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.

    Intoxicação por sal em ovinos e caprinos no estado do Pará
    (Universidade Federal do Pará, 2014-06-30) DUARTE, Marcos Dutra; BARBOSA NETO, José Diomedes; http://lattes.cnpq.br/1516707357889557
    This paper reports the first outbreaks of salt poisoning in sheep and goats in Brazil on a farm in the state of Pará. The evaluation of the facilities and the handling indicates as predisposing factors the excessive intake of mineral mixture and water restriction. The first outbreak occurred in sheep, eight animals (1,46%) were affected from a total of 545 animals and four (50%) of them died. The second and third outbreaks occurred in a herd of 191 goats. In the second outbreak, four animals (2,09) were affected and none died. In the third outbreak, eight goats (4,19%) were affected and two (25%) of them died. In sheep the main clinical signs were recumbency, decrease or absence of cutaneous sensibility, absence of auricular, palpebral and menace reflexes, mydriasis, nystagmus, opisthotonus, spasticity of limbs, somnolence and stupor. Beside this signs observed there were bloat, diarrhea, tachypnea, tachycardia, dehydration and polyuria. The clinical course of the disease in sheep that died ranged from 2 and a half hours to 48 hours. The main clinical signs in the goats were muscle weakness, abnormal posture of the head and neck such us staying with his head down, head and neck rotation, neck extension and lateral deviation of the neck, sternal and lateral recumbency, mydriasis, absence of pupillary reflex to light, stay with pelvic and thoracic limbs abduced or in broad-based, increased flexor reflex, polyuria and intense thirst were observed. They were observed also rumen hypomotility, tachycardia, decreased skin turgor. The clinical course in goats of second outbreak varied from 4 to 24 hours. In the goats of third outbreak who died the evolution ranged by six to eight hours and two to three days in the goats who have recovered. The medium of serum concentration of sodium and potassium of 31 sheep from the same group affected on samples collected during the outbreak revealed hypernatremia (190 mEq/l) and hyperkalemia (8.2 mEq/l), respectively. The mean serum concentrations of sodium and potassium of 36 goats from the same lot of animals affected in the second outbreak in samples taken two days before the onset of clinical signs revealed hypernatremia (167 mEq/l) and the average level of potassium (4.7 mEq/l) within the reference values for the species. The averages of these same parameters in samples from goats in the third outbreak with clinical signs of intoxication (143,7 mEq/l for sodium and 3.9 mEq/l for potassium) were within the reference values. However, the averages of these same parameters in samples of goats in the third outbreak, with clinical signs of intoxication (143.7 mEq/l for sodium and 3.9 mEq/l for potassium), were within the reference values. At necropsy in only one of four sheep there was flattening of the cerebral gyri. Microscopically in this sheep there was a vacuolization of the neuropil in the cerebral cortex with moderate intensity in the intermediary surface and mild on the superficial, with increased of perineural and perivascular spaces. In these areas there was still markedly swollen nucleus of astrocytes and acute neuronal necrosis. Noteworthy macroscopic or microscopic changes were not observed in the goats. The dosages of sodium showed high values in the brain of the poisoning animals, in an ovine value of 3,513 ppm and in two goats, values of 3,703 and 3,675 ppm. Five goats of the third outbreak were treated with dexamethasone and thiamine, intramuscularly, twice daily for two days, and water was offered in small amounts three times a day. All treated animals were recovered in three days. The diagnosis of salt poisoning was based on epidemiology, clinical signs, in the lesions, in the dosages of sodium in serum and brain and in the response to treatment in five goats.

    Prevalência de alterações clínicas e histopatológicas do sistema genital de búfalas (Bubalus bubalis) no Estado do Amapá

    Objecting to find out the prevalence of infertility diseases, 895 buffalo cows were submitted to clinical examination with main emphasis on the gynecological aspects and tuberculosis and brucellosis tests, located in Cutias do Araguari country, Amapá State, and analyzed 1000 genitals slaughtered buffalo cows. The prevalence of tuberculosis and brucellosis on clinical analysis were 9,33 and 9,11% respectively. On 895 clinical examined buffalos cows, 299 (33,41%) were pregnant, 188 (62,88%) on the right horn and 111 (37,12%) on left horn. On the buffalo cows group with some alteration, were discovered the following disorders: a) abnormal ovaries: non-functional ovaries, 75 (8,37%); follicular cysts, 6 (0,67%); b) oviduct abnormalities cases: slight adhesions, 24 (2,9%); severe adhesions, 22 (2,46%); hydrosalpinge, 8 (0,9%); c) uterine and cervical abnormalities cases: slight chronic endometrititis, 5 (0,56%); moderate chronic endometritis, 7 (0,78%); irregular cervix, 14 (2,9%); d) Vaginal and vulvar abnormalities cases: lacerated vulva, 9 (1,1%); totalizing 172 (19,21%) buffalo cows with some abnormalities. On the slaughtered buffalo cows were evidenced 661 (66,10%) of pregnancy buffalo cows, that 86 (8,6%) with some reproductive disorder and 339 (33,90%) not pregnancy buffalo cows with 74 (7,4%) with some reproductive disorder. In 661 pregnancy, 412 (62,3%) were in right horn and 249 (37,7%) on left horn. The reproductive abnormalities found were: a) ovarian abnormalities cases: non-functional ovaries, 16 (1,6%); para-ovarian cysts, 5 (0,5%), epithelial inclusion cysts, 8 (0,8%); follicular cysts, 1 (0,1%); b) oviductal abnormalities cases: hydrosalpinge, 18 (1,8%); tubo-ovarian cysts, 5 (0,5%); slight adhesions, 70 (7,0%); severe adhesions 21 (2,1%); c) uterine and cervical abnormalities: entometritis, 9 (0,9%); perimetritis, 3 (0,3%); adenomiosis, 1 (0,1%); segmental aplasia of uterus, 1 (0,1%); twining, 1 (0,1%); irregular cervix, 1 (0,1%). The major percentage of fetus were found on final third of gestation with 236 (35,65%) cases. Several are the problems that can affect the fertility of buffaloes cows and we need to identify it to solve the problems of productivity.
