“Energy Products are high energy, standardised dietary fat products, based on pure vegetable oils and fatty acids.”
Vegetable oils and fats are an important constituent of feed rations. In terms of nutritional physiology they play an important role in feeding because they increase the energy density of the feed – they possess 2.3 times as much energy as carbohydrates. The biological importance of fats stems from their function as an energy reserve and thermoregulator in the form of depot fat. Fats have a protective function, act as carriers for fat-soluble vitamins and bind the dust in feed.
Marvesa’s products are modern energy-rich, standardised feed fat-compounds, based on pure vegetable oils and fatty acids. The fatty acid composition is important for optimal growth and carcass quality. The optimizing of the fatty acid composition is effected predominantly by the linoleic content (C18:2), which could be vary, according to application in pig-, poultry- and cattle feed, from 10 – 40%. Polyunsaturated fatty acids such as linoleic and linolenic acid (C18:3) are essential fatty acids. That means that they are not synthesised by animal’s body and must be supplied in the feed. Marvesa developed feed fat-compounds with a high content of triglycerides, such as palm oil and a resultant lower FFA content – for better energy supply and more safety. All products will be produced according to effective EU legislation and will be analysed and controlled by “positive release”.

Energy Product 15L is a high energy, standardised dietary fat product, based on pure vegetable fatty acids and oils. Noba 15L is a fat product with a linoleic -C18:2- level of 15%.
Lecithin may be produced from egg yolk, but more commonly used in aquafeed are soya and rape seed lecithin. It is well known that the phospholipids (PL) present in lecithin act as an emulsifier of lipids in the animal stomach and gut, but especially the nutritional benefits of lecithin is why fish nutritionists like to include it in fish and shrimp diets. Lecithin is widely used in feed for larval and juvenile stages of various species of fish and crustaceans, because those developing fish have a limited ability to the novo phospholipid synthesis.read more
Lecithin is a fat-like substance which can be produced from soya bean, rape or sunflower oil. After degumming the oil, the lecithin is extracted from the gum and then cleaned. Lecithin is a complex mixture of at least 60% phospholipids; the other constituents are triglycerides, phosphatidic acid, choline, tocopherols, etc. Lecithin has a positive effect on several metabolic processes, because phospholipids play an important role in such processes. The main effect of lecithin is that it works as an emulsifier.read more
