Efficacy of natural biosurfactant LYSOFORTE® over chemical emulsifier Glycerol Polyethylene Glycol Recinoleate (PGER) – a performance study ParthaPratim Das, Amitabh V Pandey and K JayaramanAugust 13, 2015 1:28:01 PM IST | India
Present day broiler production is projected towards maximizing performance with sustainable input costs and combating present day challenges of increased raw material price. For this, proper utilization of nutrients is essential. In commercial broiler production practice, fat/oil is usually added to meet the bird’s energy requirement. Fats and oils from external sources as well as from raw materials comprising the total ether extract of diet are the costliest part of the diet. So, effective utilisation of this nutrient is very significant for substancial economic benefit. Fat reduces the rate of food passage through the gastro intestinal (G.I) tract and thus facilitates better absorption of all nutrients present in the gut. Absorption of nutrients, especially using fats and oils, is primarily accomplished by bile salts that act as a natural biosurfactant in the gut. To attain current trend of maximised broiler productivity, the natural bile source inside the bird is not enough to fullfill optimum ether extract digestion and absorption. Young birds recycle bile salts less efficiently and produce fatty acid binding proteins in less quantity. As such, there is an opportunity to optimize digestion and absorption of ingested fat by improving its emulsification and ensuring more uniform and smaller micelle development.view more»
