DescriptionThe article contains data on results of calving and blood tests of heifers moved from the Astrakhan region in the Temryuk district of the Krasnodar region in the condition of early pregnancy. According to the accompanying documents, cell blood count, hemoglobin and biochemical parameters were consistent with species and age normal. Calving took place without complications and did not require delivery; received 36 of 36 calves from cows. The quality of the calves found to be satisfactory. On the 45th day of service period, clinical signs of impaired health status were present in 2 animals, however biochemical markers of liver disease, inflammation, and anemia was identified in 7 heifers. In the context of work on creation of livestock combined milk and meat productivity of inseminated heifers and heifers of the Simmental breed the Simmental semen (25 cows) and Aberdeen Angus (34 cows) breeds. Fruitfully inseminated 55 out of 60 animals; indicator of severity of calving was 8 % for Simmental cows. Calves of Simmental breed and Simmental-Aberdeen Angus cross-breeds meet the requirements for live weight at birth and the exterior. Farming on the formation of herds of milk and meat direction of productivity are found to be effective

THE RESULTS OF THE REFORM OF THE EDUCATION SYSTEM IN RUSSIA
DescriptionOne of the main tasks is the improvement of the education system, the quality of which depends on the level of economic development of the country. In Russia, for more than 10 years there has been a continuously reformed educational system. This is due to Russia's accession (in 2003) to the group of countries – participants of the Bologna Declaration, involving the convergence and harmonization of education systems in European countries with the aim of creating a unified educational space. The article describes the main positions that are subject to a quality assessment of education from foreign universities; we have also revealed the reasons for the low world rating of Russian universities. At present, the education system of the country should facilitate accelerated development of the economy of the state in the first place. This work reveals the shortcomings of the main reforms related to the implementation of CSE in secondary educational institutions, the bureaucratization of the higher education system that resulted in time reduction of contact of the work of students with teachers, and as a result – deterioration of quality of preparation of graduates. We have also revealed the causes of the current situation and the main directions that will contribute to the development of the education system in Russia. These areas are the development of: a strategic plan for the development of higher education; a training system worthy contingent of higher education institutions; an effective system of preparation of students and evaluation of the quality of their knowledge and labor potential; a system of training for scientificpedagogical personnel and improving their qualification; assessment criteria of effectiveness and ability of educational institutions to provide quality knowledge

RESULTS OF THE CHERRY BREEDING ON FRUIT QUALITY IN THE LOWER VOLGA REGION
DescriptionIn cherry breeding aimed to improve fruit quality, methods of intervarietal, interspecific and remote hybridization are often used. As a result of the conducted studies, new promising cherry varieties of different maturation period, developed in the conditions of the Lower Volga region by the method of remote ecologic-genetic hybridization using the best local varieties, were studied. The most effective crosses are those developed with use of high-quality cherry forms Zhukovskaya and Podbelskaya. According to the aggregate parameters of fruit quality (dry matter content, sugar-acid index), the following varieties were positively identified: Temnookrashennaya, Dubovochka, Lydia, Rozovaya, Lyubimitsa, Coloritnaya, Korneevskaya, Loznovskaya, Afina, Sharada, Lexema. The content of vitamin C - Temnookrashennaya, Lydia, Coloritnaya, Rozovaya, Lexema. Varieties Temnookrashennaya, Lydia, Coloritnaya, Rozovaya, Lexema are offered for use in the canning industry

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

Description
The article deals with the results of research of acoustic and magnetic field influence on conductivity and pH value of hydroponic solution. For carrying out researches in this area the hypothesis of possibility of nutrient solution influence on ions by means of an acoustic and magnetic field is set up. A laboratory scale plant was constructed for a pilot study of the hypothesis. The solution was moved in the tube passing through a ferrite ring with winding. Thus, the solution was exposed to the influence of acoustic and magnetic field. The object of research was hydroponic solution of (NH4)2SO4; (NH4)2HPO4; K2SO4; Ca(NO3)2; MgSO4 in water having adjusted concentration and acidity. The solution was taken from the tank of laboratory scale plant by means of the pump, passed through the working area of the acoustic and magnetic device, filter, and then was poured into the tank, from which the sample for pH level changing was taken. The pH value was measured at the temperature of 22С by using electronic pH-meter KL-009(1)A. For control of instrument readings acidity was tested by universal test-paper. The initial pH value of solution made 5. As a result of acoustic and magnetic treatment of solution pH value of hydroponic solution increased from 6 to 6.9. The results show the possibility of pH value correction by small energy input
