چکیده

Effects of barley starch:NDF ratio and DDGS inclusion on feedlot performance, carcass characteristics, and N and P mass balance were evaluated in a commercial feedyard in Alberta, Canada. Yearling heifers were assigned randomly at reimplant to four treatments (0 or 20% DDGS and LOW or HIGH starch:NDF barley). Feeding LOW starch:NDF barley improved feedlot performance and increased N retention. Feeding 20% DDGS increased DMI, had a slight negative impact on F:G, and increased N and P losses.

Wheat distillers grains in feedlot cattle diets: feeding behavior, growth performance, carcass characteristics, and blood metabolites.

A study was conducted to evaluate feed intake, ADG, carcass quality, eating behavior, and blood metabolites in feedlot beef steers fed diets that varied in proportion of wheat dried distillers grains with solubles (DDGS) replacing barley grain or barley silage. Two hundred crossbred steers (BW = 489 ± 30 kg) were blocked by BW and randomly allotted to 20 pens (5 pens per treatment). Steers were...

Using a fibrolytic enzyme in barley-based diets containing wheat dried distillers grains with solubles: ruminal fermentation, digestibility, and growth performance of feedlot steers.

Two experiments were conducted to evaluate the effects of adding an exogenous fibrolytic enzyme (FE) on ruminal pH and fermentation, digestibility, and growth performance of feedlot beef cattle fed a finishing diet containing wheat dried distillers grains with solubles (DDGS). In Exp. 1, 4 ruminally cannulated Angus heifers (average BW of 807 ± 93.9 kg) were used in a replicated 4 × 4 Latin squ...

Effects of wheat or corn distillers dried grains with solubles on feedlot performance, fecal shedding, and persistence of Escherichia coli O157:H7.

Distillers dried grains with solubles (DDGS) are a coproduct of the ethanol industry and are often used as a replacement for grain in livestock production. Feeding corn DDGS to cattle has been linked to increased fecal shedding of Escherichia coli O157:H7, although in Canada, DDGS are often produced from wheat. This study assessed the effects of including 22.5% wheat or corn DDGS (DM basis) int...

Distillers Grains with Solubles for Feedlot Cattle - Finishing Performance, Lipid Metabolism, and Ethanol Greenhouse Gas Balance

Feedlot cattle performance data from 20 trials (n = 350 pen means; representing 3,365 steers) evaluating dietary inclusion of corn wet distillers grains plus solubles (WDGS) were summarized with two meta-analyses. The objective of this study was to evaluate the effects of WDGS inclusion level with dry-rolled corn (DRC) or a blend of DRC and high-moisture corn (HMC) for either calf-feds or yearl...

Ruminant Nutrition: Rumen Fermentation Modifiers

The objective of this study was to evaluate the effects of Rumensin and Tylan in feedlot diets containing wet distillers grains plus solubles. Eight hundred beef steers (329 ± 25 kg) were blocked by initial BW and randomly assigned to one of five treatments (20 steers per pen, 8 pens per treatment). Treatments consisted of a corn-based diet with Rumensin and Tylan (CORN+RT) and four treatments ...
