AVILEZ COLON, Berta Lucía; RUGELES PINTO, Clara Cecilia; JABIB RUIZ, Leonel  and  HERRERA BENAVIDES, Yonairo Manuel. Hematological Parameters in Broilers Reared in a Closed Production Farm in the Low Tropics. Rev. Med. Vet. [online]. 2015, n.29, pp.33-39. ISSN 0122-9354.

Hematology and blood chemistry are useful tools to establish a definitive diagnosis, to guide and explore the nature of pathophysiological situations that affect birds. Several diseases of poultry can change blood parameters, which are little studied in Colombia. This study aims to determine degrees of blood hematological parameters in broilers (1-42 days old) reared under experimental conditions. Blood samples were taken during the second, fourth and sixth weeks of age. Average results were: hematocrit (PCV %): 27.53; hemoglobin (Hb g/dL): 9.20; mean corpuscular volume (MCV fl): 43.10; mean corpuscular hemoglobin concentration (MCHC g/dL): 33.17; erythrocytes (Eri 106 µl): 6.98; leukocytes (Leu 103 µL): 19.69; absolute relative values for lymphocyte (Lin %): 72.58; heterophile (Het %): 35; monocytes (Mon %): 9.8; eosinophils (Eos %): 17.8, and basophils (Bas %): 1.08. These results are within normal ranges, and present small variations attributable to environmental conditions and to those of confinement. Therefore, further studies are needed on this topic in the region.
