Last year, I switched from my normal regimen of RepCal calcium w/VitD and Herptivite to the T-Rex Sandfire Leopard Gecko Dust, and had ZERO fertile eggs for over 2 months until I switched back! This year is the first year I have used Vionate in my gutload, and I strongly suspect that is what's going on. It is the only thing I have done differently from previous years. The next time I change products/regimens, I am going to use a 'control' group and NOT switch all of my colonies at once!
Marcia, what's your current feeling on the use of Rep-cal with Vit D?
This year out of 14 hatches 2 have eyelid defects and one had to be euthanised because it lacked eyelids. Before last year, I hatched out virtually no deformities, and neither of the two deformities (minor tail kink, and spinal abnormality) had to be euthanised. Last year I blamed a temperature spike in my incubator, I still think that this accounted for a lot of my egg deaths but I'm now wondering if something else was going on that caused the eyelid defects.
Prior to last year (my first year with significant amounts of deformities), some inbreeding was going on in most of my breeding groups, crickets gutlaoded with crushed cat and dog food, fish flakes and assorted veggies were the staple, the crickets were dusted with rep-cal with vit D and herptivite at every feeding. In terms of incubators, for the first 3 years or so, the eggs were just incubated in a container in tank. The temperature fluctuations occurring in this set up seemed to pose no problem. Year 4 I got a hova-bator, but it was only used for males. Year 5 I got a second hova-bator for females.
Last year I switched to mealworms gutloaded with oats, bran, dog kibble, various cereals, and veggies. I cut back on herptivite, to about every couple of weeks. This year, I started out doing pretty much the same. After the first deformities, I started using herptivite at every feeding again. I also picked up some rep-cal without vitamin D3. I also broke up all the father daughter pairings.
Should I start using the rep-cal without vitamin D3 instead? I heard a public radio broadcast talking about vitamin D3. The said that the amount added in milk was almost insignificant when compared to how much was synthesized by the body after a few minutes in the sun. They also said that vitamin D3 was important enough that getting enough through sun exposure could out weigh the skin cancer risk. This got me thinking, if a leo were to emerge at dusk, would it start synthesizing D3, how much would they synthesize, how much do they need? I've been using it for a number of years now with no problems, should I change? All the groups producing the deformities are relatively new, so I don't think accumulation is an issue.
