Research
& Development

The animal husbandry has been focussed on improving the technical performance of the animals. Therefore Marvesa partners with leading research universities and animal feed testing centres to conduct basic nutritional research and in-depth feed trials to understand the effect of our fat products on the technical performance of the animals. Our research is based upon questions from our customers. We endeavour to answer those questions with proven results. The development of our new products is also customer-focused, together with our customers we are looking for fat products that contributes to more effective and efficient feed formulations.

How can you improve fat digestibility?

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.

Effect of medium chain fatty acids on FCR and bacteria profiles in the gut of broilers

Many people in our industry talk about MCFAs or MCT. MCFAs means medium-chain fatty acids, which are fatty acids with a chain length of 6, 8, 10 or 12 carbon atoms. This means that we talk about C6-fatty acids, C8-fatty acids, C10-fatty acids or C12-fatty acids. These medium chain fatty acids are not bind with glycerine, they are in a free form as free fatty acids (FFA). MCT means medium chain triglyceride, this is an oil, sometimes it is called MCT-oil, for example palm kernel oil. Palm kernel oil contains high levels of C12-triglycerides. MCFAs have strong antibacterial properties.

Lecithin as a rich energy source with nutritional performance

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.
