Comparative analysis of haematological parameters of guinea fowl of different breeds and populations

Abstract

Comparative analysis of haematological parameters of some breeds and populations of Guinea fowl grown in the Russian Federation was carried out. The following breeds were studied: Volga white breed, the French breed BroilerGuineaFowl ESSOR MI. LF, the Zagorsk white-breasted breed. The following coloured populations were examined: gray-mottled, blue from the CJSC “Mariyskoye” of the Mari El Republic and gray-mottled from Sergiev Posad. Contents of haemoglobin g/l, erythrocytes 1012 l, leukocytes 109 and thrombocytes thousand/mcl, as well as the nuclear Arneth’s count (percentage ratio of different types of leukocytes) were determined in blood of Guinea fowls The pseudoeosinophil / lymphocyte ratio was calculated. Standard hematological methods were used. Statistical processing of the results was carried out with the help of a single-factor analysis of variance. It was established that the clinical picture of blood of the examined Guinea fowls is characterized by uniformity of type. An exception is toms and hens of the Essor breed that had higher and lower hemoglobin level correspondingly in relation to the same haematological parameter of other groups of the examined birds. The average values of the hemoglobin level in the studied breeds and the populations of Guinea fowl ranged from 85.0 ± 4.4 g / l to 128.0 ± 6.98 g / l. Blood of the studied groups of Guinea fowls did not differ significantly in relation to all other clinical haematological parameters. The nuclear Arneth’s count of blood of Guinea fowls of all studied groups corresponds to the normal amount of mature birds of most species. First of all, it is characterized by the lymphocytic profile. The second position in the quantitative content of cells in the nuclear Arneth’s count is taken by pseudoeosinophils. The structure of the nuclear Arneth’s count of blood depends on the breed or population. The white blood cell count of the French Guinea fowls has some peculiarities. The obtained values of the clinical haematological parameters of the examined Guinea fowls make it possible to conclude that the studied groups of birds are relatively healthy.
