Azolla of poultry farms, reproduction, production of its biomass'use as additional feed

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.
