Aspectos hematológicos de caprinos (Capra hircus) da raça Canindé criados no Rio Grande do Norte Hematological aspects of Canindé goats (Capra hircus) raised in Rio Grande do Norte
Abstract
Objetivou-se com este trabalho estudar o perfil hematológico de caprinos (Capra hircus) da raça Canindé, criados no Estado do Rio Grande do Norte, como também a busca de valores de referência que se adequem à nossa região. Foram coletadas amostras sanguíneas de 58 animais clinicamente sadios, distribuídos em 4 grupos (machos acima de 5 meses, fêmeas gestantes, fêmeas não gestantes e filhotes até 4 meses de idade). A partir de única amostra de sangue de cada animal foram realizados o eritrograma (contagem de hemácias, hematócrito, hemoglobina, volume corpuscular médio e concentração de hemoglobina corpuscular média) e o leucograma (contagem total e diferencial de leucócitos). Os dados obtidos foram avaliados por meio do teste de Tukey para variáveis paramétricas e Kruskal-Wallis seguido pelo teste de Dunn para não paramétricos em nível de significância de (pThe objective of this paper was to study the hematological profile of Canindé breed goats (Capra hircus) raised in the state of Rio Grande do Norte, as well as the acquirement of reference values appropriate to our region. Blood samples were collected from 58 clinically healthy animals, distributed in 4 groups (males, over 5-month-old, pregnant and not pregnant females and young goats, up to 4 months of age). From a single blood sample from each animal, it was possible to perform the red blood cell (RBC) count, packed cell volume (PCV), hemoglobin, mean cell volume (MCV), mean corpuscular hemoglobin concentration (MCHC) and the white blood cell (WBC) count and differential). The obtained data was statically evaluated by the Tukey test for parametric variables and Kruskal-Wallis test followed by Dunn's test for nonparametric-level significance (p<0.05). The results of this study can be used as a reference for this breed of goats, making future interpretations possible from the evaluated parameters, and can support further studies in healthy or diseased animals. It shows the need for further research that demonstrates the semiarid conditions of handling and feeding, as well as assessment of variation factors on the constituents of blood taking into account sex, age and the physiological state of animals.
