Abstract

The development of plant-based feed additives is a relevant area of modern biotechnology aimed at improving the sustainability and efficiency of animal husbandry. Fast-growing plants with high biomass accumulation potential, such as Paulownia tomentosa, are of particular interest. Objective. The study aimed to obtain microclonal biomass of P. tomentosa under in vitro conditions and to evaluate its potential feed value based on biochemical and functional indicators. Methods. Microclonal propagation was carried out using standard protocols. The biomass was analyzed for crude protein, fiber, amino acid compo-sition, and microelement content. Antioxidant activity was determined using DPPH and ABTS assays. The potential feed value was assessed using model feed rations and calculated indicators of digestibility and me-tabolizable energy. Results. It was established that the microclonal biomass contained 18.6 % crude protein, was characterized by a balanced amino acid profile, and exhibited antioxidant activity (IC₅₀ DPPH = 0.84 mg/mL). Standardized cultivation conditions ensured reproducibility of the parameters. Model-based evaluation showed that inclusion of 1–5 % biomass in the diet may contribute to an increase in metabolizable energy and dry matter digestibility. Conclusions. Microclonal biomass of P. tomentosa can be considered a promising source of plant raw material for feed additives. The obtained results are of a predictive nature and require fur-ther experimental validation under in vitro and in vivo conditions.
