| This study was realized to evaluate the effect of concentrate supplementation and time scales of evaluation on behavioral and physiological responses of pregnant ewes on grazing system. The experimental design was a randomized 2 x 2 x 3 factorial arrangement (two breeds: Morada and Santa Inês; two concentrate supplementation levels: 0.5 and 1.5% of body weight; and three time scales of evaluation: 10, 20 and 30 minutes) with six replicates per treatment. The physiological parameters were influenced by period of the day and breeds, with higher values in the afternoon to Santa Inês ewes. Also, influence of concentrate supplementation was found between the breeds with greater values in Santa Inês ewes. But, it did not alter the physiological parameters among... |

| This study was conducted to evaluate changes in hematological biomarkers of Nellore cows at different reproductive stages. Fifteen multiparous cows with 4 ± 1 years of age and live weight of 400 ± 50 kg were used at different stages (non-pregnant, in the initial, middle and late pregnancy, at birth, one day postpartum, 30 and 60 days postpartum). Blood collections were performed every 30 days and assayed for the following hematological biomarkers: hemogram (red blood cells, globular volume, hemoglobin, mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC)) and leukogram (total and differential counts). The erythrogram was influenced (p < 0.001) by the reproductive stages, with variation in the results obtained for the total... |
