| Eighty-nine of 144 isolates of Clostridium perfringens obtained from 187 samples of 71 bovine in several Brazilian states were submitted to esterase electrophoresis for typing. Mobilites electrophoresis, as parameter, were settled down by isolates from ATCC pattern of types A, B, C, and D. Of the 89 isolates, 43 (48.3%) were characterized as electrophoretic type A, 20 (22.5%) as D, 18 (20.2%) as C, and 3 (3.4%) as B. Five (5.6%) isolates did not identity with any type. Similarly, esterase electrophoresis enabled the typing of 94.4 % of the isolates, demonstrating to be an appropriate method for animal sample analyses. |

| Las contusiones tienen un impacto negativo sobre la calidad de la carne y son una fuente importante de información sobre el bienestar animal. Las contusiones reflejan fallas en las prácticas de manejo, diseño incorrecto de las instalaciones o falta de formación del personal. La carne de pH elevado es el resultado de una depleción del glucógeno antes de la matanza y la consecuente inhabilidad para acumular ácido láctico. Esta carne tiene apariencia seca, firme y oscura (DFD= dark, firm, dry), es menos tierna, tiene defectos de palatabilidad, es poco apreciada por el consumidor y facilita el desarrollo de microorganismos. Se estudió la presencia de contusiones en las canales bovinas y los aspectos relacionados con alteraciones en la calidad de la carne, como... |

| The objective of the present study was to improve the detection of B. abortus by PCR in organs of aborted fetuses from infected cows, an important mechanism to find infected herds on the eradication phase of the program. So, different DNA extraction protocols were compared, focusing the PCR detection of B. abortus in clinical samples collected from aborted fetuses or calves born from cows challenged with the 2308 B. abortus strain. Therefore, two gold standard groups were built based on classical bacteriology, formed from: 32 lungs (17 positives), 26 spleens (11 positives), 23 livers (8 positives) and 22 bronchial lymph nodes (7 positives). All samples were submitted to three DNA extraction protocols, followed by the same amplification process with the... |

| ABSTRACT The study evaluated the effect of transportation over long distances on cattle muscle tissue of submitted to emergency slaughter in slaughterhouses in northern Tocantins, Brazil. The evaluations consisted in pH, muscle and liver glycogen, muscle histopathology and creatine kinase (CK), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity. Animals were placed into two groups: Experimental Group (EG), consisting of 19 bovines intended for immediate emergency slaughter, and Control Group (CG), composed of 24 bovines slaughtered in accordance with the normal flow. CK and ALT levels were high in EG. AST did not differ between groups. EG showed higher muscle pH and mean of degenerate fibers, mainly on the intercostal. However,... |

| Paternity misidentification is harmful due to the reduction in annual genetic earnings of the population and because it endangers an efficient genetic improvement program. The objectives of the present study was to evaluate nine microsatellites in Paternity Testing and to investigate misidentification paternity frequency in families of Gyr breed bovines population. In the present experiment blood samples from forty Gir breed families ( bull / cow / calf ), registered pure breed in the Zebu Breeders Brazilian Association (ABCZ) were used. The most part of the microsatellites used in this work were recommended by the International Society of Animal Genetics (ISAG). The genomic DNA extraction was performed from whole blood samples. The microsatellites... |

| ABSTRACTHigh milk production, heat, physiological status and management impair reproduction in Holstein cows. The use of in vivo-produced embryos has been reported as an alternative to enhance pregnancy outcome in the tropics; however there are several limitations for its production, especially from variations in superovulatory responses. The in vitro production of embryos would avoid such variations, but few studies have been reported. This study aims to verify the effects of variables related to recipients under a program of routine in vitro embryo transfer on a commercial dairy farm in southeastern Brazil. It was hypothesized that pregnancy rates after transfer of ovum pick up or OPUderived embryos (ET) to lactating Holstein recipients may be influenced... |

| Glucocorticoids modulate ovarian function in cattle. However, their regulatory mechanisms have not been fully elucidated. In the present study, we examined gene expression of two glucocorticoid-metabolizing enzymes, a bidirectional 11β-HSD type 1 (11HSD1) and a dehydrogenase 11β-HSD type 2 (11HSD2), and glucocorticoid receptor (GR) in bovine follicles during follicular maturation and atresia. Granulosa cells (GCs) and theca interna layers (TIs) were harvested from follicles classified as small growing, dominant, preovulatory, early atretic and late atretic follicles. The expression levels of 11HSD1, 11HSD2 and GR mRNA were quantified by real-time PCR. In the healthy follicles, expression of 11HSD1 mRNA increased as follicles matured, both in GCs and TIs. A... |

| Aberdeen Angus beef cattle from the Brazilian herd were studied genetically using restriction fragment length polymorphism (RFLP) of the kappa-casein - HinfI (CSN3 - HinfI), beta-lactoglobulin - HaeIII (LGB - HaeIII) and growth hormone AluI (GH- AluI) genes, as well as four microsatellites (TEXAN15, CSFM50, BM1224 and BM7160). The RFLP genotypes were determined using the polymerase chain reaction (PCR) followed by digestion with restriction endonucleases and electrophoresis in agarose gels. With the exception of the microsatellite BM7160, which was analyzed in an automatic sequencer, the PCR products were genotyped by silver staining. The allele and genotype frequencies, heterozygosities and gene diversity were estimated. The values for these parameters of... |

| Bovine herpesvirus 5 (BoHV-5) meningoencephalitis is one of the main causes of mortality by encephalopathy in Brazilian cattle herds. However, the neurological signs observed are common to several encephalopathies and do not contribute decisively to a diagnosis. In order to verify hematological and cerebrospinal fluid (CSF) changes, blood and CSF samples from naturally and experimentally infected bovines were evaluated. In natural cases (n=17), the samples were collected only once, and in experimental cases (n=7), the samples were sequentially obtained throughout disease progression. While routine methods were used to examine the samples, BoHV-5 infection was confirmed by a PCR assay. Blood analyses did not reveal any consistent hematological alterations... |

| The aim of this study was to identify heparin-binding proteins (HBPs) in seminal plasma of Nellore (Bos taurus indicus) bulls. Bulls (n=4), 30-36 months old, 500-550kg with satisfactory seminal quality were selected. After the centrifugation, samples of the seminal plasma were pooled and the HBPs were isolated by heparin-affinity chromatography. The recovered HBPs fractions were pooled. One-dimensional sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDSPAGE) 12.5% was performed in vertical minigels. Eight bands with molecular weights ranging from 15 to 63kDa were observed. Two proteins were identified (22 and 25kDa), similar to those previously described in Bos taurus taurus bulls. Other bands identified in this study (39, 53, 58 and 63kDa)... |

| ABSTRACT In order to study and characterize the lesions in the reproductive tract of Nellore heifers naturally infected with Ureaplasma diversum and presenting granular vulvovaginitis syndrome (GVS), fragments of uterine tube, uterus, cervix, vagina and vulva of 20 animals were evaluated. The macroscopic lesions of the vulvovaginal mucosa were classified in scores of “1” mild, until “4”, severe inflammation and pustular or necrotic lesions. The histopathological evaluation was performed using scores of “1” to “4”, according to the inflammatory alterations. The fragments with severe microscopic lesions (3 and 4) were from the uterine tubes and uterus, which showed leukocytes infiltration and destruction and/or necrosis of epithelium. Alterations in the... |
