| Perfil anal¡tico das progestinas fecais nas fases de puberdade e ciclicidade ovariana em On‡a Pintada; gesta‡Æo e lacta‡Æo em Gato Mourisco | |
| 2008 Full Book | |
The present study had as objective to use the technique of enzyme immunoassay (EIA) with monoclonal antibody CL425 in the dosage of faecal progestin to characterize the profile during ovarian activity beginning and estral cycle in jaguar (_Panthera onca_) and gestation and lactation in jaguarondi (_Puma yagouaroundi_). Three female jaguars were studied in distinct phases (pre-pubertal n=2 and adult n=1) and three female jaguarondi were studied during two distinct phases (gestation n=2 and lactation n=3). The EIA used was validated for faecal progestin measurement in jaguar and jaguarondi (r=0,98, p=0,0078; r=0,97, p=0,0130, respectively). The beginning of progesterone production for pre-pubertal animals was in September and November. Elevations of progestin in the adult jaguar were not supported, showing that there was not spontaneous ovulation for this specie. There was significant difference between medium progestin concentrations (p<0,001) of pre-pubertal and adult jaguars. It was not possible to identify different progestin concentrations during gestation and lactation in female jaguarondi. The faecal progestin profiles measured by radioimmunoassay (RIA) and enzyme immunoassay (EIA) corresponded well and were positively correlated (r=0,98, p<0,0001). |
