Crocodile & Alligator

Effects of different feed types on intestinal microbial community diversity and intestinal development of newborn Siamese crocodiles

Conventional alligator farming, characterized by reliance on chilled fish meat, faces significant challenges, including risks of bacterial contamination and nutritional imbalances. These issues heighten increasing disease susceptibility and threaten industry sustainability, underscoring the critical need for developing nutrient-dense, low-pathogenicity compound...

Effect of different infrared basking lamps on the heating effectiveness and desiccation of gelatine models: Implications for zoo animal husbandry

Artificial heating via lamp technology is a key feature of the husbandry of many captive animals, especially ectotherms. Short wave infrared (IRA) is theoretically more efficient in raising animal core temperature than medium (IRB) and long wave infrared (IRC) as...
