AGRONOMY
The paper highlight efficiency of standard nursery transplant producing of blue honeysuckle on the basis of recovering and accelerated propagation. This process lasts 15-16 months and it is divided into the following stages: introduction in culture in vitro, micro-propagation (proliferation) itself, rooting of microsprouts, adaptation to non-sterile conditions in the laboratory and completion of growing in the open ground. When introduced into sterile environment, growing medium Woodi Plant Medium, in comparison with traditional MurashigeSkoog medium, provided significant increase in the survival rate of explants which was 62.2 %. At the stage of micropropagation, appropriate spectral composition for microsprouts of sweet-berry honeysuckle was provided by light-emitting diode radiator with a combination of red, blue and white light 2 : 1: 1, respectively. Modified Murashige-Skoog medium appeared to be the most effective at this stage. When researchers added 1.0 mg/l 6- BAP and 0.5 mg/l kinetin, it increased significantly propagation coefficient of microsprouts appropriate for rooting. At the rooting stage, light-emitting diode radiator with combination of red, blue and white light 2 : 1 : 1, respectively provided significant increase in rooting ability of microsprouts up to 89.0%, in comparison with control group (76.0%). At the stage of adaptation, application of growing medium on the basis of highbog peat and post-planting spraying with HB-10 increased microplants establishment. These adaptation conditions have significantly increased the number of sweet-berry honeysuckle established plants. Completion of growing of established meristem sweet-berry honeysuckle plants in containers when applying growing medium on the basis of highbog peat and lowland peat (1:1) increased the yield of standard annual planting stock up to до 94.0 %. The suggested advanced biotechnological techniques that consist of five stages, allow to increase significantly the yield of the standard planting stock of sweet-berry honeysuckle in 5.5 times, to reduce the cost of planting stock on 15.2 %. The standard planting stock with closed root system was reduced to one vegetation period.
Efficient land use is achieved by the correct relation among agriculturally used lands (arable land, hayfields, pastures, etc.) which is the most appropriate for the conditions of Northern Kazakhstan structure of acreage and crop rotation. Crop change in the fields, all other conditions being equal, is more efficient than their permanent sowing; efficiency of fruit exchange is higher than the greater the difference in biology and technology of cultivated crops is. The researchers highlight the priority of grain industry development and transition to short-rotation crop rotation. The leading scientists of Kazakhstan indicate that market relations require a differentiated approach to crop cultivation not focusing on single-crop only. This assumes diversification of grain industry, production of high-protein crops, which are alternative to wheat. Crop rotation is important mean of plants and microorganisms influence on soil fertility. This is a biological factor of soil fertility reproduction. The research aims at defining the place of food, forage and technical crops (wheat, rye, pea, panic grass, buckwheat and oil plants) in crop rotations in relation to plant production diversification. The author explores the impact of some crops and their combinations on soil fertility and phytosantiary condition of soil. Scientific and industrial practice shows that implementation of these approaches in farming in steppe areas of Kazakhstan increases significantly crop yield.
БИОЛОГИЯ
Stability of phytosanitary situation in agrocenoses of crops is supported by entomophages that can restrict the growth of harmful species density. The paper reveals the assessment of the situation in concern of useful fauna on the oats sowings cultivated traditionally and on No-till technologies. Oat is an important food and feed grain crop. No-till technology implies the absence of mechanical tillage and seed sowing in stubble, what contributes to conservation of material and energy resources, soil fertility and environmental protection. The researchers found out that on average total number of ravenous entomofauna in a stalk oat on No-till technology was 1.6 times higher, than that in traditional technology for 2 years. The authors didn’t observe the impact caused by No-till technology on the number of some species of entomophages (Coccinellidae, lion aphids, Nabis, Orius, syrphids and spiders). The abundance of cereal aphids, which are the main food source of the most studied predators didn’t depend on the technology of oat cultivation in concrete years and on average.
The authors observe 4 ecological forms of a wolf in Kazakhstan. They are Siberian forest wolf (Canis lupus altaicus Noak, 1911), steppe wolf (Canis lupus campestris Dwigubski, 1804), desert wolf (Canis lupus desertorum Bogdanov, 1882) and mountain wolf (Canis lupus chanсo Gray, 1863). The wolves inhibit in the corresponding areas as forest, steppe, desert and mountains. Due to hunting and reducing of saiga population and domestic cattle the wolf population has been reduced significantly in Kazakhstan. At present time the legislation in concern of wolf is directed at its predation. There are no administration mechanisms for wolf management in Kazakhstan. Otherwise, there are amendments in legislative acts observed, which are aimed at changing the current situation. The author speaks about considering the issue about introducing the wolf into the list of hunting species and prohibition to use motor transport, snowmobiles and additional light sources at amateur hunting.
The author explored variability and system of genetic parameters in determination of ear length in F1 hybrids of soft winter wheat on the basis of diallel crossbreeding. Diallel crossbreeding is considered to be the most general and most informative for genetic analysis of quantitative traits in plants. When doing such crossbreeding, the researcher is provided with the complete set of all gene combinations of forecrops. The researcher faces the difficulties in crossbreeding, but he receives the rich initial material for crop breeding. The article describes the material about 5 varieties and 1 line of domestic and foreign breeding and their diallel hybrids. The study was conducted in the field conditions of Siberian Research Institute of Agriculture in Omsk in 2013-2014. Winter wheat is a crop of high fertility; winter wheat can reveal its biological crop yield capacity when it is genetically protected from abiotic and biotic stressors and appropriate growing conditions. Genetic control of this feature is mainly determined by over domination and complementary epistasis. Its lability results in the fact that being influenced by environmental conditions it can change genetic formulas (set of genes) of the stalk length. The genetic control system of changes in the parameter is controlled by dominant genes. It certifies that selection of unique genotypes becomes difficult due to the change of meteorological factors combination. The author highlights that selection on the basis of “stalk length” should begin in later generations of hybrids (F4 – F6), when most genotypes go into a homozygous state. The author suggests to consider Splav variety in the humid conditions and Minskaya variety in dry conditions as a short - stemming donor.
VETERINARY MEDICINE AND ANIMAL SCIENCE
The paper explores the peculiarities of arterial blood supply of Italian goose’s esophagus. The authors applied methods of general and fine-scale section and angiography for conducting the research. The researchers investigated five carcasses of geese. The authors found out that ascending and descending esophageal arteries and branches of esophageal and tracheobronchial artery are the sources of esophageal vascularization. The authors outline the areal segmentation of esophagus and extremely high vessel compliance with high compensation abilities. Additional links between ascending and descending esophageal arteries with arcs and anastomoses contribute to normalization of blood pressure inside the paries. Ascending and descending esophageal arteries are directed towards each other and anastomose with each other. Arteries root from them on the dorsal surface of esophagus and join esophagus at an acute or obtuse angles to the adventitia at the bone segment level. Ascending and descending esophageal arteries are the sources of vascularization of the primary and secondary parts of esophagus; abdominothoracic part receives blood from the branch rooting from esophageal and tracheobronchial artery. The authors highlight extremely high vessel flexibility with compensation abilitites, additional links between ascending and descending esophageal arteries with arcs and anastomoses contribute to normalization of arterial blood pressure inside the paries. The research contributes to detail classification of arteries branching peculiarities in Italian goose’s esophagus.
The author highlights the research results on exploring the scheme of application of enzyme probiotic Cellobacterine-T produced by Biotrof enterprise in St. Petersburg. This probiotic is a complex of cellulolytic and lactic acid bacteria isolated from rumen of ruminants and selected on the parameter of high ability to decompose cellulose. This allows to use the specimen in poultry ratio with high concentration of wheat, barley, sunflower protein meal and seed cake. Cellobacterine-T acts like a probiotic when it contributes to stable poultry digestion. The researchers offer to apply Cellobacterine-T dosed 1 kg/t for chickens aged 3 months and increase the dose on 50% - 1.5 kg/t when ovogenesis organs are being formed; at the peak of egg-laying capacity – 2 kg/t; at the final stage to use standard dose 1 kg/t. Feed accessibility and digestibility are high and this contributes to better feed conversion, reduces palatability on 8-140 g per each laying hen. Egg laying capacity of experimental hens which were fed with Cellobacterine-T dosed 2 kg/t for two months has reached 98% against 61, 66, 71% in the control group. Feeding laying pullets with Cellobacterine-T improves poultry evenness to the beginning of fertile period, which increases egg laying capacity on 8-12% and reduces feed costs on 5-7%. Cellobacterine-T increases average daily growth on 3-10% and feeding costs on growth on 9-15%. Cellobacterine-T increases application of sunflower protein meal in growth and finish ratios up to 20-30% regardless reducing livestock parameters.
The article revels the research results on exploring the influence of Holstein servicing bulls on morphological and functional udder parameters and milk productivity of Kholmogorskaya first-calf cows. The researchers used the method of analogues and arranged 6 groups of heifers from the moment of birth, taking into account the genotype, age and live weight. The authors observed the best measurements of udder and dugs in 1,3 and 5 groups of cows, exactly the daughters of Neapol 5791 bulls, Versal 79552467 and Lazurit 61968904. These cows had longer and wider udder with a depth of the forequarters equal to 19.3-19.6 cm, girth - 8.0-8.2 cm, high rate of breast (2.13-2.38 kg / min) and the greatest milk yields for 305 days of lactation (5131.7-5548.2 kg). First-calf cows of the 5thgroup dominated among the other groups. These cows were bred from Lazurit 61968904 bull and produced milk on 474.1 kg or 9.3 % more than average parameter among the groups (P<0.05). Higher milk yields were observed together with lower part of fat in milk 3.74%; this parameter is lower than the average one on 0.15%. The part of protein in milk (3.05%) was higher than the average parameter on 0.03% (P<0.05). The data obtained on morphological and functional parameters of udder and milk productivity of cows for the first lactation highlight that further improvement of Kholmogorskiy cattle requires involvement of Neapol 5791 bulls, Versal 79552467, Lazurit 61968904 that belong to three lines: UES Ideala 933122, Reflection of Sovering 198998 and Montvik Chiftein 95679.
РЫБНОЕ ХОЗЯЙСТВО
After constructing Hydro Power Station on the Ob in the area of Novosibirsk, the authors observed that the conditions for reproduction of sturgeons and whitefish were kept. Species and number of young fish in the dam basin was formed by means of young fish migration from the basin. The researchers observed pike perch larvae and bream larvae in the years when low level of water was observed. When high level of water was observed, the authors found the species located in the upper layers of the basin. Nerfling species dominated in the Ob gulfs near the dam. Due to these fish migrating from the reservoir of juveniles and pike-perch larvae from river spawning temporary communities of juveniles are created in the riverbed with the duration of existence from 14 to 33 days. Young fish communities with livability from 14 to 33 days are formed by means of young fish and pike perch migrating from the basin. The maximum number of larvae in the river (0.617-0.703 EQ/m)3 was observed in the 1990s at maximum fish yield in the river and basin. Bream and pike-perch made more than 90% of fish yield. The number of young fish was much higher and equal to 29.9 – 102.7 samples/ m3 in the coastal shallow waters in the area of the spawning grounds. Carp species were mostly observed. The duration of young fish communities livability in the coastal area was 4-5 days more in comparison with that in the basal places. In the last decade, the conditions for fish reproduction in the Ob of Novosibirsk area are getting worse. Lower migration of the young fish from the basin influences its quantitative and specific composition in the river. The authors revealed reducing of young fish in the Ob basin, especially pike perch which is the most valuable commercial species. Low part of young fish migrating from spawning areas is supposed to reduce livability due to lack of conditions for feeding on shallow waters where the larvae are absorbed by pumps and die in the basins of the water consumed.
