“…Conversely, this finding is inconsistent with the results of the red-footed tortoise ( Chelonoidis carbonaria ), a forest-dwelling herbivorous tortoise. No significant difference was observed in the growth of the red-footed tortoise when fed with starch and fiber [ 31 ]. Apart from that, there are no other research reports on the utilization of carbohydrate sources in reptiles to date.…”

A 60 day feeding trial was conducted to evaluate the impacts of dietary carbohydrates with different complexities and configurations on the growth, plasma parameters, apparent digestibility, intestinal microbiota, glucose, and lipid metabolism of soft-shelled turtles (Pelodiscus sinensis). Four experimental diets were formulated by adding 170 g/kg glucose, fructose, α-starch, or cellulose, respectively. A total of 280 turtles (initial body weight 5.11 ± 0.21 g) were distributed into 28 tanks and were fed twice daily. The results showed that the best growth performance and apparent digestibility was observed in the α-starch group, followed by the glucose, fructose, and cellulose groups (p < 0.05). Monosaccharides (glucose and fructose) significantly enhanced the postprandial plasma glucose levels and hepatosomatic index compared to polysaccharides, due to the un-inhibited gluconeogenesis (p < 0.05). Starch significantly up-regulated the expression of the genes involved in glycolysis, pentose phosphate pathway, lipid anabolism and catabolism, and the transcriptional regulation factors of glycolipid metabolism (srebp and chrebp) (p < 0.05), resulting in higher plasma triglyceride levels and lipid contents in the liver and the whole body. The fructose group exhibited a lower lipid deposition compared with the glucose group, mainly by inhibiting the expression of srebp and chrebp. Cellulose enhanced the proportion of opportunistic pathogenic bacteria. In conclusion, P. sinensis utilized α-starch better than glucose, fructose, and cellulose.

“…4 This species is native to South America and can be found from Panama to Paraguay, as well as parts of Bolivia, Brazil, Colombia, Ecuador, and Peru. 5 C. carbonaria is a diurnal and terrestrial animal with a compact body and strong cylindrical limbs, ideal to support its heavy carapace and walk in rough terrain. 4,5 They are opportunistic omnivores in general, and their diet is heavily influenced by the seasonal availability of food.…”
