EXPERIMENTAL RESEARCHES OF OZONE INFLUENCE ON SURVIVAL OF PATHOGENIC MICROORGANISMS CONTAMINATING INCUBATING EGG SHELL

abstract 1351801009 issue 135 pp. 92 – 112 31.01.2018 ru 64
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

ANALYSIS OF MANIFESTATIONS OF UROLITHIASIS IN CATS

abstract 1351801013 issue 135 pp. 147 – 157 31.01.2018 ru 95
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

abstract 1351801028 issue 135 pp. 200 – 207 31.01.2018 ru 67
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

abstract 1351801029 issue 135 pp. 208 – 222 31.01.2018 ru 65
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

abstract 1351801030 issue 135 pp. 223 – 237 31.01.2018 ru 68
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

abstract 1351801032 issue 135 pp. 238 – 253 31.01.2018 ru 73
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%

THE SPREAD OF COLIBACTERIOSIS OF PIGS IN THE KRASNODAR REGION

abstract 1361802029 issue 136 pp. 179 – 188 28.02.2018 ru 68
The article presents data on the prevalence of colibacillosis of pigs in farms of the Krasnodar region in the period 2010-2016. Colibacillosis is widespread in pig farms of the Krasnodar region. In different years, it was recorded at 32.6 - 55.6% of bacterial infectious diseases of pigs. And only in 2013-2014, in farms of the region colibacillosis was not registered. Among the bacterial pathology, colibacillosis in pigs in the farms of the Krasnodar region is in the first place after staphyloccocus (3 - 15 %), streptoccocus (2-13,7 %), and diseases caused by conditionally pathogenic microflora (17,9-20 %). In the Krasnodar region, we annually allocate different serotypes of E. Coli that vary depending on areas and farms, however, regularly in pigs in the Krasnodar region there are the following serotypes: A8, О20, О119, О26, О86 in Bryukhovetskiy, Dinskoy, Kalininskiy, Korenovskiy, Kurganinskiy, Kushchevskaiy, Labinskiy regions of the Krasnodar territory. According to the reports of outbreaks, colibacillosis in pigs for several years were recorded in the Central, Korenovskiy, Kushchevskaya, Labinskiy, Primorsko-Akhtarskiy, Seversky, Slavyanskiy, Tbilisskiy, Timashevskiy, Ust-Labinskiy districts of the Krasnodar region and in the city of Krasnodar. After 2013-2014, after the total absence of the disease in the region, there were reported outbreaks in 2015 in some farms in the Timashevskiy district, and in 2016 – in Kurganinskiy

PREVENTION OF VIOLATIONS OF METABOLISM IN FRESH COWS

abstract 1361802030 issue 136 pp. 189 – 200 28.02.2018 ru 94
The main diseases of lactating cows occur in the first two months of lactation, i.e. during the production peak of productivity. They are caused by the changes in metabolism during the transition period, which are not supported by adequate changes in the organization of feeding, or rather sufficient to ensure cows with nutrients, which causes a number of closely related diseases. To allocate any of them is not possible, as their manifestation depends on a number of reasons, and depending on situation may prevail one or the other. Among the most common diseases, there are ketosis, milk fever (paresis of maternity), dysplasia of the abomasum, acidosis, mastitis, endometritis, laminitis and leukemia. These diseases cause the greatest problems in herds with high productivity, and are caused by changes in metabolism in cows in the transition period and the inability to properly feed the animals at this time. To identify the causes of these diseases we do not need to study each of them individually - it is enough to deal with the peculiarities of metabolism. This period includes the month before calving and the first or second month of lactation, but the most important are 3 weeks before calving and 3 weeks later. In order to prevent metabolic disorders there were developed and tested feed for feeding cows before calving and immediately after calving. Their effect was studied on milk production and health status

BIOLOGICAL PECULIARITIES OF GROWTH AND DEVELOPMENT OF GOLSHTINSKY YOUTH OF AUSTRALIAN SELECTION

abstract 1361802031 issue 136 pp. 201 – 214 28.02.2018 ru 56
The article presents results of a comparative study of the experimental groups of Holstein animals belonging to the Reflection Sovering line: four groups of repair calves and four groups of bull-calves. The peculiarities of their growth and development were studied at higher daily rates of drinking milk and early training of experimental animals to plant feeds with a probiotic supplement of cellobacterins in the milk period. The technology of growing the animals of the experimental groups had differences: I-control group - up to 6 months of age was grown according to the traditional technology for farming: 200 kg of milk (for 50 days) and 400 kg of return (from 50 to 110 days), concentrated feeds consisted of starter feed (50%) and (50%) maize, the same amount of concentrated feed and the same composition was obtained by calves from experimental groups; II-test group - up to 6 months of age received an increased amount of milk (for 25 days) - 200 kg and 400 kg of return (from 25 to 60 days); animals of the III-rd experimental group - up to 6-month-old age received an increased rate of milk drinking (for 50 days) - 450 kg and return (from 50 to 110 days): heifers - 600, bulls -800kg. Animals of the IV-experimental group-up to 6 months of agereceived an increased rate of milking (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. The live weight changed significantly depending on the age and the level of feeding of the experimental animals. The use in the feeding of calves of experimental groups of increased daily average milk yields and the addition of a probiotic to cellobacterin in the diet positively influenced the growth and development of experimental young animals, promoted a more intensive increase in live weight

CHARACTERISTICS OF HELMINTH INFECTIONS OF AMERICAN MINK (MUSTELA VISON), RACCOON (PROCYON LOTOR) AND WOLF (CANIS LUPUS) ON THE TERRITORY THE NORTH-WESTERN CAUCASUS

abstract 1361802032 issue 136 pp. 215 – 225 28.02.2018 ru 59
This article is devoted to the study of the species structure of helminths of the American mink, raccoon and wolf, conducted from 2006 to 2017. The study was subjected to 69 corpses of American mink - 30 of reed-bed, 22 flat, 17 of the Piedmont; 42 dead raccoon to 21 of the foothill and mountain; 24 corpse of the wolf - 8 from overflow land, foothill and mountain landscape-geographical zones of the Northwest Caucasus. The analysis of the results of the study showed that the determining factor in the formation of helminthocenoses of American mink, raccoon and wolf is the species structure of trophic-epizootic chains, the links of which are these predators, as well as species that act as intermediate, additional and reservoir hosts. Feature of helminthiases in carnivorous mammals is determined by a group of fodder. A dynamic increase in the number of species in the structure of helminthocenoses of American mink, raccoon and wolf was established, which is due to the anthropogenic transformation of natural ecosystems, violation of historical biotic relationships, including in the "parasite-host" system. The analyzed species of wild carnivores are involved in the support and formation of natural foci of such hazardous parasites as metros, Alaris, pseudamphistomum, mesocestoides, echinococcosis, trichinosis, dirofilariosis
