A STUDY OF BIOCHEMICAL AND MORPHOLOGICAL PARAMETERS OF THE BLOOD OF COWS WITH MASTITIS IN DIFFERENT PERIODS OF LACTATION

Posted in 2021, Issue №3 (105) March 2021, VETERINARY SCIENCE | 0 comments

The article explores the biochemical and morphological parameters of the blood of high-producing cows with subclinical and overt mastitis at different periods of lactation. The research was conducted on 51 Holstein-Simmental cows of the “Druzhba” stud farm. The animals were divided into groups according to the terms of lactation(1st, 3rd-5th, 7th-8th month) and their health condition (clinically healthy, with subclinical mastitis and overt mastitis). The blood was collected for morphological and biochemical analysis from all groups. In the course of the study, it was found that the most significant was the fluctuation in the number of white blood cells in the blood. With the development of subclinical mastitis, the number of white blood cells decreases by 9.6-11.4%, while in the case of overt mastitis, it increases by 1.3 – 9.6% compared to the indicators in groups of healthy animals. The study observes an increased level of nitrogen metabolism, disturbed calcium metabolism, and a decrease in carotene content. The level of immunoglobulins in the blood of sick animals decreases, their concentration is 10.0 to 14.9% less than in clinically healthy animals. The research identifies the absence of a significant influence of the lactation period on the hematological parameters under study, which indicates a high similarity of the course of mastitis in cows at different stages of lactation.

DYNAMICS OF THE MORPHOLOGICAL PARAMETERS OF BLOOD IN DOGS WITH CANINE HOOKWORM DERMATITIS (UNCINARIASIS)

Posted in 2020, Issue № 12(102) December 2020, VETERINARY SCIENCE | 0 comments

The causative agent of uncinariasis, Uncinaria stenocephala, belongs to one of the most common parasites in the urban dog population and is very widespread.

Canine uncinariasis is a helminthic disease related to nematodes. The transmission of the pathogen can be both foodborne and percutaneous. It is known that during the migration of Uncinaria larvae through the skin, they injure a large number of vessels, tissues and organs of infected animals. In helminthiases, including uncinariasis, all systems of the animal body are involved in the pathological process, including the changes in their haematological status.

The study of haematological parameters is important for the diagnosis of helminthiasis, monitoring the course of the pathological process in the body and establishing the prognosis of the disease. This is the reason for the decision to examine the dynamics of morphological parameters of the blood of dogs infected with Uncinariae before and after deworming.

SEASONAL AND AGE DYNAMICS OF CANINE UNCINARIASIS

Posted in 2020, Issue № 11(101) November 2020, VETERINARY SCIENCE | 0 comments

Helminthiasis of domestic carnivores is currently one of the most studied and problematic issues in both veterinary medicine and medicine at large, as many helminths that parasitize domestic carnivores are pathogens of human diseases and agricultural productive animals. [5], [6], [9]. In Russia, toxocariasis, dipylidiasis, toxascaris, and uncinariasis are dominant among canine helminthiases in various rural and urban infrastructures. They pose a serious danger not only to a specific host but also to humans [3], [2], [4]. The analyzed literary sources show that there are virtually no studies of helminths and helminthiasis in carnivores in the Rostov region. In this regard, the decision was made to study the helminth fauna as well as the age and seasonal dynamics of uncinariasis in stray dogs entering the animal control facility in Rostov-on-Don.

THE “BIOCENOSIS” PROGRAM FOR EARLY DIAGNOSIS OF INFECTIOUS DISEASES OF REPTILES

Posted in 2020, Issue № 11(101) November 2020, VETERINARY SCIENCE | 0 comments

The article contains a study of the microbiocenoses of various biotopes of reptiles belonging to the following species: corn snake (Pantherophis guttatus), Russian rat snake (Elaphe schrenckii), desert sand boa (Eryx miliaris). In the biotopes of these reptile species, various microorganisms were identified, such as coccoid forms of bacteria, mold fungi, bacteria of the Escherichia coli group, Pseudomonas aeruginosa. The study of the dynamics of microbiocenoses in reptiles makes it possible to model changes in microbiocenotic communities with various indicators of microclimatic parameters. By modeling changes in microbiocenoses, the authors developed a program for the early diagnosis of infectious diseases consisting of a number of algorithms based on the collected database.

For the program to work correctly, it is necessary to study microbiocenoses and the sensitivity of microflora to antibacterial drugs. The cost of the study of one animal is 2,088 rubles. The cost of materials required for the analysis of one animal is 793.25 rubles. The amount required for the normal operation of the “Biocenosis” program to track changes in microbiocenotic communities in animals is 14,619. rubles annually. While the total cost of treatment of a reptile from a chronic infectious disease amounts to 7,170 rubles per reptile in the course of 3 months, the annual amount will be 28,680 rubles. This program helps prevent the following: infection of the host with particularly dangerous forms of pathogenic bacteria; death of the animal; the ability to save up to 14,000 rubles a year for the treatment of a single animals’s chronic infectious diseases.

EFFICIENCY OF USING ACARICIDAL DRUGS OF NATURAL ORIGIN AGAINST PSOROPTES CUNICULI

Posted in 2020, Issue № 06(96) June 2020, VETERINARY SCIENCE | 0 comments

Psoroptic scab, an invasive disease of rabbits, caused by mite Psoroptes cuniculi (Delafond, 1859) and characterized by superficial skin lesions, as well as, in the case of second microflora, damage to the membranes of the brain, is a serious problem in rabbit breeding. Applied aerosols of chemical preparations include cyodrin, acrodex, psoroptol or dermatozole, as well as organophosphorus acaricides cannot provide 100% effect due to the absence of a radically destructive effect on the mite’s eggs. Systemic drugs (neocidol, diazinon) are highly toxic to animals, aquatic organisms and bees. The aim of the research was to develop environmentally friendly preparations of natural origin for the extermination of the Psoroptes cuniculi scabies at industrial farms. The objective of the research was to test new drugs developed at the M. A. Lisavenko Research Institute of Siberia and the Far East on Acariformes and green (insecticidal) soap, which has a toxic effect on insects and mites via plasmolysis, which have undergone wide testing on various garden crops of open and protected ground.
