The Pro$ formula was updated in April 2020 to ensure the index remains current with the latest changes to milk pricing and costs of production in Canada. The most visible change with the Pro$ update is that Pro$ values for top animals in the Holstein and Jersey breeds increased notably. The range of observed Pro$ values has broadened with top animals increasing the most and the lowest ranking bulls decreasing to be further below breed average. The current economic values used to derive the Pro$ formula produced higher and more variable cow lifetime profitability values when applied to actual data compared to the previous economic values. Sire Pro$ values directly represent the average difference in profit that their daughters are expected to earn up to the age of six years. Thus, the disproportionate increase in Pro$ values for top sires is explained by the greater average profits expected to be earned by their daughters.
