Twenty-four Malpura lambs (28 days old) were distributed into three equal groups (four each from either sexes). They were fed ad libitum on three experimental diets containing graded levels of calcium salt of fatty acids (source: rice bran oil; Ca-FA) at 0 (T1), 20 (T2) and 40 (T3) g per kg of concentrate and dry roughage (Prosopis cineraria leaves) up to 6 months of age along with suckling of mother till weaning (3 months). Effect of Ca-FA supplementation on liveweight gain, feed and nutrient intake was not observed during pre-weaning (28–90 days), which however increased (P < 0.05) in T3 during post-weaning (90–180 days). There was an increase in organic matter intake and digestibility as well as metabolisable energy intake in Ca-FA-supplemented groups. Rumen ammonia-N and ciliate protozoa population was increased (P < 0.05) in T2 and T3 with a positive shift in rumen fermentation (increased propionate and decreased acetate). Blood biochemical analysis revealed effect of treatment and age (P < 0.05) for free fatty acids and cholesterol concentration. Ca-FA supplementation improved (P < 0.05) dressing percentage both at 2% and 4% CA-FA inclusions levels with no change in fat yield and composition. It is concluded that supplementation of Ca-FA prepared from industrial-grade rice bran oil in growing lamb rations improved gain, organic matter intake and digestibility during the post-weaning period and a linear response to the level of supplementation recommends Ca-FA at 40 g/kg for improved lamb performance.

This research aimed to study the effect of solvents, namely n-hexane and ethanol, on the yield of crude rice bran oil extraction. The effects of extraction temperatures of 50, 60, and 70 ºC and extraction times of 1, 3, 6, 12, and 24 h were investigated. Rice bran composition was determined. It was found that protein, lipid, moisture, fiber, ash, and carbohydrate content were 12.65±0.56, 16.32±0.81, 7.65±0.62, 10.25±0.64, 6.38±0.59, and 46.75 %, respectively. From the results, the rice bran oil yield from n-hexane extraction was significantly higher than ethanol extraction, with p < 0.05. The maximum rice bran oil obtained from n-hexane extraction was 16.23±0.34 %. The highest yield of rice bran oil was obtained from extraction temperature of 60 - 70 ºC for 12 - 24 h. After extraction by the optimum conditions at 60 ºC for 12 h, the rice bran oil was kept for 1, 2, 3, 4, and 8 weeks for investigation of its quality changes. It can be concluded that the optimum conditions for rice bran oil extraction was with using n-hexane as a solvent for extraction at a temperature of 60 ºC for 12 h. Storing oil for 0, 1, 2, 4, and 8 weeks resulted in the increase of free fatty acids (FFA) and peroxide value, whereas iodine value and saponification value were relatively constant.

The objective of this study was to produce trans-free fat spread from rice bran oil and rice bran oil shortening blends to replace partially hydrogenated fats which contain high levels of trans fatty acids. The W/O emulsion of rice bran oil spread was prepared from blending of rice bran oil and rice bran oil shortening with the mass ratio of 40: 60 using PGPR as an emulsifier. Physicochemical properties, fatty acid compositions, thermal behaviors, micronutrients, sensory attributes and oxidative stability of rice bran oil spread were investigated and compared with commercial spread products. Results showed that physicochemical properties of the rice bran oil spread were similar to the commercial spread (B2). Trans fatty acids contents of the rice bran oil spread (0.2% TFAs) were much lower than the commercial spread (F2) produced from partially hydrogenated fat (4.9% TFAs). Thermal behaviors and SFC profile indicated good physical properties and spreadability of the rice bran oil spread which were comparable to the commercial spreads. Micronutrients in the rice bran oil spread were greater than those of commercial spread products. The rice bran oil spread had the highest overall preference scores compared to the two commercial fat spreads. In addition, the rice bran oil spread exhibited high oxidative stability. This study demonstrated that rice bran oil and rice bran oil shortening blends can be used as an alternative source of partially and fully hydrogenated fats as well as tropical oils to produce trans-free fat spreads with desirable properties.

This trial was performed to determine the effect of rice bran oil (RBO) inclusion in diets of broiler chickens on performance, carcass characteristics, blood parameters, meat quality, antioxidant activity, liver lipid content, and liver histological structure. The 35-day feeding trial was conducted on 240 one-day-old Ross 308 broiler chickens, allocated to four treatment groups with six replicates each. RBO was examined at different inclusion levels, 0% (control), 1% (RBO1%), 1.5% (RBO1.5%), and 2% (RBO2%) in a completely randomized design. The results showed that at the end of the trial (35 days) the RBO supplementation had positive effects (p < 0.001) on the productivity parameters, but the feed intake was linearly decreased due to RBO inclusion. In addition, RBO supplementation linearly improved (p < 0.05) the dressing percentage, breast yield, immune organs relative weights, and meat glutathione concentration, while it decreased (p < 0.01) the abdominal fat yield and meat crude fat, triglycerides, cholesterol, and Malondialdehyde (MDA) contents in broiler’s meat. Moreover, serum total protein, globulin, and high-density lipoprotein contents improved noticeably (p < 0.01) due to offering an RBO-supplemented diet, but serum total lipids, total cholesterol, triglyceride, low-density lipoprotein, and aspartate aminotransferase concentrations linearly reduced (p < 0.01). The RBO supplementation augmented (p < 0.05) the phagocytic index, phagocytic activity, and antibody titer compared to control. On the other hand, RBO inclusion had no effect on the breast, thigh, or abdominal fat color parameters. Moreover, RBO supplementation reduced (p < 0.01) the content of total saturated FA (SFA), but increased (p < 0.01) the content of total monounsaturated FA (MUFA), and polyunsaturated FA in both breast and thigh meat. Chemical analysis of the liver tissue samples revealed that the inclusion of RBO linearly reduced (p < 0.05) hepatic cholesterol, triglyceride, and MDA contents. Histologically, the lipid percentage and number of lipid droplets (p < 0.01) were markedly lessened in the RBO-supplemented groups. The histological structure of the liver asses by light and electron microscope were normal in all groups without any pathological lesions. It is concluded that RBO could be used as a valuable ingredient in broiler chickens’ diets to stimulate the growing performance and immune status, enhance the antioxidant activity and blood lipid profile, augment liver function, and improve the nutritive value of the meat.

The present study was done to evaluate the quality and the vitamin A fortification status of 5 types of commercial edible oils sold in Dhaka city markets. The percentages of free fatty acid (FFA), peroxide value (POV), iodine value (IV) and fatty acid composition were estimated to evaluate the quality and vitamin A content were determined to evaluate the vitamin A fortification status of 25 commercial edible oils- soybean oil, sunflower oil, rice bran oil, mustard oil and palm olein (5 brands of each) . The results revealed that FFA, POV and IV of the commercial oils analyzed were within the BSTI standard limits. The highest saturated fatty acids (SFA) values ranging from 39.85 ± 0.005 to 46.97 ± 0.002 % was found in palm olein samples and the lowest SFA values ranging from 4.56 ± 0.031 to 6.97 ± 0.096 % was found in mustard oils. On the other hand, mustard oils contained highest monounsaturated fatty acids (MUFA) ranging from 69.30 ± 0.189 to 75.87 ± 0.069 % compared to other oils analyzed. Highest polyunsaturated fatty acids (PUFA) were recorded in sunflower oils 64.78 ± 0.035% followed by soybean oils 63.25 ± 0.245%. In addition, except sunflower and mustard oils, vitamin A was found in all the soybean and rice bran oils analyzed. On the contrary, vitamin A was found only in 60% of the palm olein samples analyzed and the content was much lower than the standard value (15-30 ppm). Bangladesh J. Sci. Ind.
