Haematological parameters in Alpine goats during pregnancy

The aim of this paper was to determine the movement of haematological parameters in the blood of goats during pregnancy. The research included 24 French Alpine goats during winter feeding season. Goats were divided in the groups of 8 animals according to stage of pregnancy (up to 3 months, from 3 to 4 months, and more than 4 months). Feeding of goats was based on mixture of grains and meadow hay. In the blood of goats were determined concentrations of the haematological parameters (white blood cell count–WBC and red blood cells count–RBC as well as content of haemoglobin, haematocrit, mean corpuscular volume–MCV, mean corpuscular haemoglobin–MCH and mean corpuscular haemoglobin concentration–MCHC) and relative ratio of the individual cells of leukocytes (lymphocytes, neutrophils seg., eosinophils, monocytes and basophils). A significant decrease (P<0.05) in the content of RBC (from 15.16 to 13.11 x 1012/L) and haemoglobin (from 114.43 to 98.17 g/L) in the blood of goats during pregnancy were determined. Analysing the distribution of leukocytes is evident decline in the number of lymphocytes (from 60.86 to 57.00%) and eosinophils (from 3.14 to 1.83%) as well as increase segmented neutrophils (from 34.57 to 38.17%) and basophils (from 0.29 to 1.00%) in the blood of goats during pregnancy, but the differences were not significant (P>0.05). Comparing determined haematological parameters with reference values in the blood of goats during various stages of pregnancy, significant differences were not evident. Determined significant high positive correlations of RBC:HGB, RBC:HCT and HGB:HCT in blood of Alpine goats during different stage of pregnancy were expected. More significant high correlations was determined in Alpine goats during higher pregnancy (>4 month) which can be associated with an increased load of animals because of intensive development of the fetus. Mentioned above indicates that in determination of haematological parameters in the research model the stage of pregnancy and goat breeds should included.
