Tests of efficiency of beet fodder in beef cattle feeding and as balance experiments lasting 309 days had shown that the average live weight increases in the category from 265,7 to 591,0 kg were 954 g in the A group (control), 1068 g in the B group (experimental), and 954 g in the C group (experimental). Highest live weight increases per animal unit and day were found in B group (1068 g), where 35.93 percent of SU (starch units) in the A group were supplied in the form of grain feed mixture with fodder beet. The live weight increases in the C group (17.97 percent beet ratio in the concentrate-based starch units of fodder) were 934 g, i.e. only slightly below those found in the control A group (954 g). The feeding experiment resulted in rational utilization of individual components in the fodder, as documented by the consumption of nutrients per incremental kg of live weight: 8,69 kg of dry matter (DM) in the A group, with 749,1 g DNS (digestible nitrogen substances) and 0,03 SU; in the B group, 7,85 kg of DM, 666,90 g DNS, 4,26 SU; and in the C group, 8,85 kg of DM, 796,60 g DNS and 5,03 SU.
