06.02.00 Veterinary and Husbandry
Description
In the article, there were shown the experimental researches describing the influence of parameters of electrical ozonization of the premises of egg storehouse at concentration of ozone in 20 mg/m3 on survival of following stimulants: S. aureus, S. choleraesuis, P. vulgaris, E. coli. There was determined that ozone has an ability to detain the growth of fungi on biological substrates as well as it slows down the process of mould appearance on egg shell surface even at 90% of relative moisture. The aim of scientific experiment is obtaining of regression models of influence of parameters of electrical ozonization on main sanitary-model microorganisms contaminating the shell of incubation eggs. To assess the effectiveness of ozonization there was adopted the parameter of survival for four main pathogenic microbiological test-objects which predominate on egg shells. The correlation and regression analysis of factors and determination of value of equation coefficients there were conducted using the program STATISTICA 6.1. The correlation analysis was made by the method of Pierson. Approximation was obtained by the method of polynomial. On the results of researches there was determined that the least survival of present test-bacteria at concentration of ozone in 20 mg/m3 is achieved at exposition 84 minutes. So, the rational time the electrical technological process of ozonization of egg storehouse of poultry factories presents the sum of obtained exposition and time of regulation

06.02.00 Veterinary and Husbandry
Description
In this work, the authors presented the results of monitoring urolithiasis in cats in Krasnodar in the period from 2016-2017. The authors established the sexual, age and breed predisposition of animals to this pathology; the seasonality of the disease was studied. An analysis of the actual data and reports of various authors made it possible to conclude that urolithiasis in cats is a polyethological disease. As a result of carried out hematological studies, the presence of an inflammatory process, which was manifested by lymphocytopenia, an insignificant increase in neutrophils and monocytes, as well as hematocrit, was ascertained. A laboratory analysis of urine showed that urine, as a rule, is turbid with an admixture of blood and sand, precipitating rapidly. The authors found an increase in the volume of urine in sick animals due to the inability to remove it, the specific gravity fluctuated within the limits of 1.015-1.020; pH = 7.5-8. With microscopy of the urine sediment, both unorganized and organized sediments were detected. The ultrasound examination of the bladder showed the presence in its cavity echo-positive particles in a suspended state, as well as sections of the desquamated mucosa

ASSESSMENT OF YOUNG PIGS ON THEIR OWN PRODUCTIVITY AND QUALITY OF SPERM
06.02.00 Veterinary and Husbandry
Description
A comprehensive assessment was made of the own productivity of repair pigs and the quality of sperm production of boars of different breeds. Imported boars and mumps had thin bacon 13-15 mm, high early ripeness 145-153 days and a depth of "muscular eye" 53-53.9 mm, indicating an increase in the content of lean meat in the carcass. However, the length of the trunk of the animals was 120 cm, which corresponds to the first class of the instructions for bonitation. There was a significant difference in the growth rate of repair young (about 300 g), which indicates the individual characteristics of animals and the possibility of selecting the best animals for reproduction of the herd. Assessment of pigs by phenotype is an important element of breeding work on complexes. It is established that the quality of sperm production is affected both by the breed and the season of the year: the volume of ejaculate and the concentration of spermatozoa in all breeds are greatest in the autumn-winter period. Boars Maxgro were distinguished by an increased volume of ejaculate, but a low concentration of sperm compared to a large white breed and landrace. During the year, the greatest fluctuations in sperm concentration in large white breed boars were observed ± 133 million / ml, the smallest - Landrace ± 29 million / ml, which contributes to the uniform production of semen doses for insemination

COMPARATIVE EVALUATION OF CANNED AND NATURAL FOOD IN THE DIET OF PREGNANT AND LACTATING DOGS
06.02.00 Veterinary and Husbandry
Description
The article provides evidence of the high social value of dogs as the most common among pets. We present the results of determining the main causes of illness in dogs and the role of nutrition in the formation of this indicator: the share of diseases of the digestive system and various metabolic diseases accounted for more than 70 % of the total of substantiated cases to the clinic. We have estimated chemical composition of feed premium, industrial production, assessed according to the standards of the National research Council (NRC) for dogs of small breeds in the period of pregnancy and nursing puppies. We have established the feed requirements of pregnant and lactating bitches (Yorkshire Terrier) for key nutrients and bioactive substances. Recipe is made up and we manufactured food standards NRC from natural ingredients; conducted a scientific experiment to assess the impact of both feed on milk productivity indices of mothers and indicators of growing puppies (body weight at birth, weight gain). We have convincingly demonstrated the advantage of using natural food as from a physiological and economic perspective, as it is accompanied by a marked reduction in the cost of the dog and of the cost of the puppies

INTERIOR FEATURES OF THE REPAIR YOUNG OF HOLSTEIN BREED
06.02.00 Veterinary and Husbandry
Description
The results of a comparative study of the experimental groups of Holstein animals belonging to the Vis Bey Eidial line are given: four groups of repair calves and four groups of gobies. Their hematological indices were studied at higher daily rates of milk drinking and early training of experimental animals to plant feeds with a probiotic supplement of cellobacterins in the milk period. The difference between the groups was the technology of their cultivation: I-control group - up to 6 months of the age was grown according to the traditional technology adopted in the farm: 200 kg of milk (for 50 days) and 400 kg of return (from 50 to 110 days), and concentrated feeds consisting of pre-fodder (50%) and corn (50%), the same calves received experimental calves; II-test group - up to 6 months increased norm of milk drinking (for 25 days) - 200 kg and 400 kg of return (from 25 to 60 days); III-test group - up to 6 months the increased norm of drinking milk (for 50 days) - 450 kg and return (from 50 to 110 days): heifers - 600, bulls -800kg; IV-test group - up to 6 months an increased rate of milk drinking (for 60 days) - 450 kg and return (from 60 to 120 days): heifers - 600, bulls -800 kg. The calves of all experimental groups were fed a probiotic preparation of cellobacterin in an amount of 3 g for each animal up to 18 months of age. When the experimental animals reach 12-, 15-, 18-months age, hematologic examinations were carried out. It has been established that with the age of experimental animals, metabolic processes are intensified, the change of which was influenced by the use of different norms of drinking milk during the milking period, using a probiotic

SYNCHRONIZATION OF THE HATCHING AT THE ARTIFICIAL INCUBATION
06.02.00 Veterinary and Husbandry
Description
The embryo passes a number of the stages caused by high-quality structural changes in development and following them growth periods. The periods of change of development for the periods of growth are critical and are most sensitive to influence of external factors. The developed differentiated mode provides sharp temperature increase of incubation in the critical periods of development of an embryo. High temperature at separate stages of an incubation has displaced metabolic processes of the developing embryo towards lipidic exchange, at the same time the cholesterol indicator in blood of skilled chickens has grown more than twice, and level alkaline phosphatase by 2,5 times. Synchronization of the hatching was reached due to reduction of the periods embryonic and output on about 10-12 of hours. Operating an embryogenesis in the period of incubation there is an opportunity to influence the level of productional processes of chickens during the post-embryonic period, average daily gains of live weight at cultivation of broilers increase on average by 5-7%

PERSPECTIVE OF USING KRASNOSTOPS OF THE ANAPA STATION SELECTION IN THE WINE-MAKING
Description
Currently, more and more popular in the world are indigenous grape varieties. Now in Russia and abroad there is a growing interest in Krasnostops - a high quality indigenous red grape varieties of technical direction. The object of research was the red technical grape variety called Krasnostop Anapa and Krasnostop AZOS, grown in Anapa ampelocalamus and wine from them. As a control, we used two classic grape varieties of varying degrees of saturation in color and extract content of the wines of Cabernet Sauvignon and Saperavi. The article presents the materials of years of research – agrobiological, technological and economic indicators of technical grades of grapes of selection of the Anapa station – Krasnostop Anapa and Krasnostop AZOS. The amount of anthocyanins in wine from Anapa Krasnostops has superior data for these components in the control options. The mass concentration of phenolic substances and their monomer forms in wine materials of grape varieties Krasnostop AZOS and Krasnostop Anapsky is higher than in the quality control of red wines-Cabernet Sauvignon, which indicates a high accumulation of phenolic substances in new grape varieties. In the years of the study of Krasnostop AZOS and Krasnostop Anapsky on organoleptic properties of wine has received good performance - and of 8.78 8.73 points. The brands of wines developed on their basis will fill up a number of high-quality table and liqueur red wines in the Russian market. These grapes have high potential and great prospects in the light of the global trend of their use in winemaking. All this allows to recommend these grades for wide introduction into production in the southern wine-growing regions of Russia
