Abstract
This study aimed to evaluate diagnostic techniques for trypanosomiasis, caused by Trypanosoma vivax, in naturally infected cattle in Minas Gerais, Zona da Mata. The deaths of six lactating cows with similar clinical conditions-characterized by hyporexia, hypogalactia, and recumbency-had been reported from one property. Initially, two animals were examined and diagnosed with trypanosomiasis through identification of the protozoan in a blood smear. After the initial diagnosis, all lactating cows (n=37) on the property were examined, and blood samples were collected for tests including whole blood smear, buffy coat smear, Woo's technique, enzyme-linked immunosorbent assay (ELISA), and polymerase chain reaction (PCR). Woo's test, buffy coat smears, and whole blood smears indicated that 4/37 (10.81%) animals were positive for trypanosomiasis, whereas ELISA and PCR indicated that 33/37 (89.19%) and 27/37 (72.97%) animals, respectively, were positive. The agreement obtained between parasitological techniques was classified as high, while between ELISA and PCR, no agreement. In conclusion, parasitological techniques have a low capacity to identify infected animals in the chronic stage of T. vivax infection. Therefore, techniques such as PCR and/or ELISA should be used to minimize the occurrence of false negatives.

Abstract
ABSTRACT The aim of this study was to assess the vitality and lung function of preterm lambs. Twenty seven preterm lambs were divided in four groups. Group I (n=6) preterm lambs/ control; group II (n=9) lambs born to mothers that were treated with dexamethasone antepartum; group III (n=6) lambs treated with surfactant; and group IV (n=6) lambs treated with surfactant and born to mothers that were treated with dexamethasone antepartum. The APGAR score was performed after birth (T0) and 15 minutes later (T1/4) to assess vitality. The vital signs, blood gas analysis, spirometry and capnometry were assessed immediately after birth and continued until 48 hours. Chest radiographs were performed at T0, T24 and T48. Significant rectal temperature interactions occurred at T1 and T6 depending on the type of treatment used. All animals showed low pH values, which were associated with high pCO2 values and HCO3 -values that increased over time from immediately after birth to two days of age. Higher tidal volume values were observed at T1/4, T1 and T24 when the animals were not treated with surfactant. Capnometry showed significant interactions between treatments at T0. Premature animals showed low vitality and impaired pulmonary function.

Abstract
O objetivo deste trabalho foi avaliar a transferência de imunidade passiva de cabras, que pariram com mastite, para seus respectivos cabritos. Os animais foram distribuídos em dois grupos, a saber: grupo 1 (GI), constituído por cabritos, filhos de cabras sem isolamento microbiológico em ambas as glândulas mamárias, e grupo 2 (GII), composto por cabritos, filhos de cabras com resultado positivo à lactocultura, em pelo menos uma das glândulas mamárias. Foram coletadas amostras de colostro e sangue à parição, bem como às 24 e às 48 horas após o parto/nascimento. O diagnóstico e o monitoramento da mastite nos animais foram realizados por meio do California Mastitis Test (CMT), contagem de células somáticas e isolamento microbiológico. A proteína total foi mensurada pelo método do biureto, e as concentrações de imunoglobulina A (IgA), imunoglobulina G (IgG), transferrina, albumina e haptoglobina por meio da eletrofoerese em gel de poliacrilamida contendo dodecil sulfato de sódio (SDS-PAGE). Os agentes mais isolados na cultura microbiológica foram os Staphylococcus coagulase negativa. Não houve diferença significativa (P<0,05) entre os valores médios de imunoglobulina G (IgG) nos cabritos provenientes de cabras com mastite quando comparados aos recém-nascidos oriundos de cabras livres de infecções intramamárias. Da mesma forma, a atividade de gamaglutamiltransferase (GGT) não mostrou diferença entre os grupos em todos os momentos avaliados. A ingestão de colostro decorrente de cabras com mastite não causou falha na transferência de imunidade passiva nos respectivos conceptos.

Abstract
PURPOSE To assess the cardiorespiratory parametes, recovery, gastrointestinal motility and serum cortisol concentrations in horses anesthetized with isoflurane with or without a continuous rate infusion (CRI) of butorphanol for orchiectomy. METHODS Twelve adult, intact, male horses weighing 332 ± 55 kg were included in the study. Xilazine was administered as premedication. Anesthesia was induced with ketamine and midazolam and maintained with isoflurane. Butorphanol (0.025 mg kg-1 bolus) or an equivalent volume of saline (0.9%) was given intravenously followed by a CRI of butorphanol (BG) (13 µg kg-1 hour-1) or saline (CG). Cardiorespiratory variables were recorded before (T0) and every 15 minutes for 75 minutes after the start of infusion. Serum cortisol concentration was measured at T0 and 60 minutes, and 30 minutes and 19 hours after the horse stood up. Recovery from anesthesia was evaluated using a scoring system. Gastrointestinal motility was evaluated before anesthesia and during 24 hours after recovery. RESULTS There were no significant differences between groups in cardiopulmonary variables, or recovery scores or serum cortisol concentrations. A reduction in gastrointestinal motility was recorded for 60 minutes in BG. CONCLUSIONS Continuous rate infusion of butorphanol in horses anesthetized with isoflurane did not adversely affect the cardiopulmonary variables monitored, or recovery scores. A small but statistically significant reduction in gastrointestinal motility occurred in the butorphanol group.

Abstract
PURPOSE To assess the hemodynamic changes and bispectral index (BIS) following administration of a continuous rate infusion (CRI) of butorphanol in isoflurane-anesthetized calves. METHODS Eight calves weighing 110 ± 12 kg were included in the study. Anesthesia was induced with 5% isoflurane in O2 delivered via face mask and maintained with end-tidal concentration of 1.4%. IPPV was set to a peak inspiratory airway pressure of 15 cmH2O and respiratory rate of six breaths minute-1. Forty minutes after the start of anesthetic maintenance, 0.1 mg kg-1butorphanol was administered intravenously, followed by a CRI of 20 µg kg-1 minute-1. Hemodynamic variables and BIS were recorded before butorphanol administration (T0), and at 10, 20, 40 and 80 minutes following the CRI. Anesthesia was discontinued after the last recording and the calves were allowed to recover. The time to sternal recumbency (SRE) and standing (ST) were evaluated. RESULTS There were no significant differences between the moments in all hemodynamic variables and BIS. The time to SRE and ST was 9 ± 5 and 14 ± 7 minutes, respectively. CONCLUSION The continuous rate infusion did not produce clinically relevant changes in hemodynamic or bispectral index values compared to baseline in mechanically ventilated and unstimulated calves anesthetized at 1.4% isoflurane.

Abstract
Este estudo objetivou avaliar as características do líquido ruminal, hemogasometria, atividade pedométrica e ocorrência laminite subclínica, por meio da presença de enfermidades podais secundárias, em vacas leiteiras de alta produção, provenientes de um rebanho comercial. Foram avaliadas 200 vacas holandesas, oriundas da mesma propriedade, localizada na região de Araçatuba, SP, divididas em quatro grupos, sendo estes estabelecidos a partir da produtividade diária. Inicialmente procedeu-se o exame clínico dos animais, seguido da colheita de amostras do líquido ruminal, por meio de sondagem esofágica, sendo este avaliado quanto ao pH, cor, odor, consistência, sedimentação, flutuação e prova de redução pelo azul de metileno. Também foram colhidas amostras de sangue venoso para hemogasometria, além da coleta dos dados da pedometria (número de passos) e produção de leite diária das vacas. Os dados obtidos foram tabulados e submetidos à análise de correlação. Nenhum animal avaliado apresentou alterações no pH ruminal, bem como não foram encontrados distúrbios do desequilíbrio ácido básico, pois os valores de pH sanguíneo, PCO2, TCO2, HCO3- e EB estavam dentro da normalidade, durante a análise hemogasométrica. A pedometria foi efetiva como método de triagem para as vacas acometidas de afecções podais, pois se observou a redução no número de passos devido à dor, correlacionada a menor produção leiteira. Contudo, a identificação destas afecções, somente foi possível mediante exame clínico específico dos dígitos. A ocorrência das afecções podais em 49,5% do rebanho deveu-se aos fatores de riscos presentes na propriedade, como o concreto abrasivo e instalações inadequadas, associados também a possível ocorrência de acidose ruminal subaguda, não diagnosticada pela metodologia utilizada. A correlação entre os valores do pH ruminal, pedometria e hemogasometria se mostrou eficiente para o diagnóstico precoce das afecções podais e também no estabelecimento da etiologia destas enfermidades. A laminite subclínica acometeu primariamente as vacas do rebanho, considerando a etiologia multifatorial desta afecção, ocorrência e distribuição das enfermidades podais diagnosticadas.
