The authors developed composition and innovative technology of a new specialized product in the form of a biologically active additive to normalize metabolic processes in the case of the musculoskeletal system damage. They obtained specialized product through innovative tableting technology providing high consumer properties, components preservation and its active principles. The technological solutions innovativeness enables to separate composition ingredients considering its chemical and pharmacological incompatibility, and to deliver it sequentially to various sections of the gastrointestinal tract at a given speed. Glucosamine sulfate as a part of the vitamin and mineral complex combining with minerals (micro- and macro-nutrients) – manganese sulfate, calcium hydroxyapatate, cholecoleceferol, zinc and magnesium oxides – have unidirectional functional properties related to the metabolism correction in case of the musculoskeletal system damage. Clinical investigations confirmed the vitamin and mineral complex effectiveness. The diet for children 8- 14 years old has included one capsule of the specialized product additionally three times a day. Children (3-7 years old) with the long tubular bones fracture have received one capsule twice a day. Authors tested the recipe and technological production parameters at the enterprises of the company “Artlife” under the conditions of international and domestic standards including GMP and guaranteeing the quality indicators and competitiveness stability.

Scientific research was based on certain morphometric indices of various trout groups, which allows us to draw conclusions about the effectiveness of fish feeding with Aller Aqua and Aquafeed Fischfutter. The main task of trout farming is to obtain a commodity trout for the shortest possible time. In this case, the intensity of the growth of rainbow trout leads to the absence of feed, which is used in its cultivation. For active growth and development of fish, a high level of protein in the stern is required, which should be used specifically for plastic exchange, and not for the energy organism. Inner-shell left arms inviting them to optimize their chemical composition of feed, but they are energetic, perform in the body of fish a number of other vital functions: structure, regulatory and others, and serve as precursors of many biologically active substances that have validity and hormones. While growing rainbow trout, it is necessary to take into account its phenotypes of characteristics, which show that the level of breeding stability of the fish population and determines the attractiveness of products on the consumer market. The composition of feed primarily affects the metabolism of fish, which determines the intensity of their growth and development, and is also realized by trout. Fodder for the cultivation of salmon fish are made from industrial fishing waste. An economically viable alternative source of raw materials serves vegetal products (oils, sunflower proteins, soybeans, maize glutenin, and others), which, however, do not have a forage base of predatory fish appearing in natural waters. At present, the influence of different compositions on the morphometric and physiological biochemical characteristics of the culture, especially salmon, is actively studied, but these problems remain unchanged. The dynamics of the intensity of growth and development of rainbow trout is ensured by the feeding regime of fish. The publication of the published differences in the nature of the massif and the flow of rainbow trout species, which ensure the use of Aller Aqua and Aquafeed Fischfutter mixed fodders.

We examined the relationship between five stages of ovarian growth and development and hepatic microsomal thyroxine (T4) deiodinating activity in rainbow trout, Oncorhynchus mykiss, held in the laboratory at 11.5°C. Thyroxine outer-ring deiodination (T4ORD) activity, which forms biologically active 3,5,3'-triiodothyronine (T3), was low when the gonadosomatic index (GSI = (ovary mass X 100) / body mass) was below 0.2 (stage I, previtellogenesis), but rose sharply between GSI values of 0.2 and 0.3 (stage II), when oocyte Balbiani activity, RNA synthesis, and endogenous vitellogenesis were maximal. Hepatic T4ORD activity was again low during exogenous vitellogenesis at GSI values of 0.3-12, which correspond to stages III-V. Hepatic T4 inner-ring deiodination (T4IRD), which forms biologically inactive 3,3',5'-triiodothyronine, was detected only at stage II. Plasma T3 concentrations were significantly higher at stage II than at stage IV (primary yolk globule formation). Our data indicate changes in systemic thyroidal status at stage II and are consistent with a role for T3 in early oogenesis in trout. Enhanced hepatic T3 production at the late Balbiani stage may be required for oocyte development.
