Exchange of vitamins in cows suffering from ketosis

Abstract

Ketosis of dairy cows in suburban farms occurs on average in 15.18% of animals. The highest percentage of sick cows was at the end of the stall, i.e. March-April (average 20.67%). in the blood of these cows there was a significant increase in the content of ketone bodies, the level of which reached 3,03 Ф 0,40 mmol/l, i.e. was more than 4,0 times higher. A decrease in blood glucose levels in patients with cow ketosis to 2.16 Ф 0.12 mmol/l or 24.7% (compared to healthy animals) was characterized by a low level of glyconeogenesis. Decrease in the indices of acidic capacity and reserve alkalinity of blood serum in sick cows in 1,2 times in comparison with healthy animals testify to the development of acidic state. In blood and liver in patients with cow ketosis there was a significant decrease in total thiamine and Riboflavin compared with similar indicators in healthy cows. The decrease in the concentration of total Ri boflavin in patients with cow ketosis occurred in the blood due to the strongly bound form, and in the liver - due to the acid-hydrolyzable form. In the blood of infected animals was also observed a decrease in the concentration of vitamin C by 26.1 %, and vitamin b - 12 is 53.9 %. It is believed that the decrease in blood ruminant b vitamins, including B1, B2 and B12 occurs under the influence of causes that lead to a decrease in the activity of the pancreatic microflora. The decrease in the level of vitamin C occurs in patients with cow ketosis due to the established fact of fatty degeneration, where the formation of this vitamin.
