Resumo: | This study aimed to evaluate the effects of heat stress and characterize the coat characteristics of red and white varieties of Morada Nova sheep raised in the semiarid region of Brazil during the rainy and dry seasons. The following variables were investigated: coat thickness (CT), inclination angle of the coat (?I), hair coat density (HDE), hair length (HL) and hair diameter (HD), in conjunction with the physiological responses of rectal temperature (RT) and respiratory rate (RR). The data were tested with an analysis of variance, a Tukey test at a 5% significance level and a correlation analysis. The season of the year (dry and rainy) and the variety (red and white) were used as fixed effects in the analysis of variance. HL, HDE and HD were significantly greater in the dry season than in the rainy season (P < 0.05), but CT and ?I did not differ between seasons (P > 0.05). HL, HDE and HD were lower and ?I was greater (P < 0.05) for the red variety, but CT was statistically equal (P > 0.05) for the two varieties. It was concluded that the coat characteristics of the Morada Nova ewes favor the adaptation of the sheep to a semiarid environment, including the improved protection of the skin against ultraviolet radiation. In general, the white variety presented characteristics reflecting a higher degree of adaptation to the conditions of the Brazilian semiarid region. |

Foram avaliada espessura de pelame (CT), ângulo de inclinação do pelo (I), número de pelos (HDE), comprimento do pelo (HL) e diâmetro do pelo (HD), em conjunto com as respostas fisiológicas temperature retal (RT) e frequência respiratória (RR). Foram realizados análise de variância e teste de Tukey a 5% de probabilidade. A estação do ano (seca e chuvosa) e variedade (vermelha e branca) foram usadas como fatores fixos. HL, HDE e HD foram significativamente maiores na estação seca (P < 0,05), mas CT e ?I não diferiram. HL, HDE e HD foram menor e ?I foi maior na variedade vermelha, CT não apresentou diferença em relação a variedade. Conclui-se que as características de pelame das ovelhas Morada Nova favorecem a adaptação a ambiente semiárido, incluindo proteção da pele contra o excesso de raios ultravioleta, com a variedade branca apresentando-se mais favorável à adaptação nas condições da região semiárida brasileira.UEL2018-05-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2959510.5433/1679-0359.2018v39n3p1281Semina: Ciências Agrárias; Vol. 39 No. 3 (2018); 1281-1294Semina: Ciências Agrárias; v. 39 n. 3 (2018); 1281-12941679-03591676-546Xreponame:Semina.
