Resumo
Os parâmetros fisiológicos, hematológicos e bioquímicos são ferramentas essenciais para avaliação da saúde dos equídeos, sendo necessário entender os fatores que podem influenciá-los durante a interpretação clínica. Desta forma, objetivou-se com o presente estudo definir os parâmetros fisiológicos, hematológicos e bioquímico-séricos de pôneis hígidos e compará-los com os valores de referência utilizados para a espécie equina, a fim de determinar se é possível utilizar os valores de referência de cavalos no atendimento clínico de pôneis. Foram utilizados 48 pôneis hígidos, divididos em três grupos: Grupo 1 (G1), composto por pôneis machos e fêmeas em crescimento de 1 a 3 anos (n = 4); Grupo 2, composto por pôneis machos (inteiros e castrados) e fêmeas vazias de 4 a 10 anos (n = 35) e Grupo 3 (G3), composto por pôneis fêmeas prenhes e em lactação (n = 9). Foram realizadas avaliações dos parâmetros fisiológicos, como frequência cardíaca (FC), respiratória (FR) e temperatura retal (TR) e foram colhidas amostras de sangue para realização do hemograma e perfil bioquímico. Os pôneis do G1 apresentaram FC significativamente maior que a dos pôneis do G2 e G3, enquanto que os pôneis do G3 apresentaram menor TR que a dos demais grupos. Não houve diferença significativa no hemograma entre os grupos, mas houve correlação negativa (r = -0,81) entre a contagens de neutrófilos e linfócitos. Houve diferença significativa na atividade sérica da fosfatase alcalina (FA), e nas concentrações séricas de bilirrubina total (BT), direta (BD), e indireta (BI), proteína total (PT), globulinas e glicose entre os pôneis do G1 e do G3, quando comparado aos pôneis do G2. Concluiu-se que as variáveis hematológicas e a maioria das variáveis bioquímicas dos pôneis permaneceram dentro dos limites de referência que são utilizados para cavalos, podendo, portanto, adotar tais valores como base de comparação. No entanto, mais estudos necessitam ser realizados para determinar, com maior precisão, os valores de referência destes animais, pois a categoria e fase fisiológica dos pôneis influenciaram em alguns parâmetros fisiológicos e bioquímicos.
- Physiological, hematological and biochemical parameters are essential tools for assessing equine health, and it is necessary to understand which factors can influence them during clinical interpretation. Thus, the aim of this study was to define the physiological, hematological and biochemical serum parameters of healthy ponies and compare them with the reference values used for horses, and to determine if it is possible to use the reference values of horses in clinical care of ponies 48 healthy ponies were used, divided into three groups: Group 1 (G1), composed of male and female ponies growing from 1 to 3 years (n = 4); Group 2, composed of male ponies (intact and castrated) and empty female ponies aged 4 to 10 years (n = 35) and Group 3 (G3), composed of pregnant and lactating female ponies (n = 9). Estimates of physiological parameters such as heart rate (HR), respiratory rate (RR) and rectal temperature (TR) were performed, and blood samples were collected for complete blood count and biochemical profile. The G1 ponies had a significantly higher HR than the G2 and G3 ponies, while the G3 ponies had a lower TR than the other groups. There was no significant difference in blood count between groups, but there was a negative correlation (r = -0.81) between neutrophils and lymphocytes. There was a significant difference in serum alkaline phosphatase activity (AP) and serum concentrations of total bilirubin (BT), direct (BD) and indirect (BI), total protein (PT), globulins and glucose between ponies from G1 and G3, when compared to the G2 ponies. It was concluded that the hematological variables and most of the biochemical variables of the ponies remained within the reference limits that are used for horses, allowing, therefore, to adopt such values as a basis for comparison. However, more studies will be carried out to determine, with greater precision, the reference values of these animals, since the category and the physiological phase of the ponies influenced some physiological and biochemical parameters
