The following secondary feeds are not suitable as the sole feed for Astrochelys radiata and should only be used occasionally in small rations, for variety, and in conjunction with the main premium feed.
Especially in the cold season, when fresh food from nature is scarce, a moderate use of secondary feeds is quite legitimate to bring some variety and color into the diet of Astrochelys radiata.
Always assuming that premium feed was consistently fed on the other days of the week, we feed in winter 1x per week a ration of endive or lettuce. To enhance the endive or lettuce ration, we mix it additionally with a product from the AGROBS "Teastudo" line (e.g. Testudo Fibre). We deliberately prefer endive or lettuce because these two varieties have a slightly more favorable calcium-phosphorus ratio than, for example, commercially available lettuce.
In the cold season we also feed 1x a month a mix of grated carrots, cuchetti, fennel, celery and cucumber. Ideally, these products should be previously juiced or squeezed by hand in grated state to avoid too much liquid. We also mix this mix additionally to enhance with a product from the line "Teastudo" of AGROBS (eg Testudo Herbs).
Maximum 4x a year we feed seasonally by hand small amounts of berries (eg blackberries, raspberries, strawberries, etc.) or a cactus fruit. These colorful treats are also excellent as an edible carrier for Panacur® Pet Paste for deworming because they are always eaten quite greedily, uncritically, due to the red color and enticing smell. Note that there are very few plants in the habitat of Astrochelys radiata that bear fruit seasonally (e.g. cacti). However, these fruiting bodies cannot be compared to commercial fruits in terms of content due to the dryness and soil conditions on which the plants grow. It is important to understand that fruits are in principle not an integral part of the diet of ray turtles and can cause serious health consequences if consumed regularly. Except for the secondary feeds listed above in the indicated rations, salads, vegetables and fruits should be avoided completely.
