[Involvement of the creatine kinase test in the selection scheme of pig breeding programs]

With the increase of meat-quantity in the German pig-breeds in the sixties and seventies, more and more deficiency in meat-quality and stress appeared. It is based on a latent exertional myopathy. A result is an increase of Creatin-Kinase in the blood-plasma. It can be investigated by an analysis in a laboratory. The results from this analysis supplies us with information about the susceptibility to stress of the investigated pig. This physiological proceeding is consistently used in the CK-test to select stress-stable pigs. In HULSENBERG this test is used since the end of the seventies with great success.
