Ovulation parameters in nulliparous and multiparous Serrana goats
Simões, João; Azevedo, Jorge Manuel Teixeira de; Almeida, José Carlos; Fontes, Paulo J.; Mascarenhas, RamiroThe aim of this study was to characterize the ovulation parameters in nulliparous (n=24) and multiparous (n=14) Serrana goats during the breeding season. Oestrus was synchronised with two cloprostenol injections (50 µg, 10 days apart). Transrectal ovarian ultrasonographic scanning was performed daily, during 2 consecutive oestrous cycles. Day of ovulation was considered when large follicles disappeared and the ...

Preovulatory LH peak and time of ovulation in nulliparous and primiparous goats...
Simões, João; Baril, Gérard; Cunha, Teresa; Azevedo, Jorge Manuel Teixeira de; Mascarenhas, RamiroThe aim of the present study was to determine the time of preovulatory LH peak and ovulation in anoestrous goats, after stimulation by male effect. Seven nulliparous and eight primiparous Serrana goats were isolated from bucks during nonbreeding season. Anoestrus was confirmed by circulating progesterone levels. A 6-day progestagen treatment (Chronogest® 45 mg FGA, Intervet, Holland) was performed to synchroniz...
Effect of eCG and progestagen on ovarian follicle population in goats
Ribeiro, Catarina; Teixeira, Victor; Mascarenhas, Ramiro; Baril, Gérard; Azevedo, Jorge Manuel Teixeira de; Simões, JoãoThe aim of present study was to evaluate the response of ovarian follicle population to eCG/progestagen treatment in goats. In second half of February, seven Serrana goats (G-eCG) received 250 UI of eCG (Intergonan®, Intervet, Holland) at the removal of intravaginal sponges impregnated with 20 mg of flugestone acetate (Chronogest® CR 20 mg, Intervet, Holland) and kept in place during 6 days. Six other Serrana g...
Lifespan of a luteinised ovarian cyst, hormonal profile and uterine ultrasonogr...
Simões, João; Baril, Gérard; Azevedo, Jorge Manuel Teixeira de; Mascarenhas, RamiroThe genesis, evolving and spontaneous regression of a single luteinised ovarian cyst in a cyclic nulliparous Serrana goat, during the breeding season, were presented. Daily ovarian and uterus transrectal ultrasonography scanning was performed during two consecutive (induced and natural) oestrous cycles. Blood samples were collected every 4 h during the first 24 h after onset of each oestrus, detected by a vasec...
Oestrus and ovulatory response of goats with different parity to male effect an...
Simões, João; Baril, Gérard; Cunha, Teresa; Azevedo, Jorge Manuel Teixeira de; Teixeira, Victor; Ribeiro, Catarina; Mascarenhas, RamiroThe aim of this work was to determine the oestrous and ovulatory activity in goats with different parity after male effect associated to short-term progestagen treatments. In April, 15 nulliparous (NG; 25.2 ± 0.7 Kg) and 22 multiparous (MPG; 40.3 ± 0.7 Kg) Serrana goats were treated with 20 (NG20=7; MPG20=11), or 30 mg (NG30=8; MPG30=11) of fluorogestone acetate sponges (Chronogest® CR 20 mg / Chronogest® 30 mg...
Torção de mesentério – um caso clínico
Soares Figueiredo, Teresa; Lavrador, Catarina; Alexandre, Nuno; Mascarenhas, RamiroOs autores descrevem um caso clínico numa cadela Boxer de dezoito meses, cujo diagnóstico definitivo de torção mesentérica, foi alcançado numa laparotomia exploratória de urgência. A cirurgia foi um sucesso e passados dezoito meses da mesma, a cadela apresenta-se em bom estado geral e exame clínico normal. Esta é uma situação pouco frequente nos nossos animais de companhia, de prognóstico grave e cuja taxa de m...
Ovulation and oestrus synchronization using fluorogestone acetate vaginal spong...
Valentim, Ramiro; Azevedo, Jorge Manuel Teixeira de; Almeida, José Carlos; Correia, Teresa Montenegro; Mascarenhas, Ramiro; Fontes, Paulo J.In order to determine the precise time of induced ovulation and oestrus after progestagen treatment in nulliparous Serrana goats, nine females aged between 2 and 3 years were used. In May, an intravaginal sponge impregnated with 45mg of fluorogestone acetate was inserted for 12 days with the injection (i.M.) of 500UI of eCG and 50 µg of cloprostenol at sponge removal time. Oestrus was detected using a vasectomi...
Redução da morbilidade iatrogénica no local dador de enxerto ósseo. Estudo de a...
Coelho, Paulo; Lavrador, Catarina; Mascarenhas, Ramiro; Leitão, Jorge; Gorna, KatalinaO objectivo final da cirurgia óssea reconstrutiva é atingir o restitution ad integrum estrutural e funcional. O enxerto ósseo é extensamente utilizado na reconstrução óssea. A crista ilíaca e a tuberosidade tibial são dos locais mais frequentes como locais dadores de osso cortical e / ou esponjoso. O procedimento é traumático e associado potencialmente com morbilidade de local dador e dificuldade na regeneração...
Follicular dynamics in Serrana goats
Simões, João; Almeida, José Carlos; Valentim, Ramiro; Baril, Gérard; Azevedo, Jorge Manuel Teixeira de; Fontes, Paulo J.; Mascarenhas, RamiroTwenty-two Serrana goats were studied through two successive estrous cycles in order to characterize their follicular dynamics during the breeding season. The ovaries of the goats were scanned daily by realtime ultrasonography and all follicles ≥3mm were measured and classified. The data were classified by the number of follicular waves per goat to test the hypothesis that temporal and morphological differences...
