Spontaneous tumours 46% testes,16% adrenal, 5% pituitary, 6% skin and ear duct and fewer of other types in males; 21% pituitary, 13% uterus, 11% mammary gland, 6% adrenal and fewer of other types in females. Other conditions include 28% of males and 20% of females with absent, hypoplastic or cystic kidneys on one side sometimes associated with an absent or defective uterine horn or atrophic testes on the same side (Maekawa and Odashima 1975). These abnormalities have a polygenic mode of inheritance (Cramer and Gill 1975).
Breeding Conditions
Usually good breeding performance but reduce litter size in case of females with agenesis of the uterine horn.
