The longitudinal profiles of the sexual steroid's metabolites, progesterone and estrogen, and glucocorticoids were analyzed for 22 events (pregnancy, birth and breastfeeding) of 8 ocelots kept in captivity. Three events came from the Embryo Transfer (TE) and were compared against the ones that were gestated by natural fertilization. The statistical analysis demonstrated that the differences were highly significative during the initial (P<0001) and middle stages (P<0.007) of pregnancy and lactation (P<0,0015) periods for the progesterone metabolites. The descriptive analysis suggests a ovarian activity for the species during the lactation period, once detected the estrogen metabolites peaks during some events. A study was also performed, concerning the maternal behavior of 3 female through video-monitoring of the first months of lactation (n=3989,5 hours observed). The species that were kept in captivity spent more time resting and caring the puppy, entering it's shelter between 5:00h and 8:00h (61,3%) and there staying during 8 hours average. Other behavior analysis suggests that the stress level is a predominant fact in the success of the establishment of the puppy. A behavior variable performed by the female, by entering the shelter for a repeated number of times was linked to the stress level, being possible to assess the adrenal response by the secretion of glucorticoids and perform it's phisiological validation. It is expected by this means, a contribution for a change in the critical scene of the population that is kept in captivity, considering the puppies' low birth rate and high mortality rate, specially during its first months. |
