This book was released on 2005 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Conjugated linoleic acid (CLA) refers to a class of positional and geometric isomers of octadecadienoic acid (C18:2) with conjugated double bonds found primarily in milk and meat products from ruminant animals. Several studies have shown that dietary intake of CLA can have positive health benefits, including antiadipogenic, antidiabetogenic, anticarcinogenic, and antiatherosclerotic properties and other desirable effects on bone growth, lipid metabolism and gene expression. Hampshire x Dorset lambs (n = 46) were used for this project. Hampshire x Dorset Iambs (n = 46) originating from the OARDC flock in Wooster, OH were used for this project. The supplementation of oil in the Iambs' diets was evaluated during two different stages of growth. The first stage was the pre-weaning, which in this study refers to the time the lamb is born through weaning including the transition period (time from weaning until lambs were allotted to a finishing pen). The second stage was from the time the lamb was allotted to a finishing pen until it reached the targeted endpoint and was harvested. Pre-weaning oil supplementation consisted of 2% soybean oil and 1% marine algal oil, and post-weaning oil supplementation consisted of 2% soybean oil and 1% linseed oil. Additionally, the effects of dietary oil supplementation to lambs on the retail case life of fresh lamb, and the stability of CLA in two processed, value-added meat products was determined. Supplementing ewes with PUFA while they are nursing lambs did not result in increased CLA levels in the muscle or subcutaneous fat of the lambs when they were harvested. Additionally, supplementing the lambs with PUFA during the growing and finishing phases (post-weaning) did not increase CLA content of the muscle or subcutaneous fat. There were trends for wethers to have more cis9 trans 11 CLA and total CLA in longissimus dorsi, and ewe lambs had significantly more trans10 cis12 CLA in subcutaneous fat, but all of these differences were small and may not play an important role in the nutritional benefits of consuming lamb products. Increasing PUFA in the diets did not result in negative effects on retail case life of fresh lamb. Conjugated linoleic acid content was stable in muscle tissue during mechanical and thermal processing techniques applied to value-added, further processed meat products.

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 The Return of W3 Fatty Acids Into the Food Supply written by Artemis P. Simopoulos and published by Karger Medical and Scientific Publishers. This book was released on 1998-01-01 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique publication for the first time brings together scientists from academia, government and industry to discuss the role of omega-3 fatty acids in health, the need to reintroduce them into the food supply, the methods by which this can be accomplished and the state of research. With the domestication of animals, there has been a change in animal feeds, which in turn transformed the composition of meats, particularly the content of essential fatty acids. Changes similar to those in meats have occurred in the composition of eggs, poultry and in fish from aquaculture. Up-to-date reviews on the role of omega-3 fatty acids in health, cardiovascular disease, bone remodeling relative to osteoporosis and in patients with retinitis pigmentosa emphasize the need for a balance of omega-6 and omega-3 fatty acids in the food supply. The reintroduction of omega-3 fatty acids into food products is discussed, and the methods involved in their production as well as their metabolic effects on human beings and companion animals are outlined. Overall, the papers presented indicate the necessity to establish recommended daily intakes for both omega-6 and omega-3 fatty acids. Furthermore, there is a need to redefine food safety; changes in food composition must also be taken into consideration. This unique publication is a valuable source for physicians, nutritionists, dietitians, veterinarians and agriculturalists, as well as for all those concerned with aspects of food production, food technology, food policy and consumer issues.
Download or read book Conjugated Linoleic Acid Cla written by Ondon Benny and published by Independently Published. This book was released on 2024-01-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: CLA is classified as an omega-6 fatty acid, which is a specific category of fatty acid. Naturally present in ruminant animal flesh and dairy products (e.g., sheep, goats, and cows) is this substance. Contrary to the majority of unsaturated fatty acids, CLA possesses a conjugated double bond system in which the double bonds are not separated by a single bond. Several studies have investigated the potential health benefits of CLA; these findings indicate that CLA might influence body composition, weight management, and overall health in a positive way. Notably, although some evidence supports these prospective benefits, the research is inconclusive; further investigations are required to comprehensively comprehend the mechanisms and enduring consequences of CLA supplementation. CLA supplements are commercially available and are frequently utilized for a variety of purposes, such as weight loss and muscle gain. Before incorporating CLA or any other dietary supplement into your regimen, it is crucial to seek the advice of a healthcare professional. This is especially true if you have any pre-existing health conditions or are currently taking medications.
