Rise Up Real sits at NVI #1 with an INET of 614 — barely top-10 for production. His Lvd of 1084 carried him past bulls earning €200+ more per lactation. NVI is telling you what it values.
Executive Summary: Rise Up Real vaulted +58 NVI to dethrone Genosource Moti and claim the Netherlands’ #1 genomic spot at +468, April 2026 — but his INET of 614 wouldn’t crack the top 5 on production alone. Every returning bull in the B&W genomic top 10 gained points, yet Halifax Delta Dawn still dropped three spots with a +19 gain because the floor rose +38 in a single run. On the proven side, Genosource Captain jumped +74 NVI on daughter data to land at #2, while December’s #1 Badger Ssi Ahead held position with just a +6 gain. The R&W genomic list is a different animal: 60% churn, six new CRV Delta bulls, and if you’re running a red program without monitoring that prefix concentration, you’re stacking pedigrees fast. CRV now holds 5 of 10 B&W genomic and 6 of 10 R&W genomic slots — pull your mating list and audit sire-line overlap before your next semen order. If you’re still running December-level allocations on Peak Fugleman MW (proven #10 → #56) or Peak Altazingler (#7 → #21), that’s money pointed at yesterday’s rankings.
The April 2026 Dutch NVI genomic run has a new leader. Rise Up Real (Tot) surges from #3 to #1 at +468 NVI, April 2026—up +58 points from his +410 NVI, December 2025—the joint-largest gain among any returning top-10 sire. Bento (GGI), a Bench × Gigaliner son, matched that +58-point leap to vault from #7 to #2 at +450 NVI, April 2026, pushing December’s #1, Genosource Moti (CRV), down to #3 despite Moti himself gaining +27 points.
On the proven side, Genosource Captain (STG) delivers this cycle’s most dramatic daughter-confirmed reranking: +74 NVI, from #9 to #2, at +363 NVI, April 2026. Meanwhile, the Red & White genomic list has been effectively rewritten—six of ten slots are new entrants, all carrying the CRV Delta prefix, led by Delta Bloss-Red at +454 NVI, April 2026. The questions this raises about concentration are worth a hard look.
April 2026 NVI Genomic (B&W): Top 10 Sires
| Rank | Bull | NVI (Apr 2026) | NVI (Dec 2025) | Prev Rank | Δ NVI | INET | Lvd | Stud | Rel |

| 8 | Genosource Benson (Radical) | +429 | +386 | 10 | +43 | 719 | 1251 | CRV | 70% |
| 9 | Chanello (Real Syn) | +427 | New in top 10 | — | — | 639 | 1106 | Indep | 70% |
| 10 | Delta Standout RF | +424 | +394 | 6 | +30 | 661 | 723 | CRV | 70% |
- Remarkably stable top group: 9 of 10 return from December’s top 10; Chanello is the sole new entrant, replacing the sole dropout, Delta Time Jump P (Dec #5, +397 NVI, December 2025 → +403 NVI, April 2026—gained +6 but slid out as the pack surged past).
- Index band shift: The #1 value jumped from +420 to +468 (+48 at the ceiling); the floor rose from +386 to +424 (+38). The entire top 10 lifted substantially.
- Universal inflation: Every returning sire gained NVI. The smallest gain among returnees was +19 (Halifax Delta Dawn); the largest was +58 (Rise Up Real and Bento). A bull that gained fewer than +30 points lost ground in relative rank.
- Re-ordering within a stable group: The real story isn’t churn—it’s reshuffling. Rise Up Real climbed 2 spots, Bento climbed 5, and Genosource Mystro climbed 3. Halifax Delta Dawn dropped 3 spots despite gaining +19 NVI, and Delta Standout RF fell from #6 to #10 with a +30 gain—illustrating how even substantial NVI growth doesn’t hold rank in a rising-tide run.
Big Risers
Rise Up Real (Tot) and Bento (GGI) share the largest gain at +58 NVI each. Rise Up Real, a polled Real Syn × Freewood cross, jumped from #3 to #1 (+410→+468, April 2026). His INET of 614 is below the top-10 median (719), meaning his NVI gain is driven more by functional traits—his Lvd of 1084 is well above average. Bento climbed from #7 to #2 (+392→+450, April 2026) with a more balanced profile: INET 673 and Lvd 1109 both land solidly mid-pack.
Genosource Mystro (CRV) jumped three spots from #9 to #6 with a +45 NVI gain (+386→+431, April 2026). His INET of 881 is by far the highest in the top 10, making him the production standout—but his Lvd of 751 is the lowest, a classic yield-vs-longevity trade-off.
Genosource Benson (CRV) added +43 NVI (+386→+429, April 2026), moving from #10 to #8. A Radical son with the top-10’s highest Lvd at 1251—an extraordinary longevity prediction that, at 70% reliability, still carries re-ranking risk.
Relative Losers: Gaining Points, Losing Ground
In a run where even +30 NVI wasn’t enough to hold position, three December top-10 members gained points but fell in rank.
Genosource Moti (CRV) fell from #1 to #3 despite gaining +27 NVI (+420→+447, April 2026). In a run where the median returnee gained +39, Moti’s below-median improvement cost him two spots. His INET of 743 and Rel of 69% remain solid, but his Lvd of 881 is mid-pack.
Halifax Delta Dawn (Adv) dropped from #2 to #5 with the smallest gain among returnees: +19 NVI (+414→+433, April 2026). His INET of 801 is the second-highest in the top 10, but that production strength didn’t translate into enough NVI uplift to maintain his December position. For herds weighing revenue per lactation, Halifax’s relative slide in NVI matters less than its INET rank.
Delta Standout RF (CRV) fell from #6 to #10 despite gaining +30 NVI (+394→+424, April 2026). His Lvd of 723 is the lowest in the top 10, and his INET of 661 is mid-pack—a profile that didn’t benefit as much from this run’s inflation.
Delta Time Jump P (CRV) is the sole December top-10 dropout, sliding from #5 (+397 NVI, December 2025) to approximately #13 (+403 NVI, April 2026)—gaining just +6 points, the weakest gain among any former top-10 bull.

How Is NVI Rewarding the Current Top 10?
The NVI formula applies a 0.32 multiplier to INET (production euros) but weights UGH (udder health) at 5.5 and VRU (fertility) at 6.5 on their standardized scales, meaning a 1-point gain in health or fertility moves NVI more than an equivalent percentile gain in production alone. This run’s top 10 reflects that weighting:
- Longevity dominates the risers. Rise Up Real (Lvd 1084), Bento (Lvd 1109), Genosource Benson (Lvd 1251), and Chanello (Lvd 1106) all carry Lvd above 1000. Six of ten sires exceed Lvd 1000.
- Production pays differently. Halifax Delta Dawn brings the second-highest INET at 801, and Genosource Mystro leads with an INET of 881—but both sit in the bottom half for Lvd. Halifax trades longevity (Lvd 825) for component yield; Mystro trades it more aggressively (Lvd 751).
- The NVI-INET disconnect is real. Rise Up Real is NVI #1, but his INET of 614 ranks him near the bottom of the top 10. Halifax is NVI #5 but would rank near the top on INET alone. For herds prioritizing revenue per lactation over lifetime performance, the NVI ranking order doesn’t match the production ranking order.

|---|---|---|---|---|---|---|
| Rise Up Real | 1 | +468 | !DROP 9th | 614 | 1084 | NVI #1; near-bottom INET. Longevity carries rank. |

Stud and Sire-Line Concentration
- CRV holds 5 of 10 spots (Genosource Moti, Delta Miller, Genosource Mystro, Genosource Benson, Delta Standout RF)—unchanged from December, when CRV also held 5 of 10 (Moti, Delta Miller, Delta Time Jump, Delta Standout RF, and Mystro/Benson tied at #9–10). Three carry Genosource branding; two carry the Delta prefix.
- GGI holds 2 spots (Bento and Fis Fly P) on different sire lines (Bench and Kings-Ransom), providing internal diversity within the stud’s top-10 presence.
- Outcross options in the top 10: Rise Up Real (Tot, Real Syn × Freewood) and Chanello (independent, Real Syn) both trace to the Real Syn sire line but through different dams and studs. Halifax Delta Dawn (Adv) breaks the CRV/GGI pedigree pattern entirely for herds needing kinship relief.
How Stable Is This Genomic Top 10?
- All 10 sires are genomic with reliabilities of 69–70%. No daughter-proven bulls appear. Every number in this table is a prediction, not a confirmed result. [INTERNAL LINK: Understanding Genomic Reliability — Why Top-10 Lists Change Every Run]
- This is an unusually stable run. Only 1 of 10 is a new entrant (Chanello), and 9 of 10 held top-10 status across both runs. That 10% churn rate is remarkably low for a genomic list at 69–70% reliability—a contrast with the R&W genomic list’s 60% churn this same run.
- Relative anchors: Rise Up Real and Genosource Moti have now held top-3 positions across two consecutive runs. Bento climbed from #7 to #2 over the same span. Delta Miller held #4 in both runs. These four offer the most consistent genomic reliability, though even two runs do not constitute proof.
- Re-ranking within the group matters more than dropout risk this run. Halifax Delta Dawn’s 3-spot drop despite gaining +19 NVI, and Delta Standout RF’s 4-spot drop despite gaining +30, show that relative positioning can shift substantially even when the roster is stable.
NVI Daughter-Proven (B&W) — A Different Top 10

- Badger Ssi Ahead (WWS, 81% Rel) holds #1 at +364 NVI, April 2026, up from +358 NVI, December 2025 (+6 NVI). The modest gain was enough to maintain his position as the field around him shifted dramatically. His INET of 696 and Lvd of 756 represent a balanced, proven profile.
- Genosource Captain (STG, 83% Rel) is this run’s proven breakout: +74 NVI gain, from +289 (Dec 2025, #9) to +363 (Apr 2026, #2). Daughter data massively upgraded his production credentials (INET 725), though his Lvd of 626 is a watch point. [EDITOR NOTE: Captain’s +74 NVI proven gain is a natural spin-off candidate for a sire spotlight feature.]
- Sunrise Superfly Rio (Tot, 77% Rel) gained +52 NVI, from +304 (#6) to +356 (#3). A balanced profile: INET 702 and Lvd 867 are both in the top third of this table.
- Alta/Peak dominance: 4 of 10 carry the Alta/Peak prefix. In December, Altazemini ranked #2; now it ranks #6 (–16 NVI). Altazingler has fallen from #7 to #21 (–32 NVI). Peak Fugleman MW suffered the worst proven drop: from #10 to #56, losing –44 NVI.
- Proven-genomic gap: The top proven NVI is +364; the top genomic NVI is +468—a 104-point gap at #1. Proven rankings carry higher reliability (67–83%) and correspondingly less re-ranking risk.

December’s #2 and #3 both fell significantly: Altazemini dropped within the current top 10 (–16 NVI), while Kax Gladius Gazebo (–29) slid to #13 and All Nure Wendat (–23) to #14. Only Badger Ssi Ahead, December’s #1, held firm. Delta Reloader Finder, the sole 95% Rel bull in December’s top 10, dropped from #8 to #20 (–24 NVI)—proof that even high reliability doesn’t guarantee stability when the trait profile doesn’t match what the index rewards. The proven list saw 50% churn overall: 5 returnees and 5 new entrants—a much more volatile reshuffle than the genomic B&W list’s 10%.

| 10 | Cardiff P-Red PO | +378 | +362 | 3 | +16 | 482 | 1240 | GGI | 70% |
- Complete reshuffling: 6 of 10 are new entrants—all six carry the CRV Delta prefix. Only 4 return from December’s top 10. That 60% turnover is a stark contrast to the B&W genomic list’s 10% churn.
- December’s #1 slides: Ell Schach Skat (GGI) was R&W #1, with +382 NVI. He gained +18 to +400 in April 2026, but dropped to #7 as the CRV wave pushed past. December’s #2, Brakels Elevate Rammstein (Kam), fell to #12 (+373 NVI, April 2026).
- CRV concentration is extreme: 6 of 10 are CRV bulls, all Delta prefix. For R&W programs, sourcing outside CRV means choosing from a very short list.
- Delta Pronto P-Red gained the most among returnees: +54 NVI (+351→+405, April 2026). Delta Flagship P-Red gained +39 NVI but carries a conspicuously low INET of 237—the lowest in the R&W top 10 by a wide margin. His NVI rank is built almost entirely on functional traits.
- The R&W-B&W gap is closing. The R&W #1 at +454 NVI approaches the B&W genomic top 3. Delta Richman’s INET of 740 is competitive with B&W genomic leaders.
Where the Indexes Agree — and Where They Don’t
The genomic, proven, and R&W lists rank different populations, so direct cross-list comparison isn’t possible. But within each list, the tension between NVI ranking and sub-index profiles reveals where breeding philosophies diverge.
Consensus Pattern
Across all three lists, bulls combining moderate-to-strong INET with above-average Lvd dominate the NVI top 3. Rise Up Real (INET 614, Lvd 1084), Bento (INET 673, Lvd 1109), and Sunrise Superfly Rio (INET 702, Lvd 867) all achieve NVI leadership without extreme production or extreme longevity—they sit in the upper-middle range of both.
Rank-Divergent Sires
| Bull | NVI Rank | INET | Lvd | Divergence Signal |
| Genosource Mystro (B&W Gen) | 6 | 881 | 751 | Highest INET in B&W Gen top 10, lowest Lvd band. Pure production play. |
| Halifax Delta Dawn (B&W Gen) | 5 | 801 | 825 | Second-highest INET, below-median Lvd. Revenue-per-lactation sire. |
| Genosource Benson (B&W Gen) | 8 | 719 | 1251 | Highest Lvd in B&W Gen top 10 by 142 pts. Longevity outlier. |
| Peak Breaking News (B&W Prov) | 5 | 310 | 854 | Lowest INET in proven top 10 by a wide margin. NVI rank entirely from functional traits. |
| Delta Flagship P-Red (R&W Gen) | 9 | 237 | 754 | Lowest INET in R&W top 10 (by 203 pts). Health-fertility specialist. |
The Core Tension This Run
NVI’s functional-trait weighting continues to reward bulls whose production credentials alone wouldn’t crack the top 20 on INET. Peak Breaking News at proven NVI #5 with an INET of just 310, and Delta Flagship P-Red at R&W NVI #9 with an INET of 237, are the starkest examples. Meanwhile, Genosource Mystro’s INET of 881 earns him only NVI #6 because his Lvd of 751 drags his total-merit score. The practical question for breeders: if your herd’s economics are driven primarily by milk revenue per lactation, NVI’s top 10 overweights longevity and health relative to your cashflow reality. If your economics depend on cow survival and replacement costs, NVI’s weighting aligns well with your situation.
How to Use These Sires This Season
Cross-Index Leaders
For herds wanting a single-sire shortlist that balances production, health, and longevity without extreme trade-offs: Rise Up Real (+468 NVI, INET 614, Lvd 1084, April 2026) and Bento (+450 NVI, INET 673, Lvd 1109, April 2026) occupy this space. Both held top-10 status across two consecutive runs—Rise Up Real at #3→#1, Bento at #7→#2. For herds prioritizing overall genetic gain with moderate risk tolerance, these are the lead candidates.
High-Reliability Anchors
If daughter-proven confidence matters more than genomic ceiling: Badger Ssi Ahead (+364 NVI, 81% Rel, April 2026) and Genosource Captain (+363 NVI, 83% Rel, April 2026) are the proven leaders. Genosource Captain’s +74-point gain suggests his genomic prediction was conservative—his daughters are outperforming expectations. If your conception rate or semen budget demands fewer, higher-confidence matings, these two reduce re-ranking risk substantially.
Production-First Sires
High-input herds chasing revenue per lactation should consider Genosource Mystro (INET 881, NVI #6, April 2026) and Halifax Delta Dawn (INET 801, NVI #5, April 2026), which have the strongest production profiles in the genomic top 10. The trade-off is explicit—Mystro’s Lvd of 751 and Halifax’s Lvd of 825 are both below the top-10 median of 1031. If your herd manages longevity through management rather than genetics, these bulls deliver more revenue per daughter per lactation.
Longevity and Functional-Trait Specialists
Grazing, robotic, or low-input systems where cow survival and health costs dominate the P&L should consider Genosource Benson (Lvd 1251, NVI #8, April 2026), who carries an extraordinary longevity prediction. Chanello(Lvd 1106, NVI #9, April 2026) offers a non-CRV alternative with similar Lvd strength. Be cautious—Benson’s Lvd is the highest in the entire top 10 by 142 points, which at 70% reliability could compress significantly on re-evaluation.
R&W Outcross Options
R&W breeders facing CRV saturation (6 of 10 R&W genomic sires are CRV Delta) have limited non-CRV options: Ell Schach Skat (GGI, +400 NVI, Lvd 1092, April 2026), Cardiff P-Red (GGI, +378 NVI, Lvd 1240, April 2026), Poppe Freelance Cr (Kam, +405 NVI, April 2026), and Hlb Crawford Cr (Indep, +392 NVI, April 2026) are the only non-CRV options in the R&W top 10.
30-Day Action
Pull your current mating list and audit sire-line overlap. If more than 30% of planned matings trace to CRV Genosource or CRV Delta bulls, you have a concentration risk that this run’s data makes visible. Cross-check whether Delta Time Jump P—the sole B&W Genomic top-10 dropout (Dec #5, now ~#13 at +403 NVI, April 2026)—is still in active rotation and re-evaluate its allocation. On the proven side, review whether Peak Fugleman MW (Dec proven #10, now #56 at +243 NVI, April 2026) or Peak Altazingler (Dec proven #7, now #21 at +271 NVI, April 2026) are still allocated at December-level semen volumes.
Key Takeaways:
- The entire B&W genomic top 10 inflated — but not equally. Rise Up Real and Bento each gained +58 NVI to claim #1 and #2; Halifax Delta Dawn gained +19 and dropped three spots. In this run, anything below +30 meant losing ground even if your bull’s numbers went up.
- NVI is rewarding longevity over production, hard. Rise Up Real leads at +468 NVI with an INET of just 614 — carried by Lvd 1084. Genosource Mystro’s INET of 881, the highest in the top 10, only buys him #6. If your herd economics are lactation-revenue-driven, NVI’s ranking order doesn’t match your cashflow reality.
- Genosource Captain is the proven story of the run. A +74 NVI jump on daughter data — from #9 to #2 at 83% reliability. His cows outperformed his genomic prediction by a wide margin. At that reliability, this isn’t noise.
- CRV concentration demands a mating-list audit. Five of ten B&W genomic slots, six of ten R&W genomic slots — all Delta prefix in the reds. If more than 30% of your planned matings trace back to CRV lines, this run just made that risk visible. Pull the list before your next order.
- December’s proven picks are bleeding out. Peak Fugleman MW dropped from #10 to #56 (–44 NVI). Peak Altazingler fell from #7 to #21 (–32 NVI). If either bull is still in your tank at December allocation levels, you’re paying for rankings that no longer exist.
