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."
