I am going to have the calf tested. If she is infected would that infect my bull or other cows ?

Saw calf nurse a couple of times on a test that wasn’t swollen. The next day that teat was also engorged.

Can you accurately test a cow for BVD if at some point in her life she was vaccinated for BVD?

There are 2 situations you talking about there.

For a normal healthy cow that may have been exposed to a high risk of exposure to BVD antibody levels would be measured and this will only be a guide. BVD in a healthy cow will only be a transient infection, you will not even realise she has been sick. If antibodies were measured early in the infection they would be normal they only increase as she recovers which she will do to a perfectly normal healthy and safe cow. Yes vaccination with a live vaccine will produce high antibody levels as well so will stuff up the results. This test is best done on a sample of cows to get an idea of the prevalence of BVD in a herd.

The 2nd situation is if that healthy cow just happened to be at a particular stage of gestation around the 100days from memory and if that calf is not aborted then when born will be a persistant shedder of the virus for the rest of its life and it is these that can be accurately identified with a skin notch test for virus antigen. The only exception would be if the ear notch test was done on the healthy cow above while she had the transient infection or freshly vaccinated with live virus, in this case a 2nd ear notch done a month or two later should the be -ve.

You can get a 3rd situation where a calf is infected in utero a bit later in gestation but its immune system is able to overcome the virus but it will be born weak, stunted and some defects but won't show up on an ear notch test.

Calf seemed weak and had sucken blueish eyes. Today the calf died , 2nd day. I am unsure if I should sell her? Give her antibiotics and re breed her? Also noticed her teats were large. I have included pics. Any advice ?

Large spiggots to me means that the calve died of mal-nutrition both during the embrio stage and after delivery as it couldn't suckle properly. They also signal me as an old cow, no way 4 years old, well past her prime.

The mail nutrition wasn’t from me. I have unlimited hay.

With a few exceptions, bred sale barn cows and especially young ones are there for a reason. Unacceptably large teats isn't necessarily a tell tale sign of advanced age but it most certainly gets worse as time goes by. That aside, I'd wager she likely lost her previous calf for that reason and consequently was shipped. FWIW, teats like hers are easy to spot on dry udders. Mouthing and/or reading the bangs tattoo will assist in aging cows with unknown history.

New born calves don't eat hay.

And unlimited hay does not mean it is quality. You can have all the hay in the world, but if it is not good, cows can starve on it.

greatgert - just what I was going to say.
I know a lot of you guys buy & sell from sale barn, but buying a skinny cow close to calving is a problem waiting to happen IMHO.
Jan - I know you have calves in and out of your farm, but for the general beef farm, bringing in a foster calf can be disastrous. Calf can be healthy, but be exposed to lots of bugs your own herd is not immune to potentially making all YOUR OWN calves get sick.
