Resumo

The objective of this research was to evaluate the influence of cells from colostrum on the health of neonate calves. Animals were distributed in 2 groups: COL+ (n = 9) which received fresh colostrum from their own damns; and COL (n = 10) which received frozen colostrums from donors. Heifers were assessed before colostrum intake - D0; D2; D7; D14; D21 and D28. Heifers were monitored by clinical examination, hematological profile and serum iron. COL - had a higher diarrhea intensity score (typically 3) on D7. Moreover, a single case each of bronchopneumonia and navel inflammation were observed in COL - calves. COL - had fewer red blood cells (RBC) (6.5 +/- 0.8 x 10(6)/mu L) and less hemoglobin (Hgb) (8.3 +/- 1.4 g/dL) than COL+ (RBC = 72 +/- 0.8 x 10(6)/mu l; Hgb = 9.6 +/- 1.3 g/dL) at D14 (P <= 0.05). COL - had more anemia on D21 (P = 0.03) and on D28 (P = 0.02). Iron was lower in COL - (5.6 +/- 2.7 mu M/L) than COL + (10.7 +/- 62 mu M/L) (P = 0.03) on D7. Lymphocytes was lower in COL - than COL + on D7 (3.8 +/- 1.0 x 10(3)/mu l COL+ and 5.4 +/- 22 x 10(3)/mu L COL -, P = 0.02). COL - calves had more anemia and lower serum iron concomitant with diarrhea on D7. The number of leukocytes was relatively consistent in the COL+ calves, while COL - calves showed an increasing number of of lymphocytes starting on D7. (C) 2017 Elsevier Ltd. All rights reserved.
