Anyone else seeing issues with FV 32/40?

I don’t want to start a scandal if there’s a chance I’m wrong, but I’ve had 3 babies over and one opossum die when they were given FV 32/40. I’ve used it in the past with no problems. Is there a current issue with it? I was a GME user for the longest time as a vet, but when I got my rehab license many people recommended the switch to FV 32/40. I’ve never lost a baby to anything other than severe injury/sepsis in the past, and I’m crushed.

They were all appropriately warm, hydrated, gradually put onto diluted formula. A couple even received metoclopramide, simethicone, massage, SQ fluids, warm soaks, etc.

I switched to a new bag, same problem. I started two of them on GME then transitioned to FV because of the other rehabbers urging me to do so. I checked the boards for any recent FV recalls but didn’t find anything, so I went ahead.

Both were fine on GME but got cement gut and died after 24-48h on FV. They didn’t appear bloated, and they were eliminating. I performed necropsies on all 4–nothing notable except a curd of milk in the gut.

I have believed there was always a problem with FV 32/40 and therefore have never used it. I think there are some rehabbers who have been successfully using it but they don’t use it by itself. I think they are mixing it with Matrix Zoologic 33/40 and heavy whipping cream.

I think it’s best to keep them on goats milk formula and transition slowly to FV 20/50 around the 3 week point.

Hi Dan,

I am so sorry to hear about the loss of your babies. I am trying to think back when I was trying to switch over some pinky ratties to 32/40. I had the formula diluted to 50/50 and I watched the formula turn I ti cement in their gut as they died. I think it was 7 - 8 years ago. We talked about it on this board. The owner of fox valley has never acknowledged that there was/is a problem with 32/40. I would never use it again.

I start my babies on homemade goat milk formula and slowly switch over to FV 20/50 starting at 2.5 weeks until they are fully on it at 4 weeks.

Thanks so much—never again! So tragic. I don’t have any issues with any of the other FV formulations.
