Previous issue date: 2005-08-09 / The effects of the age on the 120th, 180th and 240th days, concerning the nourishing
behavior and the ponderal performance of thirteen Texel lambs were studied.The
research was conducted in the Sector of Sheep Raising of CAV/UDESC, Lages, SC.
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 μL; 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 μL;
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./ μL; 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. O experimento foi realizado no Setor de Ovinocultura do CAV/UDESC em
Lages, SC. Os cordeiros foram desmamados aos 60 dias e alimentados durante o
dia, com água e sal mineral ad libitum, em piquete de 0,8 hectare com pastagem
cultivada de trevo vermelho (Trifolium pratense L.) e trevo branco (Trifolium repens
L.) e à noite eram estabulados em baias coletivas e suplementados com feno de
