Abstract
Ensiling of already ensiled beet with alfalfa on forage harvest time would produce a foodwith fibre and protein contents more suitable for dairy cattle feedstuff than the original sugar beetsilage. To study the effect of alfalfa moisture content on silage characteristics, alfalfa containing fourdifferent moisture levels (20, 30, 40 y 50%) was ensiled with previously ensiled beet using laboratorysilos (600 ml of capacity). All the mixtures were formulated to maintain the same proportion of bothcomponents in terms of dry matter (2/3 and 1/3 for alfalfa and beet dry matter, respectively). The pHvalues were lower than 4.5 at all moisture levels and, although small differences (P<0.05) in chemicalcomposition (crude protein, neutral detergent fibre and acid detergent fibre) between treatments werefound, moisture content had not effect (P>0.05) on in vitro digestibility of silages. Present work resultssuggest that moisture content of alfalfa has not any effect on silage quality.
