Abstract
The biochemical and mineral composition, nutritional and energy value of Leymus chinensis in the steppe zone of Eastern Transbaikalia, growing in different soil and ecological conditions, due to the lack of data on these indicators, has been studied. For the first time, the content in dry matter of Leymus chinensis crude protein, sugars, crude fat, crude fiber, nitrogen-free extractive substances, feed units and metabolic energy and its mineral composition was studied. The dependence of the accumulation of nutrients on soil-ecological conditions, the duration of the growing season and the phase of plant development, the adaptive adaptation of this species to prolonged aridization, which causes its vegetative reproduction due to a decrease in generative reproduction, has been established. The protein ratio as an indicator of feed digestibility is characterized as broad (1 : 9.9–15). The amount of digestible nutrients varied in a very narrow range (592.5–602.2), as well as the energy content (10937.6–11116.6 kJ) and metabolizable energy in the food (9187.6–9337.9 kJ), which is associated with a short vegetation period of L. chinensis development in the sharply continental climate of the steppe zone of Eastern Transbaikalia. A specific feature of the mineral composition of this cereal was the high amount of S, as well as the K: Na ratio (7–38) at the norm of 3–5.
