August 2020 – Holstein Canada Genetic Evaluations

August 2020 – Holstein Canada Genetic Evaluations

The Covid‐19 pandemic resulted in some degree of service interruption and modification for both milk recording and type classification starting March 2020. This reality affected the volume of data available for genetic evaluations, which reduced the number of newly proven sires this
round, and also increased the interval between test days and classifications for some cows in
herds across the country. As a consequence of these unprecedented circumstances, Lactanet
Canada has temporarily relaxed the criteria for affected cows to receive official production
indexes and therefore official LPI and Pro$ values.

See the Summary Table for the August Evaluation HERE!

“Lambda” is the Sole Newcomer to Penetrate Top 10 for Both LPI and Pro$
Farnear Delta‐Lambda‐ET (Delta x Numero Uno) takes centre stage as the only newly proven sire this round that achieves Top 10 status for both indexes. For LPI, Lambda grabs #2 spot, behind Peak AltaMarlon (AltaSpring x O‐Style), who holds on to the leader position as #1 LPI sire, and both bulls now share #6 position for Pro$. EDG Rubicon‐ET (Mogul x Robust) remains the breed leader for Pro$ and Fat but loses some ground for LPI taking #5 position this round. S‐S‐I Millington Totem‐ET (Millington x Jacey) also remains very strong for both indexes, staying in #3 LPI position and climbing to #2 Pro$. Although S‐S‐I Kingpin Phantom‐ET (Kingpin x Supersire) experiences some slippage, he maintains Top 10 status for both indexes at #3 Pro$ and #10 LPI (tied #7 Fat, tied #5 Protein). The sixth and final bull that ranks among the Top 10 for both indexes this round is Ronelee Midnight Detour‐ET (Midnight x Mogul), who is now at #5 Pro$ while climbing the LPI ladder to grab #7 position.

Three other newly proven sires achieve Top 10 status for either LPI or Pro$. The highest of these
is Westcoast Guarantee, who is the first proven son of Boastful in Canada (dam is IHG Tango
Gafney‐ET) that lands at #4 Pro$ (#58 LPI). S‐S‐I Silver Spike‐ET (Silver x Jacey) also penetrates the Top 10 Pro$ list with his debut at #8 Pro$ (tied #21 LPI). On the LPI list, its Kings‐Ransom H Download‐ET that arrives in #8 position (#26 Pro$), who is the highest of the first three sons of Hotshot now proven in Canada (dam is Kings‐Ransom Doorm Diva‐ET).

For LPI, three previous Top 10 sires maintain this elite status this round, including Stantons
Alligator‐ET (Kingboy son out of Stantons McCutchen 1174 Agree) at #4 LPI (#82 Pro$, #3
Conformation), Westcoast Randall (Loptimum x Numero Uno) at #6 LPI (#13 Pro$), and Holyland Elite Exactly‐ET (Halogen x Mixer) at #9 LPI (#37 Pro$). The same is true for Pro$ as two previous Top 10 sires maintain this status as Peak Hotline‐ET takes #9 Pro$ (#17 LPI, tied #7 Fat) and EDG AltaYura (Cashcoin x Robust) completes the list at #10 Pro$ (#140 LPI, tied #7 Protein).

In addition to the four newly proven sires already mentioned that achieve Top 10 status for at
least one index, there’s another group of six newcomers that make their debut this round
achieving Top 30 status. Three of these bulls achieve this ranking for both LPI and Pro$, namely
Peak AltaAmulet‐ET (first proven son of Josuper in Canada, dam is OCD Mogul Abracadabra‐ET) at #18 Pro$ and #19 LPI, S‐S‐I Silver Sonic‐ET (Silver x Multiply) at #12 Pro$ and #24 LPI, and Peak AltaMantra‐ET (Wickham x Supersire) at #20 Pro$ and tied at #29 LPI (tied #9 Fat).

For LPI, the two bulls arriving among the Top 30 list with their first official proof are Vekis DG Lockheed‐ET (AltaSpring x Meridian), who grabs #16 LPI spot (#36 Pro$), and is closely followed by Stantons Galore‐ET (Silver son out of Stantons Crazy 4 Camaro‐ET) at #18 LPI (#31 Pro$). On the Pro$ list, its Claynook C‐Suite (AltaSpring son out of Claynook Colita Bombero, full brother to Claynook Country proven in the US) that achieves Top 30 status with his arrival in #29 Pro$ position (#64 LPI).

Top GLPI and Pro$ Cow Lists Both Have a New Leader
The highest newly indexed cow this round for both indexes is Benner Salvatore Jamocha as she
reaches the #1 GLPI summit and also grabs #6 Pro$ position. This outstanding debut means that Jamocha surpasses her dam, Benner Octoberfest Jingko, who maintains her Top 10 status on both lists at #4 GLPI and #5 Pro$ (#10 Milk). On the Pro$ side, its Stantons Guarantee Go For Gold (dam is Stantons Bee Desired‐ET) that climbs the list from #8 position to now take #1 Pro$ honours (tied #60 GLPI, tied #4 Protein). The former breed leader for both indexes, Midas‐Touch Hot Holy‐ET (dam is AOT Rubicon Happening‐ET), loses some ground but now ranks #3 for both GLPI and Pro$ (#5 Fat). The other cow that manages a Top 10 ranking for both lists is Stantons Hot Dollars‐ET (Helix daughter out of Stantons Real Dollars‐ET) at #2 Pro$ and #7 for GLPI (tied #8 Fat). Three other Helix daughters with the Stantons prefix also excel for Pro$ this round, namely Stantons Some Helix‐ET at #4 Pro$ (#36 GLPI, #4 Fat, dam is Stantons Bee Something‐ET), Stantons Dollar Helix‐ET at #8 Pro$ (tied #20 GLPI, full sister to Hot Dollars), and Stantons Helix Roll‐ET at #9 Pro$ (#19 GLPI, #1 Fat, dam is Stantons Just Rolling‐ET). To complete the Top 10 Pro$ list this round, Progenesis Detour Kansas stays firm in #7 position (#15 GLPI) while Progenesis Guarantee Mallow lands at #10 Pro$ (tied #77 GLPI).

Moving up the GLPI list this round to take #2 position is Lindenright Lambda Mocha (#16 Pro$), who is a daughter of the highest newly proven sire, Lambda, out of Lindenright Rubicon Moofia. Three newly indexed cows this round also manage to penetrate the Top 10 GLPI list, namely Progenesis Imax Perfection at #5 GLPI (#19 Pro$, dam is Synergy Rubicon Perfect‐ET), Benner Salvatore Jamboree at #6 GLPI (#11 Pro$, full sister to Jamocha), and Nemesis Zipit Laius at #8 GLPI (#22 Pro$, dam is Dudoc Votto Lacune). The Top 10 GLPI list is completed this round with Stantons Adorable Approved at #9 GLPI (#101 Pro$, dam is Stantons Delta Approved‐ET) and Claynook May Randall in #10 GLPI spot (tied #61 Pro$, dam is Claynook Moxy Silver).

Two other newly indexed cows make an impressive debut by becoming trait leaders among cows
qualifying for the GLPI list, namely Siemers Jedi S‐Roz‐An‐ET (dam is Siemers Ltomx S‐Roz‐An‐ET) who is the new #1 for Milk at +3355 kg, and Blondin Jordy Darla*RW (dam is Hahncrest ATW Danica‐ET*RDC), who is the top cow for Conformation at +18.
