| ABSTRACT Inactivity is a common daytime behavior expressed by wild cats in zoos. It is not clear whether this inactivity is due to the constraints of the captive environment or is a result of a more natural behavior by these animals. Therefore, this work evaluated the behavior of two Panthera onca captive specimens, including their inactivity, during the evening/night period. The jaguars were filmed individually in different days, starting at 5:30 pm and finishing between 7:00 pm and 1:30 am, including non-feeding and feeding days. Regardless of whether they were fed or not, both jaguars expressed a significant rate of inactivity. In addition, when fed, one of the jaguars increased its movements and active behaviors, although its inactivity remained high,... |

| Ejaculate traits, testicular volume and plasma testosterone levels were determined once every two months for one year in 4 adult male jaguars (Panthera onca) housed at the São Paulo Zoo, SP, Brazil. Semen samples was collected by electroejaculation and analyzed for pH, total volume, motility (0-100%), status (0-5), total spermatozoa count and morphology. Blood samples was obtained by cephalic venipuncture immediately before the onset of electroejaculation and stored at -20ºC until assay of testosterone by RIA. Using a calliper, the length and width of each testis was measured and the values were combined to determine the testicular volume. Semen analyses demonstrated a high percentage of structurally abnormal sperm (mean = 51%) and low rates of motility... |
