Download or read book Effect of Dietary Conjugated Linoleic Acid CLA on the Fatty Acid Status in Chicken and Meat Quality written by Min Du and published by . This book was released on 2001 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation includes studies on the effect of dietary CLA on the growth, fat accumulation and fatty acid status of chicken, and chicken meat quality as influenced by irradiation. Results showed that dietary CLA did not have significant effects on the growth rate and feed efficiency in chicken. And high levels of dietary CLA slightly reduced the whole body fat content. High ratio of dietary CLA can incorporate into chicken meat and egg yolk. Dietary CLA reduced the concentration of monounsaturated fatty acids. The concentration of polyunsaturated fatty acids, including arachidonic acid, linolenic acid and linolenic acid, also reduced as the dietary CLA level increased. However, when the dietary level of linolenic acid in diet was high, dietary CLA stimulated the synthesis of DHA and EPA, which might directly relate to the biological effects of CLA. High level of dietary CLA influenced the quality of meat, which was slightly harder and drier compared to the control meat. Dietary CLA significantly improved the oxidative stability of chicken meat. The reason for the improved oxidative and color stability of meat patties during storage should be due to the reduced unsaturated fatty acid content in chicken muscles, which improved lipid and color stability and reduced volatile production in both irradiated and nonirradiated meat during storage. Irradiation greatly increased the volatile production and induced a metal-like off-odor in chicken rolls, and dietary CLA had synergistic effect on this metal-like off-odor. Irradiation also increased the redness of chicken rolls. Consumers had a preference for the color of irradiated chicken rolls, while their reactions to the flavor of irradiated chicken rolls were quite negative.
Download or read book Effect of Conjugated Linoleic Acid Or Oleic Acid Addition on Fatty Acid Composition Profiles of Poultry Meat written by Dae Keun Shin and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two different studies were conducted to reduce the overall amount of omega-6 fatty acids in broiler chickens. The first experiment was performed to determine the effects of dietary conjugated linoleic acid (CLA) and omega-3 fatty acid combination on the omega-6 fatty acid accumulation in broiler chicken breast and thigh meat. Eight broilers from each treatment were processed at 4 and 6 weeks of age, respectively. Regarding the diets containing five different fat sources, broiler chickens fed CLA and fish oil diet had a lower C20:4 (arachidonic acid, AA, n-6) deposition but showed a higher n-3/n-6 ratio in breast and thigh meat than those fed a flaxseed oil diet and CLA and flaxseed oil diet (P 0.05). The C20:4 and n-3/n-6 ratio of breast and thigh samples from fish oil diet was similar to those of the conjugated linoleic acid and fish oil combination diet (P 0.05). However, the addition of CLA and fish oil to the diet resulted in a increase of polyunsaturated fatty acid (PUFA) concentration in broiler chicken breast and thigh meat when compared to that of fish oil diet (P

Download or read book Effects of Dietary CLA on Fatty Acid Composition of Egg Yolks and delta 9 delta 6 and delta 5 Desaturase Activities of Livers of Laying Hens written by Irene Karantzeni and published by . This book was released on 2000 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conjugated linoleic acid (CLA) alters the fatty acid composition of chicken eggs. It also decreases hepatic stearoyl-CoA desaturase mRNA in HepG2 cells. The fatty acid composition of egg yolks was investigated as a function of amount of dietary CLA for laying hens. In addition, the activities of [Delta]9-, [Delta]6-, and [Delta]5- desaturases in hen liver were investigated as a function of CLA in the diet. Forty-eight Leghorn laying hens were assigned randomly to one of four dietary treatments formulated to contain 0, 1.25, 2.5, and 5.0% CLA. The fatty acid composition of yolk lipids was altered by dietary CLA, with a decrease in unsaturated fatty acids (palmitoleyl, linolenic, and arachidonic acids). The amount of CLA in eggs increased linearly with amount of dietary CLA. [Delta]9- and [Delta]5- Desaturase activities were lower in livers from hens fed the 5% diet than in livers of hens fed the 0% diet. [Delta]6-Desaturase activity was very low in livers of hens in all groups. In summary, dietary CLA decreases the amount of unsaturated fatty acids in chicken eggs with a corresponding decrease in desaturation activity in the hen liver microsomes.

Download or read book Lipid Peroxidation Research written by Mahmoud Ahmed Mansour and published by BoD – Books on Demand. This book was released on 2020-01-22 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lipid peroxidation is the major molecular mechanism that induces oxidative damage to cell structures and is also involved in the toxicity process that leads to cell death.Lipid peroxidation is a chain reaction initiated by the hydrogen abstraction or addition of an oxygen radical, resulting in the oxidative damage of polyunsaturated fatty acids (PUFA). PUFAs are more sensitive than saturated fatty acids because of the presence of a double bond adjacent to a methylene group that makes the methylene C-H bond weaker and therefore the hydrogen is more susceptible to abstraction. This leaves an unpaired electron on the carbon, forming a carbon-centered radical, which is stabilized by a molecular rearrangement of the double bonds to form a conjugated diene, which then combines with oxygen to form a peroxy-radical.In pathological situations the reactive oxygen and nitrogen species are generated at higher than normal rates, and as a consequence, lipid peroxidation occurs with deficiency of endogenous antioxidants as alpha-tocopherol deficiency or reduced glutathione. In addition to containing high concentrations of PUFAs and transition metals, biological membranes of cells and organelles are constantly being subjected to various types of damage.This book presents systematic and comprehensive reviews on free radicals and their involvement in lipid peroxidation with special emphasis on their important role in different diseases.
