FIELD: agriculture.
SUBSTANCE: energy value is determined based on the calculation of the activation energies of chemical components as the sum of the activation energies of the grain cover and core of white lupine, multiplied by the mass fraction of the cover and core in the grain, respectively. To calculate the activation energy the data of thermogravimetric and differential-thermal analysis are used, obtained in continuous heating of samples at a rate of 20 deg/min to thermal decomposition of the components of the grain cover and core.
EFFECT: invention enables to estimate fast and accurately the energy value of feed white lupine grains for feeding farm animals.
