Fatty acid composition of oilseeds of Guizotia abyssinica, Medeya cultivar

The Penza Institute of Agriculture has created Medeya cultivar of Guizotia abyssinica , which has been included in the State Register of Breeding Achievements since 2019 and is recommended in all regions for cultivation. The cultivar has ecological plasticity, is characterized by resistance to drought and high temperatures, as well as high responsiveness to additional moisture. It differs in stable seed productivity and high fat content. The aim of the research is a comparative assessment of the fatty acid composition of oil seeds of Guizotia abyssinica grown in contrasting agroclimatic regions. The object of study was the seeds of G. abyssinica grown in different soil and climatic conditions of the Penza, Astrakhan, Tambov and Volgograd regions. The article presents the results of changes in the content of oil and fatty acids, depending on weather, soil and geographical conditions of growth of the culture. The fat content in the seeds of G. abyssinica varied from 33.3-39.2%, depending on agro-climatic conditions. The rich chernozem soils of the Penza and Tambov regions have a fat content of 36.7 to 39.2%, respectively. In the Volgograd region on chestnut soils, the oil content of the seeds of G. abyssinica was 33.3-35.7 %. The main component of the fatty acid composition of the oil of G. abyssinica is polyunsaturated fatty acid - linoleic, the content of which reaches a high value of 79.17%. The content of oleic acid is low and is 5.26%, and linolenic 1.21%. There is no erucic acid in the seeds. The maximum content of linoleic acid (77.5-80.0%) is noted in oilseeds grown on the black soil of Penza and Tambov. The content of linoleic acid was highest in the optimally wetted conditions of 2016 (GTK 1.1) - 79.17%. In arid conditions, with GTK 0.3, the concentration of this acid significantly decreased to 74.36%. The content of palmitic and stearic acids in GTK 1.1 was 7.82 and 5.80 %, in GTK 0.8, their values reached 7.96 and 5.93 %, and in GTK 0.3 - 8.22 and 7, 91%, respectively. Hotter and drier conditions during the vegetation period of hydration contribute to an increase in saturated acids and a decrease in linoleic acid.

ObjectivesThe objective of this study was to determine the effects of feeding chestnuts and acorns on growth performance, carcass quality and further processed products of Duroc/Duroc crossbred finishing barrows.Materials and MethodsBarrows (n = 30) were individually housed in pens, blocked by body weight and randomly assigned to one of three treatments: control (n = 10), inclusion of acorns at 15% of the diet (n = 7), inclusion of chestnuts at 15% of the diet (n = 13). Pigs were fed ad libitum for 28 d prior to harvest. Feed refusal and individual pig weights were collected every 7 d and used to calculate average daily gain (ADG), gain-to-feed (G:F), and average daily feed intake (ADFi). Following harvest, carcass quality was determined by objective color (L*, a* and b*), fat composition and marbling scores. Fat samples were removed from four fat depots (backfat, seam, jowl, kidney and pelvic) and analyzed for fatty acid composition. Sample chops were removed between the 10th and 11th rib of the left side of each carcass and analyzed for fatty acid composition, moisture and fat content. Bellies were removed from the left side of each carcass, further processed into bacon slabs and analyzed for slice quality, fatty acid composition, moisture and fat content. Carcass characteristics and bacon quality were analyzed using GLM procedure of SAS. Growth performance and fatty acid composition were analyzed using MIXED procedure of SAS. Significance was determined at P-value < 0.05.ResultsNo differences were detected for ADG and ADFi across treatments (P > 0.05). Barrows fed chestnut diets had a greater G:F when compared to control (P < 0.05) or acorn fed barrows (P < 0.05). Dietary treatments did not impact (P > 0.05) carcass characteristics or carcass quality. Inclusion of chestnuts or acorns within the diet did not impact (P > 0.05) moisture and fat content of chops and bacon slices (P > 0.05). Moreover, feeding acorns led to similar concentrations (P > 0.05) of palmitoleic acid (16:1) and linoleic acid (18:2n6c) when compared to the control diet. However, feeding diets containing acorns led to greater proportions (P < 0.01) of palmitoleic acid and linoleic acid similar to barrows fed diets containing chestnuts. No difference (P > 0.05) for stearic acid (18:0) were observed between control and chestnut treatments, however, both were found to have greater amounts (P < 0.01) of stearic acid when compared to the acorn treatment. Acorns increased (P < 0.01) the total concentration of omega-6 fatty acids (n-6) when compared to chestnut diets, but no differences (P > 0.05) were observed between acorn and control diets. Inclusion of acorns reduced (P < 0.05) total saturated fatty acids (SFA) when compared to control and chestnut treatments; however total polyunsaturated fatty acids (PUFA) were increased (P < 0.05) when acorns were included in the diet. When evaluating PUFA:SFA ratio, no differences (P > 0.05) were found between control and chestnut diets. Including acorns in the diet, resulted in an increased (P < 0.05) PUFA:SFA ratio.ConclusionInclusion of acorns and chestnuts did not negatively impact carcass characteristics, carcass quality or bacon quality, nevertheless, including acorns altered overall fatty acid composition while minimal differences were observed between diets containing chestnuts and the control.

The results of long-term studies of the biological, morphological and phenological features of the introduced new culture of safflower in the Central, Volga and North Caucasus regions are presented. Optimum parameters of depth of seeding (5-6 cm), seeding rates (300-350 thousand pieces/hectare or 12-14 kg), ensuring high productivity, oil content and quality of seeds are established. For the first time, the relationship between moisture availability of vegetation periods with accumulation of oil content and a change in the fatty acid composition was established. Oilseed (in untreated seeds) in the regions was from 14,5 to 31,2%, in excessively wet 2013 – 6,4% in the Moscow region and 8,6% in the Saratov region. Fatty acid composition revealed a high content of oleic acid in Krasa Stupinskaya variety – 13,6-16,8%, linoleic acid – 68,5-75,7%. The yield of oil in the Moscow region was 240 kg/ha. The yield of Krasa Stupinskaya in the Moscow Region was 0,6 t/ha, the Rostov Region 0,8 t/ha and Saratov Region 1,2 t/ha, with an average weight of 1000 seeds, respectively, by regions: 40,0 g, 47,3 g and 40,9 g. The growing season for growing seeds was 105 days in the Moscow Region, 94 days in the Rostov Region and 95 days in the Saratov Region. It has been established that excessive moistening during the flowering and seed filling period increases the harmfulness of enzyme-mycosis seed depletion (EMIS) – biological injury during maturation (enzymatic stage), followed by the seeding of the seeds with the phytopathogen Alternaria carthami Chowdhury. In the breeding programs for productivity and oil content, it is recommended to use the varieties Moldir (Kazakhstan) and Krasa Stupinskaya (FGBNU VSTISP), the fatty acid composition of which is characterized by an increased content of oleic and linoleic acid, which is of particular value for storage and use for food purposes.

Fatty Acids Profile

The effect of the stage of lactation, the number of foals and age of the mare on changes in the fat content and fatty acid composition of colostrum and milk of primitive Konik horses was investigated. Colostrum and milk samples from 12 lactating mares were collected at the beginning of lactation, on the days 1 and 2 after foaling and then, starting from the first month of lactation, at 4-week intervals up to the sixth month of lactation. Significant differences were observed in fat content as well as the composition of some analysed fatty acids between colostrum and milk of mares of the Konik breed. The number of foalings and the age of mares did not have a statistically significant effect on the fat content in milk and had only a slight effect on the fatty acid composition. Milk produced by mares of the Konik breed is characterized by a considerable content of polyene fatty acids with 18 carbon atoms, a low ratio of n-6 fatty acids to n-3 fatty acids as well as low, highly advantageous values of atherogenic and thrombogenic indices.
