Haematological parameters and acid-base balance of goat kids in organic breeding

The aim of the study was to determine haematological parameters and acid-base balance of the goat kids´ blood from organic breeding. Goat kids were 45 days old and in the suckling period. Along with suckling, goat kids were fed with mixture of cereals and meadow hay. Blood was sampled in the morning, after suckling, from the jugular vein and was immediately transported to the laboratory. Determining of haematological parameters (number of leukocytes and erythrocytes, hemoglobin, hematocrit, mean corpuscular volume - MCV, mean hemoglobin content in erythrocytes - MCH and mean hemoglobin concentration in erythrocytes – MCHC) was conducted on automated hematology analyzer Sysmex pocH-100iV, while acid-base balance parameters of goat kids´ blood (pH of blood, BE of blood, gases in the blood: pCO2, pO2 and tCO2 and electrolytes: Na, K, Cl and bicarbonate) were conducted on acid-base analyzer Rapid Lab 348. Then, the anion gap, strong ion difference and z value from the blood of goats were measured. Results of the research were analyzed by descriptive statistics and compared with current reference values for goats. With analysis of haematological and blood acid-base balance parameters in the organic breeding, small changes of analyzed parameters (except pH value and electrolytes) were observed when compared with reference values for goats. Mentioned changes can be attributed to age due to the pronounced growth and maturation of most organs in suckling goat kids. Therefore, it is very important when choosing animals from the herd for the production of haematological parameters and determination of blood acid-base balance, to take age of animals as an important factor in order to obtain better results.
