This study was conducted to evaluate the effect of different omega-6: omega-3 fatty acid (FA) ratios in a corn–soybean meal-based diet in growing pigs. A total of 140 [Duroc × (Landrace × Yorkshire)] growing pigs with an average body weight (BW) of 24.75 ± 1.43 kg were used in a 6-week trial. Pigs were allocated randomly into one of four treatments according to sex and BW (seven replications with five pigs per pen). The treatment groups consisted of 4 diets with omega-6:omega-3 FA ratios of 17:1, 15:1, 10:1, and 5:1. In the current study, the energy digestibility, BW, and average daily gain (ADG) increased (p < 0.05) in pigs provided with the 5:1 diet compared to pigs fed the 17:1 diet in the sixth week. The low-density lipoprotein (LDL) concentrations of blood were lower (p < 0.05) in pigs fed the 5:1 diet compared to the 17:1 and 15:1 diet. However, the fecal microflora and fecal gas emissions were unaffected (p > 0.05) by the different omega-6: omega-3 FA ratios in diets. In conclusion, reducing omega-6: omega-3 ratio by increasing omega-3 in diet improved BW, ADG, and gross energy digestibility, and reduced the LDL concentrations of blood in growing pigs.

This study aimed to test the effects of changing omega-6 to omega-3 fatty acid (FA) ratios in corn–soybean meal-based diet on performance, serum lipid profile and colostrum and milk nutrient contents of lactating sows as well as performance of suckling piglets. In total, 32 multiparous sows (Landrace × Yorkshire) were randomly allocated into one of four dietary treatments with eight replicates per treatment. The treatment diets were fed 7 days before farrowing until weaning. The omega-3 FA used in the experiment was from linseed oil and was coated using a spray-drying method. The dietary treatments consisted of control (CON, corn–soybean meal-based basal diet with omega-6:omega-3 FA ratios of 25:1), and basal diets (CON) containing omega-6: omega-3 FA ratios at 20:1, 15:1 and 10:1 levels. Inclusion of omega-6 and omega-3 FA at different ratios in the feed did not affect (P &gt; 0.05) the performance, nutrient digestibility and milk nutrient composition of sows. The concentrations of high-density lipid cholesterol (HDL-C) increased (P &lt; 0.05) and the low-density lipid cholesterol (LDL-C) tended to be reduced (P = 0.08) at weaning for sows fed 10:1 omega 6:omega-3 ratio diet. The bodyweights (BW) and average daily gains (ADG) of piglets born from sows fed 10:1 omega-6:omega-3 FA diet were greater (P &lt; 0.05) at Week 3 and overall respectively. The BW of piglets raised from sows fed all treatment diets were heavier (P &lt; 0.05) at Week 4 (weaning) than those in the CON. Positive correlations between dietary omega-6:omega-3 FA ratio and serum HDL-C concentrations and a negative correlations between dietary omega-6:omega-3 FA ratio and serum LDL-C concentrations for sows at weaning were observed. In addition, a positive correlation between omega-6:omega-3 FA in the diet and ADG in piglets was also observed. In conclusion, inclusion of omega-6:omega-3 FA at different ratios in different proportions did not affect sow performance, while increasing HDL-C and tending to reduce LDL-C in serum lipids. However, the piglets born to sows fed 10:1 diets benefitted, with increased BW and ADG.

Dysregulated VLDL-TAG (very-low-density lipoprotein triacylglycerol) metabolism in obesity may account for hypertriacylglycerolaemia and increased cardiovascular disease. ω-3 FAEEs (omega-3 fatty acid ethyl esters) decrease plasma TAG and VLDL concentrations, but the mechanisms are not fully understood. In the present study, we carried out a 6-week randomized, placebo-controlled study to examine the effect of high-dose ω-3 FAEE supplementation (3.2 g/day) on the metabolism of VLDL-TAG in obese men using intravenous administration of d5-glycerol. We also explored the relationship of VLDL-TAG kinetics with the metabolism of VLDL-apo (apolipoprotein) B-100 and HDL (high-density lipoprotein)-apoA-I. VLDL-TAG isotopic enrichment was measured using gas chromatography-mass spectrometry. Kinetic parameters were derived using a multicompartmental model. Compared with placebo, ω-3 FAEE supplementation significantly lowered plasma concentrations of total (−14%, P<0.05) and VLDL-TAG (−32%, P<0.05), as well as hepatic secretion of VLDL-TAG (−32%, P<0.03). The FCR (fractional catabolic rate) of VLDL-TAG was not altered by ω-3 FAEEs. There was a significant association between the change in secretion rates of VLDL-TAG and VLDL-apoB-100 (r=0.706, P<0.05). However, the change in VLDL-TAG secretion rate was not associated with change in HDL-apoA-I FCR (r=0.139, P>0.05). Our results suggest that the TAG-lowering effect of ω-3 FAEEs is associated with the decreased VLDL-TAG secretion rate and hence lower plasma VLDL-TAG concentration in obesity. The changes in VLDL-TAG and apoB-100 kinetics are closely coupled.

Background: The one of the most common metabolic disorder that remains worldwide is Diabetes mellitus. Dietary intake of omega-3 fatty acid may confer a protective effect against diabetes, improves high density lipoprotein (HDL-C) and reduce low density lipoprotein cholesterol (LDL-C) levels. Objective: To observe the effect of supplementation of omega-3 fatty acid on HDL and LDL levels in type 2 DM. Methods: A prospective interventional study was conducted from January 2017 to December 2017. A total numbers of 52 diagnosed type 2 diabetic patients of both sexes were selected with age ranging from 40 to 50 years. Among them, 27 type 2 diabetic patients with supplementation of omega 3 fatty acid (2g/day) for 12 weeks was considered as study group. Another 25 type 2 diabetic patients without supplementation of omega 3 fatty acid were considered as control group for comparison. The study subjects were selected from Outpatient Department of Endocrinology, Dhaka Medical College Hospital, Dhaka and personal contact from Dhaka city on the basis of inclusion and exclusion criteria. The research work was carried out after obtaining ethical clearance from concerned departments, Research Review Committee and Ethical Review Committee of Dhaka medical college, Dhaka. The study parameters serum HDL was estimated by enzymatic colorimetric method in auto-analyzer and serum low density lipoprotein was calculated by using Friedwald formula in Department of Laboratory Medicine, Dhaka Medical College Hospital, Dhaka. The parameters were studied 2 times in study and control groups i.e. at the beginning of study (base line) and after 12 weeks of study period. Data were collected in pre-designed structured questionnaire from the researcher by herself. For statistical analysis, Paired Student’s ‘t’ test and Unpaired Student’s ‘t’ test were performed as applicable using SPSS for windows version 16.0. Results: In this study High density lipoprotein cholesterol that is good cholesterol increased and low density lipoprotein cholesterol was decreased in diabetic patients after supplementation with omega-3 fatty acid in comparison to that of their baseline value. Again, after 12 weeks, high density lipoprotein was higher and low density lipoprotein cholesterol was lower in diabetic patients after supplementation with omega-3 fatty acid in comparison to control group. Conclusion: After analyzing the results of the study, it can be concluded that omega-3 fatty acid can improve HDL and lowers LDL levels in diabetic patients may be helpful to minimize the complications of type-2 diabetes mellitus.
