ABSTRACT
Amino acid composition, in situ ruminal degradation and intestinal digestion of dry matter
(DM), crude protein (CP) and individual amino acids (AA) of fresh and ensiled galega (Galega
orientalis Lam.) were determined and their nutritional value calculated according to INRA (1988).
Total AA (Trp excluded) in forage (1stcut, budding) was 81.3 g/16 g N, decreasing to 71.3 g/16 g N
in wilted silage + Kemisile2000 (4 l/ton). The in situ degradation coefficients (k=0.06) for CP and DM
in galega forage were higher than in silage (69.5 and 64.4 vs 56.4 and 45.1%); similar relationships
were found for total AA degradation after 16 h incubation in the rumen (87.4 vs 66.9%). The mobile
nylon bag intestinal digestibility of CP, total AA and DM in wilted silage vs forage was 61.5 and
68.2; 71.6 and 74.2; 21.1 and 23.5%, respectively. The content of PDIA, PDIN and PDIE in galega
fodder was slightly higher than in lucerne forage and silage; the energy values were close.
