OPTIMIZATION OF GRAPE GROWING TECHNOLOGY BASED ON USING THE METHOD OF YIELD PROGNOSIS
06.00.00 Agricultural sciences
Description
The article highlights the questions of preliminary determination of the yield of vineyards, grape harvest prediction method to determine the optimal length of fruit cutting of shoots and load bushes wintering eyes, kidneys examined productivity index wintering buds (CP), which shows how many inflorescences have an average for each left eye escape when cutting to length, including the dead. It was found that the yield of grapes has a great influence the degree of differentiation of inflorescence of rudiments in the central buds overwintering buds. From the moment of laying the harvest of grapes in hibernating little eyes in the form of embryonic inflorescences until commercial harvest takes two growing seasons. During this period the generative organs of grape plants are affected by many factors of the environment. Heterogeneity was found of buds along the length of one-year matured shoots. It is expressed in the fact that many grape varieties fruitfulness buds at the base of the shoot are much lower compared with upstream eyes. A certain death of wintering buds (primarily, the main kidney) at the end of the growing season, before the autumn frosts. The main reason for the death of buds during the growing season - from defeat fungal diseases. Taking into account the percentage of deaths of buds proposed a new exponent forming embryonic kidney main inflorescence - productivity index of buds by the ratio of embryonic stems to the number of buds, including the dead. Thus, annual forecasting of grape harvest next year to cutting the bushes by the proposed method makes it possible to scientifically establish the optimal cut length of shoots and fruit load on the bush eyes. This helps to realize directly the potential of each variety and vineyard site and get maximum yields even in years with low fruit tab formations

OPTIMIZING CONDITIONS FOR INTRODUCTION OF RASPBERRY AND BLACKBERRY INTO CULTIVATION IN VITRO
06.00.00 Agricultural sciences
Description
We have studied survival and regeneration rate of raspberries and blackberries buds when introducing into cultivation in vitro during October. The rate was significantly higher for buds taken in October than that for ones taken in February. At the first stage of micropropagation, for the most of studied varieties of raspberries, cultivation on nutrient medium contained BAP (0.5 mg/l) and GA (0.2 mg/l) was most successful; for blackberries, increasing concentration of hormones (BAP to 1.0 mg/l and GA to 0.5 mg/l) was better

THE EXPERIENCE OF CREATING A POPULATION OF MEAT-WOOL SHEEP
06.00.00 Agricultural sciences
Description
The study of the productive qualities of crossbred offspring from different breeding combinations and identifying the most effective ones providing the maximum increase in the production of high quality lamb while reducing its cost is an important problem and is essential for further development of methods of creating a new type of precocious meat and wool sheep. In the Rostov region in the result of the establishment of populations of meat-wool sheep there are several groups of animals with different characteristics and hereditary inclinations. As the base of the work there is a method of mating and breeding of sheep of the desired type. The article presents the results of one of the fragments of a large complex work in which the possibility of using three-pedigree hybrids, created with the involvement of potential salskaya, edilbaevskaya and intense meat-wool breed, which is severokavkazskaya, to improve productive quality in the breeding of sheep. We have evaluated productivity and biological features of hybrids and proved the economic efficiency of their use in the production of mutton. We have given the results of the control slaughter and assessment of qualitative indicators of the meat of young sheep. The set of indicators characterizing meat productivity and meat quality revealed that the superiority of the studied indicators remained for two - and three-bred cross cattle. Hybrids have a higher rate of growth and quality parameters of meat productivity. These options are simple and complex industrial crossing are promising and can be implemented and used on the farms of the zone of breeding Merino sheep. Thus, the use of crossbreeding gives an opportunity to convert a flock of sheep in the desired direction quickly. At the same time, three-pedigree hybrids better combine the valuable qualities of the used species

Description
We developed an effective technology of reproduction in meat cattle breeding, which allows rational use of the bulls-producers, to obtain a high output calves (85-95%), to organize the accuracy of the account of the origin of young animals, to improve the level of selection-breeding work on the improvement of productive and breeding qualities of animals and create in a shorter time highly productive herds of meat cattle

PECULIARITIES OF NON-INFECTIONAL ARTHRITIS IN GROWING POULTRY IN AN INDUSTRIAL ENVIRONMENT
06.00.00 Agricultural sciences
Description
The problem of industrial poultry farming is the emergence of a growing birds’ arthritis. Inflamed joints are usually seen in poultry and accompanied by the inability to take food and water. The most characteristic of this problem in broiler chickens, young chickens of egg cross, i.e. birds of a short period of use. This is the reason for their rejection of the herd. Culling chickens are 10%, which furthermore reduces the total amount of livestock and leads to a reduction in the cost-effectiveness of growing birds. The analysis of our data gives a reason to believe that the main reason for culling poultry is acute inflammation of the joints or arthri-tis. According to the authors to ensure optimal rearing program, which should include the prevention of premature retirement of birds not only due to infectious diseases, but also the prevention of metabolic disorders and the exclusion of factors that could cause disruption of immunological reactivity. Currently, this program needs to be improved, which is particularly important in relation to vaccine pre-vention
