Induction of synchronized estrus in dairy goats with different gonadotrophins. Author(s): FONSECA, J. F. da; BRUSCHI, J. H. The objective of this study was to evaluate lhe efficiency of two gonadotrophins in induction of estrus in dairy goats. A total of 47 dairy goats were randomly divided according to breed into two trea... ... Repository: BDPA Publication year: 2005
Use of hCG, eCG or p-FSH on estrus induction of goats and their effects on luteal dynamics and conception rate. Author(s): FONSECA, J. F. da The present study tested the hypothesis that hCG and pFSH stimulate the follicular development and consequently corpora lutea, in a manner equivalent to those induced by eCG in goat. Eighty-five Togge... ... Repository: BDPA Publication year: 2018
Effects of hCG administered 7.5 days after synchronous estrus induction during the non-breading season in Morada Nova ewes. Author(s): FONSECA, J. F. da; PEREIRA, V. S. do A.; GARCIA, A. R.; ESTEVES, S. N. This study was designed to assess the effects of human chorionic gonadotropin (hCG) administration 7.5 days after the end of synchronous estrus induction protocol in Morada Nova ewes in the non?breedi... ...

Induction of estrus in cyclic alpine goats with short-term progestagen protocols with or whithout eCG administration. Author(s): FONSECA, J. F. da; VIANA, J. H. M.; FACO, O. Repository: BDPA Publication year: 2010
Timed hormonal treatments in induction and synchronization of Saanen goats estrus during nonbreeding season. Author(s): FONSECA, J. F. da With the aim to evaluate reproductive performance of Saanen goats among different timed hormonal protocols during nonbreeding season, 30 females had the estrus cycles induced and synchronized by inser... ... Repository: BDPA Publication year: 2010
Estrus induction in the non-breeding season is not associated with hydrometra in dairy goats. Author(s): FONSECA, J. F. da Abstract: This study aimed to compare the prevalence of hydrometra (HD) at the end of the reproductive season in goats subjected (HORM and LIGHT) or not (Control-HORM and Control-LIGHT) to estrus indu... ...

Association of controlled light program, cloprostenol and gonadotropins for synchronous estrus induction and fixed time artificial insemination in dairy goats during the non-breeding season: preliminary results. Author(s): FONSECA, J. F. da Animal preparation prior to artificial insemination (AI) in goats usually involves a combination of intravaginal devices containing progesterone/progestagens plus PGF2?? analogues and gonadotropins, b... ...

Route of Oxytocin administration and nonsurgical embryo recovery in Santa Inês ewes after induction synchronous estrus. Author(s): FONSECA, J. F. da; PEREIRA, V. S. do A.; ESTEVES, S. N.; MACHADO, R. Abstract: Oxytocin has been used to promote cervical dilation with the objective to access uterus both in artificial insemination and transcervical embryo recovery in sheep and goats. The objective of... ... Repository: BDPA Publication year: 2016
Short, medium or long-term hormonal treatments for induction of synchronized estrus and ovulation in Saanen goats during the nonbreeding season. Author(s): FONSECA, J. F. da Abstract: The objective of this study was to compare the effect of hormonal treatment duration through the use of intravaginal sponges impregnated with 60 mg MAP for 6 (G6; n = 10), 9 (G9; n = 10) or... ... Repository: BDPA Publication year: 2013
Induction of synchronous estrus in Morada Nova ewes: effects of distinct progestagen duration regimen and non-surgical embryo recovery as a tool to access efficiency measurements. Author(s): ESTEVES, S. N.; CARVALHO, B. P.; FONSECA, J. F. da Abstract: The first stet for applying superovulation is to know the responsiveness of the ewe to different estrous synchronous protocol duration and possible implications on embryo yield. On the other... ... Repository: BDPA Publication year: 2019
