The lambs were weaned with 60 days of age and fed during the day, with water and mineral salt ad libitum, in enclosures of 0,8ha, with red clover manured pasture (Trifolium pratense L.) and white clover (Trifolium repens L.) and at night they were sheltered in collective stalls and supplemented with alfalfa hay (Medicago sativa L.). The animals were wormed and vaccinated against enteroxotemy. Samples of veiny blood of 10mL were collected from the jugular vein, and in 3mL anti-coagulant Ethylenediaminotetraceticodissodic was added, in 10% concentration, by means of 0,1mL in each 5mL blood for the hematologic survey, while the remaining 7mL were coagulated, and its serum was used for the biochemical dosing. From the ear 1mL of artery blood was collected in order to establish the hemogasometric values. The average hematologic values which were gotten for the studied ages were, respectively, hematocrit or globular volume (VG) 32,50; 33,06 and 35,80%; the average corpuscular hemoglobinic concentration (CHCM) was 36,73; 37,02 and 38,09g/dL; erythrocyte 9,86x106; 10,69 x106 and 9,04 x106 per &#956;L; hemoglobin (Hb.) 11,92; 12,60 and 12,97 g/dL; average corpuscular hemoglobin (HCM) 12,12; 12,16 and 14,1 pg. The plasmatic biochemical values referring to the researched ages were, respectively, glucose 79,09; 81,57 and 82,96 mg/dL; cholesterol of 42,37; 45,94 and 47,51 mg/dL; magnesium pf 1,90; 1,81 and 1,87 mg/dL; phosphorus of 7,47; 7,34 and 7,19 mg/dL; total calcium 11,37; 11,18 and 11,15 mg/dL; sodium of 155,11; 150,73 and 154,18 mEq/L; potassium of 4,86; 4,76 and 4,91 mEq/L. The hematologic values, according to sex, were respectively, hematocrit or globular volume (VG) 30,35 and 30,03%; average cospuscular hemoglobinic concentration (CHCM) 37,69 and 36,95 g/dL; erythrocytes of 9,03x106 and 10,25x106 per &#956;L; hemoglobin (Hb) 11,42 and 12,96 g/dL; average corpuscular volume (VCM) of 34,29 and 34,28 fL; leucocytes of 10,45 and 13,03 cel./ &#956;L; average cospuscular hemoglobin (HCM) 12,91 and 12,67 pg. The plasmatic biochemical values according to sex, were respectively, glucose of 82,37 snf 81,48 mf/dL; cholesterol of 44,03 and 46,44 mg/dL; magnesium of 1,87 and 1,85 mg/dL; phosphorus of 6,72 and 7,95 mg/dL; total calcium 11,13 and 11,31 mg/dL; sodium of 153,31 and 153,37 mEq/L; potassium of 4,74 and 4,94 mEq/L. The average hemogasometric values, corrected for he corporal temperature of 38ºC, according to the ages of 120, 180 and 240 days were, respectively, pH 7,45; 7,44 and 7,44; PaCO2 of 34,88, 34,65; 31,94 mmHg; PaO2 81,86; 77,68; 78,52 mmHg and BE 1,08 -1,78 and 0,13mEq/L. For the sex variable it was registered, respectively as pH of 7,45 and 7,38; PaCO2 pf 37,71 and 31,00 mmHg and PaO2 of 75,29 and 83,42 mmHg and BE 1,08 and 1,04 mEq/L. There was no meaningful difference (P<0,05) for the researched variables. The behaviorial data were obtained through visual observation, on the field, with interval of 5 minutes, during consecutive daily periods of 10 hours, in the experimental age bands, corresponding to the months from December 2003 to February and april 2004. Weighing was held at each 14 days, in a total of 15 trials. The scores of time spent in pasturing in the sun presented average values of 5,58; 5,00 and 1,70 h/day; the pasturing in the shadow consisted of average times of 1,70; 2,37 and 5,28 h/day xiii 14 and the rumination time in the shadow corresponded to 1,23; 1,88 and 1,77 h/day. The average values of daily weight gain, from birth to weaning and from weaning to the 240 days were, respectively, of 25,67 and 229,74 g/d. The data were analysed and delineation was entirely determined in factorial structure for sex and age. There was no effect (P<0,05) of interaction between age and sex, and from the sex factor to the analysed variables / Foram estudados os efeitos de idades aos 120, 180 e 240 dias, sobre o comportamento alimentar e o desempenho ponderal de treze cordeiros da raça Texel.

Não houve diferença significativa (P<0,05) para as variáveis estudadas. Os dados comportamentais foram obtidos por observação visual, a campo, a cada cinco minutos, por três períodos diários consecutivos de dez horas, nas faixas etárias experimentais, correspondendo aos meses de dezembro de 2003, fevereiro e abril de 2004. Efetuaram-se pesagens a cada quatorze dias, totalizando quinze pesagens. Os tempos despendidos em pastejo ao sol, apresentaram valores xi 12 médios de 5,58; 5,00 e 1,70 h/dia; em pastejo à sombra, tempos médios de 1,70; 2,37 e 5,28 h/dia e tempo de ruminação à sombra de 1,23; 1,88 e 1,77 h/dia.
