Canadian Holstein Highlights – August 2020

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

“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 thatachieves Top 10 status for both indexes. For LPI, Lambda grabs #2 spot, behind Peak AltaMarlon (AltaSpring xO‐Style), who holds on to the leader position as #1 LPI sire, and both bulls now share #6 position for Pro$. EDGRubicon‐ET (Mogul x Robust) remains the breed leader for Pro$ 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 bothindexes, staying in #3 LPI position and climbing to #2 Pro$. Although S‐S‐I Kingpin Phantom‐ET (Kingpin xSupersire) experiences some slippage, he maintains Top 10 status for both indexes at #3 Pro$ 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 isRonelee 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$. The highest of these is WestcoastGuarantee, who is the first proven son of Boastful in Canada (dam is IHG Tango Gafney‐ET) that lands at #4 Pro$(#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 thehighest of the first three sons of Hotshot now proven in Canada (dam is Kings‐Ransom Doorm Diva‐ET).

The same is true for Pro$ as two previous Top 10 sires maintain this status as Peak Hotline‐ETtakes #9 Pro$ (#17 LPI, tied #7 Fat) and EDG AltaYura (Cashcoin x Robust) completes the list at #10 Pro$ (#140LPI, 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.

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) thatachieves 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 #1GLPI summit and also grabs #6 Pro$ position.
