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 > 0.05) the performance, nutrient digestibility and milk nutrient composition of sows. The concentrations of high-density lipid cholesterol (HDL-C) increased (P < 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 < 0.05) at Week 3 and overall respectively. The BW of piglets raised from sows fed all treatment diets were heavier (P < 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.

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.

The beneficial effect of omega-3 polyunsaturated fatty acids (PUFA) supplementation on the cardiovascular (CV) system is well supported in CV patients; however, the effect of the consumption of omega-3 PUFA-enriched functional food in healthy individuals is still not fully elucidated. This study aimed to determine the effect of the consumption of omega-3 PUFA-enriched hen eggs on the microvascular reactivity (primary outcome), blood pressure (BP), and serum lipid profile in young healthy individuals. The control group (N = 16) ate 3 ordinary hen eggs (277 mg of omega-3 PUFAs/day), and the OMEGA-3 group (N = 20) ate 3 omega-3 PUFA-enriched eggs containing 259 mg of omega-3 PUFAs/egg daily (α-linolenic acid (ALA), 167 mg/egg; eicosapentaenoic acid (EPA), 7 mg/egg; docosahexaenoic acid (DHA), 84 mg/egg) for 3 weeks (777 mg of omega-3 PUFA/day). Postocclusive reactive hyperemia (PORH) in skin microcirculation assessed by laser Doppler flowmetry, serum lipid profile, fasting blood glucose, high-sensitivity C-reactive protein (hsCRP), and arterial BP were measured in all subjects before and after the protocol. PORH was significantly enhanced, and triglycerides, hsCRP, and BP were significantly decreased in the OMEGA-3 group compared with baseline measurements, whereas there was no significant difference in the control group after the protocol when compared with baseline. To the best of our knowledge, this is the first study to demonstrate that consumption of a mixture of omega-3 PUFA (ALA + EPA + DHA), provided via enriched hen eggs, elicits changes in the microvascular reactivity, BP, and triglyceride level in healthy subjects that are associated with CV benefits, thus suggesting that daily consumption of omega-3 PUFA-enriched eggs in healthy individuals may potentially contribute to CV risk factor attenuation and disease prevention.
