Use this page to benchmark herds, cows and dairy sires, and check out how the genetic merit of the national herd is trending over time.

BW (Breeding Worth): This index indicates the expected ability of a cow or bull to breed replacements which are efficient converters of feed into profit.

PW (Production Worth): This index indicates the ability of a cow to convert feed into profit over her lifetime. PW includes factors like hybrid vigour, which cannot be passed on to progeny.  

Reliability: BW and PW are reported with an associated reliability. This a percentage figure and gives an indication of how likely a BW or PW is to change as new data is added. For example, a BW of 150/99 should be stable, where a BW of 150/35 is highly likely to change.
