Abstract
The purpose of the work was to assess the dynamics of energy and protein nutritional value of corn silage harvested from vegetable raw materials on the territory of the Republic of Tatarstan. The results of a retrospective analysis of the dynamics of metabolic energy, net energy of lactation, digestible protein in dry matter of 560 samples of corn silage taken in various agro-climatic zones of the Republic of Tatarstan in the period from 1993 to 2018 are presented. The research was car-ried out in the department of agrobiological research of the Tatar Scientific Research Institute of Agriculture, FRC Kazan Scientific Center, Russian Academy of Sciences. It was found that the con-tent of metabolic energy and net energy of lactation did not change during the study period. The long-term average value was 9.87 MJ / kg and 1.44 MJ / kg, respectively. Revealed the dynamics of increasing the content of digestible protein. The long-term average value of this indicator was 61.19 g / kg, which is 32.21 % higher than the norm.
