“…Several authors reported that peroxidized oil reduced serum concentrations of vitamin E due to catabolism of the vitamin E during oxidative stress [8,9,17,37,45]. This fact agrees with the results found in the present study.…”

“…The addition of peroxidized oil in the diet for pigs causes oxidative stress [9,10], but the supplementation of dietary vitamin E [42] and polyphenols [43] could ameliorate the negative effects caused by oxidation [9,37]. In the present study, supplementation of vitamin E was not effective in improving pig performance, regardless of the peroxidation status of the soybean oil fed.…”

“…Feeding peroxidized oil to pigs negatively affects growth performance [12,36,37] and this decrease appears to be directly related to the extent of peroxidation. In the present study, growth performance was compromised to the largest extent from day 14 through day 35 (Phase 2), but effects were limited for the initial 14 days (Phase 1).…”

“…In contrast, Chang et al [17] did not observe differences in serum MDA due to lipid peroxidation in weaned piglets. Hung et al [37] conducted a meta-analysis using 23 studies conducted in swine and reported that serum MDA concentrations generally increased with the supplementation of peroxidized lipids. However, only few of those studies reported serum MDA concentrations as an outcome variable in that meta-analysis.…”

Background: This study evaluated the use of dietary vitamin E and polyphenols on growth, immune and oxidative status of weaned pigs fed peroxidized lipids. A total of 192 piglets (21 days of age and body weight of 6.62 ± 1.04 kg) were assigned within sex and weight blocks to a 2 × 3 factorial arrangement using 48 pens with 4 pigs per pen. Dietary treatments consisted of lipid peroxidation (6% edible soybean oil or 6% peroxidized soybean oil), and antioxidant supplementation (control diet containing 33 IU/kg DL-α-tocopheryl-acetate; control with 200 IU/kg additional dl-α-tocopheryl-acetate; or control with 400 mg/kg polyphenols). Pigs were fed in 2 phases for 14 and 21 days, respectively. Results: Peroxidation of oil for 12 days at 80°C with exposure to 50 L/min of air substantially increased peroxide values, anisidine value, hexanal, and 2,4-decadienal concentrations. Feeding peroxidized lipids decreased (P < 0.001) body weight (23.16 vs. 18.74 kg), daily gain (473 vs. 346 g/d), daily feed intake (658 vs. 535 g/d) and gain:feed ratio (719 vs. 647 g/kg). Lipid peroxidation decreased serum vitamin E (P < 0.001) and this decrease was larger on day 35 (1.82 vs. 0.81 mg/kg) than day 14 (1.95 vs. 1.38 mg/kg). Supplemental vitamin E, but not polyphenols, increased (P ≤ 0.002) serum vitamin E by 84% and 22% for control and peroxidized diets, respectively (interaction, P = 0.001). Serum malondialdehyde decreased (P < 0.001) with peroxidation on day 14, but not day 35 and protein carbonyl increased (P < 0.001) with peroxidation on day 35, but not day 14. Serum 8-hydroxydeoxyguanosine was not affected (P > 0.05). Total antioxidant capacity decreased with peroxidation (P < 0.001) and increased with vitamin E (P = 0.065) and polyphenols (P = 0.046) for the control oil diet only. Serum cytokine concentrations increased with feeding peroxidized lipids on day 35, but were not affected by antioxidant supplementation (P > 0.05). Conclusion: Feeding peroxidized lipids negatively impacted growth performance and antioxidant capacity of nursery pigs. Supplementation of vitamin E and polyphenols improved total antioxidant capacity, especially in pigs fed control diets, but did not restore growth performance.

“…This research did not follow the protocols established by PRISMA-P (Moher et al, 2015) as these were developed for human studies. This meta-analysis study follows a methodology of animal science studies, as detailed in several published articles in which meta-analysis was used in swine nutrition (Apple et al, 2007;Kiefer and Sanches, 2009;Sales, 2011;Andretta et al, 2012;Létourneau-Montminy et al, 2012;Remus et al, 2015;Hung et al, 2017;Metzler-Zebeli et al, 2012;Torres-Pitarch et al, 2017;Zeng et al, 2017;Torres-Pitarch et al, 2019).

After a collaborative and uninterrupted work, the UPS has continued to improve one more year as a Research University, and has gone from the position 6,611 in the world and 13 in Ecuador (Webometrics, 2013) to the position 2627 (Webometrics, 2020) worldwide, it is the 170 on the continent and 7 in Ecuador. The continuous improvement of all teams and the strategic vision have made progress in the World Ranking, allowing to go to 3984 positions in 7 years and 366 new positions compared to 2019. Within this global strategy of improvement of the UPS as a Research University, LA GRANJA, belonging to the area of Life Sciences, was the first university publication of Ecuador to be included in SCOPUS, Elsevier publishing house and indexed in the Emerging Source Citation Index of the Web of Science (WOS). This edition presents articles by authors from 5 countries and 16 Universities and Research Centers. We started this number 31 with the topic of weather monitoring, in an effort between the Sciences Department of Environmental Systems of Switzerland and Universidad de Cuenca, led by Dr. Ryan Padrón and his excellent team. In addition, researchers from Universidad de las Fuerzas Armadas, led by Teófilos Toulkeridis, analyze the problem of perceptions in the important and current topic of Climate Change.

Assessment of the quality, oxidative status and dietary energy value of lipids used in non‐ruminant animal nutrition

et al. 2021

BACKGROUND: Fats and oils represent the most concentrated source of energy available to animal nutritionists and form an expensive part of the diet. Thorough understanding of lipid quality and composition are required for efficient and precise diet formulation. Therefore, 724 samples of commercially available fats and oils were assessed for fatty acid profile, oxidation status and energetic value as per the Wiseman equation, with consideration of a correction factor K, which is based on the presence of the energy diluting compounds moisture, impurities and unsaponifiables. RESULTS: Energy diluting compounds were widespread across fat types and sources. Average MIU (moisture, insoluble impurities and unsaponifiable matter) presence in individual oils was 5.1-28.1 g kg −1 . Using the adapted Wiseman equation presented in the current paper, which reflects the energy diluting potential of MIU, the calculated energy values of fats and oils is reduced by up to 46% in extreme cases compared to those predicted by the original equation. From the chemical parameters, it is clear that there is limited correlation between individual measures of oxidation, with only weak negative correlations between 2-thiobarbituric acid (TBA) and Oxidative Stability Index (OSI) values (Spearman's ρ between −0.20 and −0.39) and a weak to moderate negative correlation between peroxide value (PV) and OSI (Spearman's ρ between −0.20 and −0.59) for certain fats and oils. A moderate to very strong positive correlation between FFA and the energy diluting compounds MIU was observed for all animal fats (Spearman's ρ between 0.40 and 1.00). CONCLUSION:The current report highlights the large variation in composition and quality seen in commercially available fats and oils and encourages ongoing analysis and assessment rather than reliance on published values. The results also indicate that the oxidation parameters when interpreted as separate values lack the power of inferring oil and fat quality.
