ABSTRACT
The experiment was designed in a bifactor model with five maize hybrids (Rasant, Dragon, LG 2252, San and Magister), mowed at two heights, i.e., 10–12 cm (A) and 50 cm (B). The average yield of dry matter of plants cut at a height of 50 cm (B) was 130.5 dt/ha and was significantly lower than the yield obtained from maize mowed at a height of 10–12 cm (A), where it amounted to 148.1 dt/ha. The percentage of ears showed the opposite trend, with 55.3 and 49.2%, respectively. Dry matter in all silages ranged from 35.9 to 42.1%. B silages contained more dry matter and starch, but less structural carbohydrate. Dry matter degradation in the rumen of these silages was increased (65.5– 70.0%). Effective ruminal degradability of crude protein of all of the investigated silages (80.0– 86.5%) was in the same range as that of starch (79.2–87.3%). A tendency towards reduced protein and starch degradabilities was observed in B silages. The average NDF loss after 24 h of ruminal incubation of silage samples produced from plants mowed at the traditional height (A) was 65.3–66.7%.
