Electrocardiographic aspects of singleton pregnancy and neonatal period in American Miniature horse breed

Background: During pregnancy, cardiovascular adaptations occur in order to meet maternal demands and adequate supportfor fetal development, but they are still unclear in the equine species, especially in the American Miniature horse breed.The main hemodynamic changes that occur during pregnancy are increased heart rate, cardiac output, and blood volume.It is necessary to use the reference values for the miniature breeds, in addition to the age range and reproductive condition,so the objective of this study was to evaluate the effect of pregnancy on electrocardiographic (ECG) parameters in maresand also of age in newborns foals of American Miniature horse breed.Materials, Methods & Results: Ten American Miniature Horse mares, between 7 and 19 years old (12.14 ± 4.05 years),116.85 ± 24.09 kg of body weight were used in the experiment. All these mares were pluriparous, with 5.9 ± 3.5 of births,minimum of 2, and maximum of 12 foaling times. They were maintained in common social group in an indoor house stablewith straw bed, with access to an outdoor paddock for several h per day. Twice a day they were fed with hay. Mineral supplements and water were available ad libitum. The ECG were obtained in 10 pregnant mares and in 10 neonates. All femaleswere examined at a representative time of each trimester of pregnancy, at 30, 210, 300 days before and 21 days after delivery.Neonates were examined on different times: first 24 h after delivery, weekly on the 7th, 14th, 21st, 28th and 35th days of age.The ECG parameters considered were the heart rate and rhythm, duration and intervals (P, PR, QRS, QT, T) and amplitude(P, R, S, T) of ECG waves. The mean of pregnancy duration was 319.4 ± 4.97 days. Heart Rate (HR) varied between 51 to59 bpm during pregnancy and 56 bpm on the 21st day after delivery. Comparing the clinical parameters of pregnant mares,non-pregnant mares and foal a difference was found for HR, Respiration Rate (RR) and...

Zoonosis en animales de producción: aspectos generales / Zoonoses in animal production: general aspects / Zoonoses em animais de produção: aspectos gerais

Brasil se ha destacado en la producción animal y en su economía uno de los sectores de más rápido crecimiento en el país y que genera ingresos es la agropecuária, especialmente la producción y el ganado vacuno, cerdos y caballos. Las diferentes especies de animales se ven afectados por muchas enfermedades, entre ellas las zoonosis, como la tuberculosis, la brucelosis, cisticercosis complejo teniasis, toxoplasmosis, leptospirosis y la rabia. En esta revisión, se discuten los aspectos relevantes relacionados con estas enfermedades, con un enfoque en etioepidemiologia, diagnóstico y control. También se discutirá el papel del medico veterinario en la prevención y control y su inclusión en la salud pública, en el que más allá de los aspectos productivos y de bienestar de los animales, es responsable de la seguridad de los productos de origen animal que se ofrecen para el consumo, principalmente por su participación directa en las actividades de inspección de alimentos saludables(AU)

Brazil has excelled in animal production and in its economy one of the fastest growing sectors in the country that generates income is agriculture, especially the production and cattle, pigs and horses. The different animal livestock species are affected by many diseases, among them zoonoses, such as tuberculosis, brucellosis, complex taeniasis cysticercosis, toxoplasmosis, leptospirosis and rabies. In this review, relevant aspects related to these diseases are discussed, with a focus on etioepidemiologia, diagnosis and control. It will also be discussed the role of the veterinarian in the prevention and control and his inclusion in public health, in that beyond the productive aspects and animal welfare, he is responsible for safety of animal products offered for consumption, mainly for his direct involvement in health food inspection activities(AU)

O Brasil tem se destacado na produção animal e na sua economia, sendo que um dos setores que mais cresce e gera renda ao país é a agropecuária, especialmente com a produção e criação de bovinos, suínos e equinos. As diferentes espécies animais de interesse zootécnico são acometidas por inúmeras enfermidades, dentre elas as zoonoses, tais como tuberculose, brucelose, complexo teníase-cisticercose, toxoplasmose, leptospirose e raiva. Nesta revisão, são abordados aspectos relevantes referentes a essas enfermidades, com enfoque na etioepidemiologia, diagnóstico e controle. Será discutido ainda o papel do médico veterinário na prevenção e controle e sua inserção na saúde pública, na medida em que, além dos aspectos produtivos e do bem estar animal, ele é responsável pela inocuidade dos produtos de origem animal oferecidos para consumo, principalmente pelo seu envolvimento direto nas atividades de inspeção sanitária de alimentos(AU)
