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.
