Impact of various reagents during blood collection from poultry to analyze morpho-biochemical indicators
Abstract
The work provides experimental data on the impact of anticoagulants (K3 - EDTA, 3.8% sodium citrate and lithium heparin) and coagulation activator on morpho-biochemical indicators in the blood samples of broiler chickens of cross-selection of Agricultural Center “Smena” at the age of 35 days. The studies were carried out with the use of semi-automatic flow analyzer Sinnowa BS-3000P (SINNOWA Medical Science & Technology Co., Ltd, China) and veterinary automatic blood analyzer DF-50 by Dymind Biotech (PRC) with the use of original reagents. The results showed that the most optimal reagent for determination of morphological indicators of the poultry blood was EDTA. The average white blood count (WBC) is lower in blood samples with citrate and heparin in contrast to EDTA by 30.5% and 24.1%, respectively. The average red blood count (RBC) is lower in tubes with sodium citrate (by 37.9 %) and lithium heparin (by 13.8 %) in contrast to K3-EDTA. When the sodium citrate anticoagulant is used, the blood biochemistry results for all positions of the experiment, excluding calcium, are lower than in heparin, and its closest values are lower than in coagulation activator, excluding trypsin activity. That’s why, the most optimal reagents for biochemistry, including for blood enzyme tests, should be considered the tubes with heparin or coagulation activator.
