| dc.description.abstract | The article is devoted to the problems of determining quality and safety of extruded feed additive (EFA) with algae. It is used in the production of mixed feed and premixes. It is proved that the safety of finished food products depends on the safety of feed and feed raw materials. The list of conditions for obtaining safe finished products is given. Today traditional methods of analytical chemistry, express and toxicological methods (marking, biotesting) are used for the analysis of feed safety. The expediency of use of brown algae in the composition of feed products is substantiated. The brightest representative ofbrown algae is Laminaria. The technology of using Laminaria algae in the composition of feed products in the form of extruded feed additive is proposed. The method of determination of organicity by methods of biotesting is given: biocrystallization method, determination of the oxidation-reduction potential index (ORP), organicity using Colpoda steinii culture. Indicators of organicity are given. An analysis of experimental samples biocrystalograms suggests that EFA is environmentally safe and do not endanger the environment or the health and life of animals and humans. When determining the ORP of the EFA with algae it was established that the product is easily digestible, since it has a biological compatibility with the animal organism. The expediency of using the process of extrusion to reduce the toxicity of algae is established. The application of the extrusion allows to add up to 15% Laminaria algae to the feed. The results of biological studies of EFA in vivo are presented, which indicate a high biological efficiency of the use of algal feed supplement in the composition of feed for young farm birds in the amount of up to 25%, since the average daily weight gain of rats increases and the cost of feed decreases. | |
