Abstract
The dynamics of L-ascorbic acid was studied in 68 cows and 91 calves at an age from one to ten days in the period from November to April. The study was conducted in two maternal stocks in a supply area of a large-capacity calf-house located in the beet-growing region. L-ascorbic acid in the blood serum was determined accoring to King. The lowest average levels of L-ascorbic acid were found in February (cows 0.35 mg%, calves 1.02 mg%), and the highest in April (cows 1.00 mg%, calves 2.52 mg%). The level of L-ascorbic acid descended during ontogenesis from the value found at birth (6.72 mg%); the values of the first postpartal day are significantly higher in comparison with all the remainind observations. The results constituted a basis for a working hypothesis on the importance of colostrum as an exogenous source of L-ascorbic acid for calves.
