This study aimed to describe the effects of the cooking condition, including water ratio (WR) and soaking time (ST), on the texture of rolled barley, and to evaluate its β-glucan content, total phenol content and in vitro starch digestibility. Rolled barley (75 g) was soaked in 1.5×, 2.0× and 2.5× weight of aliquots of Milli-Q water at room temperature, for 30 and 90 min, respectively, and then cooked using a rice cooker. Barley and rice were also pearled (polished), cooked and examined. The WR and ST did not affect the adhesiveness of rolled barley but were negatively related to its firmness. Rolled barley and barley had higher β-glucan and polyphenol contents and less starch hydrolysis during in vitro digestion than rice. The starch granules in rolled barley are enclosed by thick cell walls, which may be responsible for its firmness and low starch digestibility.

Barley grain sources with variable kernel sizes makes adequate and consistent processing of kernels challenging. This study evaluated how the severity of processing for reconstituted high-moisture (65% on DM basis) barley (RHB) affects ensiling characteristics and in vitro ruminal fermentation. Three independent sources of light (<630 g/500 mL) and heavy (>670 g/500 mL) barley were blended to create 4 sources of variable kernel sized barley (646 g/500 mL).

The objective of this study was to evaluate effects of increasing the inclusion of dry-rolled hybrid rye (HR) as a replacement for dry-rolled barley grain (DRB) on feed intake, ruminal fermentation, and the site and extent of nutrient digestion for finishing cattle. Eight ruminally and duodenally cannulated Hereford-cross heifers were used in a replicated 4 × 4 Latin square design with 21-d periods including 15 d of dietary adaptation and 6 d of data and sample collection. Dietary treatments included a control diet with 10.

The objectives were to compare cereal grain and straw yield between barley and hybrid rye () and to evaluate whether the inclusion of dry-rolled HR grain as a replacement for barley grain affected feed intake and growth for growing cattle, and feed intake, growth, and carcass characteristics for finishing cattle. Crop yield was measured by directly weighing harvested grain and straw bales ( = 3 plots/grain type). Three-hundred sixty steers with an initial body weight () of 348 ± 40 kg were stratified by BW and randomly assigned to 1 of the 24 pens during the growing phase ( = 8; 65 d).

Background: Using cover crops in organic vineyards can provide many advantages, including weed suppression. However, their effectiveness may depend on the weed community, the cover crop species and the termination method. The most common practice for cover crop termination is shredding, but rapid residue decomposition can allow noxious species like Cynodon dactylon to proliferate during summer and compete with the vines.

Background: The GlutenTox® ELISA Rapid G12 test kit is a quantitative method designed for the determination of the immunotoxic fraction of gluten in food samples.
Objective: To obtain AOAC Performance-Tested MethodsSM certification for the method for the detection and quantification of gluten from wheat, barley, and rye flours in select foods (non-heat-processed) and incurred (heat-processed) matrixes.
Methods: The method was evaluated following the Guidelines for Validation of Quantitative Gluten Methods, with Specific Examples for ELISA Assays.
