Loek van de Graashook combines two bulls of the highest calibre. Loek was sired by no one less than Lucas van Boszicht. For many years Lucas had a reputation as the ultimate sire for good calving ease with muscular calves that grew well. A calf by Lucas generally had something extra to offer. Dorus van de Plashoeve produced lightweight, good calves. He was so immensely popular that the entire stock of his straws almost sold out within a week of his death.
In other words, two real star performers combined in the maternal line of Bobo, Shaun and Dino, who are all showing great results. Bobo belongs to the category of bulls that give the greatest maternal calving ease. Loek scores 4 out of 5 stars for calving ease.
