World Class Black Wagyu AI Sires

Introduction- Top Ranked High Accuracy EBV Sires

Until recently, fullblood Japanese Black sires were generally categorised in the Australian Wagyu breeding community as either ‘growth’, or ‘marbling’. Given the keen focus on F1 breeding in early Australian production, ‘growth’ sires were historically used for building frame in F1 herd bulls, in which the real marbling target was addressed by including high percentages of Tajima (Hyogo Prefecture) bloodlines. Very little or no emphasis was placed on the breeding of consistent, high performance fullblood breeders.

Today, with a commercially viable fullblood sector and new carcass-data enriched BREEDPLAN EBVs supporting superior selection, a small, third category of more versatile fullblood sires is emerging: delivering enhanced early growth to meet the needs of feeder producers, but maintaining consistent high marble scores, and maximised carcass profitability. And in parts of this group, excellent progeny predictability is now apparent not just for feeder growth or carcasses, but also for production of a new generation of more versatile dams.

So the Australian FB sire selection landscape has changed. And the key sire selection categories are:

Terminal sires: For either F1 or fullblood production, promising improved marbling outcomes in vertically integrated production when breeding 100% feeder/slaughter groups, – but often with poor trait development predicted for breeder replacement, and poor early growth predictions for cow/calf producers who sell feeder animals. This terminal sire group is currently identified in the Australian Wagyu Assn FTI (Fullblood Terminal Index), discussed in more detail on this site here.

‘New Generation’ All-Round Performance Sires: As defined in the “All Round Sire Selection Parameters” table below, these sires are capable of delivering early growth performance for feeder producers, commercial carcass performance for feedlotters and processors, plus a new generation of quality breeders.

Traditional ‘Growth/Frame’ Sires: This group comprises largely ‘original import’ sires in the first generation of the Australian and US fullblood Japanese Black herds, used for building frame in otherwise ‘high Tajima’ herd bulls, often in terminal production.

Identifying Key Traits For New Generation All-Round Performance Sires

Unlike the Terminal sire, where the emphasis is heavily on the endpoint carcass marbling, and there is little or no consideration given to early growth or maternal traits, the ‘All-Round’ fullblood sire must deliver key benefits in each of three segments in the fullblood Wagyu supply chain.

– For the cow/calf operator producing feeders and replacements, the cost and time of getting a feeder steer or heifer to feedlot induction weight is a key profitability determinant, so weaning/200/400 day weight performance is mission critical. This requires maternal (milk) traits and solid growth

– For the vertical producer, 600 day weights, carcass weights and marble score will determine final profit/loss.

If the cow/calf operator delivers feeders that do not perform at the feedlot, the future of the both businesses is jeopardised. But for the cow/calf operator, producing feeders to a low-growth, high marbling Terminal Sire may be an even faster route to insolvency.

Following is a snapshot of key traits:

Importance of EBV % Accuracy Values

Wagyu BREEDPLAN EBVs are compiled from thousands of individual animal records. The more records, the more accurate the EBV prediction is likely to be. To assist users, ABRI provides the following guidelines to the use of the %ACC values used in individual animal EBV records.

Accuracy range Interpretation
less than 50% Low accuracy. EBVs are preliminary and could change substantially as more performance information becomes available.
50-74% Medium accuracy, usually based on the animal’s own records and pedigree.
75-90% Medium-high accuracy. Some progeny information included. EBVs may change with addition of more progeny data.
more than 90% High accuracy estimate of the animal’s true breeding value.
“EBVs Explained”. Accessed 27 November 2015

Given the high cost of error in selecting Wagyu sires, we suggest a minimum entry point of 75% accuracy in EBVs to support selection at a commercial level of joinings. A further hidden factor in evaluating Wagyu BREEDPLAN EBVs is the notation at the bottom of each animal pedigree on the AWA site: ‘Statistics: No of Herds’. No measurement indicators are provided, but if an animal’s performance is based in just one herd, then no versatility is demonstrated and other factors may be in play. To quote a prominent geneticist: “if there is only one herd of record, maybe buy 20 straws instead of a thousand, first up.”

Using BREEDPLAN EBVs To Select The ‘Best All-Round’ Japanese Black Sire

The next step is to define a 75%ACC ‘All Round’ sire short list. As we are looking for an AI sire, an obvious pre-requisite is that the sire must have ‘semen available’ – generally noted in its AWA listing, and a selectable field in the EBV search.. In applying individual EBV values, especially in the area of Marble Score, given the small increments in values (often 0.1 steps) our search regards a value of +0.1 as double the value of a ‘Breed Average’ value of 0.0, which itself equated to an AUS-MEAT marble score of MS 7.8.

The following Australian Wagyu Association EBV tables demonstrating this search for specific sire performance are used in accordance with the published guidelines of the developer, ABRI. ABRI stresses that these EBVs were compiled from data supplied by breeders and neither AWA nor ABRI oversee or audit the collection of the data.

Marble Score Selection

We start with marbling as the premier Wagyu requirement, noting that this single carcase trait focus is a ‘Terminal Sire’ search. The four sire summary below is the total short list that the AWA database delivers in a search for ‘sires with semen available’ with a minimum 75% accuracy for a minimum Marble Score EBV of +0.2 or more. We are aware of a few more with semen availability that are not advertised. 0.0 is the 2013 drop Marble Score EBV average.

At the search date there were about 50 Australian registered Japanese Black sires with a 75%ACC Marble Score EBV +0.2 or better, but only this four with ‘semen available’. At 95%, Kitateruyasudoi (003) has the greatest %ACC and can be regarded as highly reliable. Like many of the other 40+ high marble score EBV sires, three of these semen-available sires also show negative 200/400/600 day growth values related the 2013 breed average.

Carcass Weight Selection

In a terminal sire index, and in FB production generally, the second most valuable trait is CWT (Carcase Wt). The two sire summary below comprises AWA’s very top ranked two sires for this trait with these parameters: CWT +29 or more at minimum 75% accuracy, with semen available. Only one of the two has a positive (+) Marble Score EBV value, and B901 is also a son of Hirashigetayasu.

Early Growth Selection – 200/400/600 Day WT EBV

This is the key profit driver in cow/calf operations where feeders are sold on weight. The table below identifies the top ranked three Japanese Black sires (recorded by AWA as ‘with semen available’) in Australia sires for early progeny growth at each of the 200 (EBV +25 or more), 400 (EBV +34 or more) and 600 (EBV +38 or more) day measurement points, with a minimum 75% accuracy.

Superior growth at 200-400 days delivers calves to market earlier, and potentially at significantly less feed cost. The 200 day value is also an indicator of dam maternal capability. The Terminal Index value here is insignificant, but only one sire, B901, has a positive ‘+value’ for marble score.

Best All Round Sire Selection – With (or without) Semen Available

We then combined all of the above searches, retaining minimum 75% Accuracy, but then also removed the requirement for ‘semen is available’, so in theory we would get ‘top rank in entire herdbook’ for a Japanese Black sire.

The considerably less rigorous parameters selected for this search were: Double or more the 2013-Born Breed Average EBVs for 200, 400 & 600 day weight; double or more carcass weight and marble score breed averages (at increments of 0.1). Only one sire came up. Then we added a minimum five times the breed average for Milk (@>65%ACC). And we got the same sire again: Ginjo MarbleMax™ Hiranami B901.

Under the parameters tested above, this sire can stake a highly credible claim to ‘best all round’ AI breeding selection by Wagyu BREEDPLAN EBVs.

Picture: Outsanding all-round Australian AI sire Ginjo MarbleMax™ Hiranami B901

Overview

Ginjo MarbleMax™ Hiranami B901 is perhaps the most versatile, high performance Japanese Black AI sire currently available in Australia. His progeny are proven in local feedlot conditions, primarily AACo Aronui, Dalby, Qld. In Wagyu BREEDPLAN assessment, using higher accuracy (75% or more) values, his progeny are predicted to deliver higher performance for cow/calf operations targeting feeder production through strong early growth, then carrying on to culminate in similar performance in the feedlot processor environment, with well-marbled, large carcasses. Maternal traits (Milk and 200 day progeny weights) suggest equally strong performance as a sire of productive replacement heifers offering their own growth and marbling heritability.

Historical Rankings Summary

Ginjo MarbleMax™ B901 was the outstanding Australian-bred performer in the New Age (Beyond BMS 9) carcass performance revealed at the 2012 Australian Wagyu Association annual conference, Gold Coast. In this instance, marbling was the sole assessment criteria. The local sire achieved #2 overall ranking for a single superfine marbling progeny carcass as assessed by digital imaging over the previous 12 months on major Australian fullblood processing lines. This was well ahead of his own sire, Hirashigetayasu, a holder of Hongen (supreme performance) status within the Japan Registry (ZENWA), prior to export. Hirashigetayasu is also the only international Japanese Black sire to have a known Japanese progeny test.

Superior B901 progeny performance was confirmed in succeeding year, within new Research EBVs tabled at the 2013 AWA Conference in Geelong, Conference (Dr Robert Banks, AGBU: ‘Genetics & Genomics for the Wagyu Breed in Australia – A springboard for growth and profit’). These draft EBVs enabled broader comparison than the single-focus 2012 marbling fineness ranking, including EBVs for carcass weight (CWT), Carcass AUS-MEAT Marble Score (CMAU), Carcass Camera Marbling % (CCMP), Carcass Camera Rib-eye Area (CCRA), and CCFI (Carcass Camera Marbling Fineness Index). Extracted below is the comparison of Ginjo B901 with his sire, the highly ranked Japanese-born Hirashigetayasu.. The three left-hand columns provide dataset record totals for progeny, carcass weight progeny and number of camera image progeny.

The AWA 2014 Research EBV Sire and Dam Summary listing again provided significant ranking to B901 for marbling, inexplicably based on AUS-MEAT MS 1-9 (CCMP being the better objective marbling measure) and CWT. Without disclosure or explanation, this 2014 ranking mixed fullblood, purebred and crossbred carcasses and included ‘progeny records’ from sires with neither ‘registered progeny’ nor specialist carcass assessment camera images supporting carcass rankings (in other words, low level producer carcass feedback level of detail only). Nonetheless, even without any resolution of the Summary parameters dilemma, comparison of 2014 Sire Summary listed sires by both Marbling and CWT ranking again put B901 into high contention as among the top economic performers, as is now more conclusively demonstrated by the November 2015 BREEDPLAN EBVs. The ‘mixed dataset’ described above continues to be applied in Wagyu BREEDPLAN and the FTI (Fullblood Terminal Index).

In actual progeny carcass results, B901 has demonstrated highly consistent marbling around AUSMEAT score 8-9, with HSCW (hot standard carcass weight) averaging over 440kg (~530kg) so far. Superior weaning weights and performance during early growout are features attractive to feeder producers. He represents an exceptional choice for efficient fullblood feeder production both feeder producers targeting weaner sales and for vertically integrated operators targeting superior gross returns. When joining smaller, high Tajima females for feeder production, superfine marbling is a proven deliverable, but high growth may be sacrificed. Results over larger Fujiyoshi/Itozakura joinings are outstanding, as results below illustrate. In the strong post-2012 F1 (cross-breeding) market, B901 is also an economic AI sire option for greater growth and profitability, with B901 sons approved as F1 sires with several Australian feeder/processor and F1 live export systems.

Retained B901 daughters have proven attractive breeding replacements for new generations of larger-frame females with improved maternal capabilities.

B901 is tested FREE of AWA-notifiable genetic defects. Licensed emen is available in Australia and for other international destinations including South Africa. Local stocks are available in the United States and New Zealand.

Additional High Integrity Performance Data

All carcass data was supplied courtesy of AACo, Aronui Feedlot, Dalby. The following additional steps were taken to ensure the highest possible data integrity in assessing B901 feedlot performance.

  • Full sibling benchmark. A full flush sibling was fed/finished to provide a consistency benchmark.
  • DNA verification. All feeder siblings/progeny were University of Queensland parent-verified by DNA. This eliminates the substantial risk of mix-up in commercial registration NM multi-sire programs.
  • AWA Registration. Feeder progeny were/are registered on the basis of DNA parent verification with the Australian Wagyu Association, which exceeds the AWA Commercial registration requirement (see performance tables for registration details).
  • Independent feeding. All feeders were sold outright into Australia’s largest fullblood commercial feeding operation, and finished without preferential treatment of any kind.
  • Independent grading. All carcasses were independently graded on a commercial production line, without any breeder involvement.

We are also indebted to AACo for the nutritional programs that enable a ‘pass’ for the sire in the ultimate ‘commercial reality check’. We are not aware of ANY superior data integrity/veracity regime available for fullblood feeder assessment in Australia.

Selection Process

The B901 progeny target was high pre-weaner growth with zero-supplementation; to set up maximum weaner profitability. This potential is recognised in his Wagyu Group BreedPlan 200 day weight EBV, which is in the upper ranks for the Australian national Wagyu herd..

For the purposes of benchmarking carcass performance for the specific sire pedigree, a full flush brother (Ginjo B906) was sold onto feed with the normal feeder autumn draft sent to AACo, Aronui. This full brother turned in an outstanding result as detailed below, despite a significantly shorter feed period than would be normal under Japanese conditions.

Bloodlines

After Hyogo (Tajima, about 44%), the secondary bloodline in B901/B906 is Tottori/Kedaka (25%), followed by Itozakura/Shimane. MarbleMax B901 then spent his debut 2008 season as a ‘clean-up’ sire in natural mating programs over fullblood females, before semen collection at the Holbrook AB centre in NSW. B901 steer progeny from these paddock joinings, over a random, genetically diverse breeder group, were sold outright into the same feedlot as the B906 sibling. In each case the secondary dam bloodline was Itozakura/Shimane, with smaller Tottori/Kedaka and Okayama infusions. Results are beneath photos.

The Ginjo MarbleMax B901 full flush sibling result at top remains superior to the strong B901 progeny results immediately above, especially given significantly shorter DOF, and this highlights the consistent superiority of the specific ‘immediate relationship’ genetics. Overall, results would be acceptable in Japanese production systems, where the top ADG rivals that of Dai 7 Itozakura progeny, although a higher average steer carcass weight would be sought for a Top 10 Japanese sire.

Ginjo MarbleMax B901 licensed semen is currently available Australia and South Africa, with limited stocks held locally in the United States and New Zealand.

F146 is one of the first 40/1 sons to have semen available in Australia. His sire, Terutani 40/1 is the bull everyone has wanted to use in a full-blood breeding program due to the progeny results under feedlot conditions and also because of the milk and size he is leaving in his daughters. By combining the all round ability of Terutani 40/1 from the Tajima line with the maternal grandsire Itoshigenami TF148 from the Shige Kanenami line, we are bringing into the pedigree the famous cow families of Okutani, Suzutani and Rikitani. The extra marbling ability added by having TF 148 should make this young sire a favourite of breeders of both full blood and commercial crossbred Wagyu. Tested FREE of all 5 recessive genes.* Export qualified semen available $25
