Abstract: According to Cornell Net Carbohydrate and Protein System (CNCPS) and in situ method were determined nutritional characteristics of crude protein (CP) in lucerne silage (LS) and maize silage (MS). Both LS and MS samples varied highly with concentrations in g.kg-1dry matter (DM): Crude protein (CP) 90.6 – 196.0 and 56.0 – 82.5 (P<0.05); neutral detergent fibre (NDF) 366.3 – 690.2 and 362.8 – 482.2; acid detergent fibre (ADF) 305.7 – 592.9 and 201.7 – 243.2 (P<0.01); acid detergent lignin (ADL) 43.7 – 77.2 and 23.8 – 29.2 (P<0.01), respectively. Concentration of B2 was significantly higher in LS than in MS (P<0.05). In situ effective CP degradability (ECPD) of LS and MS were similar (75.6 % and 76.3 %). Effective NDF degradability was higher for MS than for LS (36.5 % and 33.2 %) but the difference was not significant.
