We investigated chemical composition, nutritive and energy value of maize silage, produced in 1993, 1994 and 1995, consumed by dairy cows on Mercator-Kmetijsko gospodarstvo Kočevje. In 1993 the maize silage was drought-stricken, therefore for that year also in vitro digestibility of dry and organic matter of two samples by drought differently stricken maize and of two samples of silage with different content of dry matter was stated. The content of dry matter of the analyzed samples of maize silage was the 275.8 and 362.4 g kg-1, with 252 and 254.7 g kg-1 of crude fibre and 6.38 and 6.41 MJ kg -1 NEL in it. The digestibility of dry matter was 0.664 and 0.660, while digestibility of organic matter was 0.657 and 0.652. The average of 6 samples of the analyzed silages produced in 1993 was 312.9 ± 19.9 g kg-1 of dry matter, and in it was 228.3 ± 13.1 g kg-1 of crude fibre and 6.54 ± 0.12 MJ kg-1 NEL. In vitro digestibility of dry matter of maize silage with 311.1 g kg -1 of dry matter was 0.665, and organic matter 0.657; in silage with 347.2 g kg-1 of dry matter the digestibility of dry matter was 0.666, and of organic matter 0.660. In silage produced in 1994 (n=8) the average content of dry matter was 362.9 ± 50.6 g kg-1, and it was 231.5 ± 18.6 g kg-1 of crude fibre and 6.43 ± 0.2 MJ kg-1 NEL. The analyzed silage produced in 1995 (n=5) contained 307.9 ± 26.3 g kg -1 of dry matter, in which was 238.1 ± 11.3 g kg-1 of crude fibre and 6.3 ± 0.12 MJ kg-1 NEL. Energy and nutritive values of silage produced in 1993, when the maize was stricken by drought, were actually lower than shown by calculation on the base of chemical analysis.
