Effects of increasing soybean hulls in finishing diets with wet or modified distillers grains plus solubles on performance and carcass characteristics of beef steers

“…1 and Exp. 2, these feeding values reported by Bremer et al (2011) decreased as inclusion increased. In Exp.…”

“…With input variables of diet composition, initial BW, final BW, ADG, and DMI known, the energy value of SBH relative to corn was calculated for each pen. Total digestible nutrients were assumed to be 90% for corn (NRC, 1996), 72% for corn silage (NRC, 1996), and 112.5% for MDGS (Bremer et al, 2011) in all diets. The NE adjusters for the 0% SBH diet were adjusted to equal the observed ADG for that treatment.…”

“…1. Total digestible nutrients were assumed to be 90% for DRC (NRC, 1996), 93% for high-moisture corn (NRC, 1996), 60% for sorghum silage (NRC, 1996), and 117% for WDGS (Bremer et al, 2011) in all diets. The NE adjusters for the 0% diet were adjusted to equal observed ADG for that treatment.…”

Changing distillers grains: implications for cattle performance and management

“…Because the nutrients in corn are concentrated into DG, the feeding value, defined as the percentage change in feed conversion (Bremer et al, 2011b), of DG is greater in relation to corn. In a meta-analysis by Bremer et al (2011b), the feeding value of DG at 20%−40% dietary inclusion ranged from 110%−145% of the corn which DG replaced.…”

“…The decreased ability of cellulolytic bacteria to digest fiber has been shown to decrease feed intake and overall performance of feedlot cattle (Zinn, 1989a). Because DG contain a higher proportion of unsaturated fatty acids compared to corn oil, when dietary fat is sourced from DG instead of corn oil, performance is not as negatively affected Bremer et al, 2011b). Fat source, supplemental fat concentration, and particle size are components that suppress fiber digestion and rate of fermentation in the rumen, but the severity of fiber inhibition varies.…”
