Our Bulls


Rotokawa Cattle Company has developed an important new tool called a spider graph for evaluating and demonstrating the strengths and weaknesses of a bull or cow's body conformation. The conformation is a critical indicator of how well the animal will function for the producer. Ridge Shinn notes, "I first saw a graph of this type in France, used to illustrate progeny performance in sheep, and I applied the concept to evaluating cattle."

Rotokawa Devon 974

Bull 974 is the son of 667 who in turn was the son of the great Rotokawa 425. Bull 974 was the top bull in the Breed Plan measure of bulls in 2006. This frame 3 bull will add volume of meat to your calves and will put a rump on them. Bull 974 is no longer alive and therefore if you have plans to use this bull you should purchase and put aside some semen for the future. View this bull's pedigree.


Rotokawa Devon 667

Bull 667 is the son of Rotokawa 425, the bull that had a huge impact in England when he was introduced there. He ranked number 2 in the Breed Plan rankings in 2006. Bull 667 has a tremendous rump width percent and will add volume to any calves he sires. Bull 667 has a very positive impact on any cows with a questionable udder; we have seen him straighten out an udder in one generation. This is bull power. Bull 667 is no longer alive and supplies of semen are limited. View pedigree.
