Abstract. In this article, poultry enterprises in wastewater Azolla (Azolla
carolinianaWILL) the results of scientific and practical research carried out
for the purpose of plant propagation and water purification, as well as the
use of the resulting azolla biomass as additional feed for feeding broilers,
are described. During the research poultry farm enterprise After planting
Azolla in wastewater, its physico-chemical composition was studied (day
8), it was found that the water temperature in the experiment increased
from 27.5 0C to 33.8 0C, the water (pH) environment changed from acidity
to alkalinity (6.8-7, 6) increased, the color changed from reddish-yellow to
transparent, the smell disappeared, the amount of suspended matter
decreased (107.5-72.5 mg/l), the amount of oxygen (1.4-12.3 mg/l l)
increased, the amount of KBS5 (123.5-28.7 mg/l) decreased, the amount of
O2 in the oxidation process increased from 118.4 mg/l to 28.9 mg/l, and
the amount of ammonia decreased from 9.0-1.8 mg/l l, as well as the loss
of nitrites, nitrates, sulfates by 121.0-67.0 mg/l, chlorides by 113.0-54.8
mg/l, phosphates by 8.3-1.4 mg/l it was noted that it decreased to. At the
same time, the biomass of Azolla in 8 days when Azolla is planted in
poultry waste water is 100 g/m2from 750g/m2has been found to have
increased to Broiler by giving 10-25-30% additional feed from Azolla
biomass to the main feedohall are fed. Broiler johThe animals were fed for
35 days, with 30% azolla biomass as the main feedohOut of the total 340
kg of feed used during feeding, the main feed was 238 and the additional
feed was 102 kg. In this case, broiler j compared to the controlohIt is
scientifically proven that the weight of the cattle increased by 0.2 kg and
102 kg of basic feed was saved.
