Resumo: Well adapted animals are characterized by maintain homeostasis under natural conditions. The present study aimed to evaluate physiological and morphological responses, as well as identify the relationship between these parameters in order to maintain homoeothermic status, in the dry and rainy season. Measurements were taken from 383 Morada Nova hair ewes, under dry and rainy season. The studied variables included rectal temperature (RT), respiratory rate (RR), coat thickness (CT), hair length (HL), hair diameter (HD) and hair density (D). Blood samples were collected for determining biochemical, erythrogam and hormone concentration. The evaluated blood parameters from the Morada Nova breed did not demonstrate any variation from the reference interval established for sheep, confirming its adaptability profile even under high radiation and air temperatures. Multivariate analyses were performed in order to determine relationship between morphological, biochemical, erythrocyte and hormonal traits in each season. Differences correlations were observed according to season of the year. In the dry season, the correlations were significant among RT, RR, Packed cell volume (PCV), thyroxine (T4), Glucose (GLU), CT, HL, Globulin (GLO) and Total Protein (TP), whereas in dry season the characteristics that showed greater correlation were Mean corpuscular volume (MCV), thyroid hormones, Creatinine, GLO, TP, PCV and GLU. In conclusion, Morada Nova ewes was able to maintain homeothermy, even in the most stressful environmental conditions. Their hematological, biochemical and hormonal profile were within the normal range for sheep, confirming the adaptability of this local breed to the Brazilian semiarid environment.

O presente estudo teve como objetivo avaliar as respostas fisiológicas e morfológicas, bem como identificar a relação entre esses parâmetros a fim de, manter o estado homeotérmico, na estação seca e chuvosa. As medições foram tomadas em 383 ovelhas da raça Morada Nova, na época seca e chuvosa. As variáveis estudadas incluíram temperatura retal (TR), frequência respiratória (FR), espessura do pelame (EP), comprimento do pelo (CP), diâmetro do pelo (D) e densidade numérica (DN). Foram coletadas amostras de sangue para determinar a concentração bioquímica, eritrogama e hormonal. Os parâmetros de sangue avaliados da raça Morada Nova não demonstraram variação do intervalo de referência estabelecido para ovinos, confirmando que seu perfil de adaptabilidade, mesmo sob alta radiação e temperaturas do ar. Foram realizadas análises multivariadas para determinar a relação entre características morfológicas, bioquímicas, eritrocitárias e hormonais em cada estação. As correlações de diferenças foram observadas de acordo com a estação do ano. Na estação seca, as correlações foram significativas entre TR, FR, PCV, T4, GLU, CT, HL, GLO e TP, enquanto que na estação seca as características que apresentaram maior correlação foram MCV, T4, T3, CRE, GLO, TP PCV e GLU. Em conclusão, as ovelhas Morada Nova conseguem manter a homeotermia, mesmo nas condições ambientais mais estressantes. Seu perfil hematológico, bioquímico e hormonal permanecem dentro da faixa de normalidade para ovinos, confirmando a adaptabilidade dessa raça local ao ambiente semiárido brasileiro.UEL2018-08-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3277410.5433/1679-0359.2018v39n5p2261Semina: Ciências Agrárias; Vol. 39 No. 5 (2018); 2261-2272Semina: Ciências Agrárias; v. 39 n. 5 (2018); 2261-22721679-03591676-546Xreponame:Semina.
