Daily Milk Production in Cows: The Effect on the Concentration Level of Total Cholesterol in Blood Serum
The modern way of cultivation, that is, the technology used for keeping and exploitation of dairy cows, is aimed at continuous increase in the intensity of milk production and maximizing the use of genetically high milk. The burden on the metabolism of high-productive cows is most evident in late gravidity and puerperium. The link between the production characteristics of high-producing dairy cows (daily milk production) and the metabolic capacity of their organism is still insufficiently clear, and so a legitimate reason for the research. The concentration of total cholesterol in the blood serum of cows in lactation varies in a wide range (1.3-9.36 mmol / L). Many internal and external factors affect the elevated or decreased level of total cholesterol concentration in blood serum of lactating cows. According to the recent studies, the amount of daily milk production of cows who lived in farm conditions of breeding and keeping, does not have a significant effect on the level of total cholesterol in the blood serum, what was determined using single linear regression analysis.
