SUMMARY Some factors influencing the causation of stillbirths in cattle were studied in 105,122 progeny of 100 bulls of eight breeds over a period of 8 years. The breed of dam was not considered. The calves of Friesian bulls were studied in greater detail than those of seven other breeds, in view of the greater numbers available.
