ABSTRACT This study aimed to evaluate the viability of using a non-invasive digital monitor to monitor heart rate (HR) and motility during the embryonic development of Pantanal alligator (Caiman yacare) using Egg Buddy ® , at different incubation temperatures. The collection of the eggs followed the Ranching system and egg identification, transportation, and incubation were performed with the required care; all eggs were incubated with 90% humidity at 29°C for the first 45 days. Thereafter, the incubation temperature was either maintained at 29°C, increased to 33°C or maintained at 29°C and embryos simultaneously treated with 4-aminopyridine on days 46, 47, 48, and 49 (29°C-4AP). Embryo movement was measured with a digital non-invasive monitor on days 30, 35, 42, 49, 56, and 60, at which point embryos were sacrificed. In the statistical analysis no differences were observed between the groups for the temperature (33°C and 29°C); for motility, a difference was observed at day 49 for the 29°C-4AP group. This revealed that the non-invasive evaluation method can be used to verify embryonic motility and HR effectively in Caiman yacare embryos.
