Download or read book Milk Conjugated Linoleic Acid Response to Fish Oil and Sunflower Oil Supplementation to Dairy Cows Managed Under Two Feeding Systems written by Deidra O. Felton and published by . This book was released on 2007 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earlier research showed that conjugated linoleic acid (CLA) content in milk fat is highest when cows' diets are supplemented with a blend of fish oil (FO) and linoleic acid-rich oils. The objectives of this study were to compare the effect of FO and sunflower oil (SFO) supplementation on milk cis -9, trans -11 CLA content and its temporal change when dairy cows managed on pasture or in confinement. Fourteen Holstein cows were assigned into two treatment groups: cows grazed on alfalfa-grass pasture (PAS) or were fed a corn silage-alfalfa hay mix ad libitum (LOT). Both groups were supplemented with 8.2 kg/d grain supplement containing 640 g of FO and SFO (1:3 w/w). Milk samples were collected every third day and during the last 3 days of the experimental period. Milk yield was higher (P 0.05) with the LOT diet compared with the PAS diet. Milk fat percentages and yields were similar (P 0.05) for the two diets. Treatment diets had no effect (P > 0.05) on milk trans C18:1 concentrations (10.64 and 9.82 g/100g of total fatty acids (FA) for the LOT and PAS, respectively) or yields (60.65 and 64.01 g/d), but did affect isomer distributions. Concentration (g/100g of total FA) of vaccenic acid (VA) was lower (P

Download or read book Effects of Supplementing Grazing Dairy Cows with Fish Oil and Linseed Oil on Milk Conjugated Linoleic Acid and Omega 3 Fatty Acids Content written by William Brown and published by . This book was released on 2007 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: A considerable amount of evidence has accumulated in supporting the view that conjugated linoleic acids (CLA) and omega-3 fatty acids (FA) have beneficial health properties and that the consumption levels of these FA is insufficient in most western diets. In view of their benefits, there has been a considerable interest in enhancing milk and dairy food products with these beneficial FA. The objective of the first trial was to determine the effect of supplementing grazing dairy cows' diet with fish oil (FO) and linseed oil (LSO) on milk c9, t11 CLA and omega-3 FA. Sixteen Holstein cows (170 ± 19 DIM) were divided into 2 groups (n=8 per treatment) and fed a basal diet (8 kg/d; DM basis) consisting of corn, soybean meal, molasses, vitamin/mineral premix plus 800 g saturated animal fat (CONT) or a basal diet plus 200 g FO and 600 g LSO (FOLSO). All cows grazed together on Sudan grass pasture for ad libitum and were fed the treatment diets for 3 wks. Cows were milked twice a day and milk samples were collected during the last three days of the trial. Milk production (24.89 and 22.45 kg/d), milk protein percentages (2.76 and 2.82) and milk protein yield (0.68 and 0.64 kg/d) for the CONT and FOLSO diets, respectively, were not affected ( P > 0.05) by treatment diets. Milk fat percentages (3.90 and 2.86) and milk fat yields (0.97 and 0.64 kg/d) were lower ( P

This book was released on 2007 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, there has been considerable interest in the potential health-promoting properties of conjugated linoleic acid (cis-9, trans-11 CLA), a fatty acid produced naturally in ruminant animals, and omega-3 fatty acids. The primary objective of this trail was to determine the effects of varying levels of linseed oil (LSO) on grazing dairy cows' diet on milk cis-9, trans-11 CLA and omega-3 fatty acids content. Twelve Holsteins cows in mid lactation (150 ± 19 Days in milk) were placed on alfalfa based pasture and assigned into four treatment diets using a 4X4 Latin square design with 3 wk period. Treatment diets were: (1) control grain supplement (CONT); (2) control grain supplement containing 170g LSO (LSO1); (3) control grain supplement containing 340g LSO (LSO2) and (4) control grain supplement containing 510g LSO (LSO3). Grain supplements were offered at 7 kg/d twice daily. Additional 100 g/d of algae, divided evenly between the two feeding times, were added to every treatment diet. Milk samples were collected during the last three days of each period and analyzed for chemical and fatty acids composition. Treatment diets had no effect on milk production (18.93, 18.50, 19.60 and 19.10 kg/d for treatment diets 1 to 4, respectively), milk fat percentages (3.23, 3.44, 3.35 and 3.27) and milk protein percentages (3.03, 3.19, 3.12 and 3.08). Milk cis-9, trans-11 CLA (1.12, 1.18, 1.39, and 1.65 g/100g fatty acids for treatment diets 1 to 4, respectively), vaccenic acid (VA, trans-11 C18:1; 3.39, 3.62, 4.25, and 4.89 g/100g fatty acids), and total omega-3 fatty acids (0.86, 1.09, 1.26, and 1.25 g/100g fatty acids) concentrations were linearly increased (P

Available in PDF, EPUB and Kindle. Book excerpt: As health problems such as obesity, heart disease and diabetes increase in many developed and developing countries, the food industry has come under mounting pressure to improve the nutritional quality of its products. Particular attention has focused on the health problems associated with saturated fats in food and on the potential health benefits of increasing monounsaturated and polyunsaturated fat content. Summarising key research in this field, this important collection reviews both the influence of dietary fats on health and practical strategies for improving the fat content of food products. Part one reviews the evidence on the links between dietary fats and health. There are chapters on the links between saturated fatty acid intake, obesity, coronary heart disease, diabetes and cancer, as well as the health benefits of monounsaturated fats, polyunsaturated fatty acids (PUFAs) and conjugated linoleic acids (CLAs). Part two then discusses ways of reducing saturated fatty acids in food. It includes chapters on the role of lipids on food quality and ways of gaining consumer acceptance of low-fat foods, as well as chapters on improving fatty acid composition in dairy products and milk and the use of fat replacers. The final part of the book reviews ways of using polyunsaturated and other modified fatty acids in food products. It includes chapters on developing and using PUFAs as functional ingredients and ways of improving the sensory quality of products incorporating modified fats. With its distinguished editors and international team of contributors, Improving the fat content of foods is a standard reference for nutritionists and product developers in the food industry. Reviews the influence of dietary fats on health Investigates practical strategies for improving the fat content of food products Discusses improving the fat content of foods whilst maintaining sensory quality
