Abstract

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.
