O deslocamento dorsal de palato mole (DDPM) ocorre quando o palato se desloca dorsalmente à epiglote. Em equinos, a causa é multifatorial e na maioria das vezes ocorre por disfunção neuromuscular da faringe, que controla entre outras estruturas, o palato mole. Este fator pode ser desencadeado por diferentes enfermidades, e entre elas a Mieloencefalite Protozoária Equina (EPM) ganha destaque, doença causada por um protozoário. O DDPM ocorre comumente de forma intermitente e raramente permanente. O palato consiste em uma estrutura de mucosa oral que realiza a vedação aérea entre a orofaringe e nasofaringe durante a respiração, localizando anatomicamente ventral a epiglote. Durante a deglutição ocorre a movimentação do palato dorsalmente a epiglote para passagem do bolo alimentar e saliva para o esôfago e retorna a sua posição normal em seguida. Caso o palato não retorne à posição ventral, é considerado que o animal possui deslocamento dorsal de palato mole. Este deslocamento acarreta no estreitamento das vias aéreas superiores, responsáveis pelos principais sinais clínicos apresentados pelos animais acometidos. O diagnóstico se baseia nos sinais clínicos e é confirmado através da endoscopia. O tratamento pode ser conservativo ou cirúrgico, dependendo da sintomatologia e conduta do Médico Veterinário. O objetivo deste trabalho é relatar o caso de um equino que apresentou deslocamento dorsal de palato mole (DDPM) persistente secundário a mieloencefalite protozoária equina (EPM).

The aim of the current study was to investigate the effects of using supplementation with commercial core homeopathic during pregnancy and early lactation on 18 pregnant Santa Ines ewes presenting body condition score ≤ 2.5. Pregnant animals were randomly divided in two groups; one was used as control (control group) and the other was supplemented on a daily basis with 30 g of homeopathic product with Natrum muriaticum 10-60, Calcium carbonicum 10-30, Silicea terra 10-400 and Hypothalamus 10-30 per animal, mixed to the concentrate during pregnancy and early lactation (treatment group). The Total Protein (TP) and globulin (GLB) values found in ewes and lambs belonging to the treatment group were higher than and different from those recorded for the control group. The serum albumin (ALB) concentration did not differ between groups of ewes but was different in lambs. TP and GLB evolution in lambs and ewes throughout the seven experimental days showed the animals in the treatment group trend to present higher TP and GLB values in all experimental periods; supplemented animals showed trend to progressive increase in both variables until day 3; whereas nonsupplemented animals showed such trend until day 2 (when they reached their peak). The commercial core homeopathic to the animals during pregnancy and early lactation resulted in higher TP and GLB concentrations in the serum samples collected from ewes and lambs.

Background:Actinobacillosis in adult horses is rare, and is often associated with infection due to Actinobacillus equuli subsp. equuli, which is a commensal organism inhabiting the oral cavity of healthy animals. It is an opportunistic pathogen, and the infection usually occurs secondary to another primary disease or due to predisposing factors such as pre-existing lesions, mainly in the oral cavity. Infection may be associated with peritonitis, bacterial endocarditis, pneumonia, enteritis, infectious periorchitis, abortion, and septicemia. This paper aims to describe the clinical, microbiological, and pathological aspects of actinobacillosis in the oral cavity of a horse.Case:A case of actinobacillosis has been reported in a 22-year-old gelding Quarter Horse. According to the owner, the animal presented with progressive weight loss during the previous three months, and leakage of food from the oral cavity. Examination of the oral cavity revealed sharp enamel overgrowths, which had been corrected during a previous dental procedure. However, five days after the procedure, the animal developed halitosis. Ceftiofur sodium (4.4 mg/kg intramuscularly, every 24 h) was prescribed; two days after the commencement of antimicrobial therapy, the animal presented with sialorrhea, bilateral submandibular lymphadenomegaly, protrusion of the tongue, edema of the base of the tongue, cheeks, and gums, in addition to black-colored sores and scales in the oral mucosa, particularly affecting the base of the tongue and gums. Samples from ulcerative lesions found at the base of the tongue and gums were collected using sterile swabs, and culture and antibiogram were requested. Microbiological culture led to the growth of small colonies measuring less than 5 mm in diameter, that were non-hemolytic, slightly whitish in color but non-opaque, smooth and bright in appearance. These were identified as gram-negative rods on microscopy, and further characterized as Actinobacillus equuli subsp. equuli based on the phenotypic and biochemical findings. The antibiogram revealed sensitivity of the organisms to cephalothin and doxycycline, intermediate sensitivity to amoxicillin, and resistance to florfenicol, metronidazole, clindamycin, and sulfazotrim. The complete blood count revealed anemia with a reduction in hemoglobin (10.1 g/dL) and hematocrit (27.9%), neutrophilia (10.670 x 10³ /mm³), and lymphopenia (330 x 10³ /mm³). Decrease in serum albumin (2.0 g/dL) and alkaline phosphatase (91 IU/L), and increase in globulin (4.9 g/dL), aspartate aminotransferase (361 4 IU/L), and urea (123.8 mg/dL) were noted on biochemical analyses. Two days after the onset of acute clinical signs, the animal died; necropsy revealed severe, subacute, fibronecrotic glossitis associated with myriads of basophilic bacteria.Discussion:This report describes an infection of the oral cavity by Actinobacillus equuli subsp. equuli following a dental procedure, a finding compatible with the opportunistic nature of these bacteria. The presence of enamel overgrowths resulted in the formation of traumatic lesions on the oral mucosa and tongue that favored colonization of the bacteria. The case of equine glossitis reported in this study had a similar clinical presentation to the classic actinobacillosis in cattle, also known as “wooden tongue”, an infection caused by Actinobacillus lignieresii; common symptoms in cattle include oral edema, sialorrhea, and dysphagia.

Avaliou-se a taxa de gestacao, circunferencia dos corpos luteos e formacao de corpos luteos acessorio (CLA) em novilhas da raca Nelore, tratadas com Gonadotrofina Corionica Humana (hCG) sete dias apos inseminacao artificial em tempo fixo (IATF). Foram utilizadas 137 novilhas, com peso medio de 308,07±12,86 kg, distribuidas aleatoriamente em dois Grupos, sendo o Grupo A composto por 67 novilhas que receberam hCG sete dias apos a IATF e o Grupo B de 70 novilhas que receberam solucao salina sete dias apos a IATF. As sincronizacoes da onda folicular e ovulacao foram realizadas pela manha (8h00) e tarde (14h00) respectivamente para os Grupos A e B. No Dia 10 (D10), 48 horas apos a retirada dos implantes vaginais, as novilhas dos Grupos A e B foram inseminadas pela manha e tarde, respectivamente. No Dia 17 (D17), pela manha nos animais do Grupo A, foram aplicados por via intramuscular 1500UI (1,5mL) de hCG e a tarde 1,5mL de solucao salina nos animais do Grupo B. Apos 11 dias (D28), por ultra-sonografia transretal, foi avaliada a existencia, o numero e a circunferencia dos corpos luteos presentes nos ovarios das novilhas dos Grupos A e B. O diagnostico de gestacao foi realizado 35 dias apos a IATF (D45). A aplicacao de hCG em novilhas sete dias apos a IATF induziu a formacao de CLA, nao interferiu na circunferencia dos corpos luteos observados nas femeas gestantes tratadas e nao tratadas e nao melhorou a taxa de gestacao das referidas femeas.

No Brasil predomina o regime de criação extensiva na pecuária de corte, utilizando o “rodeio”, ato de reunir os animais num local pré-determinado no pasto, como manejo comum nesse sistema, sendo executado com intervalos médios de duas a três vezes por semana. Este trabalho teve como objetivo, avaliar e comparar o efeito do manejo diário, “rodeio”, de fêmeas mantidas em estação de monta, em relação ao manejo tradicional realizado na pecuária de corte em regime extensivo, sobre a taxa de gestação de fêmeas da raça Nelore. Foram utilizadas 196 fêmeas contemporâneas, sendo divididas em dois tratamentos: Rodeio diário, 98 fêmeas mantidas em estação de monta com rodeio diário e Manejo tradicional, 98 fêmeas mantidas em estação de monta com rodeio tradicional. Utilizou-se proporção de touro:vaca 1:33 nos dois tratamentos durante estação reprodutiva de 120 dias. Os reprodutores passaram por avaliação andrológica, estavam aptos à reprodução no inicio e final do experimento. O diagnóstico de gestação nas fêmeas foi realizado por palpação transretal 90 dias após o término da estação de monta devido à logística da propriedade. Observou-se que as fêmeas submetidas ao manejo diário obtiveram maior taxa de gestação (84,7%) em relação às fêmeas que foram submetidas ao manejo tradicional (72,4%), obtendo-se aumento de 12,2% na taxa de gestação, demonstrando que a realização de rodeio diário promove incremento da taxa de prenhez na estação reprodutiva.

Two Pool Dorset adult males and 75 mixed-breed prepubertal ewe lambs (average of 179 days-old and 30.0 kg) were used. The females were randomly assigned to three different groups. In the first group the females were submitted to the insertion of intravaginal sponges containing MAP (60 mg) for 12 days and were then biostimulated for eight weeks. In the second group the females were submitted to a single injection of LAP (225 mg) and then to biostimulation for eight weeks. In the last group, the females were only submitted to biostimulation for eight weeks. Animals were considered cyclic when plasma progesterone (P4) concentration exceeded 1.0 ng/mL in at least one of two consecutive blood samples taken within a 7-day interval in three distinct experimental moments. After treatments 93.3% of the females disregarding their group started their cyclicity and most of them (92.0%), continued to be cyclic after 63 days of either MAP or LAP together with biostimulation under both male and female effect. We conclude that prepubertal ewe lambs when submitted to protocols of either MAP or LAP followed by biostimulation result in puberty at the 7 month of age. It can be deducted that some ewe lambs submitted to the administration of either MAP or LAP together with biostimulation promoted a multiplier effect upon the other young females that were then stimulated to start cyclicity.

Foram utilizados dois machos adultos Pool Dorset e 75 borregas sem raça definida com idade entre 154 e 218 dias, (média de 179 e erro padrão ± 1,20 dias) e peso entre 25,8 e 36,9kg (média de 30,0kg e erro padrão ± 0,124kg) no início do experimento que foram divididas equitativamente quanto ao peso, escore de condição corporal e índice de massa corpórea, em três grupos (grupo Bioestimulado, MAPesp e P4LA) de 25 animais. No grupo bioestimulado as fêmeas foram submetidas à bioestimulação por oito semanas, no grupo MAPesp as fêmeas foram submetidas por 12 dias a esponjas intravaginais impregnadas de medroxiprogesterona (60mg) e bioestimulação por oito semanas e no grupo P4LA as fêmeas foram submetidas à única aplicação de progesterona de longa ação (225mg) e bioestimulação por oito semanas. O experimento foi composto por 10 observações ao longo de 82 dias. Em 3 momentos experimentais foram realizadas coletas de sangue pareadas em sete dias para dosagem plasmática de progesterona. Em nove observações foram realizadas biometrias envolvendo aferições de peso, índice de massa corpórea e escore de condição corporal. Conclui-se que 93,3% das fêmeas dos três grupos iniciaram a ciclicidade no momento experimental 1 e a maioria, 92% das borregas, permaneceu ciclando após 63 dias da administração exógena de acetato de medroxiprogesterona ou progesterona de longa ação e bioestimulação pelos efeitos macho e fêmea. The aim of this study was to evaluate the answer of ewe lambs to exogenous administration of either medroxyprogesterone acetate or long action progesterone associated to bioestimulation in prepuberty. Two Pool Dorset adult males and 75 mixed-breed ewe lambs were used with the average age of 179 days and average weight of 30.0kg in the beginning of the experiment. The females were divided into three different groups (Group MAP, LAP4 and Bioestimulated) according to their bodyweight, body condition score (BCS) and body mass index (BMI). There were 25 animals in each group. In the MAP group the females were submitted to intravaginal sponges containing medroxyprogesterone acetate-MAP (60mg) for 12 days and were bioestimulated for eight weeks.In the LAP4 group the females were submitted to a single application of long action progesterone (225mg) and bioestimulation for eight weeks. And in the Bioestimulated group the females were submitted to bioestimulation for eight weeks. Animals were considered cycling when progesterone concentration reached ≥1.0ng/mL in two consecutive samples taken 7days distant from one another in 3 experimental moments. After the treatments, 93.3% of the females disregarding their group began the cyclicit and most of them ( 92.0%),continued cyclic after 63 days of either MAP or long action progesterone and bioestimulation under both male and female effect.

In order to enhance the use of biotechnology in females it is necessary to have good knowledge of the ovarian events, and thus enable the manipulation of the estrus cycle to concentrate ovulations in an established period of time. In this experiment, we evaluated the ovary response and corpus luteum (CL) parameters in a short-duration protocol associated or not to lecirelin (L)(GnRH) and/or estradiol benzoate (EB). Twenty-four cyclic Santa InÊs ewes were divided into 4 groups: Control animals (G1; n = 6) received 45 μg of d-cloprostenol (Prolise®, Tecnopec, Sao Paulo, Brazil) on Day 0. Intravaginal sponges containing medroxyprogesterone acetate (MAP60®, Tecnopec) were inserted on Day 3. Then on Day 7 sponges were removed and 400 IU of eCG and 45 μg of d-cloprostenol were administered. G2 (n = 6) animals underwent the same protocol as G1 but with administration of 1 mg of EB on Day 1; G3 (n = 6) animals underwent the same protocol as G1 but with administration of 25 μg of L (Gestran plus®, Tecnopec) 30 h after sponge withdrawal; G4 (n = 6) animals underwent the same protocol as G1 but with administration of 1 mg of EB on Day 1 and 25 μg of L 30 h after sponge withdrawal. Ewe ovaries were assessed via transrectal ultrasound (US), and CL were measured 4 days after ovulation. On the same day blood samples were taken to measure plasma progesterone levels via radioimmunoassay. Twenty-three out of 24 animals ovulated. One ewe from G4 that did not ovulate was taken out of the experiment. The average size of the largest pre-ovulatory follicle was 7.3 mm (G1), 7.0 mm (G2), 6.8 mm (G3), and 7.4 mm (G4) (P > 0.05). There were 1.8, 1.2, 2.0, and 1.4 ovulated follicles per animal in G1, G2, G3, and G4, respectively. The results for estrus start and duration after sponge withdrawal were G1: 32/38.6; G2: 37/69.3; G3: 29.3/37.3; G4: 44/68 h, respectively. Ovulation time span was G1: 65.3; G2: 88; G3: 53.3; G4: 82.4 h after sponge withdrawal. There was a high correlation of ovary mensuration and progesterone level (r = 0.64; P < 0.0001) on the fourth day after ovulation. Progesterone levels after ovulation were 2.37 ng mL-1 (G1); 1.5 ng mL-1 (G2); 3.22 ng mL-1 (G3) and 1.99 ng mL-1 (G4), being higher in G3 than in G2 (P < 0.05). It was seen that the EB is prejudicial to the CL function. Despite the fact that there was no significant difference of progesterone levels within G1, G3, and G4, animals in G3 displayed higher levels of progesterone; hence, there is a need for further studies using a larger number of animals and fertility test.
