“…Thus, all considered perennial grasses can be traced regularity DM increase with the development of the vegetative phase, however, the figure in the rump and wheatgrass in the phase of earing and flowering has better balance in the vegetative parts, assessing their stern dignity. The explanation for this can be given to the influence of abiotic factors on the development of plants and individual characteristics (Maiti and Satya, 2014;Halford et al, 2014). This is especially true of wheatgrass, as the difference in accumulation of dry matter in culm and leaves was 6.8 and 3.5% at phase of earing and blooming, respectively.…”

The following grass: Brоmus inеrmis, Elytrígia bluish, Agropyron pectiniforme that are widely used in diets of ruminants were gathered and assessed for contents of Dry Matter (DM), Crude Protein (CP), ash, crude fat, Neutral Detergent Fibre (NDF), Acid Detergent Fibre (ADF), lignin, hemicellulose, Crude Fiber (CF), nitrogen-free substances. Samples of grain crops were assessed. The samples were taken within earing phase, flowering period, seeding in intact plant and in separate vegetative parts (n = 10). Dry matter regularly increases with developing vegetation phases. This index of smooth brome and wheatgrass has better balance in vegetative parts in earing and flowering phases during the assessment of their feed value. Mass weight of crude protein was in leaves and reproductive organs during all periods of plants development. At earing phase the highest content of it was registered. Higher content of crude fiber was registered in culm and leaves of smooth brome during earing phase. It was higher by 3.4-8.5%. The tendency for more intensive accumulation of crude fiber is observed rather well within seeding phase. Fiber content in culm of smooth brome was by 2.1-2.4% higher. Culm and leaves of wheatgrass in its turn have the highest content of nitrogen-free substances. With growth and development of crop neutral detergent fiber increases from 49.4% (in earing phase) up to 64.1% (in seeding phase) acid detergent fiber increased by 8.2-11.4% and hemicellulose and cellulose -by 0.7-4.4%. Concentration of metabolizable energy in 1 kg dry matter decreases by 17.3-19.7% in the process of physiological maturation of grain crops for feeding. Maximum content of structural carbohydrates was observed in culm part of grain crops, minimum content-in leaves and generative parts of plants had intermediate position. Thus, type of feed crop, phase of its development determine mainly chemical composition and content of carbohydrate fractions not only in whole grain crops but also in vegetative parts. It can further influence on preparation technology and fodder quality.

“…As the UK is one of the top importers of agricultural products (FAOSTAT ), changes in agricultural practices in other areas of the globe could have an impact on UK intakes. For instance, emerging crop selection research to find cultivars resistant to abiotic stresses, such as salinity or drought (Maiti & Satya ), could lead to changes in the nutrient profile of such crops. There is emerging evidence that the recent higher atmospheric carbon dioxide levels may impact on plant nutrient content, at least in wheat and brown rice, by increasing the proportion of carbohydrate, leading to a relative reduction in the content of other nutrients such as iron (Myers et al .…”

Micronutrient status and intake in the UK – where might we be in 10 years' time?

Poor dietary choices not only manifest in obesity, which is currently the main public health focus in the UK, but can also lead to inadequate micronutrient intakes, with implications for health. Recent dietary survey data and measurements of status biomarkers have highlighted folate, vitamin D, calcium, iron and iodine to be amongst the micronutrients of most concern for particular subgroups of the UK population. Those most vulnerable to inadequate intakes of these micronutrients include adolescents, ethnic minorities and lower socioeconomic groups. Teenage girls and women of childbearing age are of particular concern because of their high requirements for some micronutrients and the impact poor micronutrient intakes can have on the health of their offspring. Yet, compared to other food concerns, relatively little importance seems to be given by consumers to the micronutrient density of foods. This review explores different factors that may influence micronutrient intakes and status over the following decade and beyond. Over the next few years, it is likely that the micronutrients of concern remain similar, although continuation of dietary trends could result in further decreases in iron and calcium intakes. In an obesogenic and sedentary environment, where many people are being encouraged to reduce their energy intakes, increasing the micronutrient density of the diet is essential to prevent a concurrent decrease in micronutrient intake. Investment in fortification policies/practices or sustained government programmes aimed at raising awareness of micronutrients of most concern or encouraging supplementation, for example focusing on folate and vitamin D, could considerably improve population micronutrient intakes. Over the longer term, with sufficient investment in research and support from healthcare professionals and the food industry, adequate micronutrient intakes could be achieved across the UK population. However, global food security issues, including retaining food supply in response to an increase in demand for food, energy and water, and changing climate, could potentially hamper these efforts.

“…A produção é bastante variada em todo o mundo, principalmente, devido as distintas condições edafoclimáticas e do potencial genético das variedades e híbridos utilizados. Logo, a escolha do genótipo mais adaptado as condições locais, representa um fator determinante no rendimento sustentável, principalmente, em áreas propensas a condições ambientais desfavoráveis (MAITI & SATYA, 2014).…”

“…Atualmente, cerca de 20% das áreas agrícolas de todo o mundo apresentam produção limitada pelo excesso de sais na solução do solo (RIZWAN et al 2015). Isto ocorre sobretudo, nas regiões semiáridas e áridas que apresentam condições edafoclimáticas mais propícias ao aumento deste fator limitante (FAROOQ et al, 2009), que afeta aproximadamente 2/3 destas áreas (MAITI & SATYA, 2014).…”

“…A germinação e o crescimento das plântulas são considerados uns dos estádios mais sensíveis a este tipo de estresse abiótico (WATERWORTH et al, 2015). Portanto, a avaliação da tolerância, nestas fases mais críticas, permite a diferenciação de forma rápida e prática, como comprovado Maiti & Satya (2014), para identificação de acessos de sorgo mais tolerantes ao estresse salino, com potencial para ser utilizado em programas de melhoramento. IV INOVAGRI International Meeting, 2017 Esta pesquisa teve como objetivo avaliar a tolerância de três genótipos de sorgo granífero aos efeitos de distintos níveis de salinidade durante a germinação e crescimento das plântulas.…”
