EVALUATION OF COMMERCIAL TORTOISE AND TURTLE FEEDS

Captive chelonians should be fed a natural diet to achieve growth rate similar that of free-ranging animals. A wide range commercially formulated foods dedicated is available. Feeding commercial has the advantage convenience. On other hand, species-specific information on nutritional requirements not available yet. The aim this study was analyse and evaluate pellets feeds for chelonians. Commercial (ntortoise = 7, nturtle from 6 companies) carnivorous aquatic turtles herbivorous terrestrial tortoises, turtle (lyophilised beef heart, dried invertebrates, whole frozen fish) were bought in pet shops. Whole fish served as reference feed turtles. chemical composition well calcium (Ca) phosphorus (P) contents determined. Single-sample t-test used with label null hypothesis results own parallel analyses crude protein (CP), ether extract (EE), fibre (CF), Ca P. labelling some deficient nutritive values, or P data missing (tortoise pellets: 4 out 7; 5 7). differed significantly (p<0.05) our analysis 13 14 pellets. None tortoise met animals completely. Because inadequate Ca:P ratio only one pellet could accepted. Accordingly, none can recommended main feed.

Na voljo širok izbor komercialno pripravljene hrane za želve. Prednost hranjenja želv s hrano priročnost, vendar podatki o prehranskih potrebah posamezne vrste še niso na voljo. Namen te raziskave bil analizirati ovrednotiti komercialne pelete krmo V trgovinah smo od podjetij kupili (npeleti vodne želve npeleti kopenkse 7) mesojede rastlinojede kopenske ter drugo (liofilizirano goveje srce, posušene nevretenčarje zamrznjene cele ribe). Zamrznjene ribe uporabili referenčno Določili kemično sestavo vsebnost kalcija fosforja (P). Za ničelno hipotezo T-test enega vzorca etiketi rezultate lastne paralelne analize surove beljakovine (an gl. proteins, CP), ekstrakt etra (angl. extract, EE), surovo vlaknino fibre, CF), Oznake nekaterih peletov so bile pomanjkljive, saj manjkali hranilnih vrednostih, Podatki se bistveno razlikovali (p < 0,05) rezultatov naše pri vrst peletov. Nobeni peleti celoti izpolnjevali potreb živali. Zaradi neustreznega razmerja : ustrezno določili le eno izmed 7 želve, zaradi česar nobenih komercialnih nismo priporočljivih glavno ali edino Ključne besede: prehrana; peleti; presnovna bolezen kosti;
