just dull my memory-y-y-y?

Some said his sons were built just right
I remember a few daughters that created great fright
Athletic, Yea-a-a, I can remember like today
As they cleared the corral panel and sailed away

Oh-h-h, Dead Bull Boogie
Dead Bull Boogie-e-e
Does death change a dead bull
or just trick my memory-y-y-y?

The mailman just brought me a dispersal catalog
They’re selling the cows, the tractor and even the dog
Health and business have taken their toll
After only 7 years it all has to roll

Oh-h-h, Cow Sale Boogie
Cow Sale Boogie-e-e
Does age change a dead bull
or just trick my memory-y-y-y?

On page 37, much to my delight
The old dead bull’s semen offer came into sight
Should I buy it and see if genetic law trumps time?
Maybe this time the calves will be sublime.

Oh-h-h, Dead Bull Boogie
Dead Bull Boogie-e-e
Does age help a dead bull
or just dull my memory-y-y-y?

I`ve never experienced any that I would make any concerted effort to resurrect ...there were probably more contrived, hocus pocus promotional contests in the early years of performance testing than the epd game represents now...

Familiarity breeds contempt is a saying that comes to my mind when people grab a bit of this and a bit of that to add a bit of this and a bit of that.

Will inbreeding ruin a population?  Will the closed population lose diversity?

lines, bulls, or just bs ?


Here is the first bull I'm gonna share that sells on 2-27-17 in our production sale. He is a Sitz Lightning x HA Program x Final Answer x 878 x E551 (Dam of Volunteer and Exceed). From what we do here all of these lines have worked excellent and these lines have most importantly done great things for our commercial customers. His maternal sister by Thunder serves as a promising donor and his highly productive dam sells in February. The bull himself is sound, fluid and full of producing cattle with staying ability and performance.

fetal programming?
Fetal programming can only work with what is available in the DNA for a particular conception. Differences would be genes that were turned off, genetic noise, mutation, recessive genes being concentrated and exhibited or genetic loss. All I can say - there must have been some good and tough genes in the original two.

We have hashed and rehashed: Line 1 Herefords are left of 14 lines. There used to be a few others from another line, maybe Line 7. Pretty poor odds of success in linebreeding - down around 15% or less for this example of the Hereford lines. Talked to a linebreeder not on this site and he had about the same % success at 15%. It would be interesting to know how many sources and trials Larry went through before he opted to go with what he did for Tru-line. I have no idea but the point is that the actual % is not important but to know that it took a few of many to build the base.

Have you ever wondered, water under the bridge, of course, if Lingle had taken the 15 to 20 imported bulls (might be more or less - just throwing out a number) and selected for fertility and function rather than growth in Francis the outlier - How many "great" and "foundation" bulls would still be used in that herd today either by semen of the original bull(s) or bulls bred there which "carry" the bloodlines. Funny to talk with folks who have studied the herd and ___, ____ and ____ were the greatest based on daughters but the influence got mixed with a dozen more bulls that did not make the top 3 and still does today.

What if the 15% success/85% failure is even close? What if Wye only had cattle left descending from 2 or 3 or 4 or 6 great bulls instead of all in a rolling of generations fashion. How would things be different? Who knows? We get what we breed for, or do we?
