“…This explains the increase in hematocrit and the decrease in MCHC that occurred at the same evaluation time in both transport conditions. Like this study, a decrease in MCHC was demonstrated in adult bullfrogs evaluated 48 hours after biometric management (Santos et al 2023). However, these authors did not show an increase in MCV and hematocrit in these animals.…”

“…However, in this study, only an increase in plasma triglyceride levels was observed, with no evidence of an increase in cholesterol concentrations. Santos et al (2023) also found an increase in triglyceride levels in adult bullfrogs immediately after biometric management. These authors also demonstrated that triglyceride levels in frogs only decreased 24 hours after transportation, like the present study, with frogs transported without foam.…”

“…In addition, higher concentrations of solutes in the blood, especially erythrocytes contributing to the increased hematocrit percentage, may indicate a state of dehydration (Voyles et al 2012). A similar response pattern was observed in adult bullfrogs, where an increase in the number of erythrocytes and hematocrit was immediately observed after biometric management (Santos et al 2023). However, these authors observed a return to normal levels of these variables 6 hours after biometric management, similar to frogs transported in foam boxes in the present study.…”

“…Like the present study, these authors also observed a recovery in glucose levels, relative to control group animals, starting 24 hours after transportation. Santos et al (2023) observed an increase in glucose concentrations in adult bullfrogs immediately after biometric management, a common practice in bullfrog farms for adjusting feed supply and screening frogs in pens for size classi cation. However, these authors observed the recovery of glucose levels, compared to the control group, within only 6 hours after biometric management.…”

This study aimed to evaluate two transportation methods on the plasma biochemistry and erythrogram responses bullfrogs. The animals were transported for 10 hours in boxes without and with moistened foam. Then, the frogs' condition was evaluated 0, 6, 12, 24, and 48 hours after transportation. There was no mortality. The glucose in frogs, in both transportations, increased at 0 and 12 hours and returned to basal levels at 24 hours. Triglyceride increased in animals 0 and at 6 hours, in both transportations. After 12 hours, frogs transported with foam recovered, while the without foam recovered after 24 hours. Plasma proteins and globulins increased in frogs at 0 hours, under both transportations. After 48 hours, there was a reduction in plasma proteins in frogs transported without foam. Globulins decreased 24 hours in frogs transported without foam and after 48 hours under both transportations. Albumin increased in animals at 12, 24, and 48 hours. Frogs transported with foam had high albumin. The albumin/globulin ratio increased in frogs evaluated 24 and 48 hours, in both transportations. The number of erythrocytes was higher in frogs evaluated 0 hours, in both transportations, and recovered 6 and 12 hours in transported with and without foam, respectively. Hematocrit and hemoglobin were higher in frogs evaluated 0 hours and recovered after 6 hours, in both transportations. MCV increased in frogs transported with foam 48 hours after transportation. MCH decreased in frogs evaluated 12, 24, and 48 hours, in both transportations. In bullfrogs transported with foam, MCHC was lower.

This study aimed to evaluate two transportation methods (with moistened foam and without foam) for 10 h on blood parameters of bullfrogs 0, 6, 12, 24, and 48 h after transportation. There was no mortality. The glucose increased at 0 and 12 h after transportation and returned to baseline at 24 h in both transportations. Triglycerides increased at 0 and 6 h in both transportations and were restored 12 h after transport with foam and 24 h in transport without foam. Plasma proteins and globulins increased at 0 h after transportation under both transportations. After 48 h, there was a reduction in transport without foam. Globulins decreased 48 h under both transportations. Albumin increased at 12, 24, and 48 h after both transportations. Transport with foam had high albumin. The albumin/globulin ratio increased 24 and 48 h after both transportations. The number of erythrocytes increased at 0 h and recovered after 6 h in transport with foam and 12 h in transport without foam. Hematocrit and hemoglobin increased at 0 h and recovered at 6 h in both transportations. MCV increased 48 h after transportation with foam. MCHC decreased 12, 24, and 48 h after both transportations. MCH was lower in the transport carried out with foam.
