Birds Feed Linseid Oil
Crespo and Esteve (2001) showed that birds fed tallow presented higher values of SFA, mainly mirystic, palmitic, and stearic acids (C14:0, C16:0, and C18:0), than those fed olive, sunflower, or linseed oil. Birds fed with olive oil had a substitution of these SFA (mainly stearic acid) by oleic acid. Thus, birds fed olive oil presented the lowest values of stearic acid in all tissues. Birds fed sunflower oil showed higher values of linoleic acid (C18:2 n6) than those fed tallow, olive, or linseed oil, and compared with birds fed tallow, linoleic acid replaced myristic, palmitic, and oleic acids in all tissues, and stearic acid in thigh muscle. Birds fed linseed oil presented the highest value of linolenic acid (C18:3 n3) in all tissues. This fatty acid also replaced myristic, palmitic, and oleic acids in birds fed linseed oil compared with birds fed tallow, whereas stearic acid remained constant between these treatments in all tissues. …show more content…
The lowest values of n-6 fatty acids were found in thighs and breasts of birds fed linseed oil. Oleic acid was the predominant fatty acid in all tissues of birds fed tallow or olive oil, whereas in birds fed sunflower oil, linoleic acid was always the predominant fatty acid, and in those fed linseed oil, linolenic acid was the predominant fatty acid in

    During the storage period, smaller decreases (P < 0.05) in the content of PUFAs were observed in the treatments that received dietary lycopene compared to those who were treated with exogenous lycopene (Table 1). The same pattern of changes was found in total SFAs and MUFAs. In view of these patterns of changes, although lycopene, both endogenously and exogenously added, was effective in slowing down the changes in FA composition of trout during refrigeration storage, fatty acids' profile of fillets that received dietary lycopene supplementation showed higher stability during refrigeration storage. The results also showed that among all groups, the highest level of dietary lycopene (360 mg/kg feed) was the most effective factor in slowing down the changes of FAs contents (P < 0.05).…

    In this experiment, the Oil of Wintergreen is put into an Erlenmeyer flask containing sodium hydroxide to create sodium salicylate. The solution is then refluxed which means that the solution will be boiled in a base, then condensed in a condenser. This replaces the carbon on the ester at carbon 1, with an oxygen atom which will have an ionic bond with a sodium anion. This yields sodium salicylate which will be acidified in methanol (CH3OH) which will remove the sodium bonded to the oxygen, and switch it to a hydrogen atom bonded to the oxygen, making an alcohol group. This new product is salicylic acid. Acetic anhydride is added to the salicylic acid to add an acetyl group to carbon 2 which will create acetylsalicylic acid…

    We have came up with a formula of simple, edible oils that have effectively made the levels of very long chain fatty acids (VLCFAs) decrease greatly, and over time the levels dropped down to normal. The oils are derived from olive oil and rapeseed oil. The reason it is successful, is because of the oleic acid and erucic acid in the oils. These oils completely stop the enzyme that makes VLCFAs.…

    The research completed (August 2013), evaluates the effects of inserting an enzyme complex (amylase, protease, xylanase) on the performance, intestinal, and nutrient digestion of weaned pigs. Experiment one had 108 piglets (28 days weaning) feeding on 0, 100, or 150 ppm enzyme complex. 6 pigs, at the end, from control and supplemented feeds were examined for viscosity and stomach pH and volatile fatty acid concentrations of microflora in the colon. Experiment 2 used 6 crossbred barrows to test in 3 dietary treatments (Latin Square process). Enzymes have been used in livestock for many years, but are increasingly being used in corn feed for diet supplementation for poultry. The enzyme complex used in the experiment had 2000 Units of activity/gram of enzyme amylase, 40,000 U/g protease, and 20,000 U/g xylanase. These supplements were grinded into 1.5 mm bits and met levels of nutrients appropriate for the pigs. Experiment 1 had a meal corn control diet and two experimental (100&150ppm diets of complex). One important note is that the feed was not limited and neither was water. 6 pigs each from control and 150 supplemental were killed after two hours of eating. In experiment 2, 6 crossbred barrows outfitted with T-cannulas (thin tubes for insertion/extraction of agents), ate commercially twice daily in increasing amounts. After 12 days, they were given the “3 treatments”. Each treatment was 7 days. In experiment 1, pigs fed supplements with 150 ppm increased weight (p equaled .09) compared to the control. The results indicate that the enzyme mush improved the pigs’ body weight gain, energy, and dry excretions of the pigs. The dry matter suggests that the blend affected nutrient digestibility the most by breaking the plant cell wall and subsequently releasing the…

    For Example, eating a salad with fat free salad dressing inhibits absorption of phytonutrients and vitamins from the greens and vegetables. This happens because many nutrients are fat soluble especially vitamins A, D, E, and K, which our bodies need for numerous bodily functions. Essential fatty acids are vitally important for muscle conduction, nerve impulses, and brain health but our bodies do not make these fatty acids on their own we have to consume them through our diet. The two major essential fatty acids or EFA’s are omega 3 and omega 6. The typical modern diet is far too abundant in omega 6 and not so much in omega 3. If this happens the omega 6 chain will inhibit metabolism of the omega 3 chain which can cause poor brain function and health conditions such as: headaches, depression, cardiovascular disease and cancer. In comparison, if the diet is high in omega 3’s and low in omega 6’s, there is a decrease in health conditions and a preventative to those diseases. Taking an omega 3 supplement such as fish oil will help counter act an excess of omega 6 in the body. (An Introduction,…

    Saturated fats are defined as fats that contain triglycerides that contain only saturated fatty acids. They can be found in foods that contain cheese, lard, or butter. Unsaturated fats are fat acids that contain double bonded chemicals that eliminate hydrogen atoms. Trans – fatty acids are usually found in man made products. They are created in an industrial process that’s adds hydrogen to liquid vegetable oils to make them solid. This type of fat can be found in most fast food products. Hydrogenated fats are found in margarine and vegetable shortenings. They are created by the forcing of hydrogen into liquid oil. They are mostly used in processed foods such as baked goods.…

    According to “Face the Fats” (2013), the unhealthy fats are, saturated and trans fats, tend to be more solid at room temperature (like a stick of butter). The healthy fats are monounsaturated and polyunsaturated fats and they tend to be more liquid (like liquid vegetable oil). Saturated fat is found mostly in foods from animals and some plants. Polyunsaturated and monounsaturated fats are found mainly in many fish, nuts, seeds and oils from plants. Some examples of foods that contain these fats include salmon, trout, herring, avocados, olives, walnuts and liquid vegetable oils such as soybean, corn, safflower, canola, olive and sunflower. Both polyunsaturated and monounsaturated fats may help lower your blood cholesterol level when you use them in place of saturated and trans fats, Face the Fats (2013).…

    The first one is to choose healthy saturated fats over unhealthy fats if you need to consider the intake of fats. Plant fats are healthy fats if they have not been hydrogenated - - which is more harmful than not, but it does make the fat more solid when warm or at room temperature. Some samples of plant fats would be nuts, olives, or avocados. The types of oils that are better than animal source fats are that from olives, canola, or peanuts. Excess animal fats are unhealthy and lead to many diseases, which makes the plant fat more attractive for health…

    More nature, less chemical – this is what, generally speaking, organic food is about. The process of creating authentic food in line with organic principles starts on the farm and is kept all the way through production, processing, distribution and sales. The organic food market is regulated by strict EU and Member States legislation and all people involved in production of organic food must comply with the rigorous rules. To ensure consumer of a high quality and compliance with the organic farming regulation and to help them identify organic produce, an organic control bodies logos are placed on the packages. From 1st of July 2010 an EU organic logo (figure 1) is obligatory for all pre-packed food items. Other logos commonly used on Irish market are shown on fig. 2.…
