Valores Hematológicos de Referencia para el Ganado Vacuno Holstein friesian de la Campiña de Cajamarca.

RESUMEN

El presente trabajo de investigación se llevó a cabo en el Laboratorio de Fisiología Veterinaria de la Facultad de Ciencias Veterinarias de la Universidad Nacional de Cajamarca, que se encuentra ubicada a 7º10' de latitud sur y 78º38' de longitud oeste, y a 2536 m.s.n.m. durante los meses de enero a marzo de 1999.
La investigación se realizó con la finalidad de establecer valores hematológicos de referencia para el ganado vacuno Holstein friesian de la campiña de Cajamarca, mediante el método de los promedios (Promedio ± 1,96 D.E.). Se utilizaron 107 vacunos hembras de la raza Holstein friesian aparentemente sanos, de los cuales fueron tomadas las muestras de sangre con anticoagulante (EDTA), mediante veno punción coccígea utilizando el sistema de tubos al vacío. Finalizado el estudio se determinó los siguientes valores de referencia: Eritrocitos 4.2 a 8.6 x 106 /ul, Volumen Globular Aglomerado (VGA) 25.7 a 40.5 %, Hemoglobina 8.6 a 13.3 g/dl, Volumen Corpuscular Medio (VCM) 40.3 a 64.1 fl, Hemoglobina Corpuscular Media (HCM) 12.8 a 21.8 pg, Concentración de Hemoglobina Corpuscular Media (CHCM) 27.6 a 39.0 g/dl; Leucocitos 5.0 a 13.6 x 103 /ul, Neutrófilos Segmentados 11 a 43 % ó 1.0 a 3.8 x 103 /ul, Neutrófilos Baciliformes 0 a 2.9 % ó 0 a 0.3 x 103 /ul, Eosinófilos 0 a 22 % ó 0 a 2.1 x 103 /ul, Basófilos 0 a 1.9 %, ó 0 a 0.14 x 103 /ul, Linfocitos 337 a 77 % ó 1.8 a 8.8 x 103 /ul, Monocitos 0 a 11 % ó 0 a 1.1 x 103 /ul.



SUMMARY

The present research was carried out in the laboratory of Veterinary Physiology of the Veterinary Science Faculty of The National University of Cajamarca, which is located between the parallels 7º10' south latitude and 78º38' west longitude, at an altitude of 2536 meters above the sea level, during the months from January to March, 1999.
The research has been done with the purpose of establishing haematological reference values to Holstein friesian cows in the Cajamarca valley through the mean ± 1.96 standard error. One hundred and seven (107), female cows Holstein friesian, "apparently healthy", were used in the research. The blood samples were taken through the punction of the coccigea vein, into tubes containing EDTA as anticoagulant. At the end of the research the following results were found: from 4.2 to 8.6 x 106 /ul, for the Erythrocytes, from 25.7 to 40.5 % for the Packed Cell Volume (PCV), from 8.6 to 13.3 g/dl for the Haemoglobin (Hb), from 40.3 to 64.1 fl for the Mean Corpuscular Volume(MCV), from 12.8 to 21.8 pg for the Mean Corpuscular Haemoglobin (MCH), from 27.6 to 39.0 g/dl for the Mean Corpuscular Haemoglobin Concentration (MCHC); from 5.0 to 13.6 x 103 /ul for the Leucocytes, from 11 to 43 % or 1.0 to 3.8 x 103 /ul for Segmented Neutrophils, from 0 to 2.9 % or 0 to 0.3 x 103 /ul for Non-Segmented Neutrophils, from 0 to 22 % or 0 to 2.1 x 103 /ul for Eosinophils, from 0 to 1.9 % or 0 to 0.14 x 103 /ul for Basophils, from 37 to 77 % or 1.8 to 8.8 x 103 /ul for Lymphocytes, from 0 to 11 % or 0 to 1.1 x 103 /ul for Monocytes.
