“…Under these conditions, most works reported a reduction in the feed intake, growth rate or conversion rate (Koch et al, 2007) and an increase in physiological injures (Staprans et al, 2005;Szarek et al, 2006;Yuan et al, 2007) in animals given the diet including overheated oil. However, when dietary oils were peroxidised close to commercial practice and included at a medium level in diets (80 to 100 g/kg), peroxide value did not increase too much and no effect on rat performance was observed (Eder and Kirchgessner, 1999;Quiles et al, 2002;Totani and Ojiri, 2007). In fact, Totani and Ojiri (2007) even observed a tendency to increase feed consumption in rats fed with recovered frying oil compared to those given fresh oil.…”

Effect of oxidation state of dietary sunflower oil and dietary zinc and α -tocopheryl acetate supplementation on performance of fattening rabbits

Twelve diets were formulated using the same raw materials and including 3% of sunflower oil at 3 different oxidation levels [fresh (F), peroxidised (P; 55°C for 11 d; 83 meq O 2 /kg oil) and highly-oxidised (O; 140°C for 31 h; ρ-anisidine value of 125)], with 2 levels of α-tocopherol supplementation (0 and 100 ppm), and 2 levels of Zn supplementation (0 and 200 ppm). A trial with 900 growing rabbits was carried out in order to study the effect of the oxidation and protection level of supplemented oil on the performance of animals from weaning (28 d) to 63 d of age. Another coetaneous trial was performed to study the effect of the oxidation level of sunflower oil (F, P and O) on caecal activity around weaning, using 120 suckling rabbits randomly re-allocated into 12 litters of 10 kits (4 litters per diet) from 17 to 44 d of age. Four rabbits per litter were slaughtered at 30 and 44 d (16 rabbits/treatment and age). Full gastro-intestinal tract and caecum were weighed and pH, dry matter (DM), ammonia nitrogen (NH 3 ) and volatile fatty acids concentration (VFA) values in caecal content were measured. No effect was observed either in the mortality rate, body weight gain, feed intake or conversion rate throughout the growing period when peroxidised or oxidised oils were included in the diet, being on average 32%, 45.1 g/d, 107.6 g DM/d and 2.44, respectively. Dietary supplementation with α-tocopherol and/or Zn had no effect on the mortality rate, feed intake and performance of rabbits during the fattening period. Daily weight gain just after weaning (28 to 30 d of age) was higher for kits receiving the diet supplemented with F and O diets than those with the P diet (55, 50 and 35 g/d, respectively; P<0.05), but no further effect on performance was observed. Young rabbits fed with the P diet showed lower DM percentage in caecum at 30 d of age (-9.5%; P<0.05) than those with F or O diets. Caecum of young rabbits fed with the O diet presented lower NH 3 content at 30 d of age that those given F diet (-38%; P<0.05) and higher total VFA and acetic acid concentration (+36 and +34 %, respectively; P<0.05). Therefore, and although many questions are still open, oxidised oils could be considered as a possible energy source for rabbit nutrition.

“…The effects of oxidised oil on cholesterol and triglyceride concentrations are largely speculative. While some researchers obtained no significant effects in rats (Eder, 1999a) or birds , others reported that oxidised dietary oil reduces cholesterol and triglyceride concentrations (Eder & Kirchgessner, 1999;Eder, 1999b;Eder et al, 2003). However, Narasimhamurthy & Raina (1999) observed higher cholesterol and lower triglyceride concentrations in the plasma of rats fed heated/fried oils compared to the fresh group.…”

“…These results seem to agree with many previous reports in which higher TBARS levels were obtained in birds fed oxidised oil (Sheehy et al, 1993;1994;Engberg et al, 1996). Similar findings have also been reported in rats (Eder & Kirchgessner, 1999;Juskiewicz et al, 2000;Eder et al, 2003;Tabatabaei, 2008). However, Eder (1999a) suggested that the susceptibility of plasma lipids to lipid peroxidation was not significantly affected by feeding oxidised oil to miniature pigs.…”

“…The ingestion of oxidised oils also reduces tocopherol levels of tissues and plasma (Sheehy, 1993;Fei, 1995;Eder, 1999a;Jankowski et al, 2000) and increases the amount of thiobarbituric acid-reactive substances (TBARS), suggesting an elevation in lipid peroxidation and cellular fragility Sheehy et al, 1993;1994;Fei, 1995;Enberg et al, 1996;Eder & Kirchgessner, 1999;Juskiewicz et al, 2000). Similarly, Zdunczyk et al (2000) and Keller et al (2004) reported that oxidised dietary oils lead to a reduced antioxidant status of erythrocytes and make them more susceptible to haemolysis.…”

________________________________________________________________________________ AbstractThe present study was conducted so that the possible effects of thermally-oxidised dietary oil and vitamin E supplementation could be determined on the performance, lipid peroxidation, antioxidant defence system and some blood and meat quality traits of broilers. Broilers were fed grower diets containing fresh or oxidised oil, supplemented with and without vitamin E (200 mg/kg) from four to six weeks of age. Neither oxidised dietary oil nor vitamin E supplementation had any adverse effect on weight gain, feed consumption or feed conversion ratio. However, the broilers that received oxidised oil had lower levels of plasma cholesterol and triglyceride compared to the control. The glucose level was neither influenced by oxidised oil nor by vitamin E supplementation. The plasma malondialdehyde level increased slightly in broilers fed oxidised oil, indicating increased lipid peroxidation. Higher glutathione peroxidise (GSH-P x ) activity observed in the broilers fed oxidised oil suggests greater oxidative stress. Vitamin E supplementation partly depressed GSH-P x activity in broilers fed oxidised oil. This depression in enzyme activity might be the result of homeostatic compensation. The uric acid concentration was not affected by oxidised oil and vitamin E supplementation. Feeding oxidised oil did not cause a marked discolouration in breast meat. Vitamin E supplementation had some beneficial effects on colour measurements.

“…Hochgraf et al (Hochgraf et al 1997) demonstrated that oxidized linoleic acid, which is present in sunflower seeds, promotes a significant increase in the plasma cholesterol levels in rats. In contrast, some other studies reported reduced levels of plasma cholesterol and triglycerides in rats and pigs in response to the consumption of oxidized dietary oil (Eder and Kirchgessner 1999;Eder 1999;Eder and Stangl 2000;Eder et al 2003;Acikgoz et al 2011). In this context, our results demonstrated increased cholesterol levels with HFD, which agrees with the proposed of Hochgraf et al (Hochgraf et al 1997).…”
