Resumo

Este estudo visa contribuir para o avanço do conhecimento sobre os aspectos reprodutivos das cutias (Dasyprocta leporina). O objetivo foi descrever os constituintes orgânicos e inorgânicos presentes no plasma seminal de cutias analisados sob diferentes condições ambientais em uma região semiárida. O plasma seminal foi coletado de seis machos adultos por meio de eletroejaculação durante os períodos seco e chuvoso. Foram analisados componentes orgânicos (proteínas totais, albumina, colesterol, triglicerídeos, frutose e glicose) e inorgânicos (fósforo, magnésio, cálcio, ferro, cloretos, sódio e potássio). Detectaram-se maiores concentrações de glicose (88,24 e 26,27 mg/dL), fósforo (66,40 e 3,67 mg/dL) e potássio (92,67 e 19,68 mmol/L) na estação seca em comparação à estação chuvosa. As concentrações de cloreto (43,04 e 201,40 mEq/L) foram maiores na estação chuvosa. Este é o primeiro estudo a descrever a composição bioquímica do plasma seminal nesta espécie, revelando importantes correlações entre esses constituintes e os períodos seco e chuvoso no bioma Caatinga.
