Abstract The study objective was to assess the contribution of fat source and vitamin E (VE) supplementation on growth performance, antioxidant status, and fatty acid profile in the liver of pigs at heavy slaughter weight (148.09 ±1.64 kg). A total of 72 individually-fed pigs (36 barrows, 36 gilts; 28.55 ±1.16 kg) were randomly assigned to 12 dietary treatments in a 2 × 6 factorial arrangement. Fat treatments were tallow and corn-oil. The VE treatments included four levels of α-tocopheryl-acetate (ATA; 11, 40, 100, and 200 ppm) and two levels of mixed tocopherols (primarily γ-tocopherol; 40 and 100 ppm). Liver samples were collected at slaughter. Data analysis were performed by ANOVA using GLM in SAS. No effect of dietary fat sources, isoforms of VE, and levels of γ-tocopherol were detected on growth performance or liver antioxidant status (GSH, GSSG, SOD, and MDA). Increasing dietary ATA linearly increased overall ADG (0.98, 1.02, 1.02, and 1.08 kg/day; P = 0.02) from 28 to 150 kg; overall ADG of pigs fed γ-tocopherol-diets was 1.07 and 1.04 kg/day, respectively. An interaction between fat sources and ATA was observed on cumulative ADG during Phase1-3 (28-100 kg; P = 0.04) and Phase1-4 (28-125 kg; P = 0.03) wherein pigs fed corn-oil-diet, but not tallow-diet, had increased ADG with increased dietary ATA. Increasing dietary ATA quadratically increased SOD activity (P < 0.05; highest at 100 ppm), and quadratically decreased MDA content (P < 0.05; lowest at 40 ppm) in the liver. Liver fatty acid profile was affected by fat source (P < 0.05) but not VE treatment, pigs fed corn-oil-diets had less SFA (34.23 vs. 35.45%; P = 0.02) and MUFA (11.98 vs. 18.38%; P < 0.0001), but more PUFA (49.14 vs. 40.78%; P < 0.0001) than pigs fed tallow-diets in the liver. Beneficial effects of dietary VE supplementation were observed on growth performance and antioxidant status of pigs under conditions of this study.

We examined the influence of a diet containing 4% of rapeseed oil, 35 mg or 126 mg copper and supplement of 100 mg vitamin E per 1 kg on fatty acid profile and cholesterol content in raw and cooked broiler leg meat. Copper was added to feed mixtures as CuSO<sub>4</sub>.5H<sub>2</sub>O. The fatty acid profile and cholesterol content were also determined in raw, stewed and roasted meat of broilers receiving the same diet but with a supplement of 20 mg vitamin E. The results showed that 126 and 35 mg Cu/kg significantly increased oleic acid content. Monounsaturated fatty acids accounted for 51% and 52% of all fatty acids. The relatively low copper concentration of 35 mg/kg feed with a major portion of soybean, wheat and maize and vitamin E supplementation of 100 mg/kg reduced (P &lt; 0.01) EPA by 17%, DPA by 16% and DHA by 11 and 15% (P &lt; 0.05). All tested copper doses reduced cholesterol: 126 mg Cu by 22%, 35 mg by 6% and 126 mg in combination with 35 mg copper in relation to broiler age by 7% (P &lt; 0.05); none of the cooking procedures influenced cholesterol. Meat cooking in experiment 1 did not influence the content of any fatty acid. Copper &times; cooking interactions were insignificant for all fatty acids and cholesterol. In experiment 2 more changes in the numerical values of fatty acids were caused by stewing compared to roasting. Among the valuable fatty acids n-3 long chain acids were influenced by both cooking procedures to the largest extent. Docosahexaenoic acid was reduced to about 60% of the original value (P &lt; 0.05). On the other hand, a decrease in myristic acid by 14% in stewed meat and 12% in roasted meat (P &lt; 0.05) was positive.

Acid Accumulation

A high-carbohydrate diet (HCD) is a well-established experimental model of accelerated liver fatty acid (FA) deposition and inflammation. In this study, we evaluated whether canola oil can prevent these physiopathological changes. We evaluated hepatic FA accumulation and inflammation in mice fed with a HCD (72.1% carbohydrates) and either canola oil (C group) or soybean oil (S group) as a lipid source for 0, 7, 14, 28, or 56 days. Liver FA compositions were analyzed by gas chromatography. The mRNA expression of acetyl-CoA carboxylase 1 (ACC1) was measured as an indicator of lipogenesis. The mRNA expression of F4/80, tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, and IL-10, as mediators of liver inflammation, were also measured. The C group stored less n-6 polyunsaturated FAs (n-6 PUFAs) and had more intense lipid deposition of monounsaturated FAs (MUFAs), n-3 PUFAs, and total FAs. The C group also showed higher ACC1 expression. Moreover, on day 56, the C group showed higher expressions of the inflammatory genes F4/80, TNF-α, IL-1β, and IL-6, as well as the anti-inflammatory IL-10. In conclusion, a diet containing canola oil as a lipid source does not prevent the fatty acid accumulation and inflammation induced by a HCD.

Effect of Pasture or Maize Silage Feeding on the Nutritional Value of BeefThe objective of this study was to evaluate the nutritional value of beef from different production systems. The study was conducted with Hereford bulls on organic and conventional farms. On the organic farm, fattening was mainly based on roughages, including pasture forage in the summer season, when the end of fattening occurred. On the conventional farm the bulls were fed maize silage and concentrate. On both farms, the animals were aged 7-9 months at the beginning of fattening. The bulls were fattened to a final body weight of 550-600 kg. Samples of longissimus thoracis muscle were collected from half-carcasses of slaughtered bulls originating from each farm to analyse fat content, fatty acid profile, and content of selected minerals and vitamin E. Muscle samples were additionally analysed for the concentration of thiobarbituric acid-reactive substances 3 and 7 days after slaughter. Analyses showed a lower fat content in longissimus thoracis muscle of bulls from the pasture feeding system. The fatty acid profile was also characterized by a lower content of C 14:0, and a higher content of polyunsaturated fatty acids (PUFA), including C18:3 n-3, conjugated linoleic acid, C 20:5 n-3, and C 22:5 n-3, as well as by a lower ratio of n-6/n-3 PUFA. The total content of monounsaturated fatty acids was significantly higher in animals fed maize silage and feed concentrate. In turn, the muscle of pasture fed animals had higher levels of Na, Zn and Fe as well as of vitamin E.

This study aimed to evaluate the effects of supplementation with sunflower seeds and vitamin E for fattening lambs, on the chemical composition, cholesterol, vitamin E level, fatty acid profile and lipid oxidation of meat from sheep. Four treatments were evaluated, as follows: SC – basal diet consisting of sugarcane + concentrate; SCS – basal diet supplemented with sunflower seed; SCE – basal diet supplemented with 1000 mg vitamin E; SCSE – basal diet supplemented with sunflower seed and 1000 mg vitamin E. The Longissimus lumborum muscle of 32 Ile de France lambs, which were slaughtered when their bodyweight reached 32 kg, was used. The chemical composition of the lamb meat was not significantly different (P > 0.05) between the treatments. Sunflower seed supplementation increased (P < 0.05) the levels of linoleic acid, vaccenic acid and conjugated linoleic acid. Inclusion of vitamin E in the diet increased (P < 0.05) the concentration of vitamin E in the meat while decreasing lipid oxidation. Considering the current demand for healthy foods, inclusion of sunflower seeds and vitamin E in the diet of sheep is a viable possibility.

Four Alpine does were used in a 4 × 4 Latin square design to determine the effects of feeding canola oil at four levels: 0, 2, 4 and 6% on milk fatty acid profile. The sum of C12:0 + C14:0 + C16:0 (hypercholesterolemic fatty acids) decreased linearly and C18:0 + C18:1: C16:0 (indicator of cholesterolemic tendency of fat source) increased linearly (P < 0.01) with increased canola oil intake.
