A deterministic simulation study of embryo marker-assisted selection for age at first calving in Nellore (Bos indicus) beef cattle
(Sociedade Brasileira de Genética, 2007-01-01)
We used deterministic simulation of four alternative multiple ovulation and embryo manipulation (MOET) closed nucleus schemes to investigate the benefits of using marker-assisted selection (MAS) of Nellore (Bos indicus) ...
RELATIONSHIP BETWEEN PLASMA 17-BETA ESTRADIOL ON THE DAY OF ESTRUS AND NUMBER OF VIABLE EMBRYOS IN BOS-INDICUS (NELLORE) COWS SUPEROVULATED WITH FSH
(Associação Brasileira de Divulgação Científica (ABRADIC), 1994-07-01)
Thirteen cows, Bos indicus, of the Nellore breed were superovulated with 22 mg of follicle stimulating hormone (FSH) administered by intramuscular route during four consecutive days (D10, D11, D12 and D13), starting on the ...
Luteal Function and Follicular Growth Following Follicular Aspiration During the Peri-Luteolysis Period in Bos indicus and Crossbred Cattle
(Wiley-Blackwell, 2012-04-01)
Follicular estradiol triggers luteolysis in cattle. Therefore, the control of follicle growth and steroidogenesis is expected to modulate luteal function and might be used as an anti-luteolytic strategy to improve embryo ...
Synchronization of ovulation in beef cows (Bos indicus) using GnRH, PGF2 alpha and estradiol benzoate
(Elsevier B.V., 2000-03-15)
The objective of this study was to evaluate protocols for synchronizing ovulation in beef cattle. In Experiment 1, Nelore cows (Bos indicus) at random stages of the estrous cycle were assigned to 1 of the following treatments: ...
Effects of scrotal insulation in Nellore bulls (Bos taurus indicus) on seminal quality and its relationship with in vitro fertilizing ability
(Elsevier B.V., 2008-12-01)
The objectives of this study were to assess the effects of induced testicular degeneration in Bos taurus indicus (Nellore) bulls on changes in seminal characteristics and fertilizing ability of sperm. Four Nellore bulls ...

Influence of cAMP modulator supplementation of in vitro culture medium on Bos taurus indicus embryos
(2020-01-01)
The effectiveness of the use of natriuretic peptide C (NPPC) in the blocking of meiosis has already been proven in several species. However, there are no reports on the use of NPPC in the activation of metabolic processes ...
Effects of calcium salts of soybean oil on factors that influence pregnancy establishment in Bos indicus beef cows
(Amer Soc Animal Science, 2014-05-01)
The objective of this experiment was to compare fatty acid (FA) concentrations in plasma and reproductive tissues as well as hormones and expression of genes associated with pregnancy establishment in beef cows supplemented ...
Temporal analysis of prostaglandin F2 alpha receptor, caspase 3, and cyclooxygenase 2 messenger RNA expression and prostaglandin F2 alpha receptor and cyclooxygenase 2 protein expression in endometrial tissue from multiparous Nelore (Bos taurus indicus) cows treated with cloprostenol sodium during puerperium
(Elsevier B.V., 2015-01-15)
The use of cloprostenol sodium in puerperium is questionable, as both favorable and unfavorable responses during the uterine involution process have been reported in the literature. This study is based on the hypothesis ...
