Degenerative progressive hereditary mieloencefalopathy is a disease described in young Brown Swiss cattle. In these animals the disease occurs in calves between six months and two years old showing mainly neurological signs. Two Zebu Gir calves were examined at the Veterinary Hospital of Uberaba, both with balance deficits. The neurological examination has shown that they were mentally alert, with appropriate conscience, head tremor, normal sensitive reflexes, normal sensitivity for superficial and deep pain, motor deficit of the pelvic limbs with severe ataxia. The calves were sacrificed. Based on the clinical case and necroscopic and histopathological findings, it could be suggested that the neuropathy, which affected both animals described above, is... |

Seventy-six naturally infected bovines, males and females of mixed breed, aged 8 to 12 months-old, were necropsied. The results of necropsy revealed the presence of 9 helminth genera and 16 species, with the following prevalence and mean infection intensity: Haemonchus placei (100.0%; 3895.5); Haemonchus similis (29.0%; 159.6); Cooperia punctata (100.0%; 5595.0); Cooperia spatulata (32.9%; 137.8); Cooperia pectinata (34.2%; 1010.5); Trichostrongylus axei (69.7%; 239.2); Trichostrongylus colubriformis (10.5%; 10.8); Trichostrongylus longyspicularis (2.6%; 0.5); Ostertagia ostertagi (2.6%; 3.1); Ostertagia lyrata (2.6%; 1.5); Ostertagia trifurcata (1.3%; 0.3); Oesophagostomum radiatum (94.7%; 470.9); Trichuris discolor (47.4%; 32.5); Strongyloides papillosus... |

ABSTRACT: Congenital malformations are functional and structural changes in organ systems, tissues, or organs that may develop during the embryonic or fetal phase. Spinal cord malformations, such as segmental hypoplasia of the spinal cord (SHSC) and syringomyelia, are rare in bovines. A Girolando calf from Valença, Rio de Janeiro, was admitted to the Veterinary Hospital of Universidade Federal Rural do Rio de Janeiro because of motor incoordination. Clinical evaluation revealed a 5-cm depression area in the spine at the dorsal line of the thoracic region. Neurological examination revealed reduced proprioception, pelvic limb extension with increased nociceptive activity, and reduced anal reflex. In radiographic examination, the body of the T11 vertebra had... |

The viability of a formulation of the fungus Monacrosporium thaumasium associated with ivermectin was evaluated for the biological control of bovine gastrointestinal nematode parasites. Four groups of five calves each were placed in pastures with a stocking rate of 1.6 animal/hectare. In group 1 (control), the calves did not receive any treatment. In group 2, each animal received 20g of pellets of M. thaumasium orally twice a week during a six-month period that began with the onset of the rainy season (October 23, 2000). In group 3, each animal received 20g of pellets of M. thaumasium orally twice a week during the same period as 2, as well as two strategic treatments with ivermectin (200 mcg/kg) on May 10, 2001 and July 5, 2001. In group 4, the animals... |

The objective of this study was to determine the effects of vacuum-cooled liquid nitrogen on the development of vitrified immature (germinal vesicle stage; GV) and mature (metaphase II; MII) bovine oocytes after re-warming. Liquid nitrogen was exposed to either atmospheric pressure or to a vacuum (300mm Hg for 45sec); the latter decreased the temperature of the liquid nitrogen to -200°C. Partially denuded oocytes were vitrified either just after selection (GV) or after 22 hours of in vitro maturation (MII) in TCM 199 medium + 10% of estrous mare serum. For vitrification, oocytes were firstly exposed to an intermediate solution (10% EG + 10% DMSO) for 30sec, followed by the vitrification solution (20% EG + 20% DMSO + 0.5M sucrose) for 20sec. Groups of three... |

ABSTRACT: Cattle have extensive paranasal sinuses that are susceptible to disease, most commonly sinusitis. The sinuscopy can be used to evaluate these structures, although there are no descriptions of this region for endoscopic anatomy, especially regarding the trocar position and the most appropriate type of endoscope. This study aimed to standardize the surgical approaches to sinuscopy in cattle by comparing the use of three endoscopes. Four accesses by trephination (one hole for each of the maxillary and frontal sinuses) were made in eight heads of slaughtered cattle. Each hole was inspected with three endoscopes: a 10mm flexible colonoscope with up to 180º of angulation, a 10mm 0° laparoscope and a 4mm 30º arthroscope. It was observed that all regions... |

This study reports an unusual case of deforming mandibular osteomyelitis in a cow caused by Trueperella (Arcanobacterium) pyogenes, on the face of the ventrolateral caudal portion of the right branch of the mandible. Fragment aspired of lesion by fine needle allowed cytological characterization, isolation and identification of T. pyogenes. Radiographic examination showed marked periosteal reaction in the right mandible, numerous lytic areas and cortical bone destruction. Despite of treatment based on in vitro antimicrobial sensitivity test, it was recommended the euthanasia due to progressive worsening of the cow's condition. Multiple abscesses were observed in the mandibular region at necropsy. Pyogranuloma was characterized in histological exam. Sampled... |

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... |
