Selected Blood Biochemical and Haematological Parameters in Turkeys after an Experimental Probiotic Enterococcus faecium M-74 Strain Administration

Abstract

In this study selected biochemical (cholesterol, total lipids, triglycerides, calcium, inorganic phosphorus) and haematological parameters (erythrocytes and leucocytes count, heamatocrit) in blood of turkeys, BIG 6 breed, after probiotic strain Enterococcus faecium M-74 administration added to the feed mixture and drinking water during 12 weeks of feeding were analyzed. Animals were divided into three groups: control and two experimental groups P1 and P2. Preparation with Enterococcus faecium M-74 5.10⁹ CFU (colonies forming units) in amount of 300g/1000kg (0.03%) to the feed mixture of P1 group was supplemented. Animals in group P2 received probiotic preparation from the drinking water (structured doses from 2.10₈ to 30.10₈ daily for animal according to age and live weight).The lowest concentration of total lipids in control group 4.79 ± 0.30mmol/L was found as compared with values 4.91 ± 0.34mmol/L in P1 group and 5.34 ± 0.48mmol/L in the P2 group. The highest average concentration of triglycerides in the control group 3.38 ± 0.09mmol/L was observed. In the experimental groups the concentration of this parameter was significantly lower (2.74 ± 0.10mmol/L in P1 group and 2.75 ± 0.21mmol/L in P2 group). The lowest average concentration of cholesterol 3.73 ± 0.11mmol/L was detected in control group, followed by 3.77 ± 0.19mmol/L in P1 and 3.78 ± 0.29mmol/L in P2 group. The highest values of calcium and inorganic phosphorus were found in control group (2.44 ± 0.03mmol/L and 1.81 ± 0.09mmol/L). Slightly higher values without significant differences in both experimental groups were found. In the case of haematological parameters any significant differences were found in erythrocytes and leucocytes count and haematocrit.
