The effects of dietary omega-6 (n-6) to omega-3 (n-3) polyunsaturated fatty acid (PUFA) ratios on growth performance, digestibility, blood lipid profiles, fecal microbial counts, and meat quality in finishing pigs were examined by using linseed and fish oil. A total of 140 crossbred finishing pigs [(Landrace × Yorkshire) × Duroc] were used in a 10 wk trial. Pigs were blocked based on body weight (BW) and sex and randomly allotted to four dietary treatments formulated to have n-6/n-3 ratios of 5/1, 10/1, 15/1, and 17/1 (control). Throughout the experiment, BW, average daily gain, and average daily feed intake were significantly (P < 0.05) increased with a decreased ratio of n-6/n-3 PUFA. Energy digestibility and fecal Lactobacillus count showed a linear (P < 0.05) increase in week 10. The high-density lipoprotein cholesterol and blood triglyceride concentrations increased (P < 0.1) during week 10. However, low-density lipoprotein cholesterol was reduced (P < 0.05) linearly during week 5 and week 10 with a reduction in dietary n-6/n-3 ratio. This study provides a basis for future research on altering n-6/n-3 ratio by using linseed oil and refined fish oil in finishing pigs.

Abstract A total of 72 crossbred pigs [(Landrace × Yorkshire) × Duroc] with an average initial BW of 51.59±1.59 kg were used in this 10-wk feeding trial to investigate the effects of different dietary n-6:n-3 polyunsaturated fatty acids (PUFA) ratios in finishing pigs. Pigs were randomly allotted to 3 dietary treatments (each n=24) with 6 replications and 4 pigs per pen (2 barrows and 2 gilts). Pigs were fed a corn-soybean meal-based diets formulated by replacing soybean oil with linseed oil to achieve n-6:n-3 close to 5:1, 10:1 and 15:1, respectively. The growth performance, carcass traits and meat quality parameters (meat color, sensory evaluation, cooking loss, drip loss, pH, longissimus muscle area and water holding capacity) were not influenced (P>0.10) by various dietary n-6:n-3 ratios. Pigs fed dietary n-6:n-3 PUFA ratios of 5:1 had a lower (P<0.05) serum total cholesterol, LDL cholesterol and triglyceride levels. The concentrations of n-3 PUFA , including C18:3n-3, C22:5n-3 and C22:6n-3 were improved (P<0.05) in the longissimus dorsi muscles of pigs fed dietary n-6:n-3 PUFA ratios of 5:1. Furthermore, pigs fed dietary n-6:n-3 PUFA ratio of 5:1 decreased (P<0.05) the n-6 concentrations (C18:2n-6 and C20:4n-6) of longissimus dorsi muscles. In conclusion, lowering the dietary n-6:n-3 ratios to 5:1 could be beneficial for the blood lipid profiles, and improve the nutritional value of pork, without adverse effect on growth performance and meat quality parameters that are related to the consumer acceptance.

This study was conducted to evaluate the effects of herb mixture (summer shield) supplementation on growth performance, nutrient utilisation, and plasma lipid profiles in broiler chickens. Thirty-six male chicks at 15&nbsp;days of age were divided into three groups with three replicates of four birds. The control group of chicks was fed a basal diet and the remaining two groups of chicks were fed the basal diet supplemented with summer shield at a concentration of 1 g/kg or 2 g/kg, respectively, until 37 days of age. Although feed intake was not different among the three groups, both body weight gain and breast muscle weight were increased in chicks fed a summer shield-supplemented diet. Summer shield supplementation decreased abdominal fat weight and consequently feed efficiency was improved. Both protein and fat utilisation was improved in chickens fed a summer shield-supplemented diet although dry matter content was not influenced. In addition, summer shield supplementation improved plasma lipid profiles, i.e., total cholesterol, triglyceride, and low-density lipoprotein cholesterol were decreased, whereas high-density lipoprotein cholesterol was increased. Furthermore, summer shield supplementation increased total protein, albumin, and globulin levels in plasma, while neither glutamate oxaloacetate transaminase nor glutamate pyruvate transaminase were affected. These results suggest that summer shield supplementation has positive effects on growth performance, nutrient utilisation, and plasma lipid profiles in broiler chickens.

This study was conducted to evaluate feeding periods of dietary conjugated linoleic acid (CLA) supplementation on growth performance, nutrient digestibility, blood profiles, and meat quality in finishing pigs. A total of 150 finishing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 83.13 ± 1.91 kg were randomly allocated into one of three treatments (10 pens per treatment, five pigs per pen) based on their BW. Dietary treatments consisted of supplementing the basal diet with 1.0% CLA during 2, 3, and 4 wk prior to finishing. Pigs fed CLA diets 2 wk before finishing had a higher overall average daily gain (ADG) and gain-to-feed ratio (G/F) than those fed CLA diets 4 wk before finishing (P < 0.05). In the whole experiment, pigs fed CLA diets 2 wk before finishing had a higher serum low-density lipoprotein (LDL) than those fed CLA diets 3 and 4 wk before finishing. However, pigs that received CLA diets 4 wk before finishing had higher triglyceride levels (P < 0.05). Feeding 1% CLA diets 4 wk before finishing improved meat color and firmness. Taken together, feeding 1% CLA diet 4 wk before finishing increased ADG, G/F, and serum LDL, but reduced serum triglyceride.

Inulin is one of the commercially feasible dietary fibers that has been implicated in regulating the gut health and metabolism of animals. This experiment was conducted to investigate the effect of dietary inulin supplementation on growth performance and meat quality in growing–finishing pigs. Thirty-six Duroc × Landrace × Yorkshire White growing barrows (22.0 ± 1.0 kg) were randomly allocated to two dietary treatments consisting of a basal control diet (CON) or basal diet supplemented with 0.5% inulin (INU). Results showed that inulin supplementation tended to increase the average daily gain (ADG) at the fattening stage (0.05 < p < 0.10). Inulin significantly increased the dressing percentage (p < 0.05) and tended to increase the loin-eye area. The serum concentrations of insulin and IGF-I were significantly higher (p < 0.05) in the INU group than in the CON group. Moreover, inulin supplementation significantly elevated the expression level of myosin heavy chain II b (MyHC IIb) in the longissimus dorsi (p < 0.05). Inulin significantly upregulated the expression of mammalian rapamycin target protein (mTOR) but decreased (p < 0.05) the expression level of muscle-specific ubiquitin ligase MuRF-1. These results show the beneficial effect of inulin supplementation on the growth performance and carcass traits in growing–finishing pigs, and will also facilitate the application of inulin in swine production.

This study was conducted to evaluate the effect of choline chloride alone and in combination with propylene glycol on the growth performance, meat quality and backfat in finishing pigs. A total of 90 crossbred ((Landrace× Yorkshire)× Duroc) pigs with an average initial body weight (BW) of 75.15± 1.94 kg were randomly distributed by BW and sex. This 8-week experiment consisted of 3 dietary treatments with 6 replications per treatment and 5 pigs per pen. The experiment included 3 treatments: CON, basic diet; TRT1, basic diet+0.05% choline chloride; TRT2, basic diet+0.05% biocholine P (chloride chloride and propylene glycol). Body weight was statistically higher (P less than 0.05) in pigs fed TRT2 diet than the CON diet in week 8. During 4 to 8 weeks and overall, the average daily gain (ADG) was significant higher (P less than 0.05) in the pigs fed TRT2 diet than the CON diet. Digestibility of nitrogen was significantly increased (P less than 0.05) at week 4 and week 8, back fat was higher (P less than 0.05) in week 6 and week 8 in pigs fed TRT2 diet than the CON diet. In conclusion, dietary TRT2 can increase the BW, ADG, nitrogen, and backfat in finishing pigs.

Age-related memory loss shares similar risk factors as cardiometabolic diseases including elevated serum triglycerides (TGs) and low-density lipoprotein cholesterol (LDL-C) and reduced high-density lipoprotein cholesterol (HDL-C). The mechanisms linking these aberrant blood lipids to memory loss are not completely understood but may be partially mediated by reduced integrity of the hippocampus (HC), the primary brain structure for encoding and recalling memories. In this study, we tested the hypothesis that blood lipid markers are independently associated with memory performance and HC viscoelasticity—a noninvasive measure of brain tissue microstructural integrity assessed by high-resolution magnetic resonance elastography (MRE). Twenty-six individuals across the adult lifespan were recruited (14 M/12 F; mean age: 42 ± 15 y; age range: 22–78 y) and serum lipid profiles were related to episodic memory and HC viscoelasticity. All subjects were generally healthy without clinically abnormal blood lipids or memory loss. Episodic memory was negatively associated with the TG/HDL-C ratio. HC viscoelasticity was negatively associated with serum TGs and the TG/HDL-C ratio, independent of age and in the absence of associations with HC volume. These data, although cross-sectional, suggest that subtle differences in blood lipid profiles in healthy adults may contribute to a reduction in memory function and HC tissue integrity.

Background: Aromatase inhibitors (AIs) influence blood lipid profiles. However, relatively few studies have directly compared the treatment effects of steroidal and nonsteroidal AIs. Methods: A prospective single-center cohort study was conducted to investigate the effects of steroidal and nonsteroidal AIs on lipid profiles during the first 24 months of endocrine therapy in hormone receptor-positive postmenopausal patients with early breast cancer. The primary endpoint was the cumulative incidence of lipid events, while the secondary endpoints were changes in lipid profiles and lipid event-free survival. Results: Comparison of the lipid profiles of the two groups showed that triglycerides (TGs) and total cholesterol (TC) levels were significantly higher in the nonsteroidal AI group over 24 months ( p < 0.05), whereas low-density lipoprotein cholesterol (LDL-C) was significantly higher only at 3 months ( p = 0.017) and 6 months ( p = 0.026). High-density lipoprotein cholesterol (HDL-C) was significantly lower in the steroidal group at all time points ( p < 0.05), except at 18 months ( p = 0.085). The cumulative incidence of lipid events in the steroidal and nonsteroidal groups at 24 months was 25.3% and 37.0%, respectively. Multivariate analysis results indicated that TG, LDL-C, and steroidal AIs were independently associated with blood lipid events. Conclusion: This trial showed that a significantly higher cumulative incidence of lipid events occurred in the nonsteroidal AI group than in the steroidal AI group, which indicated that steroidal AIs exerted a protective effect against blood lipid events in postmenopausal women receiving an AI as adjuvant therapy for breast cancer.
