RESEARCH ON SPECIES COMPOSITION OF MICROFLORA IN POULTRY FARMS OF DIFFERENT TYPE

Introduction. For the successful development of poultry farming, control of the epizootic situation, study of the species composition of the microflora in poultry farms of different types and technological directions is important. In farms, there is a high concentration of poultry in a limited area, which creates susceptible conditions for the spread of infection. In order to prevent the development of infectious diseases in poultry farming, disinfection takes the first place in the chain of antiepizootic measures. Opportunistic microflora during multiple passages may cause the emergence and spread of poultry diseases.

The goal of the work. To study species and percentage composition of the opportunistic microflora from different types of poultry farms.

Materials and methods. A retrospective analysis of the isolated opportunistic microorganisms was carried out in Ukraine during 2017-2018. The samples were placed on a slide glass, Gram stained, and then evaluated under the immersion microscope. Bacteriological studies and identification were carried out in accordance with the Bergy Handbook.

Results of research and discussion. In the incubators, coccal microflora were more often isolated (44.3%); in the breeding farms – Escherichia coli (51.1%); in broiler farms – Streptococcus spp. and Staphylococcus spp. (38.3%); in the farms producing eggs – Escherichia coli (57.3%); in the turkey farms, the first position was on Escherichia coli (36.4%) as well as in duck (54.1%) and geese (51.3%) farms.

Conclusions and prospects for further research: 1. Analysis of opportunistic microflora, sampled from different farms, differed, which depended on the technological direction of farms. 2. On average, poultry farms in Ukraine showed E. coli isolation rates of 56.1%, Streptococcus spp. and Staphylococcus spp. confirmed in 28.2% of cases; P. aerogenosae, Proteus spp., Klebsiella spp., Citrobacter spp., Enterobacter spp., Yersinia spp., Campilobacter spp., Clostridium spp. isolated as well, in total 15.6%. In the future, we plan to conduct research devoted to the development of effective and environmentally friendly methods of disinfection of poultry.

Keywords: microflora, poultry farms, chickens, broilers, ducks, geese, turkeys.
