O Programa de Pós-Graduação em Ciência Animal (PPGCAN) é um programa do Campus Universitário de Castanhal (CCAST) da Universidade Federal do Pará (UFPA), Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) e Universidade Federal Rural da Amazônia (UFRA). O Programa iniciou o nível de Mestrado em 1999 junto à CAPES/MEC, tendo aprovação de sua proposta de Doutorado junto à agência em 2008, com início da primeira turma em 2009, o que certamente contribuirá à formação de massa crítica regional.Se caracteriza por apresentar um conjunto de disciplinas que repassam aos alunos um embasamento teórico e prático, capacitando os mesmos a aplicarem os conhecimentos adquiridos no avanço regional da produção animal. Direcionando as linhas de pesquisa do curso à nutrição, biotecnologia, pastagens, conservação de recursos genéticos, reprodução, sanidade animal, bovinocultura, bubalinocultura, animais silvestres, ecologia aquática e aquicultura.

    This paper describes the epidemiological, clinical, pathological and bacteriological the first periodontitis record in sheep in Brazil occurred in a rural property in the municipality of Benevides, Para. The outbreak occurred about a month after grazing in the area of Panicum maximum cv. Massai, which suffered agricultural practices, there was swelling in the jaw in a few animals, mostly those over the age of 36 months. The extraoral examination was performed in 545 sheep and there was swelling of the jaw in 3.7% of them. Clinical signs were low body score, rough hair coat and dull, some relaxation and loss of premolars and upper and lower molar teeth, abscess and fistula formation in the affected site, demonstration of pain on palpation and difficulty chewing. Between the 39 heads of young animals analyzed in the post-mortem examination, 51.3% had lesions somewhere and between the 38 analyzed after maceration, 73.7% also had injuries. 45% of the lesions from the 39 heads were in the maxilla, 15% in the mandible and 40% in both structures (maxilla and mandible) and from those heads with injuries observed after maceration 50% of the lesions were in the maxilla and 50% in the maxilla and mandible. Between the 17 heads of adult animals analyzed in the post-mortem examination and after maceration all had lesions somewhere. In the post-mortem examination, 11.8% had lesions in the mandible and 88.2% in both structures; after maceration, 5.9% were in the maxilla, 11.8% in the mandible and 82.3% in both structures. The histopathological findings revealed a chronic pyogranulomatous inflammatory process. To characterize the subgingival microbiota of the 14 sheep with periodontitis it was performed the Polymerase Chain Reaction (PCR), especially for microorganisms belonging to the red complex Socransky (Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola) and other possible Gram-negative and Gram-positive periodontopathogens. There were identified in 50% of the samples Porphyromonas gingivalis, Tannerella forsythia in 92.8% and Treponema denticola in 78.5%. The three periodontal pathogens belonging to the red complex occurred simultaneously in 42.8% of the samples. We also identified in at least one of the examined animals Campylobacter rectus, Eikenella corrodens, Enterococcus faecium, Fusobacterium nucleatum, Prevotella intermedia, Prevotella nigrescens, and Prevotella loeschii. In the 14 samples Aggregatibacter actinomycetemcomitans, Dialister pneumosintes, Enterococcus faecalis and Porphyromonas gulae were not detected. The results showed that the sheep periodontitis occurred in the municipality of Benevides - PA has an infectious etiology and rushed a significant number of animals, many with bulging of the jaw; had high incidence in young and involved all of the adult animals post-mortem and after maceration examined.

    Prospecção de biocida em plantas amazônicas e exóticas, visando seu uso racional
    (Universidade Federal do Pará, 2009-02-19) DANTAS, Eneida Pontes Mota; SOUZA FILHO, Antonio Pedro da Silva; http://lattes.cnpq.br/1691897760012496
    The main method of controlling the cattle tick Boophilus microplus is the use of chemical acaricides during the parasite phase. However, the intense use of this method is causing economic damage and promoting the rapid selection of resistant ticks. Besides the risk of residues in milk, in meat and environmental contamination. Within this context, the use of herbal points out as an alternative to control the tick and can reduce the economic and environmental impacts of the use of synthetic chemicals. On this way, the purpose of this study was to evaluate "in vitro" the effect of essential oils of grass-salsa (Cymbopogon winteranius Jowitt) and priprioca (Cyperus articulatus L.), chemicals isolated substances from timbó (Derris nicou; Derris urucu): rotenone, rotenolone and degueline and Andiroba’s oil (Carapa guianensis Aublet.) and neem (Azadirachta indica A. Juss.) in the control of ticks. The searches were conducted on the premises of the Animal Research Unit "Sen. Álvaro Adolpho, of "the Brazilian Enterprise for Agricultural Research - Embrapa Eastern Amazon, in the city of Belém, state of Pará, in the period from March to July of 2008. The engorged females of Boophilus microplus were collected manually, from naturally infected cattle on private property located within an hour of Belém. After collection, they were transported to the laboratory in plastic containers, marked, cleaned and aerated. In the laboratory, they were rinsed in running water, dried on absorbent paper and weighed on analytical balance (accuracy of 0.0001 g). The methodology used was the immersion of teleogines by time of five minutes. After soaking, the ticks were dried on absorbent paper, set in petri dishes and kept at room temperature for completion of the posture. Throughout the trial period the temperature and relative humidity was measured in the laboratory using a termohigrometer. The experimental design used was completely randomized. The percentage of mortality of engorged females of B. microplus, on 5 and 15, varied: 45% to 90%, 37% to 90% and 60 to 90%, 60% to 90% for grass-salsa and priprioca respectively. The results for the stance showed no statistical difference between the concentrations 2% and 10% on the control (water + ethanol). However, there was a difference in the concentration 50% for both grass-salsa as priprioca. For grass-salsa, this concentration was observed egg laying infertile. Regarding the percentage of efficiency of the product, the values obtained were: 100%; 95.63%, 98.77%, 100% and 99,30%, 96,97%, 99,85% and 100% to the effects of essential oil of salsa and grass-priprioca concentrations 2%, 5%, 10%, 50%, respectively. Mortality rates, on the 5th , ranged from 37% to 41%, 49% to 64% and 52% to 41% for rotenone, rotenolone and degueline from low to high concentration, respectively. All substances tested showed significantly higher mortality rate than those obtained by the control group (water + ethanol). The best results were posture of percentage of 49% and 26% for the rotenone degueline and 200ppm, respectively and 34% for rotenolone at 100ppm. The percentage of efficiency in tests with rotenone were 95.24% and 98.68% for rotenolone the order of 97.29%, 98.08%, 100% and degueline 95.45%, 98.23% and 100 %, from 100ppm, 200ppm and 300ppm, respectively. To andiroba and neem, the percentage of mortality was observed on 15 and has a natural behavior of the life cycle of ticks because there was no statistical difference between the control (water + ethanol) and treatments in different concentrations. To andiroba and neem the higher efficiency obtained was 98,01% and 100%, at concentration 50%, respectively.
