Current study contains the comparison of the ensilage of white melilot unmixed sowing and the sweet clover-ryegrass green mass as well as on feeding them to cattle. The green mass in the big bale was well fermented, no undesired organic acids (butyric acid, propionic acid) were detected during analysis. The dry matter content of the silage was 21...22 per cent. The ensilage of the unmixed sowing melilot provided for the silage with a high protein content (15.6 per cent) which also contained a lot of crude fibre (32.6 per cent). The digestibility of the melilot silage's (56 per cent) and its nutritive value (8.7 MJ kg sup(-1) were satisfactory. The protein content of the melilot-ryegrass mixed silage was lower (12.5 per cent), but the nutritive value higher (9.2 MJ kg sup(-1). The results of the feeding experiment indicated the plausible (P0.05) superiority of the melilot-ryegrass silage over the melilot silage. The feeding ration of the animals that received the mixed silage was insufficient with regard to energy (94 per cent) of which silage was responsible for 63 per cent. The ratio of energy and protein content remained unbalanced (ME 89 per cent and DP 11o per cent) in the feeding ration with the melilot silage. The consumption of the melilot-ryegrass was good (12.8 kg DM) and plausibly better (P0.05) than that of the melilot silage. That resulted also in the plausibly better (P0.05) milk production (FCM 28.2 kg d sup(-1)). The production of the milk protein and the milk fat were also higher in feeding the melilot-ryegrass silage
