Kasianenko S. The development of alternative methods of ducks bacteriosis prevention

In the dissertation work the results of the experimental research as for the methods of ducks bacteriosis prevention on the basis of increasing data of natural resistance of an organism of a bird introduction to the ration of prebiotic fraction of mannan oligosaccaharides (“Actigen”, Alltech inc.) and development of effective and ecologically safety mean of disinfection of duck houses by alkaline detergent-disinfectant “Sandez” are given. Isolates of E. coli, S. Typhimurium, P. aeruginosa, S. saprophyticus were found to be sensitive to antibacterial drugs of the aminoglycoside group (≥ 90%) and fluoroquinolones (≥ 80%). E. coli isolates are resistant to cephalosporins (β-lactams) of the II and IV generation and carbapenes - 88.2%, 94.1% and 94.1%, respectively; salmonella isolates - to cephalosporins (β-lactams) III and carbapenes - 69.2–76.9%; P.aeruginosa is resistant to generation IV cephalosporins in 88.8%. The proposed methods of prevention of bacteriosis of ducks are effective and provide an increase in live weight of ducks at 49 days of age by 4.1 (p≤0.05), the average daily germination - by 1.5 (p≤0.05)% and the safety of livestock poultry - by 0.9% (p≤0.05) compared to control, and the economic effect of 1 UAH. costs is 4.3 UAH.
