Silage and milk production: comparisons between grass silage of three different chop lengths



Silage and milk production: comparisons between grass silage of three different chop lengths



Grass and Forage Science 34(4): 293-301



3 grass silages of different chop lengths made from a uniform sward of perennial ryegrass S23 were compared in 4 experiments including a feeding experiment with 12 lactating cows, an eating behaviour study, a rate of passage investigation and a selection trial. The silages had medium chop lengths of 9.4, 17.4 and 72.0 mm, with pH values of 3.93, 3.94 and 4.17 and D-values of 65.9, 65.2 and 64.4, resp.
