Greetings from Lone Mountain Cattle Company

March 16, 2017 by LMCC

Hello Everyone!

Here’s hoping that every one of you has been having a great start to the year. Pictured below is a beautiful winter wonderland at the ranch. Mother Nature did not disappoint this winter season.


2017 is shaping up to be an exciting year for Lone Mountain.



We are busy getting ready for our 5th Fullblood WagyuProduction Sale on SaturdayOutstanding MarblingMay 20th at the Beef Barn inside the New Mexico State Fairgrounds in Albuquerque. Mark your calendars. We are confident that this salewill be a great way to start your herd if you are new to the breed – or enhance your current herd. Highlights of the (primarily) Female Sale will include 4 SCD AA Fullblood Wagyu Bulls, including one that is rated AA 10 and 100 Fullblood Wagyu Heifers and Cows, Pairs, Bred and Opens.


Schedule of Events for the Sale:

  • Lone Mountain will host a welcoming reception from 5-7pm MST on Friday evening, May 19th, at the Marriott Hotel in Albuquerque (Sale Headquarters). Wagyu Sliders will be served. A great place to network and get to know your fellow Wagyu breeders.
  • We are in the planning stages of a BREEDPLAN seminar on Friday afternoon at the sale site – stay tuned for further developments.
  • A free lunch on Saturday just prior to the sale. We will be serving Lone Mountain Wagyu Brisket tacos and mouth-watering Lone Mountain FB Wagyu Sausages.
  • The Sale will begin promptly at 1PM – Butch Booker, Auctioneer. Sale management by Jim Danekas Associates (JDA).

We have special room rates booked at Albuquerque Marriot Hotel, 2101 Louisiana Boulevard NE Albuquerque NM  87110. Please use this link to get the best rates.

This is the 5th Lone Mountain Production Sale – all with the same management and auctioneer. This will be the first, however, without Jim Danekas on the podium. Though his daughter Mercedes will competently be with us in his stead.

At the same time as we are putting the finishing touches on the Sale Catalog, we are also polishing up our first LMR Bull Battery Guide – which should at the printer shortly.  We are confident this directory will be very useful for those looking to utilize Lone Mountain FB Wagyu genetics to refine and improve or simply to diversify your herd – whatever your breeding goal: F-1 to Fullblood.

In addition to putting a tremendous amount of work with putting together the sale catalog, we finished photography just last week. Allan Browarny handled the tremendous work of capturing beautiful images of every single animal that will be for sale on May 20th.

LMCC-Ranch-CrewAll this work couldn’t have been done without the help of our ranch manager, Stanley Hartman (4th rider from the left). He’s been at the helm of the ship for 13 years now. Justin Boatright is Lone Mountain Cattle’s new herdsman, taking care of all our animals now for almost a year.

Finally, stay tuned for the launch of the new Lone Mountain website – we are putting the final touches on it now – with the able assistance of both Nellie Stadherr and Michael Beattie.

We look forward to seeing and meeting you this coming May. Please reach out to for the latest updates.

Ono’s Tale of Two Prefectures

February 5, 2014 by LMCC

Here is a brief introduction to both the Kedaka line of Tottori Prefecture and the Dai 7 Itozakura line of Shimane Prefecture (with a mention of Okayama Prefecture’s claim on Dai 7 Itozakura).

The Kedaka line started, appropriately enough, with the birth of bull Kedaka, himself, in Tottori Prefecture in 1959. Kedaka produced a number of fine lines and bulls, including the Harumi line (Shimane Prefecture). Kedaka cattle were bred as pack animals, so they were valued for their ability to transport things (produce, in this case) over great distances, rather than their ability to do heavy work over short distances. There was less of an emphasis on farm chores in Tottori Prefecture as there was in Hyogo Prefecture, so the cattle were built differently. Tottori Prefecture cattle didn’t need large forequarters but did need to be good grazers. Good grazing meant strong mothering instincts, something the Harumi line is widely appreciated for.

The Dai 20 Hirashige line, established in 1974, is the most famous offshoot of Kedaka’s genetics.

Interestingly, Dai 20 Hirashige is the product of a father-daughter mating. As a result, his “inbreeding coefficient” is 25 percent, at a minimum. An inbreeding coefficient estimates the percentage of identical genes that have been inherited or are likely to be inherited from an offspring’s parents.

An inbreeding coefficient can range from 0 to 100 percent, but 25 percent is considered to be high. Ideally, the inbreeding coefficient should not be higher than 12-15 percent. The higher the inbreeding coefficient is, the greater the risk of mortality or abnormality in offspring. On the other hand, a higher inbreeding coefficient can enhance the positive traits of the two parents in the progeny.

It’s a roll of the genetic dice, but often the potential benefits are judged to be worth the possible risks.

For more information about inbreeding, line breeding and inbreeding coefficient, click here.

As the 20th century progressed, Tottori Prefecture began to provide more bulls for other prefectures — and even other continents (namely, Australia) — than it did for itself. In fact, some of the finest Tottori lines were launched outside of Tottori. For example, Hirashigekatsu, of Kagoshima Prefecture, is one of the best and most balanced bulls in current use. Taro Araki, publisher of Beef Cattle magazine, has said that Hirashigekatsu is an ancestor of half the cows in Japan.

Today, Tottori is trying to get some of its genetics back to bolster its own herds.

The Kedaka chart is as follows:

Kedaka Line

The Dai 7 Itozakura line is really two lines and two prefectures joined by a common ancestor: Dai 14 Shigeru. In Shimane Prefecture, Dai 14 Shigeru (who was born in Okayama Prefecture) was paired with a Tajima dam to create Dai 7 Itozakura. In Okayama Prefecture, descendants of Dai 7 Itozakura — Dai 6 Fujiyoshi, in particular — were used to create the Fujiyoshi line.

As Shogo Takeda wrote in the August 2007 issue of the Australian Wagyu Update, “People from Okayama Prefecture insisted that Dai 7 Itozakura originated from the Okayama line. This is because Dai 7 Itozakura’s sire (Dai 14 Shigeru) was born in Okayama. On the other hand, people from Shimane Prefecture insisted that Dai 7 Itozakura originated from Shimane, as his maternal lines originated from Shimane.”

Confusion persists.

Dai 7 Itozakura’s most famous son is, perhaps, Kitaguni 7-8, whose mother was a Kedaka dam. Thus, Kitaguni 7-8 was a Dai 7-Kedaka composite bull.

The Dai 7 Itozakura (Shimane) chart is as follows:

Line Breeding vs Inbreeding

February 5, 2014 by LMCC

Inbreeding is the mating of animals that are closely related to each other. Outcrossing is the mating of animals that are totally unrelated. Somewhere in the middle lies line breeding. What constitutes inbreeding and what constitutes line breeding is in the eye of the breeder.

Line breeding is highly strategized inbreeding. It is breeding to close relatives in order to lock in desirable traits. Line breeding seeks to convey outstanding genetics from one generation to another while minimizing the transfer of undesirable traits.

A so-called half-sib mating (half brother to half sister) is a popular form of line breeding.

The difference between inbreeding and line breeding lies in the degrees of separation between one half of a breeding pair and the other. Inbreeding means mating father to daughter, mother to son, and brother to sister. Line breeding involves mating more-distantly related animals, although there is a conventional wisdom that says line breeding is whatever works and inbreeding is whatever doesn’t.

The grandfather of animal breeding is 18th-century English agriculturalist Robert Bakewell. Bakewell was the first to turn away from a random approach to breeding that had ruled the roost (and the pasture and the barn) for centuries. Bakewell took control of the breeding process and introduced inbreeding (then known as “close breeding”) as a way of locking in and magnifying desirable traits.

Bakewell believed in finding the best and mating it with the best. Everything breeders do today owes a debt to Bakewell.

The terms “inbreeding coefficient” and “coefficient of inbreeding” both refer to a mathematical formula devised by the late geneticist Sewell Wright. It is used for determining just how close, genetically, certain animals are. The inbreeding coefficient (IC) calculates the probability that “both genes of a pair in an individual are identical by descent,” according to a definition that has been shared online by breeders of alpacas, pit bulls and many other disparate animals.

What is considered high varies from animal to animal, and breed to breed. In racehorses, an inbreeding coefficient of 5 percent is considered high. In Wagyu, it’s anything over 15 percent. The higher the percentage, the greater the potential benefits and risks. In Japan, especially in Hyogo Prefecture, intensive and extensive line breeding over the course of several hundred years has been used on Wagyu to lock in certain traits.

At first, Japanese breeders were just trying to create the best draft animals. They had no way of knowing, of course, that the physical traits they appreciated in cattle raised for work would one day be the same traits that breeders would appreciate in cattle raised for beef.

Hyogo Prefecture’s aggressive and long-lived line-breeding strategy was cast into high relief in a 2006 calf-market survey of 62,000 Japanese Black Wagyu. The average IC at the Hyogo Prefecture market was a whopping 21.7 percent, whereas the average IC for Tottori calves (Tottori being a prefecture where outcrossing has been practiced of late to a much greater degree) was 6.8 percent.

Harvest News From Lone Mountain Cattle Company

February 3, 2014 by LMCC

On December 2, 2013 we harvested 1248Y, a 29 month old sired by Kitaguni Jr.. As seen in the ribeye carcass photo below, 1248Y proved to be of great quality.

Kit x Itohana2_Dec13_027Steer LMR Kitaguni 1248Y Ribeye 13Jan14

As did, 1257Y, a steer by Yasufuku Jr.

Steer LMR Yasufuku 1257Y Ribeye 13Jan14

LMR Kitaguni 1248Y’s Dam (LMR Ms Itohana 9229W) was sired by TF Itohana 2 out of a Sanjirou cow.

What might be surprising to some is that 9229W, the mother,  is an AFFECTED F11 cow – Homozygous for F11!

So of course, 1248Y was a Carrier (Heterozygous) for the F11 gene.

Not really surprising to us, since AFFECTED cows mated to FREE will always produce a CARRIER calf. That information might come as a surprise to those producers who have continually shied away from F11 Carriers.

So if it is really all about the meat in the final analysis, then this picture should put those doubts to rest.

What a treat to get a 44.53% IMF measurement from a LMR FB Carcass – much less the progeny of an AFFECTED Cow!

While we are at it – LMR Yasufuku 1257Y – a Yasufuku Jr steer, was harvested and computer calculations read 39.8% IMF (see photo above). It so happens that 1257Y was a CL16 Carrier.

All around, a good day for Lone Mountain – and an educational one at that!

Takeaway: Do Not Be Frightened of Genetic Results – Management is Your Friend!

Kenichi Ono wrote the book on Wagyu…literally.

December 17, 2013 by LMCC

For years, I had seen and heard references to Kenichi Ono’s three-volume series Outstanding Wagyu of Japan, but I had never been able to obtain my own copies. I sent inquiries to a mailing address in Japan, but they were evidently ignored or misdirected. Ono’s series was the definitive work on the genetic history of the Wagyu breed, so I was understandably frustrated.

Then, while in Yonago City, Tottori, attending the 9th Zenkyo (the All-Wagyu Show held in a different Japanese city every four years), I happened upon a booth selling books. Though unable to speak Japanese, I managed, through halting inquiry and serendipity, to stumble across stacks of books that looked as if they might be Ono’s work. They were sizable and had photos of Wagyu bulls on them.

As it turned out, I had indeed hit the jackpot.

After returning to the States, I contacted a translator named Yugo Osugi, and we have been collaborating ever since. I was able to find a fourth volume of Ono’s series while visiting the 10th Zenkyo in Sasebo, Nagasaki, in 2012.

What follows is a series of blog posts exploring Ono’s work. In this introductory section, I will lay out some basics.

I am indebted to Mr. Ono and Ms. Osugi, of course, as well as to all the people who have more-substantial credentials than I do — and who have already accomplished aspects of what I am about to attempt. They include professor Kiyoshi Namikawa, Mike Buchanan, Tak Suzuki, David Blackmore and Charles Gaskins, plus many others.

The origins of the Wagyu breed stretch further back than most people realize, and further back than I could possibly do justice to here.

The earliest written reference to Wagyu dates to about A.D. 1310. I will begin considerably later than that here, with Naka-Doi, a sire born in 1920.

It has been said that 90 percent of today’s Tajima-Hyogo line descended from Naka-Doi. But there is a considerable amount of controversy and confusion regarding whether a sire named Tajima even existed. Tajima may in fact refer to the area of origin. Ono makes no reference to a sire named Tajima in his works.

Tajiri, born around 1940, was unquestionably the most important descendant of Naka-Doi. The chart below simplifies the lineage of Naka-Doi and Tajiri in a manner that, ideally, is easy to understand.

Ono refers to Yasafuku J930 as a subset of the Yasutani-Doi line. What follows is a short guide to the Tajima-Hyogo line and the various strains that fall within that line.

Major Tajima-Hyogo Line Chart

Major Tajima-Hyogo Lines (Click to Enlarge)

The Yasumi-Doi line, begun in 1971, can be categorized as two types. The first is represented by such sires as Yasutani-Doi, Tadafuku and Yasumikane. The second type is represented by Monjiro. The differences between the two illustrate that classic trade-off between quantity and quality. The former has wide shoulders, and the latter, narrower shoulders. The former has good daily weight gain but its meat is deficient in flavor compared to the latter. Conversely, the latter has excellent flavor but lacks the economic benefits of the former. The bulls of the former are known for being opinionated while the bulls of the latter are known for skittishness. The former are better group feeders than the latter.

Yasumi Doi Line

The attractiveness of Wagyu bulls is not a matter of much debate among cattlemen who do not raise them. But among cattlemen who do, there may be some general agreement about the Yasutani-Doi line: the bulls are not as handsome as other Hyogo Prefecture bulls. They have long foreheads and rough coats. The Yasutani-Doi line, begun around 1976, is not known for consistency in any area. But the best progeny comes from the Yasufuku line, which tends to show the best daily weight gain and meat quality.

Yasutani Doi Line

Yasutani Doi Line (Click to Enlarge)

The Yasufuku line, begun around 1980, is imbued with excellent qualities, including thick shoulders, large loin size and a high yield rate of meat. Kenichi Ono regards this line as perhaps the greatest of all Wagyu. One small quibble is taste. Steady weight gain and early maturation can lead to meat that lacks in flavor as compared to other meat in the Tajima-Hyogo line. Some progeny of Yasufuku, such as Yasufuku 165-9 and Ryunn (Gifu Prefecture), have great meat quality but are susceptible to fat necrosis, which is the destruction of fat cells by digestive enzymes.

Yasufuku Line

Yasufuku Line (Click to Enlarge)

The Kikumi-Doi, or Kikuteru-Doi, line is blessed with a number of admirable qualities. Among them are good meat color and milk volume. The calves are good nursers. But the line has generally been rife with disappointment. These cattle tend to have sluggish weight gain and bad dispositions. They can be generally nervous and specifically ornery. Because of these issues, only a limited number of bulls have been noteworthy. Terunaga-Doi and Nakazutsumi are among the more-marked successes. The weight-gain problem can be mitigated somewhat by using mothers from the Yasutani-Doi and Shigekame-Nami lines.

Kikumi Doi Chart

Kikumi Doi Chart (Click to Enlarge)

On the surface, the Kikuyasu-Doi line seems to have many of the best qualities of Hyogo Prefecture cattle. Among them are beautiful coats and handsome faces (according to Wagyu experts, who know a handsome cow when they see one). But the progeny’s scores are inconsistent. Only a few bulls in this line have been judged successful. They include Kikuyasu and Maruyu.

The Kumanami line originated in 1957 with the birth of Shigekanenami. Unlike the aforementioned four strains, all of which descended from the sire Tajiri, the Kumanami line descended from a female of the Naka-Doi line. Shigekanenami was easily the most popular bull in the Kumanami line. For a Hyogo Prefecture bull of its time period, Shigekanenami had exceptional weight gain and an outstandingly proportioned body. Its progeny had two sets of distinct characteristics: thick shoulders and good daily weight gain (Fukumasa and Otosha 6), and thin shoulders and a lack of hip width (Shigeshigenami).

Bulls descended from Shigeshigenami have the best consistency in terms of meat quality. Despite the superficial shortcomings of thin shoulders and a lack of hip width, the meat quality is typically extraordinary. Shigeshigenami was born in 1972 in Hyogo Prefecture but was sold to Miyagi Prefecture in 1974. In 1983, progeny of Shigeshigenami won first and second place in the “steers” category at a national dressed-carcass competition in Tokyo. Interest from outside Miyagi Prefecture in breeding with Shigeshigenami only seems to grow with each passing year.

The Outstanding Wagyu of Japan

July 25, 2013 by LMCC
100 Greatest Wagyu in Japan, Vol. 1

100 Greatest Wagyu in Japan, Vol. 1

Renowned Japanese researcher Kenichi Ono has written a definitive series of books roughly translated as “100 Greatest Wagyu in Japan.”* I first hunted down his authoritative books during my visit to Japan’s 9th Zenkyo** in 2007. Ono has now published four volumes covering many of the most well known and highly regarded Wagyu cattle, both sires and dams. Volume 1 was published in 1999; Volume 2 in 2001; Volume 3 in 2007; and Volume 4 in 2012, which I was fortunate to find on my visit to the 10th Zenkyo held in Sasebo-Nagasaki in 2012.

The books represent a valuable resource for all Wagyu breeders all over the globe not only for its brilliant writing and scholarly, investigative research, but also for its invaluable insights regarding the breeding of these special beasts. The intention of this article is to raise awareness of Ono’s work – work that we think will be beneficial for all Wagyu breeders. It should be noted that most of the genetic lines considered in these volumes are available not only in Japan, but now worldwide.

Over the course of the following weeks and months, we will investigate and analyze Ono’s detailed descriptions of the major Wagyu influences in all four volumes. Because it is our commitment to preserve and enhance the integrity of the Wagyu breed in America, we will share our findings with you in a series of posts on our blog and e-newsletters.

Revered for its astounding beef and regarded as a National Treasure of Japan, Wagyu has been ushered to this supreme standing in the world by the craft and toil of the Japanese farmer – and they should be valued for their great contribution to the breed.

In Volume 1 there are 15 Wagyu highlighted as the 15 most important in the modern history of the breed – both females and males are listed – and of interest is that 10 of them have passed on genetics that are available today to the Western producer. Many of us in the West have lamented the lack of diversity in our Wagyu herd – but we have much to be thankful for, as you will see in the list below.

Below I have taken the liberty of listing not only the sires and dams noted by Kenichi Ono in his first volume, but additionally the progeny and genetic lines available to producers outside Japan are listed.

The top 15 Wagyu, in Ono’s order, as recorded in Volume One (1999):

  1. Yasufuku J930 – Sire of Yasufuku Jr.; Grandsire of Takazakura
  2. Dai 7 Itozakura – Grandsire of Itohana 2; Itomichi 1-2; Kitaguni Jr.; Itoshigefuji TF147; Itozurudoi TF151; Kikuhana
  3. Kitaguni 7の 8 – Sire of Kitaguni Jr.
  4. Shigeshigenami – Sire of Itoshigenami TF148; Grandsire of Suzutani; Maternal Grandsire of Sanjirou & Shigeshigetani
  5. Dai 20 Hirashige – Sire of Hirashigetayasu ETJ001
  6. Kikutani – Sire of Fujitani; Dam Sire of Okutani; Dam Grandsire of Beijiro
  7. Monjiro – Sire of Michifuku & Haruki II; Grandsire of Sanjirou & Shigeshigetani
  8. Masafuku
  9. Tadafuku
  10. Kamitakafuku
  11. Tanifuku Doi – Sire of Kikutsurudoi TF146 & Kimifuku 3
  12. Kikutsuru (Cow) – Grand-Dam of Fukutsuru 068 & Kikutsurudoi TF146
  13. Mitsufuku (Cow)
  14. Kitaguni 7 (Cow) -– Grand-Dam of Kitaguni Jr.
  15. Kiyofuku (Cow)

Comparison of Feeding Systems Shows Hay-Finishing Could Be Sustainable Alternative to High-Concentrate Fattening

July 23, 2013 by LMCC

With this epic drought in the Southwest and feed prices jumping up every season, we thought this research paper was of interest. It shows a potential solution for bringing producer costs down, nudging the consumer price down, and reducing environmental costs. By using a “high-hay” feeding program (See Image below), the result was a product that surpassed the taste of grass-only beef. While the study didn’t undertake a taste test between the “high-hay” feeding program and the “high-concentrate” feeding system (which we at Lone Mountain use), this research propose a compelling mid-way solution between our current practices and the much-spoken-about grass-fed option that has become increasingly popular in mainstream media. Full Abstract of the article below (and Click Here to Go to the Full Article):

Comparison of Feeding Systems

Comparison of Feeding Systems


The objective of this article is to compare feed cost, palatability and environmental impacts among feeding systems of high concentrate (HC), high hay (HH) and grass-only-fed (Gof) groups. Feed cost was the sum of costs paid for feed intake times the price of feed per kilogram. Palatability was measured by a panel taste test using HH and Gof beef and analyzed for differences. Environmental impacts were calculated based on 1 kg of Japanese beef yield of CO2 equivalents (eq) and animal end weights at each feeding stage. Results showed that the HH and Gof feeding systems could significantly reduce feed costs by approximately 60% and 78%, respectively, from the HC. In the panel taste test, 50% and 47.50% of panelists indicated that HH beef was ‘extremely delicious’ and ‘acceptable,’ respectively, while 15% indicated that Gof beef was ‘extremely delicious’; 62.50% indicated that Gof beef was ‘acceptable.’ Environmental impacts of each feeding system in terms of CO2 equivalents (eq) were 9.32, 6.10 and 2.04 tonnes of eq for the HC, HH and Gof, respectively. The HH was an economical system that produced moderate impacts on the environment and had impressive taste.


Research Shows: Composition of Fatty Acids in Beef Determine the Desired “Umami” of Wagyu Beef

July 23, 2013 by LMCC
9236 Toshiro CU

IMF Photo of Lone Mountain Wagyu Carcass 9236

According to this research paper out of Australia, the “lustre, texture and properties” that are so desired by those consumers purchasing Wagyu beef across the world come from the beef’s specific fat composition.

The Japanese fat had considerably less saturated and more unsaturated fatty acids resulting in much higher unsaturated/saturated ratios (1.9) compared with the Australian samples (1.0). This resulted primarily from the high contents of oleic and palmitoleic acids and the low content of stearic acid of the Japanese samples. The triacylglycerols from the Japanese fat had considerably less tri-saturated and di-saturated fatty acids and more di-monounsaturated and tri-monounsaturated fatty acids in their structure.

In our breedings we aim to produce offspring with increased intramuscular fat percentages (IMF%) because that’s what our customers desire and are willing to pay for. While that objective is clear, breeding towards that goal is complicated, as any seasoned producer can attest to. The SCD genetic test is a step towards simplifying and systematizing this breeding goal – another tool in the breeding toolbox. As written by Dr. Tadayoshi Mitsuhashi, “By using the SCD gene we can select the cattle which can deposit a soft and oleic acid rich fat that is delicious and healthy.”

From the AWA website:

Stearoyl CA desaturase (SCD) is the enzyme which changes stearic acid into oleic acid. The fat of cattle is composed of 6 main fatty acids. Within these fatty acids one of the saturated fatty acids is stearic acid. Stearic acid makes deposited fat harder and increases the melting point. Conversely oleic acid makes the fat soft with a low melting point. Olive oil is an example of a product that has abundant oleic acid.
