Farmscape for November 30, 2021

The Manager of the Canada West Swine Health Intelligence Network is encouraging pork producers to submit samples for diagnostic analysis when they notice signs of reproductive syndrome, typically abortions.
Earlier this month the Canada West Swine Health Intelligence Network released its Swine Health Surveillance Report for the third quarter of 2021.
One of the issues raised by veterinarians participating in the quarterly conference call was reproductive syndrome or abortions.
CWSHIN Manager Dr. Jette Christensen notes abortions are one of the early signs of African Swine Fever and are eligible for ASF rule out testing under CanSpotASF.

Clip-Dr. Jette Christensen-Canada West Swine Health Intelligence Network:
The causes of abortions are really really complex.
There can be many many issues that go into that.
It could be management, it could be stress, it could be feeding, but this time we discussed that apparently over the last couple of quarters we've seen, at the laboratories, a lower proportion of submissions came up with an organism.
The reason for that is you should definitely keep sending materials from abortions to the laboratories because what they can do is either confirm that there's an infectious agent or organism that causes the abortion.
That could be for instance PRRS or it can rule out that there are specific organisms that cause the abortions and then you have to go to the management factors to figure out what is going on in abortions.

Dr. Christensen suggests a laboratory diagnostic analysis will indicate whether the abortions are the result of a specific organism or are the result of a management issue.
She says it will also provide peace of mind by demonstrating that the cause is not African Swine Fever.
