Founded in Legacy. Driven by Data” – this mantra encapsulates the mission and vision of the new Legendary Akaushi Genetics. Established in 2015, Legendary Akaushi has been at the forefront of preserving and enhancing the foundation genetics of Akaushi cattle. Recently, the ranch transitioned ownership from Bill Fisher and Jordan Beeman to Steve Cotrelle, marking a new era of innovation and growth while still staying true to the vision of the original founders.

With new ownership, the commitment to preserving these foundation genetics remains steadfast. However, there is also a renewed focus on propelling the breed forward. Leveraging our unique position of owning numerous rare foundational animals, we are poised to create new maternal lines based on rigorous data analysis and performance metrics. This data-driven approach ensures that we not only preserve the legacy of Akaushi genetics but also enhance the breed’s future potential through informed breeding decisions and innovative practices.

History of Akaushi
The Akaushi breed, also known as Japanese Brown or Red Wagyu, has its origins in Japan’s Kumamoto and Kochi prefectures. This breed is part of the larger Wagyu family, which includes Japanese Black, Japanese Polled, and Japanese Shorthorn. Wagyu translates to “Japanese cow,” and Akaushi specifically means “red cow.” The breed’s development began in the late 19th century, following the Meiji Restoration in 1868, which opened Japan to Western influences and led to the introduction of European cattle breeds such as Simmental and Devon to enhance size and maternal traits. In addition to these Western influences, Akaushi cattle also integrated genetics from the Korean Hanwoo, noted for its exceptional marbling and robust flavor. Studies indicate a significant genetic overlap between Akaushi and Hanwoo, with some Akaushi showing up to 80% genetic similarity to Hanwoo cattle, this sets them apart from the Black Wagyu and makes them a great cross for heterosis on these types of cattle. This genetic linkage highlights the distinctive qualities of Akaushi beef, blending the intense marbling with a rich, beefy flavor.

Akaushi cattle were first imported to the United States in the 1970s. This initial import included two Tottori Black Wagyu bulls, Mazda and Fuji, and two Akaushi bulls, Judo and Rueshaw. These early imports laid the groundwork for the Akaushi breed in the U.S. However, it was in the 1990s that a significant expansion occurred with the importation of additional Akaushi cattle. This included both Akaushi and Black Wagyu, but the focus was primarily on enhancing the Akaushi genetic pool. These imported cattle were pivotal in establishing a robust Akaushi population in the U.S., ensuring that the breed’s superior marbling, tenderness, and flavor were preserved and propagated. The Akaushi cattle that were originally imported are mostly tied to HeartBrand Beef, previously known as Englewood. In the early 1990s, the Englewood company recognized the potential of Akaushi genetics and invested in importing and breeding these cattle. Englewood’s efforts were instrumental in introducing and popularizing Akaushi beef in the American market. The company eventually rebranded as HeartBrand Beef, continuing its mission to produce high-quality Akaushi beef. Legendary worked with Heartbrand and Wagyu Saki to build their initial herd of rare Akaushi donors.

Why Use Legendary Bulls
Akaushi cattle offer numerous benefits, making them an excellent choice for commercial herds. Known for their exceptional marbling, Akaushi beef consistently achieves higher quality grades, moving select cuts to choice and choice cuts to prime. This superior carcass quality translates to a rich, buttery flavor and a tender texture, highly valued in the beef market. In addition to their premium meat quality, Akaushi cattle exhibit high fertility rates, calving ease, and robust growth, which contribute to efficient and profitable breeding operations. Another significant benefit of Akaushi cattle is their ability to adapt and perform in various climates. Bred on the volcanic slopes of southern Japan, Akaushi cattle have evolved to thrive on grass and in pasture environments. These environmental condiditions allowed the Akaushi to differentiate themselves from the Black Wagyu as they flourish in more rugged conditions, resulting in a thicker build and weaning weights comparable to continental breeds. Since the Akaushi is more related to the Hanwoo than the Black Wagyu, it is also a great choice for producers who have used a Black Wagyu bulls in the past; as these calves will have a high level of heterosis. It is not uncommon for purebred Akaushi to wean calves weighing between 400-550 lbs, with calves being born at around 65 lbs on average. This unique environment also endowed Akaushi cattle with heat resistance. In Texas, it is common to see Akaushi cattle grazing alongside Brahman-influenced cattle in the summer heat when other breeds seek shade or water. Akaushi cattle also perform well in cold environments, thriving in states like Idaho and even further north in Canada.
Our focus on data-driven breeding practices aims to identify cattle that excel in commercial beef production systems. We are currently investigating feed and water efficiency and plan to develop systems and facilities to measure these traits next year. We believe that Akaushi cattle are ideal for use in tropical climates where Brahman-based cattle are common due to their resilience. Akaushi cattle bring not only resilience but also superior carcass quality to the equation. Starting this year, Legendary will incorporate ultrasound technology to select bulls for our program and for sale to our customers. Advances in ultrasound technology over the past decade have made it a valuable tool in ensuring the bulls we sell will marble efficiently. This data will contribute to producing Estimated Breeding Values (EBVs) through the Australian Wagyu Association, where our cattle will be compared to Black Wagyu. Although Australia has a robust system for EBVs in Black Wagyu, it may take 3-5 years for the data to accurately reflect the performance of Akaushi. We expect to have the results of the ultrasound scans available by the next breeding season, contributing to ongoing studies comparing Akaushi to Black Wagyu.

By choosing Akaushi bulls, you can significantly improve the quality of the carcasses produced by your herd. This improvement is particularly advantageous if you run a farm-to-table beef program or sell cattle on the grid. In the past year, premiums for F1 calves have decreased, but we anticipate these premiums returning once cattle prices stabilize from their current all-time highs. Investing in Akaushi genetics positions your operation to capitalize on these future market opportunities, ensuring consistent production of high-quality beef that meets consumer demand for superior marbling and flavor. At Legendary Akaushi Genetics, our dedication to preserving the rich legacy of Akaushi cattle while driving the breed’s future through innovation and data-driven practices sets us apart. Our commitment to quality, sustainability, and excellence positions us at the forefront of the beef industry, offering unparalleled value to our customers and the market. By choosing Akaushi bulls from Legendary Akaushi Genetics, commercial cattlemen can enhance their herds with superior genetics, ensuring higher quality beef, improved efficiency, and greater adaptability to diverse environments.

Managing nuisance insects can be challenging without the appropriate products and integrated pest management strategies. Over time, Central Life Sciences has expanded its product range to include additional solutions for combating flies, fire ants, cockroaches, and other pests labeled as threats to your operation. Offering diverse solutions, we provide the necessary products to combat harmful insects prevalent in your environment.

Flies

Flies are more than just a nuisance on operations; they can significantly impact productivity and profitability without effective control measures in place. Managing diseases transmitted by flies requires employing various methods such as fly traps, baits, and

on-animal treatments to curb fly populations. For instance, house flies, stable flies, face flies, and horn flies are significant concerns in dairy operations due to their ability to transmit over 65 disease-causing organisms, contributing to ailments like Salmonella, mastitis, and pinkeye among cattle.

Central Life Sciences’ ClariFly® Larvicide and Altosid® IGR offer producers protection against the damaging impact of flies. The products don’t directly affect production but provide control for the nuisance flies that do. Both product lines are mixed into cattle feed and passed through the cow’s digestive system and into manure, where they interrupt the life cycle of the fly, preventing development into the adult stage. The active ingredient in each provides target-specific modes of action that are not harmful to birds, fish, reptiles, mammals, or beneficial insects.

When proper fly control isn’t in place, your animals can become stressed and uncomfortable, ultimately lowering overall productivity and profitability. 

Numerous species of flies can be a nuisance to your operation. They can not only annoy animals and humans alike but also affect animal comfort, health, and profitability. By implementing an Integrated Pest Management (IPM) program with Starbar®, ClariFly® Larvicide, and Altosid® IGR products, you can protect your operation from costly fly infestations.

Cockroaches

Cockroaches, often overlooked on agricultural operations, pose significant threats to cattle, employees, and the bottom line. Besides contaminating food and spreading diseases, they act as reservoirs and mechanical vectors for various illnesses. Transmission of these diseases includes inhalation, digestion, and cross-contamination. Not only does this affect humans, but it also affects cattle. Some of the diseases and bacteria cockroaches spread include Sarcocystosis, Salmonella, and Listeriosis.

Sarcocystosis is a disease often found in cattle, and they can contract it through ingestion after cockroaches contaminate their food. Signs of illness in cattle may include weakness, muscle spasms, weight loss, abortions, and possibly death.

When roaches crawl in filthy places, they compile Salmonella. After remaining in their digestive system for about a month, it can be transferred and released through their vomit and droppings. Salmonella can cause a wide range of clinical signs in cattle, such as joint infections, abortion, dysentery, chronic pneumonia, and sudden death. This disease is also commonly transmitted to animals by contamination of feed and water but can be found anywhere, such as in animal bedding gates and pens.

Listeriosis is a bacterial infection of the brain, and it can affect a wide variety of animals, including cattle, birds, pigs, and humans. While this disease affects the nervous system, it can lead to other problems such as stillbirths, abortion, and encephalitis. The ingestion of bacteria causes most infections. However, direct contact or inhalation with the bacteria can also cause infection.

Products such as Cyanarox® Insecticidal Bait and Exhalt™ WDG Insect Growth Regulator from Starbar® allow you to protect your operation from the dangerous and costly effects of cockroaches.

Fire Ants

Fire ant infestations can irritate your cattle, causing reduced weight gains and injuries. Even more concerning, stings from fire ants can harm or even kill livestock, especially the young. When fire ants settle into pastures, they often forage for food or moisture in the same areas where livestock graze, according to NC State Extension Publications. 

Extinguish® Plus is the best answer to any fire ant problems on your operation. Extinguish® Plus was designed to offer both short-term and long-term relief from fire ants endangering pastures and livestock. It combines the killing power of an adulticide, Hydramethylnon, and the long-lasting control of the insect growth regulator (IGR), (S)-methoprene.

The dual action of an adulticide and an insect growth regulator (IGR) in Extinguish® Plus kills worker ants and sterilizes the queen, resulting in a one-two punch for fire ants, a quick reduction of mounds, and the confidence that the ants will be completely extinguished through the IGR. Extinguish® Plus is approved for use where cattle graze with no worries about withdrawal periods.

With Extinguish® Plus by your side, you’ll start to see fire ant colonies dwindle in about one week. And the entire colony could be eliminated within as little as two weeks.

Ticks

Because cattle often live and congregate closely together, ticks can multiply and spread rapidly, allowing some insects to turn into a tick infestation on cattle quickly. These blood-sucking insects spread diseases to both humans and cattle, hindering performance and bottom lines.

To effectively protect livestock from ticks, it’s essential to follow a checklist:

Regularly check livestock for ticks in key areas such as the head, ears, brisket, trailhead, udder, and between the legs. Report any findings to the local health department or state animal health official for further guidance and monitoring. Be vigilant for symptoms indicating tick-borne illnesses, such as high fever and weakness, and seek veterinary care promptly if observed. Additionally, maintain pasture hygiene by cutting down brush or weedy areas, reducing tick habitat, and minimizing exposure risk for livestock.

For effective tick control, use a product like Prolate/Lintox-HD™ Insecticide. Able to be used as a pour-on, mist spray, or in a backrubber, its synergized formulation provides effective treatment of ticks.

Lice

Lice can cause intense irritation and affect the appearance of livestock due to rubbing and scratching. Many lice species affect cattle, but the main ones are either biting or sucking lice. Biting lice feed on skin debris while sucking lice suck blood and can cause anemia if infestations are heavy enough. 

By killing listed parasitic flies and controlling lice, Inhibidor™ Insecticidal Pour-On can enable more efficient production by keeping your animals comfortable while protecting your bottom line. Other products for lice control include Cattle Armor™ 1% Synergized Pour On, Starbar® UL-100 EC Insecticidal Spray, Prolate/Lintox HD™ Insecticide, Starbar® E-Pro Adulticide Spray, and Pyronyl™ Crop Spray.

Central Life Sciences understands the detrimental losses that these insects pose to cattle, employees, and your bottom line. With products scientifically tailored to insect behavior at pinpoint locations, our Starbar®, ClariFly® Larvicide, and Altosid® IGR products can help you keep your cattle healthy and comfortable all season.

Transforming Cattle Health and Profitability with Horn Fly Management

Transforming Cattle Health and Profitability with Horn Fly Management

Found on the backs of cattle, horn flies are the most pervasive and costly external parasites of cattle in North America, taking up to 40 blood meals a day. Losses from horn flies cost the industry an estimated $1 billion each year due to the stress they inflict and diseases they spread to cattle. Using a fly management program to limit flies on cattle will help promote herd health.

The Impact of Horn Flies

Effects from horn flies on cattle include:

 • Irritating cattle with their painful bites causing cattle stress and annoyance

 • Burning excess energy to dislodge flies and cattle bunching, leading to interrupted grazing patterns

 • Reducing weight gains and calf weaning weights  

 • Decreasing milk production

The diseases that horn flies spread to cattle, including beef heifer mastitis, can be linked to lower conception rates. Studies have confirmed that cows with infections can take 25% longer to conceive. 

Beef heifer mastitis is a potentially devastating issue for cattle herds, as it can quickly spread and have a significant impact on both animal health and your bottom line. Mastitis, characterized by the inflammation and infection of one or more teats, often leads to the development of blind quarters. This condition, while often overlooked, can destroy the milk-producing tissues within the affected teats, ultimately resulting in decreased milk production and reduced weaning weights.

Central Life Sciences Product Shoot, Texas, April 2023

Horn flies are known to feed on the blood vessels in the skin of the teats, causing irritation and creating a gateway for mastitis-causing bacteria. Horn flies can carry these harmful bacteria from one animal to another, entering the teat orifice and moving upward within the quarter, where they inflict damage on the milk-producing tissues. These flies only leave the animals to lay their eggs in fresh manure, perpetuating the cycle of infection and infestation.

According to Dr. Nickerson at University of Georgia, 75% of all heifers have mastitis before they calve. He attributes 50% of that mastitis to the horn fly. By implementing an effective fly control program and incorporating Altosid® IGR to help prevent cases of mastitis, you can improve the overall health of the herd, particularly among the heifers.

The Horn Fly Life Cycle

To better control fly populations and protect against cattle diseases, it’s essential to understand the horn fly life cycle:

 • Day Zero: Female adult flies leave the backs of cattle briefly to lay their eggs in fresh manure.

 • Day 1-2: Eggs hatch into horn fly larvae.

 • Day 3-8: Larvae molt into pupae.

 • Day 9-17: Pupae molt into adults.

 • Day 18-40: The adult horn fly emerges as a small, black insect, approximately 4 millimeters long. The adult can live anywhere from 2 to 4 weeks.

While the total life span of horn flies is slightly longer than one month, their populations expand quickly, causing infestations. In untreated herds, fly infestations can increase rapidly to upwards of 4,000 flies per animal.

Implementing proper practices and preventative fly control strategies is key to protecting your herd and profit from horn flies. Altosid® IGR is a feed-through fly control solution that passes through the digestive system and works in cattle manure where horn flies lay their eggs, limiting future populations from emerging. The active ingredient in Altosid® IGR mimics naturally occurring insect biochemicals that are responsible for insect development. The most effective way to control fly populations is to interrupt their life cycle. And Altosid® IGR, from Central Life Sciences, does just that while also eliminating the expense, labor and stress on your cattle associated with other fly control methods.

The 30/30 Program

Disrupting this life cycle is an essential component of controlling horn flies. By adding Altosid® IGR 30 days before fly emergence and continuing throughout the season until 30 days after the first frost, you can help prevent the spread of infectious diseases in cattle. 

The 30/30 Program recommends the use of Altosid® IGR to control fly populations. Producers should start including these products in their feed or supplement early in the spring, 30 days before flies begin to appear through 30 days after the first frost when cold weather reduces or ends fly activity. This time frame ensures an ideal window of treatment with the products, protecting against an unpredictably early or late start to the spring or winter seasons.

To limit the population of overwintering flies that emerge in spring and mark the start of fly season, producers should follow the key steps of the 30/30 Program:

 • Begin feeding Altosid® IGR 30 days before average daytime temperatures reach 65° F.

 • Continue the process until 30 days after the first frost in the fall.

Numerous studies have highlighted the severe economic damage that flies can cause to both dairy and beef operations. Therefore, it is essential to control fly populations. By adopting a “30/30” approach, producers can get ahead of the fly population in the spring before it builds up to a level that exceeds the economic threshold.

By continuing to feed 30 days past the average first frost date in the fall, producers can reduce the total number of overwintering pupae, giving them a head start on the population for the following year. When incorporated into a complete Integrated Pest Management (IPM) program, the use of Altosid® IGR with a “30/30” approach can help producers account for the unpredictability of the seasons and significantly lower fly populations while increasing cattle comfort and profitability.

Integrated Pest Management

The key component to start any IPM program is the initial Planning phase, which includes the identification of problem pests, understanding their habits and devising a management strategy. Once the target pests have been identified, a successful IPM strategy must advance to the Implementation phase, approaching pest control through a combination of several complementary methods.

To have a complete program, one should include several of the following tactics:

Central Life Sciences Product Shoot, Texas, April 2023

1. Improve cultural practices to reduce fly resting, feeding, and breeding sites through regular cleaning and upkeep of facilities and surrounding vegetation. Effective fly control begins with cultural practices, particularly in managing cattle manure. Flies breed in manure, emphasizing the importance of proper manure management.

2. Incorporating natural enemies of flies, such as parasitic wasps and predatory beetles, constitutes biological control. This method helps limit fly populations without adverse effects on animals or humans. By enhancing the ecosystem’s natural balance, biological control is an eco-friendly approach to pest management.

3. Incorporate various physical techniques, like fly traps and sticky tapes to remove adult flies that migrate from surrounding areas and help monitor the amount of fly activity.

4. Using targeted products to control flies like Altosid® IGR, a feed-through fly control product. This product delivers a key active ingredient to cattle, disrupting the fly life cycle in manure and preventing the emergence of adult horn flies.

While establishing a solid Integrated Pest Management (IPM) program is crucial, the journey doesn’t stop there. Ongoing monitoring is just as vital. Regularly assessing fly populations using speck cards and fly traps allows cattle operators to fine-tune their strategies, maximizing control efforts. 

For maximum effectiveness, Altosid® IGR should be used as the foundation of an Integrated Pest Management (IPM) program, including proper sanitation, maintaining physical structures, incorporating naturally occurring fly enemies and using chemical controls. Given the role flies play in cow health and conception, implementing proper practices and preventative fly control strategies is key to protecting your herd and profit from horn flies.
