Feeds formulated with alternative ingredients for bullfrog tadpoles (Lithobates catesbeianus)

Research, Society and Development, 2022
Several foods are available for the formulation of rations in Brazil; however, the effectiveness of a few of these foods has been evaluated in diets for bullfrog tadpoles (Lithobates catesbeianus). This study aimed to evaluate alternative foods (worm meal, peeled banana, peeled pumpkin, and peeled avocado) with different levels of crude protein and ...

Non-linear growth models for bullfrog tadpoles Modelos de crescimento não-lineares para girinos de rã-touro

Ciência e Agrotecnologia, 2012
Describing animal growth rate using non-linear models allows a detailed evaluation of growth behavior. Four non-linear models were used to fit weight gain and total length data of bullfrog (Lithobates catesbeianus) tadpoles, as follows: Gompertz, Y = A ...

Effect of dietary protein:lipid ratio on growth and body composition in bullfrog (Lithobates catesbeianus)

Revista Brasileira de Zootecnia, 2023
- A feeding trial was performed to assess dietary protein:lipid ratios for the grow-out phase of the bullfrog ( Lithobates catesbeianus ). Nine balanced isoenergetic diets were formulated, combining three different protein levels (300, 400, and 500 g kg −

Potential effects of climate change on the distribution of invasive bullfrogs Lithobates catesbeianus in China

Acta Herpetologica, 2020
Climate plays important roles in determining the geographical distribution of species, including the invasion area of alien species. Little is known, however, about the influence of climate change on the distribution area of invasive amphibian species in

Prevalence of Ranavirus Infection in Three Anuran Species across South Korea

Viruses, 2022
To cope with amphibian die-offs caused by ranavirus, it is important to know the underlying ranavirus prevalence in a region. We studied the ranavirus prevalence in tadpoles of two native and one introduced anuran species inhabiting agricultural and ...

Control of lung ventilation following overwintering conditions in bullfrogs,Lithobates catesbeianus [PDF]

Journal of Experimental Biology, 2016
Ranid frogs in northern latitudes survive winter at cold temperatures in aquatic habitats often completely covered by ice. Cold-submerged frogs survive aerobically for several months relying exclusively on cutaneous gas exchange while maintaining temperature-specific acid-base balance.
