THE FORMATION AND QUALITY OF MEAT OF CATTLE BREEDING AND POULTRY FARMING

abstract 1331709026 issue 133 pp. 310 – 319 30.11.2017 ru 516
In order to ensure import substitution and threshold values of meat production, it is necessary to stabilize the livestock of animals and introduce intensive technologies. In conditions of arid steppes, the animals of Kalmyk, Hereford and Aberdeen-Angus breeds are best suited to stall-pasture technology. Before weaning from mothers at 7-8 months of age, their offspring is grown without additional feeding, just mothers’ milk. Therefore, the growth rate of suckling young animals rarely exceeds 850 grams of daily growth, while the live weight reaches 400-450 kilograms at the age of 18 months, with some advantage in favor of the young generation of Hereford breed. Using the intensive 9- months growing at the fattening complex with feeding from the self-feeders ensured the average daily gain in the Kalmyk bull-calves at the level of 1398 grams, and for the Aberdeen-Angus and Hereford breeds the growth is 1533 grams. The highest growth energy, live weight (661 kilograms), was with Hereford bulls. From bulls of the native Kalmyk breed with intensive technology of growing, a heavy body weight increase of 331 kilograms at 18 months of age was obtained. All tested samples of meat according to microbiological indicators comply with the requirements of the Technical Regulations

TESTING OF HOMOGENEITY OF PAIRED SAMPLES

abstract 1231609047 issue 123 pp. 708 – 726 30.11.2016 ru 515
The article begins with the letter of the chief engineer of chemical plant near Moscow. He requests to analyze of data by means of modern statistical methods and give an opinion on the presence (or absence) of the relationship between the two methods of determining the viscosity of the mastic. For each of the batches of mastic It was presented two numbers - the viscosity measurement results of the two methods. These numbers form two paired samples. We want to install, give whether two specific methods similar results. The true values of viscosity in different batches are not equal. Their difference is not allows us to combine the results of the first measurement method in first sample, the results of the second method - in the second sample, as we can do in the case of testing the homogeneity of two independent samples. For solutions to this problem we discuss four statistical criterions, based on a study of the differences between corresponding values in two paired samples. We test the hypothesis of equality 0 of median of these differences (sign test) and of equality 0 of the mathematical expectation of these differences. Hypothesis of testing of equality of the distribution functions of two paired samples is reduced to the hypothesis of symmetry of the distribution function of these differences with respect to 0. In the alternative of the shift is proposed to use the Wilcoxon signed rank criterion. In the total alternative is proposed to use criterion of the omega-square type which is developed by the author of this article

WAYS OF OPTIMIZING THE AMOUNT OF CHEMICAL ADDITIVES IN POROUS ARBOLITE CONTAINING FOAMED POLYSTYRENE GRAVEL AGGREGATE

abstract 1281704017 issue 128 pp. 258 – 267 28.04.2017 ru 515
The article deals with studying the ways of optimizing the amount of chemical additives in the wood-concrete material, i.e. arbolite, which contains foamed polystyrene gravel aggregate. To make arbolite honeycombed structure more conglomerated a nonreactive aggregate, i.e. hogged chips, has been partially replaced with foamed polystyrene gravel aggregate which has a mean particle size equal to a concrete pocket size. The article also deals with various additives to be used, taking into account the nonreactive aggregate type and its quality, the composite density and its reinforcement level. All chemical additives have been chosen to make the initial material more porous, to produce a film covering the aggregate surface and to speed up the process of concrete hardening. To solve to above problems a series of experiments was carried out, the latter studied various combinations of factors changing at certain levels. The results of studying the foamed polystyrene gravel aggregate influence on the arbolite structure and its characteristics were used to make a choice of the arbolite composition. The main criterion of the optimal amount of chemical additives has been considered the arbolite strength. The experimental data processing has resulted in the finite regression model which describes the chemical additive amount influence on the arbolite strength. The tables in the article show the levels of technological factors varying and the matrix of planning the experiments to be carried out in order to optimize the chemical additive amount. As a result of the research accomplished the optimal amount of chemical additives has been determined which enables to produce the arbolite with some foamed polystyrene gravel aggregate in its composition
