“…Barley oil is recognized as potential functional oil (Lupton, Robinson, & Morin, 1994;Qureshi, Burger, Peterson, & Elson, 1986), mainly due to the abundance of tocotrienols (Wang, Behr, Newman, & Newman, 1997). Although barley is not a rich source of oil compared to other cereals such as oats and maize, barley oil plays an important role due to the nutritional value of its products, particularly animal feed, thus generating a demand for genotypes with high lipid profiles (Bleidere & Gaile, 2012;Juskiw, Helm, & Salmon, 2011). It has been shown that when barley is milled by various methods, some of its milling fractions are enriched in lipids and the levels of tocotrienols were improved (Munck et al, 2010;Nielsen & Hansen, 2008).…”

Background and objectives: Vitamin E is an important dietary component found mainly in plants and is a group of compounds including tocopherols and tocotrienols, collectively known as tocols. In this study, tocols and oil content was evaluated in whole grain, brewer's spent grain, and pearling fractions from various barley genotypes grown at two sites in 2014, and at three sites in 2015 in Manitoba, Canada. Findings: Mean tocols and oil content was much higher in brewer's spent grain than in whole grain of malting genotypes. Pearling fractions had higher tocols and oil content than whole grain of six distinct feed/food genotypes, with the highest tocols and oil content observed in the 5%-10% pearling fraction. Conclusions: Brewer's spent grain and the 5%-10% pearling fraction could be used as novel functional food ingredients or be valuable sources for extraction of health-promoting tocols and/or oil. Significance and novelty: Using barley processing by-products like brewer's spent grain and pearling fractions in value-added products with beneficial health properties may offer unique economic and waste management opportunities. A relatively large number of malting and feed/food barley genotypes were screened for all eight tocol vitamers and oil content. This study serves as a valuable resource for barley research scientists and the barley industry as a whole. K E Y W O R D Sbarley, brewer's spent grain, oil, pearling fractions, tocols, vitamin E

“…When producing barley for brewing, the size and uniformity of the grains influence the quality of the final product . Indeed, malting quality reflects the interaction of characteristics that meet the specifications required for brewing which include malt extract, protein content and β‐glucan .…”

Genetic variability of irrigated barley in savanna environments based on malting quality

et al. 2020

The Brazilian savanna has the potential to support the national demand for barley providing an opportunity to the agricultural business in the region. The barley breeding program of Embrapa Cerrados pursues the selection of superior genotypes, adapted to the savanna conditions, with industrial quality and high grain yields. This work sought to characterise and quantify the genetic variability of 38 elite genotypes of irrigated barley in the Brazilian savanna from industrial grade traits, verifying the degree of association between quality characters and analysing the genetic distance from the ideotype. Twelve traits of malting quality were evaluated in two environments of the Distrito Federal. A descriptive analysis of the data was performed, the genetic dissimilarity coefficients were estimated between each genotype pair based on the Mean Euclidean Distance, the genotype-ideotype distance index, the Pearson correlation and the relative contribution of each trait to Singh's genetic diversity of evaluated traits. There were dependency relationships between malting traits for the evaluated environments. Such associations facilitate the indirect selection of genotypes, increasing the efficiency of the breeding program. The use of selection indices allows the choice of promising genotypes that can be explored in blocks of crosses to maximise heterotic effects and genetic complementarity in the genetic breeding program of irrigated barley in the Brazilian savanna.Additional supporting information may be found online in the Supporting Information section at the end of the article.Genetic variability of irrigated barley in savanna environments based on malting quality

“…Cereal grains are the major contributor for energy and protein for most feed diets (Bleidere & Gaile, ; O'Doherty, McGlynn, & Murphy, ) with barley being one of the major feed ingredients included in swine diets primarily as an energy source (Fan, Han, Xu, Wang, & Shi, ; Li, Feng, Xu, & Yang, ). Agronomical conditions can affect chemical composition of cereal grains, affecting their energy, crude protein (CP), fibre and starch (Conan, Metayer, Lessire, & Widiez, ; Longstaff & McNab, ; Metayer, Grosjean, & Castaing, ).…”

This study investigates the effect of dietary supplementation of a β-glucanase and β-xylanase enzyme mix to barley based diets, at two different chemical compositions achieved through different agronomical conditions on growth performance, coefficient of apparent total tract digestibility (CATTD) of nutrients, selected faecal microbial populations and faecal scores in piglets. Sixty-four piglets (11.7 kg (SD 0.96)) housed in pens of two were assigned to one of four dietary treatments (n = 8). The dietary treatments were as follows: (T1) low quality barley diet, (T2) low quality barley diet containing a β-glucanase and β-xylanase enzyme supplement, (T3) high quality barley diet and (T4) high quality barley diet containing a β-glucanase and β-xylanase enzyme supplement. Piglets offered the low quality barley-based diet had a higher (p < .05) average daily gain (ADG) (0.73 vs. 0.69 kg, SEM 0.001), gain:feed (G:F) ratio (0.61 vs. 0.58 kg, SEM 0.011) and a higher CATTD (p < .001) of dry matter (DM), organic matter (OM), nitrogen (N), ash, gross energy (GE) and neutral detergent fibre (NDF) compared with piglets offered the high quality barley diet. Piglets offered the high quality barley-based diet had reduced faecal scores compared to piglets offered the low quality barley-based diet (2.44 vs. 2.57, SEM 0.036) (p < .05). There was a higher population of Lactobacillus spp. (11.6 vs. 10.5 log gene copy number/g faeces, SEM 0.177) (p < .001) and total volatile fatty acid (VFA) concentration (185 vs. 165 mmol/g faeces, SEM 5.658) (p < .001) in the faeces of piglets offered the high quality barley-based diet compared to piglets offered the low quality barley-based diet. The inclusion of a β-glucanase and β-xylanase enzyme complex had no effect on any variable measured. In conclusion, the higher quality barley-based diet showed beneficial effects on the faecal Lactobacillus spp. population and faecal scores of the piglets; however, the higher level of β-glucans in the diet decreased nutrient digestibility and subsequently decreased the performance.
