COMPARATIVE EVALUATION OF THE EFFICIENCY OF SYMBIOTIC FEED SUPPLEMENT IN RATION OF LOHMANN BROWN EGG CROSS CHICKENS

abstract 1211607090 issue 121 pp. 1473 – 1486 30.09.2016 ru 462
The purpose of the research is to compare the effect of a new symbiotic feed supplement created based on propionic and lactic acid bacteria with a widely used domestic and foreign enzyme-probiotic preparations in chickens 0-28 days of age of the Lohmann Brown egg cross. In the experiment, there were six groups of chickens: group 1 received basal diet (BD); group 2 – BD + symbiotic preparation; group 3 – BD + Bacell; group 4 – BD + Agrocell; group 5 – BD + Agroksil; group 6 – BD + Ollzaym Vegpro. Average daily gain, food conversion rate per 1g of weight gain, digestibility of organic matter, crude protein, crude fiber, crude fat, made up respectively: group 1 – 8.17, 1.91, 71.4, 58.3, 68.0, 81.1; group 2 ˗ 8.36, 1.90, 72.4, 60.2, 69.7, 88.1; group 3 – 8.13, 1.91, 73.1, 60.2, 69.7, 88.1; group 4 – 8.33, 1.86, 74.2, 62.5, 72.2, 87.6; group 5 – 8.50, 1.83, 77.3, 64.1, 73.4, 95.4; group 6 – 7.91, 1.92, 73.2, 67.5, 70.7, 94.3. The growth rate of chickens fed with symbiotic feed supplement was 2.3% higher than in the control and they showed the highest fiber digestibility. The chickens on diet with Agroksil enzyme efficiently raised growth rate (+4%) and reduced feed costs (-4.2%). Agrocell increased weight gain by 2% and reduce feed costs by 2.6%. The growth rate of chickens fed Ollazaym Vegpro was the lowest (96.8% of control), despite the fact that it increased significantly the digestibility of crude protein, but slightly improved the digestibility of other nutrients. Outcome: symbiotic feed supplement may be of interest as a means of increasing the productivity of chickens

SOIL PRODUCTIVITY OF DRAIN AGROLANDSCAPES DEPENDING ON THEIR MELIORATIVE CONDITION

abstract 1341710088 issue 134 pp. 1083 – 1095 29.12.2017 ru 462
In the soils of rice fields, eluvial gley processes develop, which are manifested in redistribution of silty particles along the profile, water-soluble humus, mobile compounds of iron and phosphorus. Most intensively, these processes are developed in meadowbog soils, confined to closed depressions of the plains plain. Meadow-black soils lying on elevated relief elements have more favorable physical, physicochemical and oxidation-reduction properties for cultivating rice and accompanying crops in crop rotation. The highest yield of rice is formed on high checks and higher at 12,4 c/ha than on low ones

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

abstract 1331709026 issue 133 pp. 310 – 319 30.11.2017 ru 465
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

APPROACHES TO JUSTIFICATION OF AN EXPERT SYSTEM IN THE DEVELOPMENT OF EPIPHYTOTICS ON WINTER WHEAT CROPS

abstract 1181604103 issue 118 pp. 1576 – 1586 29.04.2016 ru 466
The article examines the creation of the expert system in the development of epiphytotics in winter bread wheat sowing. Increasing the accuracy of the forecast epiphytotics should be based on the improvement forecasting of move daily temperature (minimum, maximum and average). In this case, the calculation algorithm must not be cumbersome. In the algorithm, there are indicators of cyclical annual variations of temperature, i.e. the change in average daily temperatures for the year. For the treatment method of local forecast of daily average temperatures during the year used data of meteorological station for 9 years. Having considered the main issues to epidemics of brown rust and its influence on the production of wheat cenoses, you can proceed to the modeling expert logic. The analysis includes the following indicators: cultivated variety; agricultural machinery (predecessor, fertilizer, pre-processing, and others.); general condition of sowing; phase of plant development at the time of the field survey; date of onset of the disease (if selected); prevalence of sowing at the time of observation. Installed that the purposeful creation of varieties of winter wheat resistant to the pathogen, it is necessary to carry out environmental testing stability as a latent breeding and recommended sources and sustainability of donors, which will allow to plan economic occupancy resistant genotypes of winter wheat

STUDYING THE REPRODUCTIVE POTENTIAL OF PLANTS OF BEZOSTAYA 1 WHEAT HAVING ADDITIONAL SPIKELETS ON THE LEDGE OF THE RACHIS

abstract 1201606046 issue 120 pp. 664 – 674 30.06.2016 ru 467
The article discusses the effect of additional spikelets in the variety of Bezostaya 1 on the realization of productivity of the examined plants. We traced the frequency of occurrence of multirov spikes and studied the effect of this phenomenon on the productivity and the main quantitative characteristics of the studied plants. The article demonstrates the structure distinction of productivity for abnormal and normal ears. Experience was one-way vegetation, planted in triplicate, time of experiment - 2013 - 2015 years. The study revealed that the most frequent was the emergence of 1-4 additional spikelets per spike. Some quantitative characters had a slight deviation, these include the number of spiked ledges on the kernek, spike length and plant height. To a large extent we increased the characteristic values such as the number of grains per ear, number of spikelets per spike, number of grains onto the ledge, head weight and the weight of grains spike. We significantly reduced weight of 1000 grains. It was revealed that more localized spikes were mostly in the middle, the most productive part of the ear. As a result, changes have affected not only the quantitative characteristics related to the productivity of the ear, but also its architectonic whole

MIGRATION FEATURES OF HEAVY METALS FROM WATER SOLUBLE SOIL COMBINATIONS IN DIFFERENT PARTS OF A SQUASH FRUIT

abstract 1251701021 issue 125 pp. 296 – 308 31.01.2017 ru 477
The accumulation of heavy metals was studied in different component parts of a White squash (skin and flesh, flesh, seed skin, seed kernel, peduncle). It is known that the basic source of feed for agricultural crops are mobile water soluble organic and mineral soil combinations which are polluted by heavy metals in different degrees. In the process of their migration they are able to accumulate in different parts of plants or to disperse. The mechanism of quantitative estimation of migration of heavy metals in direction of removal of mobile water soluble soil combinations to various parts of a White squash is developed by the author. The ranks of mobility of heavy metals are made from the most mobile manganese to the most indifferent iron. The model of estimation of mobility of the rest spectrum of heavy metals is chosen, namely: lead, cadmium, zinc, copper, nickel, cobalt in relation to manganese and iron. Basing on the position of a separate element in a mobile rank and its concentration it is possible to define the source of entering to a squash fruit. It may be water soluble soil combinations, irrigation water and atmospheric aerosols
