Oxidized Oil

Abstract High environmental temperature due to climate change can accelerate oxidation of feed during storage and preparation. Oxidized feed can cause elevated oxidative stress in live birds, resulting in decreased productivity and meat quality of broilers. The study was aimed to determine effects of feed containing oxidized oil on growth performance, plasma oxidative stress, and breast meat quality of broilers. Male broilers (192; Cobb500) at 21 days old were randomly allotted to 32 pens (8 pens/treatment) and raised for 21 days. The birds were fed feed containing fresh (Control) or oxidized corn oil (5%, Peroxide Value:140) with or without vitamin E (500 IU/kg feed) supplementation. Growth performance, oxidative stress markers in plasma collected at Day 42, and quality parameters of breast meat harvested at Day 43 were determined. Data were analyzed using proc glm and means were compared using Tukey’s studentized range (HSD) test. Oxidized feed and/or vitamin E supplementation did not affect growth performance and plasma DNA and protein oxidation. Oxidized feed significantly increased lipid oxidation and reduced total antioxidant capacity in plasma (P < 0.05) and, interestingly, dietary vitamin E made them worse (P < 0.05), indicating that oxidized lipids in feed can induce oxidative stress in live birds and vitamin E may act as a pro-oxidant in highly oxidized conditions. Although they did not affect sensory and functional properties of chicken breast meat, oxidized feed significantly increased lipid oxidation in cooked meat (P < 0.05) but dietary vitamin E considerably inhibited its development (P < 0.05), indicating that oxidized oil and vitamin E in feed can be accumulated in muscle and act as a pro- and anti-oxidants in meat, respectively. The results suggested that oxidized oil in feed can increase oxidative stress in live birds and susceptibility of breast meat to lipid oxidation, and dietary vitamin E can improve its oxidative stability.

Abstract Oxidative stress seriously affects poultry production. Nutritional manipulations have been effectively used to alleviate the negative effects caused by oxidative stress. This study investigated the attenuating effects and potential mechanisms of dietary taurine on growth performance and meat quality of broiler chickens challenged with hydrogen peroxide (H2O2). Briefly, a total of 192 male Arbor Acres broilers (28-day-old) were randomly categorized into 3 groups: non-injection of birds on basal diets (control), 10.0% H2O2-injection of birds on basal diets (H2O2), and 10.0% H2O2-injection of birds on basal diets supplemented with 5 g/kg taurine (H2O2+taurine). Each group consisted of 8 cages of 8 birds each. Results indicated that H2O2 administration significantly reduced growth performance and impaired breast meat quality by decreasing ultimate pH and increasing shear force value (P < 0.05). Dietary taurine improved the body weight gain and feed intake, and decreased feed/gain ratio of H2O2-challenged broilers. Meanwhile, oxidative stress induced by intraperitoneal injection of H2O2 suppressed the nuclear factor-κB (NF-κB) signaling and initiated autophagy and apoptosis. Compared with the H2O2 group, taurine supplementation restored the redox status in breast muscle by decreasing levels of reactive oxygen species and contents of oxidative products and increasing antioxidant capacity (P < 0.05). Moreover, upregulated mRNA expression of NF-κB signaling-related genes including p50 and Bcl-2, as well as enhanced protein expression of NF-κB were observed in the H2O2+taurine group (P < 0.05). Additionally, dietary taurine decreased expression of caspase family, beclin-1 and LC3-II (P < 0.05), thereby rescuing autophagy and apoptosis in breast muscle induced by H2O2. Collectively, dietary supplementation with taurine effectively improves growth performance and breast meat quality of broilers challenged with H2O2, possibly by protecting against oxidative injury and modulating cell death signaling.

Effect of partial substitution of crushed soybean by different portions of rape seed on yield and chicken breast quality (nutritive and technological) was investigated in the paper. ROSS 308 hybrids were used for investigations. Control group (K) was fed with standard mixture and experimental groups with mixture in which crushed soybean partially substituted by 10% (O1), 15% (O2) and 20% (O3) extruded rape seed (EZUR). Rape seed was extruded with corn germ in ratio 50:50. It was concluded that there are no significant differences in breast meat yield between control and experimental groups (P > 0.05). The changes in chicken meal had no influence (P > 0.05) on nutritive quality of breast meat (the contents on protein, connective tissue protein, free fat and total ash). Additionally was found that the technological quality of breast meat of the control and experimental groups averagely corresponds to "normal" meat quality considering the parameters and criteria for quality determination (pHu, L*, water holding capacity).

The aim of this paper was to investigate the carcass and breast meat (nutritional, technological and sensory) quality of chickens (line ROSS 308) fed extruded corn. It was concluded that a diet with extruded corn increases chilled carcass weight and the share of breast meat in chilled carcass. Also, the breast meat of experimental group contains more protein and less free fat comparing to the control group. Based on the parameters and criteria for defining the quality of chicken breast meat (pHu and L

We evaluated the effect of freezing (−18°C) for 12 months on the qualitative characteristics of breast, thigh and drumstick meat. Samples from male Cobb 500 broilers raised in antibiotic-free (n = 125), conventional (n = 125) and organic (n = 125) rearing systems and samples from male Hubbard ISA broilers raised in a free-range (n = 125) rearing system were used. Among the studied systems, up to the ninth month of freezing, the organic chicken breast meat showed lower (P < 0.001) water activity (aw) (0.966, on average). After 12 months of freezing, samples of antibiotic-free and organic poultry showed a pH value similar to that of fresh meat (5.94 and 5.86, respectively). Freezing for 12 months preserved the redness of drumstick meat from conventional broilers (a* = 4.86, on average) and the rearing system did not influence the aw of drumstick meat during the entire experimental period. Freezing preserved the aw of conventional and organic chicken meat samples until the ninth month of evaluation (0.978 and 0.974, respectively). Lipid oxidation in the breast, thigh and drumstick samples from the four rearing systems increased (P < 0.001) from the third month of freezing onwards. There were variations in colour, pH, aw and lipid oxidation of chicken meat among birds raised in different rearing systems. Freezing chicken meat did not prevent colour and pH changes or occurrence of lipid oxidation and did not promote a reduction of aw to levels unfavourable to microbiological development.

This study aimed at examining the effects of curcumin supplementation on growth performance, antioxidant capacity, and meat quality of ducks. To investigate these effects, 600 healthy ducks were randomly assigned to four treatment groups with 10 replicates pens, and each pen contained 15 ducks. Ducks were fed a diet containing curcumin at levels of 0, 300, 400, and 500 mg kg−1 in different groups. The results demonstrated that curcumin supplementation is beneficial to the growth performance (p < 0.05) of ducks and antioxidant capacity (p < 0.05) of duck meat. In addition, dietary curcumin raised the meat quality of ducks, improving the meat color, increasing water-holding capacity, and inhibiting lipid and protein oxidation. In conclusion, the present study provides important insights into both the nutrient and qualities of ducks, finding that a dietary inclusion of 400–500 mg/kg of curcumin (kg−1) has the greatest effect.
