Certainly infertility -- when hypovitaminosis A is a factor -- is a matter of the parents' diet (or some third factor that affects nutrient uptake, or the like). My untutored assumption is that SLS -- where hypo A is a factor -- is likely affected at least in part by the parents' diet in all frogs, and likely completely related to the parents' diet in the case of egg-feeders. I'd be very happy to be educated otherwise by the more experienced and knowledgable here.
I'm not sure that I personally would be likely to wait for signs of deficiency before supplementing. I exercise not after I have a heart attack, but rather to prevent one. It seems as if quite a few folks here routinely supplement A, so I ride that wagon.
That all makes sense. As for SLS, I am not all that sure why most people don't struggle with it anymore (see how infrequently it comes up on the board and it seems to be mostly a supplementation issue when it does come up). I looked it up a little bit and it looks like people have varying proposals for what it is that the turn-around can be attributed to. I am glad we are living in the time we are where SLS is not something I have ever had to deal with.
I should have clarified that I am not waiting until there is a problem to supplement more than just Calcium Plus. I supplement with Calcium Plus and add some Vit A (and some Superpig sometimes) to augment the Calcium Plus for all of my frogs (regardless of their breeding status). Even with that, however, I will still occasionally have a situation with either a) new frogs that I don't know have been supplemented correctly in the first place or b) frogs I have had for a while that I have not bred for whatever reason. These situations sometimes require different kinds of supplementation intervention depending on the situation. I am not "waiting for signs of deficiency" but that doesn't mean that they don't crop up periodically regardless of how I am supplementing. I guess the moral of the story is that you can't be slavishly devoted to any particular approach, especially if have reason to believe that what you are doing isn't working. I didn't mean to imply that I am only using Calcium Plus and hoping for the best :-)
