| description | Studying the antioxidant status of cow's milk can provide information both on the physiological state of the productive animal and on the resulting product in terms of its functional value, taste and characteristics affecting storage. The purpose of the work is to study milk samples from Holstein cows of the black-and-white breed with different periods of lactation (up to 30-60 days, 60-90, 90-180, more than 180 days) for the activity of antioxidant protection factors during a number of months of autumn, winter and spring periods. The total amount of water-soluble antioxidants (TAWSA) of milk was determined by the amperometric method, the activity of ceruloplasmin by the modified Ravin method, the microelement composition by the method of atomic adsorption spectrometry, the concentration of vitamin C by the titrimetric method, and the catalase number by the permanganatometry method. Patterns have been identified between the seasonal dynamics of zinc and catalase in milk: in January, in a group of animals with a lactation period of 30-300 days, catalase activity and zinc content are higher by 21.6 and 17.4 % , respectively, than in cows with a lactation period of 15-30 days; in February, on the contrary, these indicators are higher in the group of animals with a lactation period of 15-30 days (by 29.6 and 30.4 %, respectively); in March, in the group of animals with a lactation period of 15-30 days, catalase activity and zinc levels are lower (by 26.3 and 10.6 %) than in cows with a lactation period of more than 30 days. There is a decrease in TAWSA with an increase in the number of lactation days. The concentration of TCWA in the milk of cows lactating for more than 180 days decreased in November and March, by 25.9 and 13.5 %, respectively, compared with a lactation period of 30-60 days, in February – by 18.8 % compared with animals lactating 60-90 days. The obtained data on TAWSA are directly proportional to changes in vitamin C and inversely proportional to ceruloplasmin. The data obtained can serve as important guidelines in determining “reference indicators” for cows’ milk. |
