Dolbanosova R. Pathomorphological characteristics of pyrrolizidinoalkaloid's nephropathologies in cattle.

Relative and pathogenic microflora analyses of African ostriches breeding in different Ukrainian regions have been given in the thesis. Relative and pathogenic microflora from hatchibators, brooders and places for keeping embryos and ostriches corpses as pathogenic material has been defined. Microflora keeping aspects of places depends on technological direction and ostrich's age which have been kept in them. Pathogenic strains of organisms caused 64-100% of white mice death has been found in relative and pathogenic microflora content. Investigation of relative and pathogenic microflora sensibility to antibiotic defined their stability to ampicillin, oxacillinum, cefazolin. Kanamicini, neomicini ctreptomicini, eritromicini, polymicini have been shown. Efficiency of "Brovades plus" preparation as water disinfectant for ostriches has been proved. Stronger action of "Bio-mos" probiotic in comparison with Bioflor have been established. Feeding with "Bio-mos" probiotic and Bioflor probiotic supply the decrease of feed losses and increase of daily-weight and ostriches safety. Complex of disease prevention approaches caused pathogenic microflora increase the qualitative meat indices of ostriches.
