Аннотация: The optimal density of larvae in Siberian moth (Dendrolimus superans sibiricus) kept in chambers varied in ontogenesis: the larvae living in grups predominated in the I-st-IVth instars, whereas those living alone, in the VIth instar. The critical moment equalizing feeding and growth parameters in single larvae and those grown in groups was observed in the V-th instar. The larval aggregation favored the survival rate in the I-st-IIIrd instars and the developmental intensity in the IIIth-IVth instars due to the higher efficiency of using food (ingested and digested) for growth. The relative growth rate and digestibility of food did not depend on the density of larval populations. The effects of density on feeding and growth parameters, as well as on the survival rate, were displayed even when three larvae were kept in one chamber. The increase of the number of larvae up to 20 did not change these effects.

Аннотация: Today, plant waste, including fallen poplar leaves (litter), are a promising raw material for the production of useful prod-ucts using bioconversion, such as protein feed additives. The aim of this study was to study the component composition of the products obtained as a result of the bioconversion of leaf litter. The strain PP-3.2 Pleurotus pulmonarius (Fr.) Quel. In the process of substrate conversion, strain PP-3.2 primarily utilizes extractives and easily hydrolyzable polysaccharides, the amount of which decreases by 44 and 36%, respectively. The total content of polysaccharides is reduced by 20%, lignin substances-9.4%. The loss of substrate mass based on leaf litter was 23%. The product obtained after cultivation contains 28% protein. Analysis of the amino acid composition of the protein showed a high rate of phenylalanine with tyrosine (115), threonine (117.5), valine (110) and isoleucine (105%). Also, the biodegradation product has a high content of glutamic and aspartic acids (11.2 and 25.3% of the total amino acids, respectively). The levels of cadmium, lead and copper revealed as a result of studies do not exceed the maximum permissible concentrations established by the veterinary department. At the same time, there is a high content of iron (166.0 Eg/kg) and zinc (256.7 mg/kg) in the feed product. The digestibility of the product is 54%, the content of nucleic substances is up to 0.3%. Thus, the results obtained show the possibility of using the product of the conversion of poplar fallen leaves as a protein feed additive. © 2021 Altai State University. All rights reserved.
