Abstract
The characteristics and feeding potential of corn distillers wet grains with solubles ensiled with corn stalks were evaluated in a 2-part experiment. Six individual batches of 66.7% distillers wet grains with solubles and 33.3% corn stalks (on an as-fed basis) were mixed and ensiled in 2 plastic silage bags. A set of 3 batches was left untreated (UNT), and the other set of 3 batches was treated (TRT) with a silage additive. Silos were sampled for analysis on d 0, 7, 14, and 21 after ensiling. The ensiling study was followed by a 6-wk randomized complete block design feeding study using 12 dairy heifers (initial BW of 213.8±3.03 kg) with 3 diets. Treatment diets were (1) control (CON) consisting of 30.3% grain mixture and 69.7% alfalfa and orchard grass hay, (2) 99% UNT blend and 1% mineral premix, and (3) 99% TRT blend and 1% mineral premix on a DM basis. In the ensiling study, blends were similar in DM, CP, ADF, pH, lactic acid, and acetic acid. In the feeding study, body frame measurements and ADG were similar among heifers fed all diets. Dry matter intakes were greater and G:F was less (P
