Eritrograma e leucograma como ferramenta para avaliar animais de produção: influência do período gestacional e puerpério, alimentação e raça.

Abstract

The objective of this study was to evaluate the influence of gestation and puerperium, feeding and breed on the hemogram of sheep. We used 40 sheep, 20 of Santa Ines and 20 Morada Nova, distributed in a completely randomized design in a split plot arrangement in time. During the experimental period, the animals were kept in pickets of Andropogon gayanus pasture being collected in the late afternoon to be supplemented. Blood samples were taken every fourteen days, always in the morning, before the animals were released into the pasture, by jugular vein puncture for blood count. There was no influence on the level of supplementation in the erythrogram (P <0.05). In leucogram, the concentrate supply influenced only neutrophiles (P <0.05). The Morada Nova breed had higher hemoglobin and hematocrite and total leukocyte count than the Santa Ines breed. On the influence of pregnancy and puerperium in the erythrocyte, it is observed that during this period there is a reestablishment of the values of blood crasis, including total plasma proteins that increase during this period as compensation to the fetus and high nutritional requirements, remaining until the end of the puerperium when the lambs were weaned. The facts discussed above show that there was no influence of the gestation and puerperium period on the erythrogram of the animals under study, however, supplementation and breed are influential in the leukocyte status of these animals.
