Do you know where I can get the nutritional requirements for monitor lizards?
Point is...If you do not know the exact daily nutritional requirements of the monitor, what does the nutritional value of the feeder matter?
If you feed hissing roaches and have successful animals, I would not be too concerned over the specifics.
Also in the nutrition tables, you have to factor in the diets that the feeders are fed.....which accounts for the majority of their nutritional value.
Here is one nutition table for insects; however, it does not have hissing roaches on it.
