such silage was due to the pineapple fi ber having short fi brous particles and it usually had more digestible nutrients compared to hay and this may increase the rate of passage of feed particles. An increase in the rate of passage is associated with an increase in ADF digestibility (Guthrie and Wagner,1988). An increase in the amount of pangola hay in the silage ration would result in a decrease in the apparent digestibility of DM, OM, CP, NDF and ADF.
