Influence of the method of forage conservation on composition of silages and dairy cows performance

摘要

The silages were prepared on 2 June 1993 from the first cut of grass-clover mixture (15.1 % Lolium perenne, 15.2 % Lolium multiflorum, 10.0 % Lolium multiflorum v. oldenburgicum, 42.7 % Trifolium pratense, 10.2 % Trifolium repens, 6.8 % weeds). The sward was cut with forage harvester, wilted 24 h under good weather and conserved in big round bales (A) without additive, (B) with inoculant and (C) with formic acid (3 l/t, 85 %).
