Four adult rams ($22.25{\pm}0.90kg$) were used in a $4{\times}4$ latin square design to evaluate the rations without ($T_1$) or with supplementation of sunflower acid oil at 5 ($T_2$), 10 ($T_3$) or calcium soap at 10% of dietary DM ($T_4$) on nutrient digestibility and balances of nitrogen, calcium and phosphorus. The basal ration contained 60 parts Brazilian napier grass hay and 40 parts concentrate mixture. The DM, CF, NDF and ADF digestibilities and nitrogen retention (g/d) decreased (p<0.01) by inclusion of sunflower acid oil at 5% of dietary DM. In addition, depression (p<0.01) in digestibilities of CP, nitrogen free extract (NFE), cellulose, hemicellulose, retention of calcium and phosphorus (g/d) were also observed with increasing the level of sunflower acid oil to 10% of dietary DM. The EE digestibility, total digestible nutrients (TDN) content and calcium retention (g/d) were significantly higher (p<0.01) for ration supplemented with calcium soap. It is concluded that sunflower acid oil supplementation in free form as low as 5% of dietary DM is deleterious to fibre digestion in sheep while as calcium soap, it can be fed up to 10% of dietary DM as an energy source without any adverse effect.

This study was carried out to investigate the effect of the feeding mixture of linesed oil, rich in n-3 PUFA and the sunflower seed oil, rich in n-6 PUFA on the lipid metabolism in the dietary hypprlidemic rats. After male Sprague-Dawley rats were induced hyperlipidemia by feeding the diet containing lard, butter, and cholesterol for 3 weeks, then they were fed with the diet containing lard 3.0% and butter 12.0% for control, the mixture in different proportion of both linseed oil and sunflower seed oil, and antihyperlipidemic durgs for 2 weeks. Analysis of the lipid component and the fatty acid composition of the liver showed following results. Concentration s of the total cholesterol and phospholipid in liver were significantly higher in group 2 (olive oil 12.0%) and lower in the other groups than in the control group, especially lower in groups 3 (cholestyramine 2.0%) and 9 (sunflower seed oil 12.0%) . Concentration of triglyceride was lower in the other groups except group 4 (liparoid), especially lowe rin group 9 than in the control group. In the fatty acid composition of liver lipids, C18:2 was the major fatty acid. Contents of n-6 PUFA increased , while those of n-3 PUFA decreased in groups composition of the test lipids. From the data on concentration s of total cholesterol. Phospholipid and triglyceride in liver, we concluded that the feeding mixed with 3.0% lard and 12.0 % sunflower seed oil were most effective for the improvement of the live lipids. The fatty acid composition in liver lipids were affected by the fatty acid composition of the test lipids.

After male Sprague-Dawley rats were induced hyperlipidemia by feeding the diet containing lard, butter and cholesterol for 3 weeks. then they were fed with the diet containing lard 3.0% and butter 12.0% for control, the mixture in different proportion of both linseed oil and sunflower seed oil, and antihyperlipidemic drugs for 2 weeks. Analysis of the fatty acid composition of the brain and heart lipids showed following results. In the fatty acid composition of brain lipids, C20:4 and C22:6 were the major fatty acids but showed little difference among the groups. In the fatty acid of heart lipids,C18:2 was the major fatty acid. The proportion of C20:4 decreased gradually as n-3P/n-6P ratio of the test lipids increased in groups 5 (linseed oil 12.0%) to 9 (sunflower seed oil 12.0%) while the proportion of C22:6 was not affected by the fatty acid composition of the test lipids.

Effects of lignan compounds (sesamol, sesamin, and sesamolin) extracted from roasted sesame oil on the autoxidation at $60^{\circ}C$ for 7 days and thermal oxidation at $180^{\circ}C$ for 10 hr of sunflower oil were studied by determining conjugated dienoic acid (CDA) contents, p-anisidine values (PAV), and fatty acid composition. Contents of lignan compounds during the oxidations were also monitored. ${\alpha}$-Tocopherol was used as a reference antioxidant. Addition of lignan compounds decreased CDA contents and PAY of the oils during oxidation at $60^{\circ}C$ or heating at $180^{\circ}C$, which indicated that sesame oil lignans lowered the autoxidation and thermal oxidation of sunflower oil. Sesamol was the most effective in decreasing CDA formation and hydroperoxide decomposition in the auto- and thermo-oxidation of oil, and its antioxidant activity was significantly higher than that of ${\alpha}$-tocopherol. Sesamol, sesamin, and sesamolin added to sunflower oil were degraded during the oxidations of oils, with the fastest degradation of sesamol. Degradation of sesamin and sesamolin during the oxidations of the oil were lower than that of ${\alpha}$-tocopherol. The results strongly indicate that the oxidative stability of sunflower oil can be improved by the addition of sesamol, sesamin, or sesamolin extracted from roasted sesame oil.

The aim of this study is to examine the radical scavenging activity of perilla and sesame oil that Koreans traditionally consume. For DPPH radical scavenging activity, oil and its hexane/70% methanol extracts (ME) are used and for superoxide and hydroxyl radical scavenging activities, ME are used. Unrefined perilla oil, sesame oil, and refined sunflower oil are used. The yields for ME of perilla, sesame and sunflower oil are 0.57, 0.61, and 0.30%, respectively, and the amounts of phenolic compounds in ME of corresponding oil are 18.77, 88.64 and $0.05\;{\mu}g$ tannic acid/mg, respectively. $IC_{50}$ for DPPH scavenging activity of perilla, sesame and sunflower oil are 2.12, 1.91, and 3.35 mg/mL, respectively and those for ME of corresponding oils are 0.42, 0.07, and 43.11 mg/mL, respectively. In DPPH assay, the solvent used for oil sample is iso-octane and that for ME is methanol. Superoxide anion scavenging activity of ME of perilla, sesame and sunflower oil tested at 1 mg/mL concentration are 21.10, 13.25, and 3.14%, respectively. Hydroxyl radical scavenging activities of those samples tested at 1 mg/mL concentration are 86.08, 93.30, and 93.17%, respectively. In summary, the refining process seems to remove the phenolic compound during oil processing. Antiradical substances in perilla and sesame oils responsible for scavenging DPPH radicals are present in the methanol fraction, while the antiradical substances in the sunflower oil are in the lipid fraction. DPPH scavenging activity of ME of sesame oil is significantly higher than that of perilla oil (p<0.05). However, superoxide anion scavenging capacity of ME of perilla oils was found to be greater than that of both sesame and sunflower oils (p<0.05).

This study aimed to investigate the effect of sunflower seeds, either as whole or as oil, on rumen fermentation, milk production, milk composition and fatty acids profile in dairy goats. Fifteen lactating Damascus goats were divided randomly into three groups (n = 5) fed a basal diet of concentrate feed mixture and fresh Trifolium alexandrinum at 50:50 on dry matter basis (Control) in addition to 50 g/head/d sunflower seeds whole (SS) or 20 mL/head/d sunflower seeds oil (SO) in a complete randomized design. Milk was sampled every two weeks during 90 days of experimental period for chemical analysis and rumen was sampled at 30, 60, and 90 days of the experiment for ruminal pH, volatile fatty acids (tVFA), and ammonia-N determination. Addition of SO decreased (p = 0.017) ruminal pH, whereas SO and SS increased tVFA (p<0.001) and acetate (p = 0.034) concentrations. Serum glucose increased (p = 0.013) in SO and SS goats vs Control. The SO and SS treated goats had improved milk yield (p = 0.007) and milk fat content (p = 0.002). Moreover, SO increased milk lactose content (p = 0.048) and feed efficiency (p = 0.046) compared to Control. Both of SS and SO increased (p<0.05) milk unsaturated fatty acids content specially conjugated linolenic acid (CLA) vs Control. Addition of SS and SO increased (p = 0. 021) C18:3N3 fatty acid compared to Control diet. Data suggested that addition of either SS or SO to lactating goats ration had beneficial effects on milk yield and milk composition with enhancing milk content of healthy fatty acids (CLA and omega 3), without detrimental effects on animal performance.
