observed by the formation of IAs of dyes with heteropoly anions, iodide or rhodanide
metal complexes and polyelectrolytes. Most of the found phenomenons are
satisfactorily explained in the frame of exciton theory. Approaching of the dye ions can
occur due to the formation of precipitate of IA between cationic dyes and heteropoly
anions or anionic metal complexes or formation of ion-association bond between
anionic dyes and closely placed positively charged groups of cationic polyelectrolytes.
Changes in the absorption spectrum are caused then by π-π interaction of aromatic
systems of dyes and the formation of J- or H-aggregates.
The fourteenth section “BY-PRODUCTS OF APRICOT PROCESSING AS A
SOURCE OF FUNCTIONAL COMPOUNDS: ANTIOXIDANTS AND INHIBITOR
OF CORROSION”. Environmentally-friendly tactics become one of the key standard
of modern industry. One of them is the practice of employing waste of plants that is
present in huge amounts for further industrial applications. Its utilization as promising
alternative to environmentally-toxic traditional chemical inorganic corrosion inhibitors
(synthetic) received a special attention. Here the protection performance of self-
assembled monolayers (SAMs) formed by apricot pomace extract (APE) on the surface
of steel has been studied. Characterization of the apricot pomace extract was carried
out using Fourier transform infrared spectroscopy (FTIR) and gas chromatography-
mass spectrometry (GC-MS) analysis. The antioxidant properties of APEwere
studiedby using a series of methods (total antioxidant activity, reducing power). The
anti-corrosion effect of the SAMswas determined by weight loss experiments, scanning
electron microscopy, FT-IR and electrochemical methods.

“INFLUENCE
OF
PHARMAZIN
AND
TILOTSIKLINVET ON THE BROILER CHICKENS’ PRODUCTIVITY”.
Chemicals of the macrolide group – pharmazin and tilotsiklinvet – are widely used in
veterinary practice in poultry farming for a treatment or a prevention, in particular in
Ukraine. Four groups of broiler chickens of the Cobb 500 day-old cross-breed were
formed: two control and two experimental (12 broiler chickens each). Chickens of the
first experimental group were fed with pharmazin containing the active substance (AS)
tylozine tartrate 500 mg per 1 g, and the second – with a tilotsiklinvet containing the
(AS) tylozine tartrate and doxycycline glycate of 100 mg per 1 g of powder. These
antibiotics were fed to broiler chickens with preventive purpose for the first 3 days of
life, 28−29 and 38−42 days of the experiment. It has been established that the use of
pharmazin and tilitsiklinvet positively affects the productivity of chicken broilers. As
a result, one can observe a significant increase in weight of broiler chickens before a
slaughter (р≤0.001, р≤0.01). Slaughter yield increased by 8,2% when feeding
pharmazin, and tilotsiklinvet – by 4.3 %. Also, the weight of all the edible internal
organs increased when using pharmazin and tilotsiklinvet (p≤0.05) and the weight of
the liver and muscular part of the stomach when using tilotsiklinvet (p≤0.05).
