Feeding of Tortoises

Feeding European Tortoises

(by Dr. M. Baur and Prof. Dr. R. Hoffmann, Zoological Institute, Munich, Germany)

European and Central Asian Tortoises are very popular as pets. In the wild, they are extremely well adjusted to their original habitats. Therefore, their feeding requirements are also to be regarded as an adjustment to environmental conditions.
In the original habitats of European tortoises, a mild, during summer (from May on) and a dry Mediterranean or continental climate is prevailing. The animals have access to sufficient green plants - comparabel to the spring growth of a meagre central European meadow - only during springtime. From May on, the plants dry out increasingly and therefore contain distinctly less protein and easily digestible, highly energetic substances. The available nutrition is then partly comparabel to hay. In the steppe areas of central Asia, similar, however, even more extreme conditions prevail.
To exist in such habitats an to utilise the resources availabel there these species have developed particular anatomical structures and physiological adjustments. For example, they have a relativeley small stomach with a low extensibility so that they cannot consume large amount of food at once but have to take in many small rations distributed over the day. Caecum and Colon are enlarged adn form spatially highly extended fermentation chambers which fill a major part of the abdominal cavity. Within said chambers, crude fibre is decomposed by means of a controlled fermentation with the aid of an extremely efficient and diverse intestinal flora (various bacteria and protozoons) and made usable for the tortoise. For this purpose, the food remains in the digestive system for up to two weeks and forms a three-dimensional grid of crudes fibres therein, offering a large area of attack for nutrient absorption to the intestinal flora. However, if the structured crude fibres are missing or replaced by easily digestible substances (such as starch or saccharides), a faulty fermentation including an exteme decrease of the retention time of the food in the guts occur. The intestinal flora is partly displaced or dies off. The tortoises will lose liquids and may develop incurable diarrhoea. Further, parasitic diseases are promoted.
Since water my be very rare for months in the original habitats, tortoises discharge the end products of the protein metabolism in the form of uric acid crystals (urates) insoluble in water so that the organism will not lose water. This adjustment is extemely efficent unless too much protein is contained in the food. Too many urates in the organism due an excessive protein concentration in the forage can no longer be discharged. Renal failure and the extemely painful, lethal arthrolithiasis are the result.
Therefore, an appropriate diet for the European and Asian tortoises should only contain minor amounts of easily digestible substances, such as saccharides or carbohydrates, but a high percentage of structured crude fibre and it should not contain more than 5 to 8 % of protein.
By using a rich variety of plants, the requirments of the animals in liposoluble vitamins (A and E) can be covered completely or at least to a major part. Minerals and trace elements are also contained in a sufficient amount. The balanced ratio of calcium and phosphorus essential for the animals is achieved by processing fully grown plants and, if required, by additives.
Finally, it has to be mentioned that, for an adequate digestion of fibre-rich food, an optimum body temperature (of preferably 35 to 37°C) is indispensable. This is obtainable by sun bathing which must be simulated by installing a light-intensive lamp for locally heating the "sunny spot" up to a ground temperature of 35 to 40°C.
(The animals, however, also need cool retreats!)
Light and radiation warmth increase the activity and appetite of the animals.

How does Food in the Natural Habitat look like?

Tortoises are wild animals which were domesticated by humans. It is therefore the duty of the keeper to feed his pets appropriately. Wild Tortoises are often found in scanty environments and are obviously well adapted to a meagre diet. Pet tortoises, however, are often overfed and yet malnourished: "Their diet contains to much protein and they consume large amounts of easily digestible carbohydrates contained in unsuitable food. At the sametime they lack crude fibre and vital substances."

Why feed PRE ALPIN Testudo?

PRE ALPIN Testudo is the ideal basic diet for Tortoises. The types PRE ALPIN Testudo Herbs, Fibre and Baby contain the incomparable plant variety of the Upper Bavarian meadows. More than 60 different grasses and herbs growing on highly diverse poor-soil meadows make this product so valuable.

PRE ALPIN Testudo - the original, consists of selected grasses with a particularly low protein content and a particularly high crude fibre content. It is therefore particularly suitable in combination with fresh food. The reduced, but high-quality protein supply will, in particular, unburden liver and kidneys, and the detoxification of the body is promoted which is of particular importance during transition time and especially before the beginning of winter torpor.

The Institute of Zoology in Munich considers the PRE ALPIN Testudo product series a suitable diet for all tortoises.. The high crude fibre content of PRE ALPIN Testudo closely resembles the natural diet of tortoises. The digestion is enhanced, and the metabolism is relieved by the low protein content.

PRE ALPIN contains no additives such as pressing aids or protein-reducing admixtures such as straw or bran. The crumbling losses and the nutrient-consuming afterfermentation occurring during the conventional drying process are eliminated. Therefore the nutrients, the abundant and the trace elements as well as the vitamins contained in the green plants are preservered to the largest extent.

How to feed PRE ALPIN?

In amount of PRE ALPIN Testudo or Testudo Herbs corresponding to the weight of the animal and adjusted to the feeding plan is moistened with water and offered freely.
PRE ALPIN Testudo Fibre and Baby may als offered in a dry state. Since tortoises are frequently somewhat picky they should be given the time to get accustomed to unknown food - and please keep in mind that the food has to be replaced every day. Usually it takes a while until unknown food is accepted.

The most reliable way to get your pet accustomed to PRE ALPIN Testudo ist to mix it with known food.

The daily replacement of food that has not been eaten by fresh food is of vital importance.

Tortoises must always have free access to fresh water. Since most tortoises will only drink while they are taking a bath the most suitable water container is a flat bowl of a sufficient size to accommodate the whole animal.
