ctroidl said:Until these show breeders reroute the goal of there operations to produce a variety of genetics centered around a specific phenotype neither industry will make much improvement. I may only be seventeen years old in a business which presents endless learning, but neither linebreeding or inbreeding seem justified and thats why I will never participate in it.
r.n.reed said:Knabe,how did you come to the conclusion that JITs 2 bulls are worthy of building a linebreeding program around?
There are good bulls and females out there that are not linebred, TM Gus 36S, ace of diamonds, many of Grants bulls, homedale creole 135, many of alta cedars bulls, many of the waukaru bulls. Definately trump produces some of the most showy offspring of any shorty sire to have ever existed, and I think his genetics can be utilized in any heard looking to produce great show steers and heifers. There is enough outcross genetics currently available to produce great show animals it just takes longer to develop offspring that can compete.r.n.reed said:Ctroidl,Where do you get this variety of genetics if nobody is out there developing their own distinct line and how do you do that with out linebreeding,Or are you advocating more crossbreeding for the Short horn breed?

I don't know Xbar but this quote right here is craziness to me, The main show bulls being inbred these days include heat wave for clubbies and Trump for shorthorn, from what I have seen these bulls are the farthest out of any from producing consistent offspring. They can be inbred all you want but regardless the results will not be predictable.-XBAR- said:ctroidl said:The bull goes back to Trump and Augusta pride 3127 on the sires and the dams side of the pedigree more than once. When the gametes unite during fertilization and chromosomes cross over, genetic information is supposed to be exchanged in order to produce variety in the offspring. When genetics of the same organism are crossed, the resulting offspring may inherit recessive mutation allels; some may be fatal, but most result in a weeker offspring.-XBAR- said:ctroidl said:Also when choosing a herd bull I like to shy away from having The same genetics more than once in a pedigree,
Your assessment of the bull is spot on but this right here is craziness to me. Please elaborate on your position.
Elevated incidence of recessive genetic diseases
Reduced fertility both in litter size and in sperm viability
Increased congenital defects such as cryptorchidism, heart defects, cleft palates.
Fluctuating assymetry (such as crooked faces, or uneven eye placement and size).
Lower birthweight
Higher neonatal mortality
Slower growth rate
Smaller adult size, and
Loss of immune system function.
I take it you're not familiar w/ selective linebreeding to perpetuate desired qualities and characteristics??? Homozygosity and prepotency are the goals; variety is a bad thing. If you're into show cattle, the best thing this bull calf has going for him is his stabilized, which suggests predictable, genetics.

justintime said:It really doesn't do much good for anyone to develop a line of cattle that are deeply line bred, if no one but yourself is wanting them.
"None but ourselves can free the mind" - Marcus Garvey
We used to have a Hereford herd and we had several females that were intensely line bred to using L1 genetics. At the time, the Line 1 cattle were one of the most intensely line bred Herefords anywhere in the world. I had a set of 16 full sisters from ET that combined a very popular L1 sire and a highly regarded L1 dam. If I had to survive on the calves these cows produced I would have starved to death very quickly. There is no other way to describe them but to say they were just plain bad!!
Holden and Cooper seem to be getting along pretty good w/ them L1's

His Dam is a moderate female obviously and this bull will be absolutely terrific on first calf heifers. Full stop.
