“…In some diets, inclusion level of fat or oil may reach up to 8% or more. Some researchers have shown the potential of vacuum coating for increasing fat content post pelleting (Lamichhane et al, 2015). This technique is not common in commercial broilers feed mills.…”

Commercial broilers have a short production cycle and a high requirement for energy (3000 kcal/kg in starter phase and 3200 kcal/kg in finisher phase). Therefore, the need to add energy rich lipids to their diet is inevitable. Digestibility of fat depends on its multiple properties: chain length, the composition of fatty acids, ratio of saturated/unsaturated fatty acids and free fatty acids. The high cost of vegetable oils and less availability due to their consumption in human diet are the main reasons for searching cheaper alternative fat sources. Animal oils like poultry and fish oil are the by-product of rendering plants and after refining, they are used in poultry diets as an energy source. Due to presence of impurities and free fatty acids, the digestibility of animal fat is less. There is a limited amount of bile acids and lipase available during early age and when birds are reared on high energy diet (finisher phase). Supplementation of emusifier or lipase in broilers diet increase fat utilisation. Emulsifiers increase fat digestibility by increasing active surface area of lipid droplets. Lysolecithin and Lysophospholipids are produced from hydrolyses of lecithin and phospholipids by phopholipase A2. The bile acids mainly compose of cholic acid, hyodeoxycholic acid and chenodeoxycholic acid and have strong emulsification properties. Triacylglyceryl acylase (lipase) is an enzyme involved in catalysis and the hydrolysis of lipids. It can be concluded that use of emulsifier and lipase in broilers diet improves growth performance, nutrient digestibility and intestinal histology in broilers.

“…The use of a deeper hydrobarothermal treatment together with vacuum emulsification of liquid components and fat will make it possible to create compound feeds with programmable properties, which are maximally adapted for different breeds of valuable fish [10,11]. An increase in the protein and fat complex in the most digestible forms, obtained as a result of a new combination of hydrobarothermal treatment and vacuum emulsification, will make it possible to obtain highly efficient biologically safe compound feeds that exceed foreign analogues in digestibility by 10-12 %, increasing the competitiveness of compound feeds.…”

The subject of research is kinetics of vacuum deposition of liquid components on extruded fish feed pellets. The kinetic regularities of the vacuum deposition process under investigation are established and the choice of rational modes of vacuum deposition of fat components in preparing compound feeds for valuable fish species is justified. The use of vacuum deposition of fat components on extruded feed for valuable fish species has led to the possibility of increasing the fat content up to 40 %, reducing the crushing of feed by 10 %. Improving the physical characteristics of finished compound feed (a moisture content of 10-12 %); increasing the penetration level of liquid components by 25-30 %; maintaining a dry surface of the extrudate; reducing pathogenic microflora to 0 are included. It was revealed that the amount of vacuum in working chamber of sprayer is the most important parameter affecting a fat leakage factor, and the amount of vacuum of 0.020 MPa provides intensive penetration and significantly reduces a fat leakage factor.
