How do I supplement baby tortoises when your instructions say 'give 1 pinch per kg of animal'.
Tortoises walk through their dinner and take the Nutrobal with them some days, others they simply miss it, others they take the lot. Nature is wonderful at achieving balance out of whatever we throw at it. Even the small tortoise isn't a problem because a tiny/small pinch is fine, we always feed to excess so Nutrobal and food are left behind.
As part of answering the question, we need to look at how tortoises are fed, and how they eat. In general more food is given than they eat, they then walk through it munching on what takes their fancy, so some powder is missed, stuck to the head, carapace or simply left on the ground. Care needs to be taken with feeding hatchlings as they are 'programmed' to eat as much as is available to allow for the days when food isn't around. This can mean that they overeat generally if given ad-lib food, this will cause a rapid abnormal growth rate and often leads to lumpy shell etc. One answer is to feed just once aday with high fibre, weedy plant material, do NOT overfeed.
So for supplementing small tortoises just use knife-point type amounts of Nutrobal to sprinkle on food and give it on alternate days, on the other days use Calci-Dust sprinkled on the food. The other way of doing it is just to have in mind the term 'lightly dusted'.
