Do you know the facts on infertility diseases in beef cattle? Protecting your cattle against infertility diseases can be expensive but reproductive losses and associated veterinary bills can be even more costly to your enterprise.

This fact sheet covers reproductive losses associated with infertility diseases in beef cattle and how to prevent this occurring in your herd.

The items covered in this article were:

• Common reproductive losses

• Abortion caused by non-infectious diseases

• Abortion caused by infectious diseases

• How to identify the cause of any reproductive losses

• How you can protect your cattle

Key points were as follows:

• Reproductive diseases in cattle are common.

• Non-infectious causes of abortion account for about 7% of losses in cattle (of those abortions investigated in NSW Department of Primary Industries laboratories, some are due to non-infectious factors, such as dystocia (difficult birth) (6%) and genetic diseases (about1%).

• Infectious causes of reproductive losses include bovine campylobacteriosis (vibriosis), leptospirosis, pestivirus (bovine viral diarrhea virus, mucosal disease), neosporosis, trichomoniasis, akabane, aino and palyam viruses, septic abortion, and fever.

• When a producer faces reproductive losses, it’s important to identify the cause. Elements to consider are calving patterns, patterns of empty cows, blood tests or post-mortem examination of dead or aborted calves (Always wear protective gloves when picking up a fetus or placenta (to avoid the possibility of catching leptospirosis and Q fever); place it in plastic bags and refrigerate it).

• Know what steps to take to protect your herd from infertility causing infectious diseases. Important things to consider are culling dry cows, implement a vaccination program, pregnancy tests your herd and maintain records.
