I had a filly whose dam's milk didn't come in. Initially the vet tubed her some colostrum then the next day he did the IgG test. It was low so he did a plasma transfusion. The next day he did another IgG and it was good so she didn't need any more plasma. He gave the foal an N-G tube and I had to ''feed" her thru it every 2 hours round the clock. I kept her with her dam and eventually, after about the 3rd or 4th day, the mare's milk came in and the foal did fine. I never bred that mare again. I was afraid to.Those who have had foals that needed plasma transfers, did your vet transfer more than once? Did you have multiple IgG's done and if so when?
