Última Effects of prostaglandin administration 10 days apart on reproductive parameters of cyclic dairy nulliparous goats Arq. Bras. Med. Vet. Zootec. Fonseca,J.F.; Maffili,V.V.; Santos,A.D.F.; Fürst,R.; Prosperi,C.P.; Rovay,H.; Souza,J.M.G.; Torres,C.A.A.. This study reported the effects of prostaglandin (PGF2a) administration 10 days apart on reproductive parameters of cyclic artificial inseminated (AI) nulliparous Alpine (n=9) and Saanen (n=9) goats. Animals received two doses of 22.5mg PGF2a 10 days apart. After 1st and 2nd PGF2a administrations, estrus was monitored at 12 h intervals, with a buck teaser. Plasma progesterone concentration (ng/mL) was determined from blood sampled on day 0 (1st PGF2a) and the following 5, 10 (2nd PGF2a), 15, 20, 25 and 30 days. After the onset of the second estrus, females were transrectally (5 MHz probe) scanned at 4 hour intervals until at least 8h after ovulation. Pregnancy was checked through transrectal ultrasound on days 20, 25, 30, 35 and 90 after insemination. All...

Bras. Med. Vet. Zootec. Esteves,L.V.; Brandão,F.Z.; Cruz,R.C.; Souza,J.M.G.; Oba,E.; Facó,O.; Fonseca,J.F.. The objective of this study was to evaluate the efficiency of two doses of PGF associated or not to hCG on the associated reproductive parameters in dairy goats. A total of 29 goats received two doses of 30µg d-cloprostenol latero-vulvar at a 10 day intervals (Day 1 and Day 10). The does were allocated according to body weight and body condition score into two treatments, to receive hCG (250IU) or saline at estrus onset. After the second dose of PGF, estrus was monitored and ultrasound exams were performed twice daily. All does were inseminated 16h after estrus onset. Blood collection was performed every day for progesterone assay. The use of hCG at estrus onset did not affect any studied parameter and therefore the data were pooled. Estrous response rate...

Ano: 2013 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0102-09352013000600001 Reproductive parameters of Santa Inês ewes submitted to short-term treatment with re-used progesterone devices Arq. Bras. Med. Vet. Zootec. Pinna,A.E.; Brandão,F.Z.; Cavalcanti,A.S.; Borges,A.M.; Souza,J.M.G.; Fonseca,J.F.. The aim of this study was to verify the efficacy of reusing intravaginal progesterone (P4) devices on the reproductive parameters in Santa Inês ewes. Females received intravaginal P4 devices for their first, second or third use for five days plus 300 IU eCG IM and 5mg dinoprost laterovulvar 24h before device removal. Blood was collected at different moments. Transrectal ultrasonography was performed from device removal to ovulation. Part of the ewes were submitted to artificial insemination by laparoscopy (IAL - n=55) with fresh semen, whereas the rest were bred by fertile rams (n=41). On the initial 18 h, ewes that received devices for the first time showed higher P4 concentrations (5.1±1.8 vs 3.5±1.4 vs 2.4±1.1 - P<0.05). However, after the first 48h...
