Розглянуто ґенезу та метаморфози поняттєвого поля блогінгу як специфічного явища культурної діяльності та комунікації в соціумі. З’ясовано, що одним із найбільш обговорюваних феноменів мережевої культури є блог. Проаналізовано соціокомунікаційні, соціологічні, філологічні, політологічні, культурологічні, філософські розвідки вчених, присвячені блогінгу; простудійовано ґенезу цього специфічного явища культурної діяльності.
Доведено, що дослідниками пропонуються досить різні визначення поняття «блог» як у межах журналістики, комунікології та лінгвістики, так і в міждисциплінарному контексті. Однозначна думка про те, через яку дефініцію найбільш доцільно витлумачувати сучасний блог, у сучасній науці відсутня.

Published: February 2021

One of the most dangerous ectoparasites that infects poultry is the red chicken mite (Dermanyssus gallinae), which causes dermanisiosis, which is widespread in many countries around the world, including all regions of Ukraine. The article shows the basic biological and ecological characteristics of the red chicken mite Dermanyssus gallinae.

gallinae is a carrier of infectious and viral diseases including: Salmonella gallinarum, Salmonella enteritidis, Chlamydia spp., Borrelia anserine rhusiopathiae, Listeria monocytogenes, Coxiella burnetii, Escherichia coli, Staphylococcus sрр., Marek's disease, Newcastle disease and other dangerous poultry diseases.
gallinae causes significant economic damage due to reduced egg productivity, quality of poultry products and increased culling and death of poultry due to depletion.

The article analyzes the market of insecticides registered in Ukraine for the control of red mites. The effectiveness of preventive and curative measures in the battle against D. gallinae largely depends on the method and desacarization medication. Among the existing methods of control against D. gallinae remains chemical because synthetic insecticides have a wide range of action, while destroying a number of pests from different groups at different stages of development.
To prevent outbreaks and spread of mites in poultry farms, it is necessary to systematically implement a set of organizational and veterinary measures, taking into account the biological characteristics of the development of existing ectoparasites in the farm and technological cycles of poultry.

Published: February 2021

Significant economic losses to poultry farms are caused by infectious, especially viral diseases, including infectious avian encephalomyelitis (IAE). A possible threat to the profitability of the poultry industry in Ukraine at present is the epizootic disadvantage of poultry infectious encephalomyelitis. Economic losses from IAE include losses from increased poultry death, reduced productivity, hatchability of chickens, additional costs for disease prevention and elimination. Quick and effective diagnosis of the disease, in this case, makes it possible to predict the development of the epizootic process, assess possible economic losses, timely and correctly develop a plan of treatment and prevention measures. Permanent immunity is formed after the disease (again, the poultry is usually not sick), as well as during vaccination. The only effective method of IAE prevention is preventive vaccination of parent flocks and laying hens with live vaccine before laying eggs (in immune herds of laying hens, the virus is not transmitted vertically). In Ukraine, live - mono and combined vaccines have been registered for the specific prevention of IAE, including: mono- vaccines - 5 (45.4 %) and combined - 6 (54.6 %).
During selective serological monitoring of blood sera of poultry eggs from some poultry farms of Ukraine for the presence of antibodies to the IAE virus of poultry, different levels of average titers were found. In total, the blood sera of laying hens from 34 batches from 15 poultry farms were tested for the presence of medium antibodies to the IAE virus. Medium antibody titers in poultry that were vaccinated with live IEM vaccines once at the age of 62-70 days ranged from 999 to 12785. Below the baseline, medium titers were found in 2 batches, namely among birds aged 13 and 22 weeks.
When determining the effectiveness of the vaccine VIR 110, Biovak (Israel), which was used on 29 batches of laying hens, it was found that the average titers to IAE virus ranged from 222 to 10520. Moreover, the average titers of antibodies to IAE were below baseline (from 5000 - 12,000) among birds of 3 batches at 13, 15, and 45 weeks of age, which is 10.3 %. The effectiveness of the vaccine VIR 110 (Biovac) against IAE was 89,7 %. Continuous serological monitoring is necessary to monitor the effectiveness of IAE vaccinations and the epizootic welfare of poultry.

The article presents the results of determination of acute and subacute toxicity of the drug "Chloracil", which was made on the basis of chlortetracycline hydrochloride. In result of the conducted researches, it was found out, that a single intragastric administration of the drug according to SOU 85.2-37-736: 2011 belongs to the 4th class of toxicity - low-toxic substances.
In determining the toxicity of the drug by the long-term use, it was found out, that the use of Chloracil in therapeutic and in 10 times higher than the therapeutic doses did not cause death of white rats. The animals of the experimental groups were active, ate well food , and the general condition of the animals did not differ from the condition of the animals of the control group, but there was a tendency to decrease the weights of liver, spleen, heart, lungs, thymus and kidneys on the background of an increase of body weight by 3.4 and 7.3% (p <0.05), compared to the values of the control group. Therefore, the use of the tested drug in above doses for 14 days does not significantly affect on the functional state of the internal organs of experimental animals.
The study of the effect of the drug on the hematological parameters of blood by long-term use showed that in therapeutic and in 10-time higher therapeutic doses observed a tendency to decrease the hemoglobin concentration, amount of erythrocytes, leukocytes, hematocrit value, on the background of a slight an increase of platelet. In determining the value of erythrocyte indices, it was noted that the use of the drug "Chloracil" in animals of I and II experiments did not cause significant changes in mean corpuscular hemoglobin (MCH). Mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC) were at the level of the control group.
When studying the effect of the drug on the biochemical parameters of blood serum in animals of I and II experimental groups, there was a tendency to decrease the level of creatinine, activity of AST, ALT and LP activity on the background of a slight an increase of total protein content.
Analysis of the obtained data shows that the use of the drug "Chloracil" to white rats for 14 days in therapeutic and in 10-time higher therapeutic doses caused a slight decrease in the weight of internal organs, hematological and biochemical parameters of blood, which that in turn did not significantly effect on the general condition of animals.

The activity of malate-aspartate shuttle enzymes in the reproductive organs and epididimal sperm of bulls and boars was studied.
The research was conducted on bulls of the Ukrainian black-spotted dairy breed (n = 5; aged 14 - 16 months) and boars of the Great White breed (n = 3; aged 10 - 12 months). After slaughter, the testes and testicular appendages were removed and the spermatozoa were washed with 0.9% sodium chloride solution. Testicular and epididimal tissues were homogenized and centrifuged. Aspartate aminotransferase (AST), malate dehydrogenase (MDG) and protein concentration were determined in the supernatant and epididimal sperm.
The specie and tissue specificity of aspartate aminotransferase and malate dehydrogenase activity have been established. In particular, in bulls, the activity of AST in the tissues of the testis, head and body of the epididymis of bulls is almost the same (116.5 - 118.3 nmol/min×mg of protein) and on 18.5 - 19.7% (р<0,05) higher in the tail of the appendix. In this case, MDG activity in the reproductive organs shows wavy changes: in the testicular tissue is high (1.96 ± 0.15 nmol / min × mg of protein), and in the epididymis: in the head is reduced (3.5 times ; p <0,001), increased in the body (p <0,05) and decreased again in the tail. In the sperm of bulls, the activity of AST from the head of the appendix - 69.3 ± 8.06 nmol / min × mg of protein, from the body - increased (p <0.05) and again (p <0.001) decreased from the tail of the appendix. MDG activity in sperm from the head of the epididymis was 0.50 ± 0.04 nmol/min×mg of protein, lower by 38.0% (p <0.05) from the body and 50.0% (p <0.001) higher in the tail.
In boars, the activity of AST in testicular tissue - 20.3 ± 5.22 nmol / min × mg of protein and higher in the appendix: 45.6% - in the head, 59.0% - in the body and 64.0 % - in the tail. Similarly, the activity of MDG in testicular tissue was 0.22 ± 0.02 nmol / min × mg of protein, increases by 40.6% in the head and remained at the same level in the body of the appendix, and in the tail tissue above 2, 5 - 2.7 times (p <0.001). In bovine germ cells, the activity of AST and MDG from the body of the appendix was, respectively, 102.3 ± 6.1 and 13.20 ± 0.15 nmol / min × mg of protein, lowered twice (p <0,001) and 10.7 % in the head and more than four times (p <0,001) and 61,2% (p <0,001) in the tail of the appendix.

Urocystitis, as a nosological unit, explains the inflammatory process of acute or chronic nature in the bladder and urethra. This disease is quite common among cats kept indoors.
Early diagnosis of urocystitis, in particular differential, is difficult and should be comprehensive, and include: collection of medical history, clinical examination of a sick animal, laboratory examination of urine, ultrasound (ultrasound diagnosis) of the urinary system. The article presents a clinical case from the veterinary practice of diagnosing urocystitis in a domestic cat. The research was conducted according to generally accepted methods, using special equipment. Catheterization of the bladder was performed to select urine. Changes in the clinical condition characterized by oppression of the animal, pale mucous membranes, anorexia, dysuria, forced posture of the animal, hematuria. Urination in a sick animal is frequent and difficult, or no, hyperemia of the penis, there is pain on palpation of the bladder. In the urine of animals with urocystitis revealed a decrease in relative density to 1.017 g / m3 and an increase in pH to 6.6. Epithelial cells of the bladder, leukocytes (up to 10 cells in the field of view) and a significant number of erythrocytes were registered in the sediment. Biochemical examination diagnosed elevated urea content, which corresponded to 18.8 mmol / l and creatinine - 158.1 μmol / l, respectively. The results of ultrasonographic examination of the urinary system in a sick animal are highlighted. Changes in the size of the bladder due to significant filling of urine, diffuse thickening of its walls and the presence of sediment in the form of flakes, which is easily moved and visualized sharply echopositively.
Diagnostic tests and their analysis confirmed the diagnosis of urocystitis in a domestic cat.

Authors: Nahorna L. V. , Proskurinа I. V. 
Published: February 2021

The article presents data on the establishment of the possibility of permanent ectoparasites of cattle to transmit pathogens of infectious diseases. Temporary and permanent ectoparasites are a constant threat in cattle farms. Permanent ectoparasites of ruminants can be carriers and reserves of pathogens of infectious diseases, both viral and bacterial etiology. They create additional risks and dangers that prevent the maximum realization of the genetic potential of productive animals. The work was performed during 2019-2020 on the basis of livestock farms of Sumy and Poltava regions, parasitological and bacteriological departments of the Sumy regional state laboratory of the State Service of Ukraine for Food Safety and Consumer Protection. In the conditions of cattle farms, selective parasitological studies of animals for infection with ectoparasites were performed. Detected ectoparasites were placed in test tubes with 70 % ethyl alcohol, in order to further their species identification.
To study the contamination of ectoparasites with microorganisms, they were made of saline in a ratio of 1:10. Then the resulting suspension was sown on nutrient media (dense and liquid) to isolate: Listeria spp., Salmonella spp., Streptococcus spp., Enterobacter spp. and Staphylococcus spp. In the course of selective parasitological studies of cattle of different ages in the farms of Sumy and Poltava regions, we found different intensities of animal invasion by hair follicles Bovicola bovis. Pathogenic properties of microorganisms were established by bioassay on guinea pigs and white mice. Pathogenic properties of bacteria of the genus Listeria spp. checked by conjunctival and dermo-necrotic tests on guinea pigs. During the three days of observation, redness was noted at the site of intradermal injection, with a marked increase in local temperature. Conjunctival hyperemia and eye discharge have also been reported.
To determine the pathogenicity of E. coli, white mice were infected intraperitoneally. The death of animals was recorded on the third day, indicating the pathogenicity of the isolated E. coli.
In a series of microbiological studies, it was found that the hair follicles of Bovicola bovis are carriers of pathogenic coccal microflora: S. aureus, E. coli and bacteria of the genus Listeria spp.

Authors: Ostapiv R. D. , Tkachenko V. І. 
Published: February 2021

The aim of this work was to investigate the effect of pH on the short-term stability of both individual water-soluble vitamins and their mixtures, thus characterizing the robustness of the method in relation to the pH of the solvent as one of the validation method parameters. Determination of vitamin concentration was performed by liquid chromatographic method immediately after their dissolution, as well as after exposure for 1, 2 and 3 hours at a temperature of 20ºC. The analysis was performed on a Waters liquid chromatograph equipped with an Alliance 2690 separation module with a PAD 996 diode array detector. Sample separation conditions: Luna Omega Polar C18 250 × 4.6 mm, 5 μm chromatographic column. Mobile phase: a mixture of acetonitrile with 0.05 M phosphate buffer solution, pH 3.0. For the separation of thiamine hydrochloride, nicotinamide, pyridoxine hydrochloride and ascorbic acid (vitamin group I), the ratio of components was 3:97, for the separation of ascorbic acid, riboflavin and cyanocobalamin (vitamin group II) - 15:85. The injection volume was 0.01 ml, the mobile phase flow rate was 1.0 ml/min, the column temperature was 25ºC, and the separation time was 10 minutes. The detection wavelength is 265 nm.
It was found that the decrease in the concentration of vitamins B1, B2, B6, B12 and nicotinamide in mixtures with ascorbic acid was within 10% at all pH values except 9.0. When buffer with this pH was used, the concentration of vitamin B1 decreased by 38 % in mixtures with vitamins B6, C and nicotinamide. Vitamin C was the most sensitive to pH. Thus, the greatest decrease in the concentration of ascorbic acid was recorded with the use of phosphate buffer with pH 5.0 and 7.0, both in group I vitamins and when vitamin C was present in solution without other vitamins. At pH 9.0, the concentration of ascorbic acid decreased in the range of 50-80 %. Ascorbic acid was stable when solvent with a pH of 3.0 was used. This solvent is proposed to be used for further validation of methods for determining water-soluble vitamins in premixes and feed additives.

Published: February 2021

The article presents a literature review on the need to balance feed for farm animals and poultry on the content of complete protein, which contains a complete set of essential and essential amino acids, the characteristics of feed materials of animal origin in relation to its protein value.
The section "Materials and methods" presents methods for determining: crude protein by the Kjeldahl method, digestible protein with 0,2 % pepsin, and the coefficient of digestibility, and the principles of testing, as well as characteristics of methods for determining the content of essential and non-essential amino acids. incl. sulfur-containing, using the system of capillary electrophoresis "Kapel-105M".
As a result of the conducted researches it is established that in terms of protein value (digestible protein and digestibility coefficient) feather flour is the least valuable, it is also poor in lysine, methionine, tryptophan and histidine, compared to other types of raw materials, despite hydrolysis and high heat treatment. Meat and bone meal are also less valuable in terms of digestible protein and essential amino acids. The best indicators of protein value were observed in dry blood plasma in terms of digestible protein content and digestibility coefficient, which is 89.9%, which indicates its good digestibility by animals and poultry.
In terms of digestible protein, essential amino acids and digestibility, meat, blood meal and dry blood plasma are the most valuable. Due to this, these products are effective in feeding for protein synthesis of livestock and poultry products.

The article presents data on the effectiveness of the new complex antiparasitic drug «Animal VetLine DeVorm plus anthelmintic drug for dogs and cats (suspension)» in comparison with the reference drugs «Drontal@ plus with meat taste» and «Drontal@ for cats» in use for therapeutic and prophylactic purposes in helminthiasis of dogs and cats of different breeds.
According to the results of helminthocoprological studies of feces, it was found that on the 7th day after the use of the experimental drug «Animal VetLine DeVorm plus anthelmintic for dogs and cats (suspension)» in one dog and one puppy (from 6 animals) a slight invasion (intensity of invasion of the pathogen Toxocara canis was 1–2 eggs in 1 g of feces) was observed, ie during this invasion the studied drug «Animal VetLine DeVorm plus anthelmintic for dogs and cats (suspension)» on the 7th day after application showed 83.3 % efficiency. However, the experimental animals had no invasion in the helminthocoprologic studies of the pathogen Toxocara canis on 14th day after treatment with this drug. In comparison, animals treated with reference drugs of endoparasitic pathogens on the 7th and 14th day of the study was not detected.
It should be noted that in cats on the 7th day after treatment, according to helminthocoprological studies, nematode pathogens were not detected.
The extensitivity of the experimental drug and reference drugs in field (production) trials for nematodes (Toxocara canis, Toxascaris leonina, Uncinaria stenocephala, Trichuris vulpis ) of puppies, dogs and cats was 100 %.
It was found that the tolerability of the antiparasitic drug by animals was good, it did not change the clinical signs and did not cause toxic effects. The drug has shown high extensibility in endoparasitic diseases of dogs and cats when used individually for therapeutic and prophylactic purposes and can be recommended for use in the practice of veterinary medicine.
