Never hesitant to “reach back” in the semen tank and use bulls from yesterday that have proven themselves, JDH Sir Whitman is a result of continuing to utilize tried and true genetics. Sired by the Dwayne (Prescott x 204/2) bull and out of a cow who contains some of the most maternally superior genetics we have, not only is 999/4 the right shape and type to get the job done but his genotype should aid him in producing outstanding females.
