Impact of Feeding Alkaline-Treated Corn Stover at Elevated Amounts in Commercial Feedlot Cattle

چکیده
compared to a 5% untreated stalk control (2013 Nebraska Beef Cattle Report, pp. 70-73). Treatment process in all of these university trials included 5% CaO (Mississippi Lime, StoverCalO, granulated quicklime) with 95% corn stalks (DM basis) and then mixed with enough water to produce a final mix that was 50% DM. No data are available using commercial treatment technologies and mixing and storing for seven days prior to feeding. Likewise, no data are available on commercial feedlot performance using alkaline treated stalks in place of a portion of corn. Therefore, the objective was to evaluate feedlot performance and carcass characteristics when 20% treated stalks were fed compared to a conventional control ration.

Effects of grind size when alkaline treating corn residue and impact of ratio of alkaline-treated residue and distillers grains on performance of finishing cattle.
Two studies were conducted to optimize use of alkaline-treated corn stover and wheat straw and distillers grains as partial corn replacements. In Exp. 1, a finishing experiment used 30 pens (12 steers/pen) of calf-fed steers (initial BW = 374 ± 23.9 kg) with a 2 × 2 + 1 factorial arrangement of treatments with 6 replications per treatment. Factors were grind size, where corn stover was processe...

Objectives were to evaluate the effects of replacing corn in feedlot finishing diets with processed corn stover (CS), processed by various combinations of chemical and physical methods, and modified wet distillers grain with solubles (MWDGS) on growth performance, carcass characteristics, digestibility, and ruminal metabolism of cattle. Corn stover was physically processed (ground or extruded) ...

and Implications Because treatment with calcium oxide (CaO) will increase the digestibility of corn stover, CaO-treated corn stover may be a cost-effective alternative to a portion of corn grain in beef feedlot diets. Single-pass harvested corn stover was ensiled either untreated or treated with 5% CaO on a dry matter (DM) basis. Ground baled stover, untreated stover silage, or CaO-treated stov...

Feedlot performance and mass balance were evaluated on steers fed either 5% untreated corn stover (CON), 20% untreated corn stover (NONTRT), or 20% calcium oxide (CaO) treated corn stover (TRT) when fed with or without saponins (Micro-Aid) in a 3x2 factorial. In both WINTER and SUMMER experiments, ADG, F:G and HCW were improved (P < 0.01) in CON and TRT fed steers compared to NONTRT fed steers....
متن کاملInfluence of Corn Particle Size on Steer Performance and Carcass Characteristics When Fed Diets with Moderate Inclusions of Wet Distillers Grains plus Solubles
and Implications A large pen study was conducted with a commercial feedlot to investigate the influence of corn particle size on performance of steers fed diets containing 35% (DM basis) wet distillers grains plus solubles (WDGS). Feedlot cattle in the Midwest are often fed distillers grains from ethanol production that are low in starch. Therefore, this study was designed to evaluate a practic...
