The objective of this study was to determine whether lipid peroxidation is one mode of action in ochratoxin A (OA) toxicity in vivo. Lipid peroxidation was monitored by analyzing malondialdehyde (MDA) in different tissues by HPLC. A refinement study on the MDA assay was carried out, which showed the importance of the addition of an iron catalyst for the decomposition of hydroperoxides to yield a maximum amount of MDA from a given sample. The rat experiment was designed in a 2 × 2 factorial arrangement using 4 × 6 animals. The four different diets were fed for 21 d and contained either 1% corn oil and 9% tallow (Diets I and III) or 10% corn oil (Diets II and IV); in groups III and IV, 5 mg OA were added per kilogram of diet. For the chick experiment 4 × 8 Leghorn cockerels received diets for 14 d with no added sunflower oil (Diets I and III), whereas the diets of groups II and IV were supplemented with 2.5% sunflower oil. In groups III and IV, 2.5 mg OA were added per kilogram of diet. In both experiments OA decreased the performance of the animals significantly. In the rat experiment an increased lipid peroxidation due to a higher dietary level of unsaturated fatty acids could be obtained, when muscle samples were oxidatively stressed with Fe3+ and ascorbic acid. In the chick experiment there were very clear effects of the dietary treatment on the MDA concentrations of different tissues, as both a higher supply with unsaturated fatty acids and OA increased most of the MDA values significantly. These data suggest that lipid peroxides are formed in vivo by OA, but the effects may vary considerably from species to species, and may also be influenced by other factors.

Studies were conducted on the use of oil obtained from rapeseed cultivar 'Podmoskovnyj' selection of Federal Williams Research Center of Forage Production and Agroecology in feeding broiler chickens. The experiments were carried out on chickens cross-country "ROSS-308". They were grown in a cell battery. For the experiment, 5 groups were formed. In the start and finish periods, the control group received 2.5 and 3.3% sunflower oil. In the experimental groups, sunflower oil was replaced with rapeseed in the following amounts: the first — 1.0 and 1.0%, the second — 1.5 and 1.7%, the third — 2.0 and 2.5% and the fourth — 2.5 and 3.3%. Feeding was carried out with dry loose feed from a day old. Studies have found that rapeseed oil had less saturated and polyunsaturated fatty acids, but more unsaturated fatty acids. The amount of erucic acid was 0.20%. The digestibility of nutrients was high and practically did not differ from the control variant, as was the use of nitrogen. The inclusion of rapeseed oil in the composition of feed for broilers did not have a significant impact on the increase in live weight and feed costs. The cost of feed with increasing rapeseed oil in their composition decreased, and the efficiency of converting feed into products increased slightly. Compound feeds with rapeseed oil were not inferior in terms of the efficiency of using compound feed containing sunflower oil.

Inclusion Level

The ME values of tallow, sunflower oil, soyabean, rapeseed and fish meals were determined by chick assay at various levels of dietary inclusion with both sexes. Female chicks metabolized significantly (P < 0.01) more energy from tallow and fish meal than did male chicks. Energy utilized from other feedstuffs tested did not differ between sexes. Less energy was available from tallow as its level of dietary inclusion increased; this could partly be due to altering the ratio of saturated to unsaturated fatty acids in the diet, leading to reduced absorption of palmitic and stearic acids present in tallow. There were significant interactions between sex of chicks and the levels at which tallow and fish meal were included in the diet. A possible interrelationship between the two feedstuffs in relation to the sex differences in absorption of dietary fat is discussed.

The study was aimed to evaluate the increasing levels of ration energy, with fat-rich unsaturated fatty acids from sunflower oil on the nutrient intake, rumen fermentability and performance of ewes. The experiment used fifteen ewes of 1.5 years old, primiparous, caged individually with their lambs and conducted three treatments and five replications from a completely randomized designed. Those treatments included R1= ration with 0% sunflower oil addition, R2= ration with 4%sunflower oil addition, R3= ration with 6% sunflower oil addition. The variables consisted of dry matter intake, nutrients, ewes performances (birth weight, weaning weight, decreased of body weight), total and partial VFA, the ratio of acetate: propionate, methane production, protozoa and bacterial population. Data were analyzed statistically and descriptively. The results showed that the treatments did not influence dry matter intake and nutrients,. rumen fermentability and ewes performances. Although the treatments increased (P<0.01) fatconsumption and reduced shrinkage of body weight. It can be concluded that the adding sunflower oil as the resource of unsaturated fatty acids up to 6% of the ration was not negatively affected the fermentability of rumen, moreover can improve ewes body condition and, accelerated body weight recovery

Temperature Storage

The oxidative state of sunflower oil during high-temperature storage has been facing large challenges. In the study, the antioxidant effect of the essential oil of Angelica dahurica cv. Yubaizhi (ADEO) in sunflower oil was explored. In the high-temperature storage for 24 days at 65 °C, ADEO (800 ppm) was able to markedly inhibit the development of the acid value (AV), peroxide value (PV), p-anisidine value (AnV), total oxidation value (TOTOX), thiobarbituric acid reactive substances (TBARS), total polar compounds (TPC), and the absorbance at 232 and 268 nm (p < 0.01 or p < 0.05) of sunflower oil and to prominently inhibit the transformation between unsaturated fatty acids (UFA) and saturated fatty acids (SFA). Interestingly, the synergistic effect of ADEO (400 ppm) and tert-butyl hydroquinone (TBHQ, 100 ppm) was demonstrated. Furthermore, the sensory attributes such as flavor, taste, and overall acceptability of oxidized sunflower oil added by ADEO at 200, 400, and 800 ppm were memorably elevated (p < 0.05). Besides, one of its main compounds, myrcene, was demonstrated to be its active compound during the whole investigation. Consequently, TBHQ at 200 ppm could be substituted by ADEO at 800 ppm and myrcene at 69.8 ppm in the high-temperature storage at 65 °C of sunflower oil.

Backfat Fatty Acid Profile of Crossbred Pigs Fed a Diet Supplemented with Conjugated Linoleic acid or Sunflower OilThe aim of the study was to investigate the impact of feeding pigs with different levels of conjugated linoleic acid (CLA) or sunflower oil (SFO) on the backfat fatty acid profile. The subjects of research were 60 crossbred gilts divided into 6 groups, which were fed different levels of conjugated linoleic acid or sunflower oil (0.5, 1.0 and 2.0%, respectively). All fatteners were kept and fed under standardized conditions. Animals were slaughtered at 95 kg of body weight. Fatty acid profile was determined in samples of backfat from each animal using gas chromatography. The significance of differences between groups was verified by Duncan's test. In the present study, a beneficial effect of adding CLA was that it reduced saturated fatty acids and increased unsaturated fatty acids in the adipose tissue (backfat) of pigs as compared to fatteners receiving SFO. The amount of monounsaturated fatty acids in the backfat decreased with increasing amounts of CLA or SFO. Modifying the fatty acid profile of pig backfat through addition of CLA or SFO would be beneficial to the health of consumers because relatively large amounts of fat pork, including backfat, are added to the sausages.
