Study of table erythrocyte and Haden Index for evaluation of anemia in lactating cows of Imperatriz – Maranhão region

Abstract

The Imperatriz city has great importance in the dairy region of Maranhão, which is responsible for half of the production throughout the state. Therefore, we sought the improvement of the livestock’s health in order to increase production and enhance the quality of the product produced by searching in this work the erythrocyte framework and values of Haden index for evaluation of the anemic framework of the dairy cows in the region. It was used 145 dairy cattle animals previously registered which were weekly bled in the jugular vein or Coccidial, previously disinfected with iodine 10% by 40X12 hypodermic needles, it were taken samples of 5ml of blood in disposables syringes and conditioned in flasks containing EDTA, and the samples conducted in thermal box to the Animal Biology Laboratory at the State University of Maranhão. Analyses were processed by means of conventional clinical hematology, determining the total count of red blood cells (106), the dosage of hemoglobin (g / dl) the packed cell volume (%) and the absolute hematimetric serial, MCV (mean corpuscular volume), MCH (Mean Corpuscular Hemoglobin) and the CHGM (Concentration Mean Corpuscular Hemoglobin) of each red blood cell in order to classification the absolute hematimetric series, as well as evaluation of Haden index. From the results obtained values were observed for red blood cell F = 220.1971 ** and hematocrit F = 1032.3724 ** even though it is below of the physiological average for the species, it is recorded organic conditioning to offset existing deficits with hemoglobin that is noticed below of the normal levels , taking an increase in mean corpuscular hemoglobin concentration, and F = 7.9386 ** as physiological response to a better O2 transport as ways of the animal organism compensation due to the low count of the number of circulating red cells and production of milk recorded. The Haden índex examination was found out an anemic frame – microcitichypochromic anemia, confirming the erythrogram results.
