PARTICULARLY THE EXCHANGE OF CHEMICAL ELEMENTS IN FISH WHEN ADMINISTERED IN THE DIET AND DIETARY SUPPLEMENTS OF IRON NANOPARTICLES [№ 6 ' 2017]
Recent advances in animal nutrition has significantly increase the range of use of dietary supplements, a positive effect on growth rate, feed conversion and resistance of the organism. Research on warm-blooded animals have shown the promise of joint use of dietary supplements and metal nanoparticles in feeding, however, the experimental work in fish farming on the subject are rare. We first studied the prospects of joint use of preparations of nanoparticles of iron and supplements in the feeding of fish and showed that their simultaneous use enhances performance of weight gain up to 28% compared to control. With the introduction in the diet of Fe NPS (nanoparticles) noted a significant increase in concentrations of macro— and micronutrients compared to control: calcium 42% (P<0.001), potassium 8.2% (P<0.05), magnesium 19% (P<0.001), sodium 27% (P<0.001), phosphorus by 32% (P<0.001), chromium by 6% (P<0.05), copper 18.8% (P<0.05), cobalt 6% (P<0.05), manganese by 72.2% (P<0.001), selenium 17.5% (P<0.001) and zinc by 34% (P<0.001). When added to the diet of Fe NPS and the enzyme, Rovabio XL showed a significant increase in sodium concentration by 13% (P<0.01), copper 14% (P<0.05), cobalt 9.6% (P<0.05), manganese 26.6% (P<0.05), selenium 9.2% (P<0.01) and zinc 42.5% (P<0.001) and decreased concentration of calcium by 26% (P<0.001) compared to control. When included in the ration Fe NPS and Bifidobacterium bifidum showed a significant increase in the content of elements in comparison with the control: the calcium 148% (P<0.001), and potassium 62% (P<0.001), magnesium 111% (P<0.001), sodium 100% (P<0.001) and phosphorus by 100% (P<0.001), chromium 36.8% (P<0.001), copper 84% (P<0.001), cobalt 174% (P<0.001), iron 58% (P<0.001), manganese 270% (P<0.001), selenium by 82% (P<0.001) and zinc by 125% (P<0.001). Analysis of the content of toxic elements in the fish body showed that for the experimental groups was characterized by a decrease in the concentration of elements except lead. Thus, it is established that the joint inclusion in the diet of carp nanoparticles of iron and dietary supplements positively affects the accumulation of macro— and micronutrients and does not affect the accumulation of toxic elements in the body of a fish, with the best performance on the dynamics of live weight was obtained by joint use of Fe NPS of the drug and probiotic Bifidobacterium bifidum.

USE SUPPLEMENTS AND IRON NANOPARTICLES IN THE CARP FEEDING [№ 6 ' 2015]
Currently, the practice of using feeds with different kinds of dietary supplements. In this paper we study the effect of fine iron powder, the enzyme preparation RovabioXL, probiotic preparation bifidobakterin bifidum (Bifidobacterium bifidum) on the growth, development and hematology carp at their joint use. Object of research are carp (n= 50), age (0+), with the sample of 10—15g, grown in a cage farms Ltd. "Lake" Orenburg. Fe nanoparticles obtained at the Institute of Energy Problems of Chemical Physics, Russian Academy of Sciences (Moscow) and synthesized by high-temperature condensation installation Migun technology MJ Gene and AV Miller. The size of the nanoparticles 100nm± 2nm. The studies found that the combined use of nanoparticles and probiotic bifidobakterin bifidum increases the growth rate by 28% relative to control. Hematologic parameters of blood in all the experimental groups were within the physiological norm. In the analysis of blood parameters of the experimental groups was recorded similar picture of changes in hemoglobin and red blood cells: the second week of the experiment there was a decrease in hemoglobin level and the number of red blood cells compared to the control group in I experienced a 7 and 29%, in II— 16 and 19% inIII— 5 and 34%, respectively. In the fourth week we have noted the increase in the level of hemoglobin and red blood cell count in the I and III experimental groups: I— 4and86%, inIII— 14and59%, respectively. In the sixth week, recorded a slight decrease in hemoglobin levels compared to the control in the I— 0.7%, inII— 6.3%, inIII— by2.7%, and a significant reduction in the number of red blood cells in theI— 38%, inII— 34%, in theIII— 25%. Changing the number of white blood cells had a similar pattern changes in the number of red blood cells and hemoglobin concentration. Thus, in the second week of the experiment there was a decrease of leukocytes compared to the control inI— 13%, inII— 13%, in theIII— 12%; in the fourth week we noted an increase in the number of leukocytes in theI and GroupII— 49%, in theIII— 12%. Fixed constancy protein composition of plasma and absence of inflammatory processes in the body, as evidenced sedimentation rate of erythrocytes (2—5mm/h).

THE USE OF EXTRUDED FEEDS WITH THE ADDITION OF METAL NANOPARTICLES IN FISH FEEDING [№ 10 ' 2012]
In the course of the research assessed the biological value of extruded feeds with the addition of metal nanoparticles, revealed significant changes concentrations in the body of the carp of microelements and essential trace elements.
