except they really do marble. the other traits, i agree, every breed says.

That does look good...Team White Angus is expanding their horizons. I wonder if Akaushi is the Waygu marbling gene they are going to use. Although I thought the heritability on marbling was more like 0.45?

“If you find a high heritability trait you like in one breed, you can move it into another breed quickly and cheaply,” he said, agreeing this included possibilities such as dropping the highly heritable Wagyu marbling trait (heritability of 0.8) into a breed such as Brahman, without adding other genes."
Edit- wow that's weird. That quote was pure cut and paste-it says heritability of 0.8. It even says that in the text inside the modify box on the post- repasted here:

Does this mean Gremlins are built into "articles" on the Internet or an is there an internal skeptic feature within Steerplanet code that comments on our comments?

This article has inspired me to startup an EPD splicing laboratory. Major investors can send money straight to me at my Nebraska research complex. Already we have the technology to insert entry level exalted marbling EPD's into less EPD adapted breeds thru ( aj, here us where you will want to get on board) the appendix program.

Librarian........I will admit. My herd is almost totally Red Angus-Shorthorn composites........partially because of the marbling deal. My base bull Valiant was a Lancer son that was a 4 star carcass bull from ABS. From my half blood status I could spring board to a seven-eights status in two generations. It would be safe to say I have a few asterisks in my pedigree's. I have cattle that are 4 generations deep in double breeding to the old Valiant bull that bang in there at a 50% percentage level. I'm still kicking around the idea of forming a new breed.

aj, my own personal point of view is that breeds are becoming increasingly irrelevant. It's breeding that is important and learning how to blend breeding together. What was formerly known as the Breed in Breed composition is better described as genetic base- from concentrated bloodlines.

I've been trying to study up on this Lancer bull- but there are many. Like as old as 442?aj said:
Here is a bull, Beckton Nebula, that I would guess was a Shorthorn just on appearance.
I don't understand the usefulness of trying to split out a New Breed. Some Shorthorns are more similar to Red Angus than they are to other Shorthorns. I think your idea is better suited to a Brand of red cattle. At least using Red Angus bulls puts Shorthorns where they excel- as cows. If one believes all the stories, Shorthorn cows contributed significantly to the Red Angus breed anyway.

I would have jumped into the Durham Red deal a little harder. But as I understand it you can have thc, phac, and dsc cattle in the Durham Red program. The Shorthorn breed has such a terrible reputation of tolerating and embracing lethal genetic defects I couldn't let that deal overshadow my program.

Roger that. I just experienced a major disillusionment regarding double muscling, Shorthorns and some genetics. I know stacking pedigrees also stacks recessives. My disappointment is in breeders that don't put the information on the table so their customers can make informed choices...but defects or lack of defects don't define a breed or breeder. Only honesty or DNA can accomplish a reputation for credibility. I think we've reached the point where it the customers don't require genetic testing, their willing ignorance is part of the problem.

Entire post is willing ignorance.
I would suggest reading Strategies for Managing Marbling in Beef Cattle by Harlan Ritchie and a University of Minnesota research paper entitled Holstein Feeding Programs for some useful, factual information. I found the Holstein information particularly interesting.

I think I see what you are getting at. I've been reading about low carbohydrate diets and how some people have metabolisms that speed up in response to excess energy and burn it up while others have metabolisms that do not speed up, and the surplus energy is stored as fat.aj said:
We fatten cattle with a very high carbohydrate diet and the carbs are stored in IMF if the sugar was glucose.
I keep reading that early weaned steers that are put on feed sooner marble better. If we believe this, then isn't marbling easy to manipulate in a feed trial by enrolling animals that were weaned earlier? How would one sort that out from the EPD's and accuracy conclusions about heritability?

i can only give anecdotal evidence on this.
saw a cut sheet on 60 heifers and 60 steers from 8 bulls, 2 of which were from my bulls.
total, there was 5 select, 15 prime, the rest were choice. 3 of the selects were yg1, the majority of the rest were 2,3, i think there were no 4's. these cattle were not from even remotely "good" genetics. they were weaned, placed in a grow yard for 2 months, then went to harris ranch to be fed 120 days. they were all roughly 14 months old. another set of 60 animals were left on grass, never really grew, basically lost months, were docked at the sale and performed poorly in the feedlot and were almost 20 months on average if not older. yes, it cost to put them in the grow yard, i forget what the premiums were, i can get them later. but overall, i was impressed by the quality, the age, and the complete lack of supposedly quality genetics. if these can perform that well, better genetics, along with feed efficiency stacked should make it relatively easy to get premiums. not sure why people are having such a problem at some level. i think librarian is hitting at it around the edges, keep them growing, when they stop growing, gaining, they are probably losing the marbling which is probably easy to lose but hard to get back once lost.

Johnson said one of the keys for U.S. beef producers to increase marbling and oleic acid synthesis in beef is grain feeding or corn feeding and the most detrimental thing that can be done is grass feeding, or grazing.
[/size]"What happens in the rumen when animals consume grass or roughage, their fermentation pattern is such that it reduces marbling even more," Johnson said. "They have fewer amounts of oleic acid for beef. Grain feeding very much promotes marbling deposition. That's one thing we do in feedlots that does promote marbling.
