The Pro$ ceiling dropped ~250 points for most top bulls. If your sire lineup hasn’t changed since December, your income math has.
Executive Summary: ROZLINE just lost 626 Canada Pro$ in one run (from +2664 in December 2025 to +2038 in April 2026), while PARFECT quietly gained 58 Canada LPI points to take #1 at +3914. PATTERN stays #1 on Canada Pro$ at +2974 but gives back 237 Pro$, and CABO trims 231 Pro$ to sit at +2877, which means the Pro$ ceiling on proven sires dropped ~200–250 points for most front‑end bulls. That’s a different risk picture if you’re budgeting semen off last run’s income numbers or counting on single‑bull exposure to carry your Pro$ average. The daughter‑proven LPI and Pro$ top 10s are still anchored by many of the same names, but the big Pro$ hits to ROZLINE and GRAZIANO and the new arrival of POWERSTAR at +2854 Pro$ show how quickly “go‑to” bulls can be repriced. Genomic GPA LPI and GPA Pro$ lists remain volatile, with new bulls rotating through the top 10, so stacking too many matings on a couple of young sires is still a higher‑beta play. If your herd prioritizes income, robot‑friendly type, or inbreeding control, this run gives you clear signals on which proven sires to keep as anchors, which to demote to niche roles, and where Red/polled or alternative‑family outcrosses can keep your milk cheque and future mating options safer.
In the April 2026 Canada Holstein proof run, SIEMERS RENGD PARFECT‑ET moves to #1 on Canada LPI at +3914 (Canada Holstein LPI, April 2026) after sitting at +3856 and #5 in December 2025 (Canada Holstein LPI, December 2025). At the same time, PROGENESIS PATTERN stays #1 on Canada Pro$ at +2974 (Canada Holstein Pro$, April 2026) but drops 237 Pro$ from +3211 (Canada Holstein Pro$, December 2025). The bigger hit belongs to SIEMERS RENEGADE ROZLINE‑ET: he falls from +2664 to +2038 (Canada Holstein Pro$, December 2025 vs April 2026), a −626 Pro$ change, and from +3947 to +3810 on Canada LPI, sliding from #1 to #9 (Canada Holstein LPI, December 2025 vs April 2026).
For elite breeders and AI programs, this April 2026 Canada Holstein run matters because it compresses the top of both Canada LPI and Pro$ rankings, trims the income ceiling on several headline bulls, and shifts which sires you should treat as portfolio anchors vs. specialists over the next 6–12 months. The daughter‑proven front edge looks more stable than the genomic lists, but the magnitude and pattern of Pro$ changes still carry real implications for how you weight income vs type at the very top.
What Changed at the Top?
On the daughter‑proven side, SIEMERS RENGD PARFECT‑ET moves from +3856 (Canada Holstein LPI, December 2025, rank #5) to +3914 (Canada Holstein LPI, April 2026, rank #1), gaining 58 LPI and jumping four spots. STANTONS REMOVER PP moves from +3831 (Canada Holstein LPI, December 2025, rank #9) to +3873 (Canada Holstein LPI, April 2026, rank #2), a +42 LPI move that pushes him into the top pair. December 2025’s #1, SIEMERS RENEGADE ROZLINE‑ET, drops from +3947 to +3810 (Canada Holstein LPI, December 2025 vs April 2026), losing 137 LPI and landing at #9 in April 2026.
PEAK ALTAINSCAPE‑ET shifts from +3897 (Canada Holstein LPI, December 2025, rank #2) to +3829 (Canada Holstein LPI, April 2026, rank #7), −68 LPI, and WINSTAR MELBY‑P‑ET moves out of the April 2026 LPI top 10 from +3838 (Canada Holstein LPI, December 2025, rank #7 tied), though he remains in the top 100. Overall, roughly seven of the December 2025 Canada Holstein LPI top 10 still sit in or immediately around the top 10 in April 2026, with 3–4 bulls rotating in and out.
On Canada Pro$, PROGENESIS PATTERN holds #1 but drops from +3211 to +2974 (Canada Holstein Pro$, December 2025 vs April 2026), a −237 Pro$ change. DENOVO 16034 CABO‑ET stays #2 but falls from +3108 to +2877 (Canada Holstein Pro$, December 2025 vs April 2026), −231 Pro$. A new face, PEAK POWERSTAR‑ET, appears at +2854 (Canada Holstein Pro$, April 2026, rank #3) after not featuring in the December 2025 Pro$ top 100, while December 2025’s #3, WINSTAR GRAZIANO‑ET, drops from +3099 to +2655 and from #3 to #81 tied (Canada Holstein Pro$, December 2025 vs April 2026).
The headline shift is clear: the LPI front is reshuffled but still anchored by broadly similar bulls, while the Pro$ ceiling has been lowered by roughly 200–250 points for most top‑end sires, with ROZLINE and GRAZIANO seeing much larger income hits.

- Trait profile (April 2026): +683 Milk, +125 Fat, +47 Protein, +1.33%F, +0.58%P, 0 Conf, HL 104, DCA 104.
- Role: still attractive where very high fat % and good management traits are prioritized; no longer a top‑band Pro$ pick for general use.
What Canada LPI and Pro$ Are Rewarding This Run
The April 2026 Canada Holstein LPI top group is rewarding production and components with strong, but not necessarily extreme, type. PARFECT at +3914 (Canada Holstein LPI, April 2026) shows +894 Milk, +85 Fat, +57 Protein, +0.39%F, +0.19%P, +10 Conf, MS +4, FL +15, DS +7 — a balanced yield and type profile. STANTONS REMOVER PP at +3873 (Canada Holstein LPI, April 2026) pushes more volume with +1793 Milk, +113 Fat, +81 Protein, +0.36%F, +0.23%P, +8 Conf, MS +5, FL +9. DUCKETT PFCT HAS IT ALL‑ET at +3843 (Canada Holstein LPI, April 2026) runs +2294 Milk, +52 Fat, +65 Protein, +0.30%F, +0.10%P, +15 Conf, MS +10, FL +10, DS +16, clearly prioritizing volume and show‑type.
On Canada Pro$, April 2026 favors bulls that convert fat and protein into net income with a solid, workmanlike type. PATTERN at +2974 (Canada Holstein Pro$, April 2026) sits at +1199 Milk, +106 Fat, +71 Protein, +0.47%F, +0.23%P, +3 Conf, HL 108, DCA 104. CABO at +2877 (Canada Holstein Pro$, April 2026) is +685 Milk, +117 Fat, +73 Protein, +0.56%F, +0.27%P, 0 Conf. POWERSTAR at +2854 (Canada Holstein Pro$, April 2026) combines +695 Milk, +109 Fat, +72 Protein, +0.55%F, +0.29%P, +4 Conf, HL 105, DCA 104.
Three contrasting case studies spell out the trade‑offs:
- PAZZLE (SIEMERS RZ PAZZLE 34954‑ET)
+3810 (Canada Holstein LPI, April 2026), +2038 (Canada Holstein Pro$, April 2026), +16 Conf.
+191 Milk, +145 Fat, +34 Protein, +1.16%F, +0.23%P, MS +5, FL +13, DS +16.
Trade‑off: extreme type and fat %, solid but mid‑band Pro$ — excellent for show‑leaning programs that still care about components. - DUCKETT PFCT HAS IT ALL‑ET
+3843 (Canada Holstein LPI, April 2026), +1960 (Canada Holstein Pro$, April 2026), +15 Conf.
+2294 Milk with moderate components and strong MS/FL — big‑volume, high‑type, mid‑Pro$.
Trade‑off: ideal for herds that monetize type and pedigree; less suited as a primary income sire. - PROGENESIS PATTERN
+2974 (Canada Holstein Pro$, April 2026), +3766 (Canada Holstein LPI, April 2026), +3 Conf.
+1199 Milk, +106 Fat, +71 Protein, strong health composite.
Trade‑off: less eye‑catching than the extreme type bulls, but a more efficient income engine for commercial‑style and large herds.
In short, April 2026 Canada LPI still pays strongly for type and functional conformation when coupled with components, while Canada Pro$ is unforgiving about the income math and will only carry high‑type bulls when their fat/protein profiles justify it.
Stud Power, Family Power, and Outcross Space
AI stud codes in the April 2026 Canada Holstein lists show a familiar pattern. Semex 200 code bulls (PROGENESIS PATTERN, PROGENESIS MONTREAL, PROGENESIS MONTEVERDI, PROGENESIS PRAGMATIC, and others) occupy multiple slots in both the LPI and Pro$ top 100 lists. Codes 0007, 0011, and 0029 (Select, Alta/Peak, and related groups) are also heavily represented: PEAK ALTAINSCAPE‑ET, PEAK ALTACRAZE‑ET, PEAK ALTAHOTHAND‑ET, PEAK POWERSTAR‑ET, and a large set of genomic BEYOND/SHEEPSTER and Rosemary‑line bulls lead the young‑sire lists.
Bloodline concentration is particularly evident in the top 100 genomic by GPA LPI and GPA Pro$. SIEMERS SSI ROSMRY TONKS‑ET leads GPA LPI at +4179 in April 2026 (Canada Holstein GPA LPI, April 2026), with several other Rosemary‑line sires close behind. On GPA Pro$, SIEMERS RIM COBOT‑ET at +3755 and KENYON‑HILL OLYOP‑ET at +3732 (Canada Holstein GPA Pro$, April 2026) again tie back into a handful of sire stacks.
Within the daughter‑proven lists, genuine outcross space still exists:
- DROUNER KL AUGUSTUS P RED at +3786 (Canada Holstein LPI, April 2026) and +2145 (Canada Holstein Pro$, April 2026) brings a Dutch Red, polled, alternative pedigree into the top 100.
- KOEPON OH ROBIN RED at +3576 (Canada Holstein LPI, April 2026) and +2302 (Canada Holstein Pro$, April 2026) offers another competitive Red option with different bloodlines from the main Renegade/Parfect and BEYOND/SHEEPSTER clusters.
For ET and AI programs heavily invested in Renegade/Parfect, BEYOND, and related families, these Red and polled proven bulls — plus a handful of non‑cluster foreign codes — are where the practical outcross opportunities live, even if they sit 1–2 index tiers below the absolute top of LPI or a couple hundred Pro$ points below PATTERN/CABO.
How Volatile Are Canada’s LPI and Pro$ Rankings Right Now?
Between December 2025 and April 2026, the daughter‑proven Canada Holstein LPI and Pro$ lists show more compression than chaos. Around seven of the December 2025 LPI top‑10 bulls remain in or near the top 10 in April 2026, and a similar proportion holds for Pro$, with PATTERN, CABO, REMOVER PP, ALTAHOTHAND‑ET, and others still occupying high ranks despite level changes. The top‑end Pro$ bulls mostly lose 200–250 points (PATTERN −237 Pro$, CABO −231 Pro$, ALTAINSCAPE −245 Pro$), while ROZLINE and GRAZIANO see much larger drops (−626 and −444 Pro$ respectively).
Reliabilities for these leading daughter‑proven sires are high and in the mid‑ to high‑90s for production and conformation in both runs, as shown in the official lists. For bulls like PATTERN, PARFECT, CABO, REMOVER PP, ALTAINSCAPE, and GRAZIANO, these shifts are less about sampling noise and more about model and economic rebalancing across traits. That’s important: a 200‑point Pro$ or 60‑point LPI change signals a reset in how the index values their trait mix, but it doesn’t make existing daughters suddenly “wrong.”
The genomic lists are more volatile. OCD MILAN‑ET at +4137 (Canada Holstein GPA LPI, December 2025) gives way to SIEMERS SSI ROSMRY TONKS‑ET at +4179 (Canada Holstein GPA LPI, April 2026), with several bulls rotating in and out of the top 10. On GPA Pro$, PEAK ALTAPURPOSE‑ET at +3947 (Canada Holstein GPA Pro$, December 2025) is replaced by SIEMERS RIM COBOT‑ET at +3755 and a different mix of bulls in the +3700–3800 band (Canada Holstein GPA Pro$, April 2026). With no or very few Canadian daughters behind these bulls, this volatility is precisely the risk premium you should expect from genomic evaluations.
For portfolio planning, treat the daughter‑proven LPI and Pro$ front edge as relatively stable anchors and the genomic lists as higher‑beta tools where you spread risk across several bulls rather than betting heavily on any single name.
What This Means for Your Matings This Season
This is the section where April 2026 turns into decisions.
High-Input, Housed, Income-Driven Herds
If your herd prioritizes net income per cow in high‑input, housed systems, your starting point is Canada Holstein Pro$.
- If your herd prioritizes maximum Pro$ with solid type, keep PROGENESIS PATTERN (+2974, Canada Holstein Pro$, April 2026) and DENOVO 16034 CABO‑ET (+2877, Canada Holstein Pro$, April 2026) as key anchors, and add PEAK POWERSTAR‑ET (+2854, Canada Holstein Pro$, April 2026) as a new proven income sire.
- If your herd already relies on bulls that lost >250 Pro$ — ROZLINE (−626), GRAZIANO (−444), REMOVER PP (−299), ALTAINSCAPE (−245) — keep using them, but narrow them to matings where their specific strengths (type, fat %, polled, or other traits) justify the reduced Pro$.
Within 30 days, pull your active service list and flag every bull that dropped more than 250 Canada Holstein Pro$ between December 2025 and April 2026; for each, decide whether he remains a mainline income sire or becomes a targeted, trait‑specific option.
Robot Herds and Udder/Feet Priority
If your herd is on robots or runs high milking frequency with tight udder/feet requirements, you’ll put more weight on Canada Holstein LPI and Conformation.
- If your herd prioritizes functional type with good components, look hard at PARFECT (+3914 LPI, +10 Conf, Canada Holstein LPI & Conformation, April 2026) and ALTAHOTHAND‑ET (+3853 LPI, +10 Conf, MS +7, FL +10, Canada Holstein LPI & Conformation, April 2026) as daughter‑proven anchors.
- If your herd wants type with enough Pro$ to keep the accountant calm, PAZZLE (+3810 LPI, +2038 Pro$, +16 Conf) and HAS IT ALL (+3843 LPI, +1960 Pro$, +15 Conf) give you show‑influenced cows that still rank decently on Pro$.
Be cautious using low‑Conf, low‑MS bulls as day‑to‑day sires in robot herds, even when they’re high on Pro$. PATTERN, CABO, and POWERSTAR are all safe on that front; some other high‑Pro$ bulls are not.
Type/Show-Focused Programs
If you live off classification sheets, sales, and show results, this run confirms that the Canada Holstein Conformation list is stable and well-stocked.
- If your herd prioritizes maximum Conformation, bulls like MATTENHOF HARRIS (+18 Conf, +278 Pro$, Canada Holstein Conformation & Pro$, April 2026), SWEETVIEW GRINCH P (+17 Conf), HAS IT ALL (+15 Conf), and PAZZLE (+16 Conf) remain prime options.
- If your herd wants show‑type without walking away from income, focus your main matings on bulls that pair high Conf with Pro$ north of +1900 — again, PAZZLE and HAS IT ALL are prime examples — and reserve lower‑Pro$ extreme type sires for donors and best cow families.
Avoid treating ROZLINE as a top‑end Pro$ sire after his drop to +2038 (Canada Holstein Pro$, April 2026); he now fits best as a type and components tool.
Inbreeding-Sensitive ET Programs and Outcross Management
If your ET work already stacks Renegade/Parfect, BEYOND, SHEEPSTER, and Rosemary‑line bulls, the April 2026 lists are a reminder that the top of Canada Holstein LPI, Pro$, GPA LPI, and GPA Pro$ is heavily concentrated around a few families.
- If your herd prioritizes inbreeding control, deliberately work bulls like DROUNER KL AUGUSTUS P RED (+3786 LPI, +2145 Pro$, Canada Holstein LPI & Pro$, April 2026) and KOEPON OH ROBIN RED (+3576 LPI, +2302 Pro$, Canada Holstein LPI & Pro$, April 2026) into donor matings as Red, alternative‑family outcrosses.
- If your ET program leans heavily on a handful of genomic GPA LPI or GPA Pro$ bulls sharing similar sires and grandsires, spread risk by adding slightly lower‑ranked genomic sires with less pedigree overlap, even if their GPA LPI or GPA Pro$ is 50–100 points lower.
Within 30 days, run a quick pedigree audit on your donors against your top five service sires; any donor‑sire combination that repeats the same 2–3 sires or grandsires on both sides should have at least one Red or alternative‑family option added to the mating plan.
Genomic-Heavy Portfolios (Studs and Large Herds)
If your program leans heavily on genomic bulls, the April 2026 Canada Holstein GPA LPI and GPA Pro$ lists highlight both opportunity and churn.
- If your herd prioritizes fast gain with controlled risk, you can use bulls like SIEMERS SSI ROSMRY TONKS‑ET (+4179, Canada Holstein GPA LPI, April 2026) or WELCOME GUSTAVSSON‑ET (+4064, Canada Holstein GPA LPI, April 2026) as sire‑of‑sons and key donor mates, but you should spread that exposure over multiple genomic bulls rather than anchoring on one.
- If your herd wants more stability, aim to keep at least 40–50% of matings on high‑reliability daughter‑proven anchors like PARFECT, PATTERN, CABO, REMOVER PP, and ALTAINSCAPE, and use genomic sires as the “top‑up” rather than the core.
A practical threshold: if more than 60–70% of your planned matings for the next proof interval are to bulls from the top 10 of the April 2026 GPA LPI or GPA Pro$ lists, you’re probably carrying more genomic volatility than necessary for the same level of genetic gain.
Key Takeaways:
- ROZLINE’s profile has flipped: he’s still +16 Conf and +3810 Canada LPI (April 2026) but lost 626 Canada Pro$ vs December 2025, so he’s now a type specialist, not a Pro$ anchor.
- PARFECT (+3914 Canada LPI, April 2026) and PATTERN (+2974 Canada Pro$, April 2026) are the key proven anchors, but both sit in a compressed top band where 40–60 LPI or 200–250 Pro$ moves can reshuffle ranks without changing cow‑side reality.
- GRAZIANO (−444 Canada Pro$) and several other December 2025 headliners took meaningful Pro$ trims, while POWERSTAR arrives at +2854 Canada Pro$ (April 2026), so any sire lineup built on last run’s income numbers needs a fresh audit.
- Genomic GPA LPI and GPA Pro$ tops are still churning, so herds with >60–70% of matings on a handful of young sires are running higher portfolio risk than the Canada Holstein daughter‑proven lists alone would suggest.
- For herds prioritizing income, robots, show type, or inbreeding control, this run clearly separates which bulls stay as everyday service sires (PATTERN, CABO, PARFECT, POWERSTAR) and which move to niche roles or outcross use (ROZLINE, PAZZLE, HAS IT ALL, AUGUSTUS P RED, ROBIN RED).

Methodology Note
This feature is based solely on the official Lactanet/Canadian Dairy Network Canada Holstein bull lists for December 2025 and April 2026: top 100 Holstein bulls by Canada LPI, top 100 Holstein bulls by Canada Pro$, top 100 Holstein bulls for Conformation, and the top 100 Holstein young bulls by Genomic Parent Average for LPI (GPA LPI) and Pro$ (GPA Pro$). All index values cited here are paired with the country (Canada), the index name (LPI, Pro$, Conformation, GPA LPI, GPA Pro$), and the proof run month/year (December 2025 or April 2026). Rank and index changes are only calculated for bulls appearing in both proof runs; new entrants and drop‑outs are described qualitatively without assigning missing values. No base change between December 2025 and April 2026 is indicated on these lists, so all comparisons are on a consistent Canada Holstein base. Genomic bulls (GPA LPI, GPA Pro$) are distinguished from daughter‑proven sires and should be treated as higher‑volatility tools within sire portfolios due to their lower effective reliability.
