The aim of this study was to investigate haematological changes in lactating goats with subclinical mastitis. Determination of mammary health status was based on CMT results, microbiological and cytological examination. Blood samples were taken from all goats included in the study by venopuncture of the jugular vein and blood was collected in vacuum blood collection tubes. The results showed that the mean ± SE in healthy animals and goats with subclinical mastitis were as follows: Red Blood Cell count (RBC) 10.43 ± 0.63×1012/L and 9.38 ± 0.42×1012/L; Haemoglobin (Hb) 85.69 ± 2.43 g/L and 77.13 ± 1.73 g/L; Hematocrit (HCT) 18.77 ± 0.87 % and 17.77 ± 0.68 %; Red Blood Cell Distribution (RDW) 21.55 ± 0.16 % and 22.21 ± 0.13 %; Mean Cell Volume (MCV) 16.96 ± 0.29 fL and 15.63 ± 0.20 fL; Mean Cell Haemoglobin (MCH) 6.18 ± 0.10 pg and 6.73 ± 0.09 pg; Mean Cell Haemoglobin Concentration (MCHC) 379.81 ± 3.72 g/L and 378 ± 3.12 g/L; White Blood Cell Count (WBC) 13.37 ± 1.60×109/L and 16.66 ± 1.23×109/L. The RBC and Hb were significantly higher (P<0.05) in normal lactating compared to goats with subclinical mastitis. RDW, MCH and WBC count was significantly lower in healthy goats.
