“…В 100 кг зерна содержится 118-120 кг кормовых единиц. В зерне находятся 17 незаменимых аминокислот, витамины (Е1, В1, В2, В3, каротин), минеральные вещества (Р2О5, К2О и MgО), танины (дубильные вещества), по своему действию являющиеся аналогами витамина Р, так как укрепляют стенки кровеносных сосудов [8,9,10,11,12,13]. Оценка эффективности использования зернового сорго сорта Рось в составе комбикормов-концентратов для лактирующих коров была проведена в СПК «Заветы Ленина» Нефтегорского района Самарской области.…”

The Lugansk region is situated in the arid steppe part, where the main grain crops are not able to realize productive potential to their full extent. The purpose of the work is to identify the features of grain sorghum varieties developed by the FSBSI ARC “Donskoy” in the conditions of the Lugansk region. The objects of the study were the sorghum varieties ‘Orlovskoe’, ‘Zernogradskoe 88’, ‘Luchistoe’, ‘Velikan’, ‘Khazine 28’ developed by the FSBSI ARC “Donskoy” in comparison with the varieties and hybrids of exotic breeding. The ecological study was conducted in the experimental plot of the Lugansky National Agricultural University in 2016–2017. The varieties selected by the ARC “Donskoy” belong to the groups of ultra-early season and early season varieties and become completely mature for 83–96 days. The productivity of the varieties ‘Orlovskoe’, ‘Luchistoe’, ‘Velikan’ is similar to the productivity of varieties and hybrids which mature on 20–25 days later. The varieties manage to form high-grade grain to mid-September and do not need any costs on desiccation of sowings and drying of grain after harvesting to conventional humidity that testifies high economic efficiency of the ARC “Donskoy” varieties. Grain productivity is a complex trait, which consists of various quantitative elements. The conducted structural analysis showed that plant height, 1000-kernel weight, grain nature of the most varieties and hybrids had week correlation with external conditions. According to the correlation-regression analysis grain nature in the Lugansk region is directly connected with sorghum productivity. The increase of grain nature on one unit results in grain productivity increase on 0.0091 t/ha.

Influence of extrusion on the feed value of flax seeds

2021

Relevance. The wide use of extrusion for processing plant raw materials is explained by the possibility of improving the structure and increasing the availability of macronutrients of the target product. Extrusion of oilseeds is complicated by the negative effect of high lipid content on the ongoing physicochemical processes and, as a consequence, a decrease in the quality of extrudates. Along with their high lipid content, oilseeds such as flaxseed contain significant amounts of protein, soluble (mucilage) and insoluble (cellulose, lignin) fibers, which can also affect the technological properties of extrudates. As a high-energy and protein component, flax seeds are used in the feed industry. Increasing the nutritional value of flax seeds and their safety will expand the range of biologically active additives for the production of feed. The purpose of this work is to study the effect of extrusion on the feed value of flax seeds.Methods. For the research we used unmilled oil flax seeds produced in 2020. Flax seeds were processed by wet extrusion: the raw material was preliminarily moistened to 17% at 80 °C; extrusion process parameters — 120 °С, pressure 40 atm., duration 30 sec. Extruded flax seeds were obtained on a pilot plant of OOO “Fid-Group” (Belgorod region). Studies of extruded flax seeds were carried out on the basis of the laboratory for processing bast crops of the Federal Scientific Center for Fiber Crops (Tver).Results. A comparative analysis of the results showed a positive effect of short-term barothermal treatment, such as extrusion, on the chemical composition of flax seeds and their feed parameters. It has been shown that: the content of crude protein in extruded flax seeds increased by 3.97%, the water-soluble fraction increased by 66.18%, which indicates an increase in the biological value of the extrudate; the mass fraction of crude fiber decreased by 1.18%, which indicates an improvement in the digestibility of the extruded product; the content of mineral nutritional value increased by 12.5%; when using barothermal treatment, the nutritional value of flax seeds increased by 2.46%, metabolic energy increased by 2.19% and digestible protein increased by 4.08%; the level of indicators of the lipid complex, acid number and peroxide number, decreased by 40 and 39% respectively, which indicates a decrease in the activity of enzymes that cause hydrolytic and oxidative deterioration of the extrudate.
