Do we know yet exactly what the immune deficit is in Blue Gouldians which makes them so vulnerable? I know that there are endless problems caused by cabinet breeding under Bengalese that would affect any bird negatively, but I mean beyond that. Because the better we understand it, the more likely we can design a workaround.
e.g. If the loss of red/yellow pigment in the feathers reflects a generalised failure to utilise carotenes properly, and therefore probably also a failure to convert beta carotene to vitamin A, this will result in quite extreme immune deficits, guarranteed. What do you think of this theory? Has anyone researched the exact mechanism?
If this is true, then it would make sense to try giving them pre-formed Vitamin A supplements instead of (or as well as) carotenes. Perhaps that would solve the problem?
Is there any research on this? What do we know so far?
