Thanks, Desiree
The IgG probably every farm should do. It costs us $55 + the farm call. They also examine the baby and the mare, and check the placenta which is good if you're not confident of how to check it to be sure none was retained, etc.
The plasma is $290 a bag that does a full size horse foal. A mini only gets maybe 1/4-1/3 of it max. It's only good though for 24 hours so the rest of the bag is thrown away. I think it's another $50 or so for the vet administering it (IV and it takes about 45 minutes or so). The practice is looking into getting mini size bags of it which would be a nice savings if they can get it that way.
The IgG is a good routine measure. The plasma may honestly be above and beyond for the average person to feel they should worry about but given that we had sick horses and how much I love the babies, I just didn't want to take any chances and this was what my vet practice recommended as the silver bullet for all things that I worry over
With Piper, we had a snow storm looming the day after she was born so I actually opted to do the plasma earlier than 12hours old (as the roads were going to be getting bad). So we didn't do the IgG until the next day. It would likely have been too early at the time she got the plasma (may have gotten a weak result only because it hadn't been at least 12 hours from when she first nursed). So, this one ended up being more expensive with the two farm calls but given the weather, it seemed the best bet to be sure she got all she needed. With the two farm calls, horse exams, etc., I think it was like $600 for all including farm calls, IgG, plamsa...
Last year when Passion was born, she had a rocky start (was full term but looked dismature). She did NOT get enough colostrum from her dam, so we HAD to have her transfused. She actually got two transfusions and she's healthy as they come now as a yearling. But, had we not known to get the IgG which showed us she didn't get enough colustrom, then we could have lost her on down the road before weaning when she could have succumbed to illness she had no protection against (had she not been transfused).
