dc.description.abstract Twelve ruminally cannulated crossbred steers were used to determine the effect of level of surface spoilage in corn silage-based rations on dry matter (DM) intake and nutrient digestibilities. Irrigated corn was harvested at the 80% milkline stage of maturity and ensiled in pilot-scale bunker silos, which were 3 ft in depth, and a 9-ft-diameter AgBag®. After 90 days, the bunkers were sealed with a single sheet of polyethylene, and this silage was designated “spoiled”. The silage in the AgBag was designated “normal”. The four rations contained 90% silage and 10% supplement (DM basis), and the proportions of silage in the rations were: A) 100% normal; B) 75% normal: 25% spoiled; C) 50% normal: 50% spoiled; and D) 25% normal: 75% spoiled. Dry matter intake decreased in a linear manner as the proportion of spoiled silage increased from 0 to 75%. Steers consuming the normal silage ration had higher DM, organic manner, crude protein, neutral detergent fiber, and acid detergent fiber digestibilities than those fed the three rations that contained spoiled silage. The addition of surface-spoiled silage also had negative associative effects on nutrient digestibilities, and the integrity of the forage mat in the rumen was destroyed partially by even the lowest level of spoiled silage. en_US
