“…Studies evaluating serum hormone levels confirmed that some wild cats like tiger (Panthera tigris) , snow leopard (Panthera uncia) (Schmidt et al, 1993), jaguars (Panthera onca) (Wildt et al, 1979) and cougars (Puma concolor) , have induced reflex ovulation, similar to the domestic cat (Johnston et al, 1996;Shille et al, 1979;Tsuitsui & Stabenfeldt, 1996).…”

“…In domestic cats (Felis catus), the reproductive seasonality is related to photoperiod (Johnston et al, 1996;Shille et al, 1979;Tsuitsui & Stabenfeldt, 1996), whereas in wild animals, it is also related to high or low food supply during the seasons (Ewer, 1975).…”

“…São poliéstricas continuas em regiões próximas à Linha do Equador (Johnston et al, 1996). A atividade sexual é iniciada com o aumento do número de horas luz por dia e a inatividade sexual ocorre quando o número de horas decresce (Pope, 2000).…”

“…The domestic cat is classically defined as a seasonal polyestrus species in geographic regions with marked climatic seasons (Jemmett & Evans, 1977;Pope, 2000;Johnston et al, 1996). These animals' cycle throughout the year under Brazilian climatic conditions, although presenting an increase in the interestrus phase in the fall and the winter, does not present seasonal anestrus (Ávila et al, 2003).…”

“…In pregnant animals, the luteal phase lasts until birth, for approximately 60 days (Johnston et al, 2001). According to Johnston et al (1996), the size of the litter ranges from one to five offsprings with an average of 3.7 per birth, and there is no relationship between the offspring number and pregnancy duration.…”

Indução exógena da atividade ovariana e da ovulação e transferência de embriões a fresco em gatas domésticas (Felis catus)Os objetivos deste trabalho foram avaliar a estimulação exógena da atividade do ovário e a definição de protocolos para recolhimento e transferência de embriões em gatos domésticos, para aplicação potencial em espécies selvagens ameaçadas de extinção. Foram utilizados 16 gatas domésticas adultas e dois machos adultos reprodutores, mantidos no gatil experimental do setor de Morfologia do DVT-UFV. Todas as fêmeas receberam uma única aplicação de 150 UI de Gonadotrofina Coriônica Equina (eCG) no pós-estro, como indutor da atividade ovariana e, 80 a 84 horas após, receberam uma única aplicação de 100 UI de Gonadotrofina Coriônica Humana (hCG), como indutor da ovulação. Após a aplicação de hCG, apenas as gatas doadoras foram naturalmente acasaladas. As gatas receptoras receberam estímulo extra de indução da ovulação por meio da manipulação de um swab intravaginal. Cinco a seis dias após a aplicação de hCG, as gatas doadoras foram submetidas a uma laparotomia, para a coleta dos embriões, a qual foi efetuada mediante The objective of the present study was the exogenous stimulation of ovarian activity and definition of embryo collection, and transfer protocols, in the domestic cat for potential application in non-domestic endangered species. Sixteen adult queens and two adult male reproducers kept in the experimental cat house at the Morphology sector at the Veterinary Department (DVT), UFV, were used in this study. All the queens received a single application of 150 IU Equine Chorionic Gonadotropin (eCG) in the post estrus to induce ovarian activity and 80 to 84 hours later, received a single application of 100 UI Human Chorionic Gonadotropin (hCG) to induce ovulation. After hCG application, only the donor queens were naturally mated. The receptor queens received extra stimulus for induction of ovulation through manipulation of an intravaginal swab. Five to six days after hCG application, the donor queens were subjected to a laparotomy for embryo collection that was performed by trans-horn uterine washing. On average, six embryos were surgically inovulated. They were classified as type I and III compact morula and blastocysts in four receptor queens. Three animals presented pregnancy confirmed by ultrasound at day 36 and two of these animals gave birth to litters of two and four offsprings, respectively, at 66 and 63 days after induction of ovulation. Except for one still birth, all the offspring developed normally.
