German-bred Laudan rises to 2nd in the rankings with a PLI of £214 and shows all round strength with milk production of 586kg and a Type Merit of 2.5. Like Leif, who is ranked 5th, Laudan now has a UK proof to back his extensive global standing.

Zenjo, who is bred from Durham son Zenith, enters the new rankings with a PLI of £167 and again meets’s stringent minimum standards criteria with milk production of 428kg and a Type Merit of 1.8.

Of many other significant performers from the stud, the American sire Classic Merrill Lynch from CRI stands out for his outstanding fertility index of +7, which is derived from a global proof based on a phenomenal 42,772 daughters in 9,394 herds. now has 15 bulls in the top 50 ranked by UK £PLI, more than double the number of any other semen company, and claims the best value for money genetics in terms of PLI points per £ spent.
