ABSTRACT

Este estudo teve como objetivo caracterizar a epidemiologia da presença de ácaros hematófagos em granjas de postura no estado de Minas Gerais. Foi utilizado um banco de dados secundário, com informações de 402 galpões de 42 propriedades comerciais. As variáveis utilizadas para compor o modelo de correspondência foram selecionadas por meio do teste qui-quadrado (P≤0,05). Foi construído um índice para a presença de ácaros hematófagos, considerando alguns fatores de risco. Além disso, um estudo da análise espacial foi realizado para avaliar a presença de ácaros hematófagos em Minas Gerais. Observou-se a presença de ácaros hematófagos em 48% dos galpões, sendo a de O. sylviarum de 45,5%, O. bursa de 17,4% e D. gallinae de 2,7%. Houve associação entre o índice de risco com os intervalos de remoção de fezes e com a presença ou a ausência de aves sinantrópicas. Verificou-se que granjas mais tecnificadas não utilizam acaricida em seus galpões. A presença de ácaros hematófagos foi observada na mesorregião Sul/Sudoeste de Minas Gerais e entre as mesorregiões Oeste de Minas e Metropolitana de Belo Horizonte. Esses resultados fornecem conhecimento sobre a epidemiologia desses ectoparasitos e podem contribuir na tomada de decisões, reduzindo os riscos de possíveis infestações em aves de postura.(AU)


This study aimed to characterize the epidemiology of the presence of hematophagous mites in posture farms in the state of Minas Gerais. Was used a secondary database with information from 402 chicken houses in 42 commercial properties. The variables used to compose the correspondence model were selected through chi-square tests (P≤0.05). A risk index was built to the presence of hematophagous mites considering some risk factors. Additionally, a study of the spatial analysis was done to evaluate the presence of hematophagous mites in Minas Gerais. Was observed the presence of hematophagous mites in 48% of chicken houses, the presence of O. sylviarum was 45.5%, O. bursa 17.4% and D. gallinae 2.7%. There was an association between the risk index with the intervals for the removal of manure and the presence or absence of synanthropic birds. It was verified that more technified farms do not use acaricide in their chicken houses. The presence of hematophagous mites was observed in the Messoregions South/Southwest of Minas Gerais and between the West and Metropolitan Mesoregion of Belo Horizonte. These results provide knowledge about the epidemiology of these ectoparasites and may contribute to decision making by reducing the risks of possible infestations in poultry.(AU)

ABSTRACT

Blood pH, carbon dioxide and oxygen partial pressures, bicarbonate, total carbon dioxide, base excess, standard bicarbonate and oxygen saturation concentrations were measured by blood gas analyses in a study of assessment of the acid-base status in young calves. Venous blood samples were taken from 80 healthy female Holstein calves, from four to 30 days of age. The calves were divided in two groups based on the interval between the morning milk feeding and the blood sample collection (up to 30 minutes or over two hours). Greater alkali reserve and higher carbon dioxide pressure values were observed later than 2h after milk feeding, supporting the influence of the diet on the acid-base balance of calves during the milk feeding phase
