Technologies for recycling mussel (Lat. Mytilus edulis Linnaeus; Lat. Mytilus galloprovincialis Lamarck)and seaweed wastes (Lat. Phyllophora nervosa) into feed additives – protein-mineral and mineral oneswith sea water adding were developed on the basis of the research results. The technology of producingfeed additives from marine hydrobionts, protein-mineral and mineral, is approved by two useful modelpatents of Ukraine: No. 34634 (2008) A23K1/75 “Method for producing feed additive from marinehydrobionts for poultry No. 42687 (2009) A23K1/10, “Method for producing feed additive from marinehydrobionts for poultry. In accordance with the study methodology control and test groups of broilerchickens were provided with staple ration for 8 days (aged from 12 to 20 days). From the 21st day till theend of the period (62 days in total) their ration was enriched by paste-like additives in the amount of 7 %to the staple ration. We used the additives in 2 ways: 7 % replacement of the staple ration with additivesand adding extra 7 % of additives to enrich the staple ration. Sea hydrobiont additives produced accordingto our own technology can be used when raising chickens as non-traditional source of proteins andminerals for staple ration. Enriching the ration of chickens by protein-mineral additive in the amount of 7% or replacing the ration by the same amount of the additive allows to increase their body weight gain by6,9 % as well as relative growth and conservation rate. Enriching the ration by mineral additive increasesbody weight gain of chickens by 4,9 %. |
