Marine mammals often become entangled in various objects of anthropogenic origin floating on the surface of the water. Plastic, polyethylene, synthetic packing straps, and fishing gear threaten marine mammals in the water and on land. The study was carried out on 29 specimens of Callorhinus ursinus. We used a combined Zoletil 100 and Medetin 1% for...
Article
Highly productive dairy farming requires strict adherence to the technology of feeding and keeping cows and competent herd management. Cows with liver pathologies during the transit period are tough to treat. We conducted studies of cows' health status after calving to identify biochemical signs of liver pathology and associated metabolic disorders...
Article
Steatosis is a common disease in dairy cattle, especially during the transit period. Usually, the subclinical form of hepatosis is evenly distributed in the population throughout the year: 30-70% of cows can be affected. However, severe (toxic) steatosis is rare. The study was carried out on 505 dairy cows in the North-West of Russia in July-August...

Currently, non-invasive animal research methods continue to develop, one of which is bioelectrical impedance analysis to determine the body's water, fat, fat-free, and cell mass, which reflects the assessment of the body's liquids. The electrical and biological significance of impedance analysis lies in the fact that the measurement of the resistan...
Article
In dogs of service breeds, cardiopathology is one of the most common diseases of non-infectious etiology. Dilated cardiomyopathy (DCM) is frequently reported among other heart conditions in large and giant breed dogs. As a result of our previous work, it has been established that DCM of varying severity is recorded in no less than 25% of service do...
Article
The genital form of mycoplasmosis is a common disease among cattle in the North-West region of the Russian Federation. In the initial period of illness, cows retain reproductive function and are capable of maintaining pregnancy. It is known that any mother's illness during pregnancy affects the fetus's body, including its immune system. Based on th...

Diseases of the digestive system of calves, including enteritis, are an urgent problem in dairy farming. The disease occurs under the influence of various causes and often has a mixed etiology. The use of veterinary bacterial drugs today has found its application in preventing and treating many animal diseases. At the same time, valuable microorgan...

The article considers a clinical case of uterine fibroids in an East European Shepherd dog. The owners complained of uncontrolled urination in the animal, which was aggravated over the past three months, as well as an increase in the abdomen, refusal of active physical exertion, shortness of breath when going up and down stairs, and decreased activ...
Article
The article presents the results of using a drug with a controlled long-term release of a substance in a bolus form, which was administered orally to lactating cows with a predisposition to the development of metabolic disorders - first of all, the development of ketosis. As a result of the work, it was determined that in the experimental group of...
Article
Maintaining reproductive health is an urgent task in intensive livestock farming. The study of the influence of pathogens of the Mycoplasmataceae family on the microecology and protective properties of the vagina is of particular interest. The studies were carried out on non-pregnant cows 3–4 years old. Was formed 2 groups of 8 animals each. The fi...
Article
The aim of the study was to research the effect of selenium-containing drugs on the efficiency of artificial hatching, using them in the composition of feeding of starter-families. The experiment was conducted in a private apiary located in the Penza region, Russia (30 bee colonies). The predominant honey plants - melilot, rose bay. The average pro...
Article
Cows that received an over-calorie diet in the final phase of lactation are prone to liver lipidosis. The task of our research is to study the dynamics of cholesterol and triglycerides in cows with fatty hepatosis during the transit period. A group of 20 dry cows was formed. In the blood serum of cows, the concentration of cholesterol and triglycer...
Article
The purpose of these studies was to determine the indicators of cellular and humoral immunity of calves. Compared to calves obtained from untreated cows, the number of T-lymphocytes in young calves born from cows treated with Timolin increased the level of T-cells to 32.9%, while using Timosplenin 45%. As a result of the use of immunomodulators in...
Article
Steatosis is an often detected pathology in cows. Due to hypertension, the load on the urinary system increases, which is accompanied by kidney damage. Often in cows with steatosis, necritis, pyelitis and kidney dystrophy are detected at autopsy. The goal of this study was to determine the characteristic features of kidney damage in cows with steat...
Article
Carnitine is actively used in medicine in the treatment of male infertility. L-carnitine is an organic acid that normalizes the balance of oxidative and antioxidant processes. Bulls (n = 15) with low sperm quality (low sperm activity) were selected. The bulls were injected intramuscularly L-carnitine solution (NaturVet, Australia) at the rate of 1...

... The formation of young animals in the first two months of life is a complex period rich in stressful factors, implying complex processes of adaptation to external environmental conditions, which negatively affect the level of animal's metabolism and health in general [1,2]. The aggravating factor is the immaturity of the immune system of the calves, the destruction of colostral immunoglobulins [3], starting from seven days of life, and the transition period in feeding at an older age. ...
... Aflatoxins are produced by Aspergillus and are the most dangerous. They disrupt the functioning of the kidneys and liver, reduce immunity, and, in addition, are carcinogens [6]. Other authors also point out the possibility of excretion of this mycotoxin with milk, which is dangerous for calves [7]. ...
