The article considers the assessment of the impact of ultrasonic treatment under the influence of such parameters as pH of the environment, temperature, time and power on the chemical composition of sunflower husks as well as for waste disposal in oil extraction production with subsequent use in animal feeding in order to achieve a closed-loop economy model. Ultrasonic treatment with water at 20 °C, 15 minutes, 27 kHz increases the mass fraction of fat from 1.43% to 2.63% relative to other samples, with an increase in temperature to 70 °C, the mass fraction of crude protein increases by 5.31% and the mass fraction decreases crude fiber by 5.8% relative to control. The elemental profile of crushed sunflower husks changed with different models of ultrasonic treatment, in all samples there was an increase in the content of the mass fraction of calcium, the greatest difference was achieved in sample No. 2 times higher than control. The mass fraction of iron in almost all samples increased, the maximum value was in sample No. 5 (ultrasound treatment at 20 °C, 15 minutes, 27 kHz + lactic acid to pH – 4) by 24.9 mg/kg higher relative to the control. The impact of ultrasound on the samples, gives a decrease in the content of palmitoleic acid to 0.3% and an increase in stearic acid by 0.8% relative to the sample not subjected to ultrasonic treatment.

Relevance. Today, a significant place in the feeding of farm animals is given to such inexpensive waste from the oil extraction industry as sunflower husk. In this regard, one of the promising and modern methods for optimizing feed production can be the use of liquid media activated in various ways, in combination with ultrasonic treatment. Materials and methods. The object of research was crushed sunflower husk (1.0 mm) (sample 1), as well as husk sonicated (cavitated) in hydromodules with water (in the ratio “husk: water” 1 : 3 (sample 2)), and with lactic acid (“husk: lactic acid” 1 : 3 (sample 3)). The obtained samples were used in in vitro studies with rumen fluid in the “Daisy D200I” incubator (“Ankom Technology”, USA). The following indicators of the exchange of nitrogenous metabolites in the cicatricial contents were determined – residual and total nitrogen by the Kjeldahl method according to the method of K. K. Akhazhanova (2016); ammonia nitrogen – by microdiffusion method according to Conway. The taxonomic composition of the scar fluid was determined by NGS-sequencing using the “MiSeq device” (“Illumina”, USA). Research results. Data analysis showed that the use of cavitated sunflower husk increases the digestibility of dry matter by 19.0 % (Р ≤ 0.01), and cavitated together with lactic acid husk – by 20.7 % (Р ≤ 0.01) in comparison with crushed husk. When incubating cavitated sunflower husk and cavitated together with lactic acid sunflower husk, there were a decrease in the number of archaea, in particular the class Methanobacteria, by 23.73 % and 20.36 % (Р ≤ 0.05) and an increase in the number of bacteria of the phyla Bacteroidetes by 10.2 % and 11.27 %, Firmicutes – by 4.66 % and 6.86 % relative to the use of crushed husk.
