Resumo: To evaluate the mean plasma concentrations of total cholesterol (TC), high density lipoproteins (HDL) and cortisol, blood samples were collected of five Ideal-Polwarth rams, maintained at 22?53’S latitude, in semi-confinement, every two months throughout the year, by 24h period, with 2-hour intervals between colects. The TC, changed 40.70?1,11mg/dL (April) and 61.48?1,11mg/dL (December), between months, while HDL changed 22.16?0.23mg/dL (December) as 33.40?0.23mg/dL (February), but not make evident a circannual rhythm in this levels. The TC presented the lowest value at 16:30h (50.40?1.57mg/dL) and the highest value at 8:30h collect (54.67?1.57mg/dL); the HDL lowest level was at 10:30h (27.04?0.33mg/dL) and the highest level also at 8:30h collect (28.49?0.33mg/dL), however without permit circadian rhythm determination in your plasma concentrations. Similarly, the cortisol plasma concentrations, between collect months, presents variable, however without demonstrate circadian rhythm in this hormone secretion. In relation to different collection’s moments, throughout months, it wasn’t possible to define, by statistical analysis, a circadian rhythm of cortisol secretion. KEY WORDS: Ovine, adrenal hormone, biochemistry metabolites, circadian rhythm.

O CT oscilou entre 40,70±1,11mg/dL (abril) e 61,48±1,11mg/dL (dezembro), entre os meses, enquanto HDL variou de 22,16±0,23mg/dL (dezembro) a 33,40±0,23mg/dL (fevereiro), mas não evidenciando um ritmo circanual em seus níveis. O CT apresentou seu valor mínimo na colheita das 16h30min (50,40±1,57mg/dL) e o máximo às 8h30min (54,67±1,57mg/dL); o menor valor de HDL foi obtido às 10h30min (27,04±0,33mg/dL) e o mais alto também às 8h30min (28,49±0,33mg/dL), não permitindo a determinação de um ritmo circadiano em suas concentrações plasmáticas. De forma similar, as concentrações de cortisol plasmático, entre os meses de colheita, apresentaram-se variáveis, mas ainda sem demonstrar um ritmo circanual na secreção deste hormônio. Com relação aos diferentes momentos de colheita, ao longo das 24 horas, assim como entre os meses, não foi estatisticamente possível a definição de um ritmo circadiano de secreção de cortisol.
