Anticipation of estrus and ovulation in Nelore heifers with low antral follicle...
Oliveira Júnior, Jair Sábio de; Silva, George Moreira da; Moreira, Elizângela Mírian; Andrade, Jéssica Souza; Nunes, Vanessa Rachele RibeiroEl objetivo de este estudio fue establecer la relación entre el conteo de folículos antrales (AFC), el tiempo de pubertad y la respuesta ovárica en novillas Nelore sometidas a protocolos inseminación artificial a tiempo fijo (TAI). Novillas Nelore prepubescentes (Bos indicus; n = 30) fueron examinadas mediante ultrasonido transrectal y se grabaron videos de los ovarios para posterior CFA (≥ 3 mm). Después de AF...
Integrated agricultural production systems and the effects of the animal component
Anjos, Mariana Moreira dos; Pazdiora, Raul Dirceu; Andrade, Evelyn Rabelo; Vieira , Aline da Silva; Barboza, Bruno NascimentoA large part of the cattle herd in Brazil is found in pasture systems in intertropical areas, such as the Amazon. Given the need to seek greater environmental and economic sustainability of livestock, this work aimed to discuss the introduction and benefits of the animal component in integrated systems of agricultural production. The review was based on the references of bibliographic research collected through...
Induction of puberty in Bos indicus heifers in the western Amazon region
Gonzalez, Suellen Miguez; Assunção, Igor Emanuel Gomes; Duarte, James; Oliveira, Carlos Henrique Andrade; Guedes, Tales André; Morotti, FábioThe objective of this study was to evaluate the efficiency and cost of two distinct hormonal protocols for induction of puberty in Bos indicus heifers in the western Amazon region. Nelore prepubertal heifers (n = 127) aged 20 to 24 months (21 ± 0.3 months) and weighing 300 to 340 kg (318 ± 7 kg) were submitted to two distinct protocols for induction of cyclicity. Females were previously submitted to two ovarian...

Silva, José Roberto Viana; Báo, Sônia Nair; Lucci, Carolina Madeira; Carvalho, F.C.A.; Andrade, Evelyn Rabelo; Ferreira, M.A.L; Figueiredo, José RicardoThe present work has investigated the morphological and ultrastructural changes occurring during degeneration of goat preantral follicles preserved in vitro and showed quantitative data about the distribution of follicular degeneration types in the control and after preservation in coconut water solution or Braun–Collins solution at different temperatures (4, 20 or 39°C) and incubation times (4, 12 or 24 h). At...
Effect of Braun-Collins and Saline solutions at different temperatures and incu...
Carvalho, Fabíola Christian Almeida de; Lucci, Carolina Madeira; Silva, José Roberto Viana; Andrade, Evelyn Rabelo; Báo, Sônia NairThe present work has investigated the efficiency of Braun-Collins and Saline (0.9%) solutions in the conservation of goat preantral follicles in situ, at different temperatures and incubation times. For each animal the ovarian pair was divided into 19 fragments. One ovarian fragment was taken randomly and immediately fixed (control). The other 18 ovarian fragments were randomly distributed in tubes containing B...

Matos, Maria Helena Tavares de; Andrade, Evelyn Rabelo; Lucci, Carolina Madeira; Báo, Sônia Nair; Silva, José Roberto Viana; Santos, R.R.The objective was to determine the morphological and ultrastructural features of sheep primordial follicles preserved in either 0.9% saline solution or TCM 199 at different temperatures. Soon after death, the ovarian pair of each ewe (n=5) was divided into 25 fragments. One fragment was immediately fixed for morphological evaluation (control). The other 24 fragments were randomly distributed in tubes containing...
