| Use of genetic markers can aid on the identification of animals with highest breeding values in beef cattle. The PIT1 gene codes for the Pit-1 transcription factor is essential for the activation of prolactin, growth hormone and PIT1 genes. This research is an investigation of the effect of PIT1-HinfI polymorphism on growth traits of 509 Canchim animals, from two lineages, GG1 and GG2. PIT1 genotypes were identified through PCR-RFLP. Genotype effect on phenotypic values for birth weight (BW), standardized weaning weight (W240), weight at 12 months of age (W365), and the average daily weight gain from birth to weaning (AGBW), and from weaning to 12 months of age (AGW12) were analyzed by the least squares method. Effects of the interaction between the... |

| 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... |

| The efficiency of bohemine and roscovitine in combination with ionomycin on parthenogenetic activation and initial embryonic development of bovine oocytes was studied. Two experiments were performed: in the first, different concentrations (0, 50, 75 or 100µM) and different exposure periods (2, 4 or 6 hours) to bohemine or roscovitine were tested for activation rates of in vitro matured (IVM) bovine oocytes, which were pre-exposed to ionomycin. The best treatments, 75µM bohemine and 50µM roscovitine, both for 6h, were used in the second experiment, in which IVM bovine oocytes were exposed to ionomycin, followed or not by bohemine or roscovitine treatment, and evaluated for nuclear status, activation rate and blastocyst development were assessed. The... |

| The effects of insulin-like growth factor-I (IGF-I) on in vitro maturation (IVM) (experiment I) and on in vitro embryo development (experiment II) of bovine oocytes fertilized in vitro, were evaluated in terms of cleavage (CR), blastocyst (BR) and hatching (HR) rates. For IVM, immature cumulus-oocyte complexes were cultured in TCM-199 medium supplemented with Hepes, sodium bicarbonate, sodium pyruvate, additives, fetal calf serum (B-199 medium) and gonadotropins (14 U/ml PMSG and 7 U/ml hCG). For embryo development, the oocytes/zygotes were cultured in B-199 medium with bovine oviduct epithelial cells in suspension under silicon oil. Treatments for in vitro culture conditions for both experiments were: 1- B-199 + 200 ng/ml IGF-I; 2- B-199 + 100 ng/ml... |

| The aim of this work was to verify the occurrence of bovine and swine cysticercosis in animals slaughtered at the Abatedouro Municipal de Sabáudia, Paraná State. The number of daily-abated animals, the number of animals with cysticercus and the number and location of the cysticercus in the animals in a period of twelve months were collected. From 1046 swines slaughtered none showed cysticercus, but 36/out of 389 bovines (9.3%) were contaminated. Head was the most parasited region, followed by heart, tongue and liver. The absence of contamination observed in swines and the low contamination of the bovines reinforce the efficiency of the control measures accomplished in Paraná State. |

| Squamous metaplasia of rete ovarii is characterized by replacement of the normal cuboidal epithelium of rete ovarii by a keratinized stratified scamous epithelium, leading to accumulation of keratinized material within the tubules and cystic dilatation of rete ovarii. The present study decribes a case of scamous metaplasia of rete ovarii in a 10 year old Zebu cow, including clinical, surgical, ultrasonographic, histopathological and hormonal findings. At first ultrasound examination the cow had lightly asymmetric ovaries with follicles presenting echogenicity similar to luteinized follicular cysts. After transvaginal follicular aspiration creamy yellowish sanguineous-purulent content was recovered. After unilateral ovariectomy the ovary was sectioned and... |

| 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,... |

| The effect of cryopreservation in IFN-tau, from bovine embryos produced in vitro was evaluated. Two treated groups (G1= fresh bovine embryos, n=59 and G2= freezed embryos, n=84) were used to study the effect of cryopreservation on IFN-tau secretion. After reaching the blastocyst phase, the embryos were kept on individual culture for additional period of 7 days. On days 3 and 7 after the beginning of embryos cultivation, samples of the media culture were taken for IFN-tau secretion titration. Oocysts taken from follicles ranging from 3 to 5mm in diameter were obtained from ovaries of females at slaughterhouse. The embryos were frozen, after being dehydrated with ethylene glycol (1.8m), conditioned on 0.5ml palletes and frozen. Frozen embryos secreted lower... |

| The objective of the present study was to determine the sperm enrichment with X-bearing spermatozoa, after one centrifugation in a Percoll or OptiPrep continuous density gradient, using quantitative real-time polymerase chain reaction (qPCR) of sperm DNA and resultant in vitro-produced bovine embryos by PCR. Frozen/thawed sperm was layered on density gradients and the tubes were centrifuged. Supernatants were gently aspirated and the sperm recovered from the bottom of the tubes. Cleavage and blastocyst rates were determined through in vitro production of embryos and PCR was performed to identify the embryos' genetic sex. A difference in blastocyst rate was found in the Percoll treatment compared to OptiPrep (P<0.05). The percentage of female embryos in... |

| ABSTRACT Paratuberculosis is a chronic and incurable disease that affects ruminants and other domestic animals. It is caused by Mycobacterium avium subsp. paratuberculosis (MAP) that may also be involved in some human diseases such as Crohn's disease, type 1 diabetes, sarcoidosis, multiple sclerosis, and Hashimoto's thyroiditis. The objective of this study was to investigate the occurrence of MAP DNA in samples of artisanal coalho cheese purchased in the State of Pernambuco. Forty samples of coalho cheese submitted to the Real Time Polymerase Chain Reaction (qPCR) technique were analyzed for the detection of the MAP region IS900. 11 (27.5%) were positive with a mean of 195.9 MAP colony forming unit (CFU) per gram of each sample, with a minimum of 30.3... |
