Abstract

SLAVOV, T., D. PANAYOTOV, I. NEDEVA, V. RADEV and I. VARLYAKOV, 2018. Haematological parameters in Lacaune ewes associated to the parity. Bulg. J. Agric. Sci., 24 (Suppl. 1): 82–87

The aim of the present study was to evaluate the changes in blood haematological parameters in Lacaune ewes at the time of the first and second lactation. To achieve the aim 26 ewes divided in two groups (first and second lactation) were investigated. Higher white blood cell counts (p<0.001), platelets and plateletcrit (р<0.05 – р<0.01) were established in the ewes in second lactation. It was also demonstrated that haemoglobin and haematocrit were similarly elevated in the second-lactation ewes (р<0.05 – р<0.01). Blood total protein, albumin and globulins in Lacaune ewes varied within the normal physiological range during the first and second lactation.
