RESUMO:Este estudo objetivou avaliar as variações hematológicas e bioquímicas que ocorrem em diferentes protocolos de exercícios em equinos de salto. Foram utilizados 17 equinos da raça de salto Brasileiro de Hipismo, entre 5 e 12 anos. Todos os animais foram submetidos aos seguintes protocolos de exercício: repouso (controle); esteira ergométrica (40 min a 5 m/s); treinamento montado (40 min, sendo 10 min ao passo, 20 min ao trote, 10 min ao galope); e competição (prova de salto a 350 m/min, obstáculos com 1,20 m de altura e percurso de 430 m). Foram realizadas coletas de sangue e verificação da frequência cardíaca com os animais em repouso (controle) e imediatamente após o término dos protocolos de exercício. As avaliações sanguíneas abrangeram contagem de eritrócitos e leucócitos totais, hematócrito, concentração de hemoglobina, proteínas plasmáticas totais, creatina quinase (CK), lactato desidrogenase (LDH), aspartato transaminase (AST), fosfatase alcalina (FA), lactato, glicose, bicarbonato, ureia, creatinina, sódio e potássio. Em relação ao grupo controle, o exercício em esteira ergométrica apresentou variações significativas apenas em hematócrito, frequência cardíaca, potássio e creatinina. O treinamento montado e a competição apresentaram aumentos nas concentrações de proteína, CK, LDH, FA e potássio com relação aos demais protocolos de exercício. Hemoglobina e lactato aumentaram apenas no grupo de competição. A concentração de glicose reduziu em todos os grupos experimentais quando comparada ao grupo em repouso. A frequência cardíaca, a creatinina, número de eritrócitos, hematócrito e FA apresentaram aumento progressivo conforme a intensidade de exercício. Não houve alterações nos valores de AST, ureia e sódio. Conclui-se que os diferentes protocolos de exercício em equinos de salto promoveram diferentes respostas nos parâmetros hematobioquímicos.

Seventeen Brazilian Jumping horses (Brasileiro de Hipismo breed) from 5 to 12 years old were used. All animals were submitted to the following exercise protocols: rest (control group), ergometric treadmill (40 minutes at a speed of 5 m/s), mount training (40 minutes consisting of 10 minutes walking, 20 minutes trotting and 10 minutes running on field conditions) and jumping competition (speed of 350 m/min, height of obstacles 1.20 m and 430 m length). Venous blood samples were drawn from the jugular vein and heart rate were verified at rest (control) and immediately after the exercise. The erythrocyte and leucocytes count, packed cell volume, hemoglobin concentration, creatine kinase (CK), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), sodium, potassium, bicarbonate, total plasma protein (TPP), urea, creatinine were determined. The treadmill group showed higher values of PCV, heart rate and creatin...

The horse abdominal pathologies often needs surgical techniques to your complete resolution. This kind of procedure, usually a big trauma plus the anesthetic stress very important in horses, bring important systemic changes. At this work were evaluated the changes in blood constituents (cells and other components) generated by standing laparotomies followed by small colon enterotomies. The approach was made in left flank after sedation of horses with romifidine clorhidrate (80 mg.kg-1 , intravenously). The incision line in abdominal wall was infiltrated with 2% lidocaine in two different deep layers. The lateral thoracic nerve was blockade with 2% lidocaine too. The enteromies were made in ant mesenteric band of small colon. After exposition of intestinal loop, enterotomy and suture, the viscera was replaced to abdominal cavity, following the wall suture. The venous blood samples were obtained immediately before the surgical intervention and each subsequent 24 hours, for 3 days. The cell count used erythrocytes, leucocytes, basto neutrophyls and packed cell volume. The plasmatic concentration of protein, fibrinogen and hemoglobin were measured too. Variations in erythrocytes and hemoglobin results in an arise with statistic significance. The values of protein and fibrinogen as well leucocytes and bastoned neutrophils showed statistic differences. It was concluded that the cells and other values changed in a way to demonstrate an acute inflammatory pathology, compatible with an infectious syndrome, however without match with clinical status of healthy showed by horses.
