Inconsistencies in feeding level of dairy cattle to their feed needs leads to various metabolic diseases, including ketosis. The purpose of our work is to study changes in the metabolism of both sexually mature representatives of dairy cattle and young animals obtained from them. The article states the following causal factors of ketosis occurrence in cows: excessive amount of fat substances, imbalance of various chemical elements in feeding diet. The pathology of carbohydrate-fat metabolism during ketosis in cows was characterized by a significant change in blood biochemical parameters, namely, an increase in triglycerides (up to 0.7 ± 0.07 mmol/l), cholesterol (up to 2.7 ± 0.15 mmol/l), non-esterified fatty acids (up to 1.93 ± 0.19 mmol/l), KET (up to 2.4 ± 0.18 mmol/l), low glucose concentration (up to 1.07 ± 0.12 mmol/l) and alkaline reserve (up to 17.8 ± 1.5 mmol/l). Low level of triglycerides, cholesterol, and alkaline reserve, as well as high values of non-esterified fatty acids, KET, and glucose characterize the exchange in calves from cows with ketosis relative to calves born by cows without metabolic pathology.

This article presents quantitative measures of the spread of epizootic foci of African swine fever (ASF) for 2020 in the Primorye Territory. Veterinarians of Primorye have undertaken a range of preventive services to eliminate the foci of the disease and prevent the spread of ASF. They include timely removal of sick animals from private subsidiary farmings. These measures resulted in the elimination of all epizootic foci in the territory of the region. The Veterinary service of the region continues preventive efforts towards prevention of new outbreaks.

The key sector that ensures the country’s food security is a comprehensive enhancement of livestock raising, including animal husbandry. The intensification of dairy production leads to increased metabolic stress in animals. Under such conditions, any technological failure can result in a disorder of the metabolism in cows and the development of metabolic diseases, including ketosis (acetonemia). Ketone bodies in the calf’s body produce an intoxicating effect on its body. The purpose of the study was to analyze the metabolism of young animals (calves) from cows with ketosis. The studies were performed on two groups of newborn young black-and-white breeds. In the biochemical assay of blood, the indicators of protein metabolism (total protein, albumins, globulins), glucose, acetone (ketone) bodies, triglycerides were considered, which were fulfilled on the selected young animals at the age of 3, 10 and 15 days. It was revealed that the condition of the metabolic processes in the body of young cows with ketosis differs considerably from the studied indicators of the metabolism of young cows of healthy cattle. By the 15th day of life, the following indicators were found in the blood of young cows with ketosis: total protein-56.3±2.7 g / l, albumins-57.40±4.14%, betta-globulins-20.59±5.84%, gamma-globulins-11.42±1.66 %, triglycerides-0.44±0.02 mmol/l, acetone bodies-1.26 ±0.06 mmol/l, glucose-5.54±0.25 mmol/l. Conclusion: the calves with metabolic pathology are born from cows with ketosis. It is characterized by dysproteinemia, a high content of ketones and a lower concentration of triglycerides in the blood comparing to the similar animals born from healthy cows.
