Use of iodine and selenium enriched fodder rations for production of fortified young lamb
The article is devoted to preventive measures to eliminate the problem of dysmicroelementosis in order to increase the productivity of young sheep. The article presents the results of studies of the influence of feeding rations on the growth and development of young sheep of the Edilbaev breed, on the level of their meat productivity and the qualitative characteristics of biologically fortified lamb. Feed additives based on Yoddar-Zn and DAFS-25 were added to the main ration of lambs at the age of four months, once a day, being added into a fodder mixture with concentrates. For the experiment the herd of lambs was divided to four groups of 25 heads each.The changes in live weight at the age of four, five, six and seven months were analyzed, and it was found that at the age of seven months, the absolute average weight gain in the experimental groups varied from 3.45 kg to 4.49 kg, in the control group it was 3.1 kg, while the largest live weight gain was recorded in group III which received both feed additives based on Yoddar-Zn and DAFS-25.There were no significant differences in the parameters of body measurements, with the exception of group III, where the chest circumference increased by 7.2%, and the height of a lamb at the withers increased in average by 8.1%. It was found that group III had the highest meat density coefficient, equal to 3.9, and the cross-sectional area of m. Longissimus dorsi was equal to 13.61 cm2. It was noted that the amount of free amino acids of the lamb group III is 18.8% higher than the meat of the control group. The lamb obtained from the animals of the experimental groups showed a higher protein content and less fat. The ratio of water to protein in all samples was slightly higher than 3.7, which corresponds to the Federa number for meat raw materials. Enriching the rations of the Edilbaevskoy sheep with feed additives Yoddar-Zn and DAFS-25 promotes the stimulation of growth and development of animals, increases the productivity and nutritional value of lamb
The study of proteotomic profile of mutton with consideration to the influence of feed combinatorics
The present article is devoted to the search for markers that attest the changes in the protein profile when fattening the lambs with enriched diets, taking into account tissue specificity. The purpose of scientific research was to expand scientific knowledge about the influence of essential trace elements of organic origin in the diet of lambs on the marker-proteins of skeletal muscle tissue, of myocardium and renal cortical substance. The objects of research were the tissues of the m.L.dorsi skeletal muscle, myocardium and cortical substance of the kidneys in lambs of the Edilbaev breed. These lambs received a diet with organic trace elements (iodine, selenium, silicon). To study the effect of microelements in the diets of lambs on change in marker-proteins, we ran the studies of the skeletal muscle, myocardium and cortical substance of the kidneys of lambs, using the method of two-dimensional electrophoresis. When searching for proteins which mark the action of organic additives in the fattening diet of lambs within the tissue of the myocardium and the cortical substance of the kidneys, a number of differences were noted; no pronounced effects were observed in the skeletal muscle. Enrichment of the diet of lambs with selenium derivatives led to a change in the protein composition in the kidneys cortical substance for some isoforms of selenium-containing proteins and related enzymes of the glutathione cycle. Reaction in this process of thermal shock proteins, utilization of aflatoxins and changes in proteins of energy metabolism within mitochondria of kidney cells was also revealed. The determination of functional activity, or immunofermental analysis of glutathione peroxidase 3 count in the blood, can be a promising biomarker for controlling the level of selenium digestion and the count of selenium in blood as a more rapid and cheap method in comparison with the proteomic technologies. And for assessing the rate of digestion and fixation of iodine, it seems promising to determine it via the activity of mitochondrial superoxide dismutase [Mn]. In the myocardium, the effect of digested feed additives mainly affected the mitochondrial apparatus, which changed its functional orientation, with the activation of several other metabolic cycles. These results are prerequisites for obtaining more fundamental data on the effect of diets enriched with essential micronutrients on the molecular mechanisms that take place within the myocardial and kidney tissue of lambs. New data have been obtained on the effect of diets enriched with essential microelements on the molecular mechanisms occurring in the myocardial tissue and cortical substance of the kidneys of goats and sheep. The research results obtained by proteomics methods will be used for modeling and targeted adjustment of diets in order to obtain raw materials with the necessary technological characteristics
A Hierarchy of Scheduler Classes for Stochastic Automata
Stochastic automata are a formal compositional model for concurrent
stochastic timed systems, with general distributions and non-deterministic
choices. Measures of interest are defined over schedulers that resolve the
nondeterminism. In this paper we investigate the power of various theoretically
and practically motivated classes of schedulers, considering the classic
complete-information view and a restriction to non-prophetic schedulers. We
prove a hierarchy of scheduler classes w.r.t. unbounded probabilistic
reachability. We find that, unlike Markovian formalisms, stochastic automata
distinguish most classes even in this basic setting. Verification and strategy
synthesis methods thus face a tradeoff between powerful and efficient classes.
Using lightweight scheduler sampling, we explore this tradeoff and demonstrate
the concept of a useful approximative verification technique for stochastic
automata
Expected performance of the ASTRI-SST-2M telescope prototype
ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) is an
Italian flagship project pursued by INAF (Istituto Nazionale di Astrofisica)
strictly linked to the development of the Cherenkov Telescope Array, CTA.
Primary goal of the ASTRI program is the design and production of an end-to-end
prototype of a Small Size Telescope for the CTA sub-array devoted to the
highest gamma-ray energy region. The prototype, named ASTRI SST-2M, will be
tested on field in Italy during 2014. This telescope will be the first
Cherenkov telescope adopting the double reflection layout in a
Schwarzschild-Couder configuration with a tessellated primary mirror and a
monolithic secondary mirror. The collected light will be focused on a compact
and light-weight camera based on silicon photo-multipliers covering a 9.6 deg
full field of view. Detailed Monte Carlo simulations have been performed to
estimate the performance of the planned telescope. The results regarding its
energy threshold, sensitivity and angular resolution are shown and discussed.Comment: In Proceedings of the 33rd International Cosmic Ray Conference

Abstract In order to reduce the time of feeding, increase the intensity of weight gain without hormones, antibiotics, anabolic drugs, as well as to obtain high-quality meat with marble structure, the authors studied the influence of ovarioectomy on the intensification of the metabolic processes in gilts. The experiments were carried out in the FGUPΒ βMummovskoeβ β the educational experimental enterprise of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy (RSAU β MAA named after K.A.Β Timiryazev), in the Atkarsky district of the Saratov region. Two groups of Duroc gilts (10 animals each) raised under the same conditions were studied. As a result of the experiment, the influence of ovariectomy on the level of insulinlike growth factor-1 (IGF-1) and indicators of metabolic processes in gilts were established. It is confirmed that stimulation of the the somatotropin/insulin-like growth factor (ST-IGF) system along with hereditary factors and the characteristics of feeding contributes to the development of muscle tissue. Stimulation of ST secretion with insulin-like growth factor facilitates the development of muscle tissue.An increase in IGF-1 level leads to the development of new muscle fibers and muscle hyperplasia. After surgery, the major factors of changes in meat and feeding indicators in gilts were the rise in the metabolic activity of muscle tissue and fat metabolism, enhancement of production of IGF-1, which has insulin-like action and ensures activation of the processes of cell proliferation and differentiation. Increase in IGF-1 level had a positive impact on meat productivity, chemical and biochemical composition of pork. Simultaneous triggering of the systemic catabolic and local anabolic reactions in gilts after ovariectomy contributed to obtaining higher nutritional value of meat.ΠΠ½Π½ΠΎΡΠ°ΡΠΈΡ ΠΠ»Ρ ΡΠΎΠΊΡΠ°ΡΠ΅Π½ΠΈΡ ΡΡΠΎΠΊΠΎΠ² ΠΎΡΠΊΠΎΡΠΌΠ°, ΠΏΠΎΠ²ΡΡΠ΅Π½ΠΈΡ ΠΈΠ½ΡΠ΅Π½ΡΠΈΠ²Π½ΠΎΡΡΠΈ ΠΏΡΠΈΠ²Π΅ΡΠΎΠ² Π±Π΅Π· ΠΏΡΠΈΠΌΠ΅Π½Π΅Π½ΠΈΡ Π³ΠΎΡΠΌΠΎΠ½ΠΎΠ², Π°Π½ΡΠΈΠ±ΠΈΠΎΡΠΈΠΊΠΎΠ², Π°Π½Π°Π±ΠΎΠ»ΠΈΡΠ΅ΡΠΊΠΈΡ
