Resumo
Este estudo tem como foco a comparação do parasitismo gastrointestinal de dois grupos de equinos com aptidão para a disciplina de saltos de obstáculos, sendo estes, equinos estabulados e equinos a campo, e estando inseridos na zona da grande Lisboa. A estes animais tinham sido administrados antiparasitários seis meses antes do estudo.
O parasitismo pode estar relacionado com a perda de condição corporal e de performance de alguns equinos, podendo ter relacionamento com a idade ou sexo.
A amostra composta por 60 equinos, 30 estabulados e 30 a campo, teve em si animais de diversas raças, com idades compreendidas entre os 4 e os 20 anos. O sexo predominante foi o masculino; porém, os equinos do sexo masculino foram divididos em castrados e garanhões. Este estudo foi realizado num espaço de um mês, em que foi realizada uma análise fecal a cada individuo do estudo. Cada amostra foi submetida a técnicas qualitativas de flutuação e sedimentação simples e à técnica quantitativa de McMaster.
Observou-se que o número de animais parasitados na amostra era de 58,3%, pela técnica de flutuação, sendo que no grupo de equinos estabulados era de 23,3% e nos equinos a campo era de 93,3%. Durante a avaliação coprológica, verificou-se que os ovos detetados eram de estrôngilos. Nesta dissertação podemos também verificar que a condição corporal e os antiparasitários usados podem estar relacionados com o parasitismo do seu sujeito, tendo sempre em conta o ambiente onde habita.
Palavras-chave: equinos estabulados, equinos a campo, técnica de flutuação, técnica de sedimentação, técnica de McMaster, estrôngilos.
This study focuses on the comparison of the gastrointestinal parasitism of two groups of horses with aptitude for the discipline of show jumping, being these stabled horses and field horses, and being inserted in the metropolitan area of Lisbon. These animals had been dewormed six months before the study. Parasitism may be related to the loss of body condition and performance of some horses and may be related to age or sex. The study consisted of 60 horses, 30 stabled and 30 in the field, had animals of different breeds and aged between 4 and 20 years old. The predominant sex was male; however, males were divided into castrated and stallions. This study was conducted within a month, during which a fecal analysis was performed for each study subject. Each sample was subjected to qualitative fluctuation and simple sedimentation techniques and to a quantitative McMaster technique. It was observed that the number of parasitized cases in the sample was 58.3%, using the fluctuation technique, whereas in the group of stabled horses it was 23.3% and in the horses in the field it was 93.3%, which was confirmed by the McMaster technique. Only strongyle eggs were observed. In this dissertation we can also verify that the body condition and the dewormers used may be related to the parasitism of its subject, always considering the environment where it lives in. Keywords: Stabled horses, field horses, fluctuation technique, sedimentation technique, McMaster technique, strongyles.
