The latest Holstein rankings are no exception as they continue to be headed by leading US sire O Bee Manfred Justice, now on a ￡PLI of 95. Justice still ranks number one in the US and is also one of the top rated bulls in the states for Productive Life. On this side of the Atlantic the bull is one of only three over 60kg CFP and he combines this with a good SCC PTA of -13%and calving ease.
