Effect of Age on Normal Blood Count Values in Landim Cattle Raised in the Extensive System, in the Districts of Xai-Xai, Limpopo and Chongoene, Gaza Province of Mozambique

The research aimed to establish normal blood count values and evaluate influence of age in 56 Nguni cattle, raised in Mozambique. Were used blood samples to determine the blood count. Was performed Statistical analysis using the SAS package and Duncan's parametric test at 5% significance. The age influenced the blood count on in this research. The blood count values adopted outside the African continent for various breeds of cattle cannot be used to support clinical diagnosis in Mozambique. Based on the confidence interval, the following normal values can be presented for the erythrogram: red blood cells between 6.78 and 7.40 x10⁶ / µL; hemoglobin between 10.77 and 11.36 g/dL, hematocrit between 28.02 and 29.56%, MCV between 39.91 and 43.02 fL, MCH between 15.27and 16.44 pg, MCHC between 37.86 and 39.10 % and RDW between 16.98 and 19.40 %. For the leukogram, the following normal values were obtained: Total Leukocytes between 14,106 and 16,233 /µL, Basophils between 32 and 165 /µL, Eosinophils between 823 and 1262 /µL, Band Neutrophils between 25 and 87 /µL, Segmented Neutrophils between 2,510 and 3,249 /µL, Total Neutrophils between 2,565 and 3,306 /µL, Lymphocytes between 9,471 and 11,474 /µL and Monocytes between 154 and 296 /µL
