| Abstract: | By means of the respiration test technique the energy metabolism of adult pigs fed with a basic ration plus alfalfa leaves with 110-200 g crude fibre/kg DM was measured in 3 test periods. The digestibility of the energy of the alfalfa leave ranks amounted to--decreasing with increasing crude fibre content--66, 60 and 59%; the respective energy retention values were 7.5, 6.9 and 6.9 MJ NEFs or 510, 470 and 470 EFs/kg DM. According to the measured values there were no significant differences in the digestibility of the energy and in the energy concentration of NEFs between fresh and dried alfalfa leaves of largely equal chemical composition. |
