[QUOTE="wbvs58, post: 1616630, member: 16453"] If you have a PI in your herd and they all co mingle then you won't have any issues when they breed as they will have natural immunity from having a transient infection. That is no issues except with the PI. Probably to get an idea whether you have BVD present is to get several of the healthy ones tested for antibodies to BVD. If they are all have a high titre then somewhere in your herd is a PI, don't despair antibodies are good, means they are immune. Note a PI won't have antibodies as they don't recognise the virus as being foreign. Once you know your status then you can start ear notching a couple to identify the PI. [/QUOTE]
