  • Growth studies of Catenaria anguillulae isolates in response to sodium chloride indicated that all the isolates grew in linseed oil-cake agar medium containing sodium chloride up to 1.0%. Medium with 1.5% sodium chloride, however, completely checked the growth of all the isolates. The size of zoosporangia greatly increased with abundant zoospore production in medium containing sodium chloride at 0.5%.

  • The present study was conducted to determine the effects of lipid sources with different fatty acids profile on meat fatty acids profile and beef quality traits of Nellore. A total of 45 Nellore animals with an average initial body weight of $419{\pm}11kg$ (at $15{\pm}2mo$) were distributed in a completely randomized design consisting of 5 treatments and 9 replicates. The roughage feed was maize silage (600 g/kg on a dry matter [DM] basis) plus concentrate (400 g/kg on a DM basis). The dietary treatments were as follows: without fat (WF), palm oil (PO), linseed oil (LO), protected fat (PF), and soybean grains (SG). No effects of lipid sources were observed (p>0.05) on beef color, pH, water-holding capacity, and sarcomere length. Beef from cattle fed PO had greater shear-force values (p<0.05) compared to beef from cattle fed WF. Deposition of main unsaturated fatty acids (oleic, linoleic, and linolenic) was greater in treatments WF, SG, and LO, respectively, while the values of conjugated linoleic acid (CLA) were greater when animals were fed LO. The inclusion of LO in the diet enhances the concentration of CLA in longissimus muscle and subcutaneous fat besides improving the atherogenicity index and elongase activity. As such, LO can be used with the aim to improve the quality of beef from confined Nellore cattle. Conversely, the use of PO is not recommended since it may increase the concentration of undesirable unsaturated fatty acids in muscle and subcutaneous fat, shear-force and the atherogenicity index.

  • We conducted an 8-week feeding trial to evaluate dietary lipid sources on the growth performance and body composition of juvenile river puffer fish Takifugu obscurus. Nine experimental diets were formulated with fishmeal as the major protein ingredients, providing 50% crude protein. The experimental diets contained either beef fallow (BF), soybean oil (SO), rapeseed oil (RO), or linseed oil (LO). Each of these diets was then supplemented or not with 0.5% n-3 HUFA (BFH, SOH, ROH, and LOH), resulting in a total of eight experimental diets. The control diet contained fish oil (FO) as the lipid source. Fish averaging $10.3{\pm}0.03g$ were fed the experimental diets in randomly selected triplicate groups for 8 weeks. Weight gain and feeding efficiency of fish fed the FO and SOH diets were significantly higher than those of fish fed BF or RO (P<0.05), but these diets did not differ significantly from the other diets. The protein efficiency ratio of fish fed the SOH diet was significantly higher than that of fish fed the BF, SO, or RO diets (P<0.05), but these were not significantly different from the other diets. The specific growth rate of fish fed the FO and SOH diets was significantly higher than that of fish fed the BF diet (P<0.05). Whole body DHA and n-3 HUFA contents of fish fed the FO diet were significantly higher than those of fish fed the SO, RO, or LO diets (P<0.05), but were not significantly different from the other diets. These results indicate that soybean oil and linseed oil could replace up to 100% of fish oil in the diet containing 60% fishmeal for river puffer fish.

  • This study was conducted to investigate the effects of dietary lipid sources on survival, growth anc body composition of snail (Semisu1cospira gottschei). Three replicate groups of snail (average weighing 152mg) were fed the diets containing different lipid sources such as lauric acid (LA), squid liver oil (SO), linseed oil (LO), corn oil (CO), SO+ LO, SO+CO, LO+CO and SO+LO+CO for 8 weeks. Survival was not affected by dietary lipid sources (p>0.05). Weight gain of snail fed the SO, SO+LO and SO+LO+CO diets was significantly higher than that of snail fed the LA and LO diets (P<0.05), and the lowest weight gain was observed in snail fed the LA diet (P<0.05). No significant difference was found in crude lipid content of edible portion in snail fed the different diets (P>0.005). Contents of 12:0, 18:2n­6, 18:3n-3 and 20:5n-3 from snail fed the LA, CO, LO and SO diets were higher than those from snail fed the other diets, respectively (p<0.05). The highest 22:6n-3 content was observed in snail fed the SO+ LO but was not significantly different from that of snail fed the SO, SO+CO and SO+LO+CO diets (p>0.05). The n-6 highly unsaturated fatty acids such as 20:4n-6 and 22:4n-6 contents of snail were not affected by dietary lipid sources (p>0.05). These results suggested that squid liver oil and mixture of squid liver oil and linseed and/or corn oil are good dietary lipid sources for the normal growth of snail. However lauric acid may not be a good lipid source for snail diet.

  • This work was undertaken to study the effect of dietary fat source on the fatty acid profile of pork, and to evaluate the effect of inclusion of vitamin E in pig diets on lipid oxidation of pork tissue and processed pork products. Fifty-six pigs were allocated to four treatments, that included two dietary fat sources and two levels of vitamin E inclusion. Dietary fat was derived from either tallow, a source of saturated fatty acids (SFA), or from a mixture of soybean and linseed oils, which contain polyunsaturated fatty acids (PUFA). Vitamin E was included at either 0% or 0.011% of the diet. Growth and carcass characteristics were not affected by the dietary treatments. Dietary fat source affected the fatty acid profile of the longissimus muscle and subcutaneous fat tissue, with the PUFA diet resulting in significantly more polyunsaturated fatty acids in the tissues, and more favourable ratios of SFA to PUFA and C18:2 to C18:3 in terms of human health considerations. Lipid oxidation was significantly greater in tissues and processed products from PUFA-fed pigs. Inclusion of vitamin E in the diets, however, reduced the extent of lipid oxidation in the meat and meat products. Dietary manipulation of the fatty acid profile of pigs is an effective means of altering the fat composition of pork in order to provide human consumers with a healthy product. Vitamin E is effective as an antioxidant agent, particularly where processed products are concerned.

  • 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.

  • This study was conducted to examine the effect of dietary n-3/n-6 fatty acid (FA) ratio on in vitro dry matter digestibility (IVDMD), fermentation indices and FA profile. Rice bran was mixed with oil sources (cotton seed oil and linseed oil) to make the diets at 0.02, 0.29 and 0.61 of dietary n-3/n-6 FA ratio. These diets (0.5g) were placed into the incubation bottles with 40 ml of anaerobic culture medium, which contained rumen fluid and Van Soest medium at 1:2 ratio. Five replicates of each diet and two blanks were incubated at $39^{\circ}C$ for 48 hours. After incubation, the incubated contents were centrifuged. The residues were freeze-dried for DMD and FA analyses. The supernatant was used for pH, $NH_3-N$ and volatile fatty acid analyses. The concentrations of lactate (p<0.001) and iso-valerate (p<0.001) decreased linearly with increasing dietary n-3/n-6 FA ratio, but acetate concentration (p=0.056) and the ratio of acetate to propionate (p=0.005) was increased linearly. The concentrations of n-3, n-6 FA and the ratio of n-3/n-6 FA in residues increased (p<0.001) linearly with increasing dietary n-3/n-6 FA ratio, but C18:1n-9 FA concentration was decreased (p<0.001) linearly. With these results, it could affect fermentation characteristics and FA profile of rumen content by dietary n-3/n-6 FA ratio.

  • The modern unique woodworking furniture has been made in earnest from 50 years ago. Some oil from nut such as soybean, walnut and perilla, which is usually used in our common life, has been used as finishing material for the unique woodworking furniture. Recently, woodworking studio business among the whole furniture industry has grown gradually and many woodworkers uses various kinds of imported wood finishing oil. Many woodworkers use the imported finishing oil in the old ways instead of understanding the characters of the various kind of oil and It causes some serious problems in furniture finishing process. Therefore, this study aims at taking theoretical approach in wood finishing oil and presenting correct usage in understanding the types and characters of oil. Resultingly the new method of oil finishing for wood is suggested and this suggestion is to guide woodworkers into the right usage of wood finishing oil.

  • Four Holstein cows were used in a 4 ${\times}$ 4 Latin square experiment to study effects of fat sources on rumen metabolism and digestibility of nutrients. All cows were fed a total mixed diets containing 60% silage and 40% concentrate. The four concentrates were formulated to contain either Megalac(MEG), formaldehyde-treated whole linseed(LIN), a mixture (50 : 50, oil basis) of fish oil and formaldehyde-treated whole linseed(MIX), or no fat source in the concentrate but 500g per day of linseed oil being infused into the duodemm (OIL). The rumen pH was lowest in OIL among the treatments(P < 0.05), but ammonia N concentration in the rumen was not significantly different among the treatments. The differences of total VFA, acetate, propionate, iso-butyrate and iso-valerate concentrations were not significant among the treatments. While, butyrate and valerate were highest in OIL and lowest in MEG(P < 0.05 and P <0.01, respectively). In addition, A:P ratio was also highest in OIL and lowest in MEG(P < 0.05). As expected, intake of nutrients(DM, OM, NDF and ADF) was lowest in OIL among the treatments(P < 0.01). However, all nutrients flow to the duodenum, and digestion in the rumen and total tract were not significantly different among the treatments. Intake of N was highest in MEG, but lowest in OIL treatment(P < 0.01). Duodenal flow of total N, nonammonia N and microbial N was not significantly different across the treatments. In addition, microbial synthesis and ammonia N and total N digestibility were not affected by different dietary fat sources. The present results show that fermentative characteristic and microbial efficiency in the rumen, and nutrients digestibility in the rumen and total tract were not depressed by supplementation of as much as 6% dietary fat sources.

  • The black cutworm, Agrotis ipsilon (Hufnagel), damages various cultivated crops and it can also be a serious pest of turfgrass, especially on golf courses. Essential oils have potential as alternative control agents for insect pests. Sixteen essential oils (anise, camphor, cinnamon, citronella, clove, fennel, geranium, lavender, lemongrass, linseed, neem, peppermint, pine, thyme, turpentine and tea saponin) and paraffin oil were assessed in the laboratory, the green house and field trials for their efficacy against black cutworms in turf. Treatment of potted cores of perennial ryegrass turf with anise, cinnamon, neem, paraffin or turpentine reduced black cutworm damage in a greenhouse trial, and in a similar trial, applying neem oil at 4000, 2000 and 1000 ppm resulted in 100, 100 and 64% mortality, respectively, of black cutworms. Weight of survivors at the 1000 ppm rate was 5- fold less than weight of comparably-aged controls. Neem oil (2000 ppm) reduced growth of black cutworms feeding on treated clippings. A high rate of neem oil followed by irrigation (0.1 L of 20000 ppm neem oil with 0.9 L watering/$m^2$) was more effective than a lower concentration (1 L of 2000 ppm neem oil/$m^2$) against $2^{nd}$ and $3^{rd}$ instars in potted turf cores and field plots, respectively. However, not even the aforementioned higher rate effectively controlled $4^{th}$ instars in the field.
