| Abstract Background: Removal of the follicular content by ultrasound-guided transvaginal follicle aspiration (TVFA) may fail to induce immediate atresia and loss of function, resulting in the occurrence of residual follicles (RF). The aims of this study were to characterize the blood flow in RF and to determine the effects of the treatment with estradiol benzoate on RF fate. Lactating, cyclic Holstein-Gir crossbred cows were used. In Experiment 1, follicular wave emergence (D0) was synchronized in cows (n = 10) and follicular growth was then monitored by transrectal ultrasonography from D0 to D8, followed by TVFA of the largest follicle present on the ovaries 24 h later. Color Doppler ultrasound imaging was used to examine blood flow on the follicular... |

| Resumo: Os parâmetros fisiológicos e reprodutivos de bovinos sofrem influencia das elevadas temperaturas e umidade relativa do ar existentes em regiões tropicais. Os objetivos deste estudo foram avaliar os efeitos do estresse por calor sobre parâmetros fisiológicos (temperatura vaginal-TVg., frequência respiratória-FR e frequência cardíaca-FC), índice de pulsatilidade (IP) e índice de resistência (IR) arterial, bem como a vascularização de folículos pré-ovulatórios e do corpo lúteo (CL) de vacas Girolando não lactantes, previamente classificadas como resistentes ou sensíveis ao estresse térmico. Vinte vacas multíparas foram estabuladas em câmara climática (índice de temperatura e umidade ? ITU médio=83,13) ou em galpão freestall (ITU médio=66,51),... |

| The effects of feeding urea on embryo production, quality and developmental stages and follicular status at the beginning of a superovulatory treatment of Toggenburg does fed urea diet were investigated in this study. Eighteen females were randomly allocated to receive diets with: no urea (control, n=8), and 2.4% urea dietary dry matter (n=10) UDM. The embryo recovery was performed at day 7 or 8 of estrus cycle by transcervical technique and classified according to quality and developmental stage. The follicular status was determined by transrectal ultrasonography at the first day of FSH injection. The number and quality of embryos were not affected by dietary urea concentration. Embryos from does treated with 2.4% UDM were recovered at advanced stage.... |

| Abstract Genomic imprinting is an epigenetic mechanism that leads to parental-allele-specific gene expression. Approximately 150 imprinted genes have been identified in humans and mice but less than 30 have been described as imprinted in cattle. For the purpose of de novo identification of imprinted genes in bovine, we determined global monoallelic gene expression in brain, skeletal muscle, liver, kidney and placenta of day ∼105 Bos taurus indicus × Bos taurus taurus F1 conceptuses using RNA sequencing. To accomplish this, we developed a bioinformatics pipeline to identify parent-specific single nucleotide polymorphism alleles after filtering adenosine to inosine (A-to-I) RNA editing sites. We identified 53 genes subject to monoallelic... |
