Correlations among Vetom 21.77 doses, mass and some   hematological parameters of broilers

Abstract

The research aims at revealing possible correlations among the dose of microbiological specimen vetom 21.77, body weight and concentration of erythrocytes and hematoglobulin in the poultry blood which received the specimen. The researchers arranged 5 groups: the control group and 4 experimental ones. Each group contained 20 broilers. The researchers used 5 chickens additionally in order to define critical hematological parameters before applying the specimens in the experimental groups. The specimen was applied when feeding the poultry from 1-4 experimental groups orally once a day dosed 2, 5, 50 and 300 μl / kg of weight, respectively, with food and water for 7 days. The chickens from the control group didn’t get the specimen. When analyzing the results obtained, the digital data was visualized using the swing diagrams and correlation diagrams in order to detail the observed tendencies. At the final stage of the experiment, the average absolute weight of broilers which received vetom 21..77 in the investigated doses was on 0.2-1.4% higher in comparison with the same parameter in the control group. Median parameters of the absolute poultry weight which received the specimen dosed 50 and 300 μl / kg of body weight, were on 1.4 and 1.9% higher in the control group. The number of erythrocytes in the poultry blood which received vetom 21.77 at a dose of 300 μl / kg of mass was higher at the end of the experiment than in the control group on 6.3% (P <0.05). The median of the sample exceeded the median of the control group on 8.9%. The average parameters of hematoglobulin concentration in the blood of chickens which received the specimen at doses of 50 and 300 μl / kg of mass were on 3.4 (P <0.01) and 3.8% (P <0.01) higher. Medians of these groups were higher than those in the control group on 5%. The article highlights the correlations between the dose of the specimen and live body weight (P <0.001), and between the concentration of erythrocytes (P 0.001) and hematoglobulin (P 0.001) in the blood of experimental poultry.
