DescriptionThe modern cattle breeding in Russia is characterized by dynamic development, development of intensive technologies, increase in production, but at the same time, there are problems of increase in production of milk due to increase of dairy efficiency of cows at the most effective manifestation of the available level of their genetic potential. For the solution of this problem, i.e. for genetic improvement of dairy cattle, creation of new breeds, intra pedigree or zone types, more than 100 thousand of bulls with high genetics, and also 430 thousand heifers were delivered to Russia for the last 10 years. In this regard, the purpose of our researches was to study the level of genetic potential of dairy cows in breeding farms of "Nasha Rodina" of Gulkevichsky region, Vasyurinsky milk farm of Dinsky region, the Firm «Agrocomplex» of Vyselkovskiy region (Gazyrskoye enterprise), "Urozhay" of Kanevskoy region from 2000 to 2014, by using bulls of Golshtinsky breed. Researches have shown that in farms of the Krasnodar region producers with the high level of potential from 10791,0 kg to 12045 kg on milk were yield used on a breeding uterine livestock; from 4,22 to 4,40% of fat; from 3,32 to 3,49% of protein in milk. As a result the level of potential of daughters of bulls and cows in herds of farms was from 7774 to 9144 kg of milk; from 3,89 to 4,05% of fat; from 3,26 to 3,67% of protein in milk. However, genetic potential of new generation of animals is shown not completely. It is influenced by partial compliance of the created technological conditions of biology of animals, and indicators of breeding value of producers, with their prepatent indicators. Calculations of breeding value indexes of bulls – fathers of cows in the herd of "Urozhay" have shown that each bull has its breeding value, an ability to transfer the qualities to posterity. Bulls of Golshtinsky breed of red – motley color ( Pan 2037 and Tulup 78160689), by results of comparison of milk yields of daughters, mothers and contemporaries, had negative prepatent indexes of milk yield and milk protein content (according to F.F. Eysper and V. Sidorova). The data confirm the need of carrying out an obligatory index assessment of bulls before their use on the farm in order to avoid receiving descendants with low dairy efficiency

PROBABILITY OF ESTIMATION OF AMELIORATIVE CONDITION OF IRRIGATED FIELD WHEN USING BIOTECHNOLOGY
06.00.00 Agricultural sciences
DescriptionThe biotechnology (year - round utilization of livestock and spirit wastages) was developed for the protection of farmlands and water objects. Technology of processing of organic wastages by means of earthworms (vermicomposting) gives the chance to use wastages of livestock complexes, to make a sewage disposal at minimum energy consumption. In the field experiment which was made in the training farm called "Kuban" for the detailed studying of influence of the held events there were put the platforms. The technique of probability of estimation of ameliorative condition of an irrigated field is given in the article. The nonparametric statistical assessment of degree of soil compliance to the normative conditions is defined

DescriptionThe author has examined peculiarities of meat productivity of animals of the most common breeds: Charolais, Simmental, Aberdeen Angus, Hereford, Kuban type of Red Steppe. As a result of the slaughter carried out for younger group achieved 15 months age, the Charolais breed bulls exceeded peers of Kuban type on slaughter weight to 60.9 kg (20.9 %), Aberdeen Angus – 53.8 kg (18.5 %), Hereford and Simmental respectively – to 35.1 and 24.8 kg (8,5-12,0 %). By the age of 18 months their superiority increased respectively by 56.9; 57.5; 55.8 and 29.9 kg (16.8; 16.9; 16.5 and 8.82%). Halves of bodies of the Kuban breed (considering the specific type of boneless beef output) aged 15 months gave way to all the groups: Charolais and Angus – by 1.1- 1.5%, Simmental and Hereford – by 0.4-0.6%. The yield of premium beef exceeds the standards in all genotypes: Kuban – by 9.5%, beef breeds – by 11.2% (Charolais) and 19% (Simmental). The balance beetween dry matter and moisture is in the optimal range (0.43: 1-0,73: 1). At 15 months of age, in the number of dry matter, Charolais bulls outnumbered Aberdeen-Angus and Red steppe at 5.1-5.2%, Simmental and Hereford - on 3,0-4,9%. With age, in the meat of calves of beef breeds the level of fat increased, for example, in Hereford and Simmental 0.3-0.5%, Aberdeen Angus and Simmental – 0.7-0.8%. In the middle of a sample of ground beef of carcasses of the calves of Charolais breed at the age of 18 months it contained more protein than in the meat of the calves of Red steppe (1.2%, Hereford (1.1%), Angus (1.4%), Simmental (1,3%). All the meat of the carcasses of the calves of specialized beef breeds was of high quality and diet: one part of the protein had 0.59 parts of fat (Aberdeen Angus) and 0.45 parts (Hereford)

Description
Nigeria has the largest oil sands and bitumen resources in Africa and is one of the main leading countries in the world from the point of view of its significant potential heavy oil deposits. Research of geological and physicochemical properties confirmed that the Nigerian bitumen is an important energy source and an alternative source of hydrocarbon feedstock for the petrochemical industry. Nigeria imports black oil for the petrochemical industry and its heavy oil can act in place of this black oil. In addition, researchers have successfully established the possibility of producing electrical energy from this heavy oil. Tar sands and bitumen are able to help improve the economy of Nigeria

SCIENTIFIC AND METHODOLOGICAL ASPECTS OF TOBACCO SEEDS GROWING
06.00.00 Agricultural sciences
DescriptionNicotiana tabacum and rustica are facultative self-pollinated plants, therefore, because of pollination peculiarities, specific methods are applicable to growing seeds of this plants. Researches on mass, individual and family, recurrent methods of seeds selection for productivity and sowing properties are carried in the institute for revealing most efficient methods of getting seeds. Seeds growing system for Nicotiana tabacum and rustica is a part of general seeds growing system for all agricultural plants and consists of breeding, testing new sorts, mass reproduction of seeds with retained biological and productivity properties, seeds harvesting and controlling their sort and sowing properties. Primary growing of nicotiana tabacum and rustica seeds is carried by individual and family or recurrent selection and further testing of chosen plants, distinctive for this sort, on economically valuable and biological properties. Peculiarities of each zoned sort are kept by retaining its primary genome with constant selection of highly productive genotypes, specific for this sort. Well-organized seed growing system leads to sort potential revealing. Biotype composition of sort is obviously changing in a few years, so primary seeds growing system should be constantly improved

Description
Delinquents and criminals in the economy, actively apply modern tools of implementation of economic relations while using the so-called "gaps" and inadequacies in the law. Often, to prove intentional sequence of interrelated transactions between counterparties for public authorities authorized in the field of Economics is quite difficult. The main problem is the lack of information about the facts of economic life that took place in the economic system of the administrative-territorial education and beyond. On the other hand, economic actors have difficulty when choosing a contractor, the burden of control activities and the need of proving innocence. Implementation of measures to stimulate sectors of the economy faced a challenge of bringing the right information and the willingness of subjects to participate in their implementation. There are professional illiteracy and the lack of necessary information about the rules of participation in the stimulus package, as well as practices and examples of economic behavior. The authors propose the use of the resource of a uniform accounting system, allowing solving the task of eliminating the above difficulties. The article presents the procedure for its application in individual cases for the implementation of economic operations, implementation of control measures. We have also investigated the circumstances and conditions of its application
