Journal Title: Біологія тварин - Year 2015, Vol 17, Issue 2
Abstract
Vitamin D-status of early postnatal calves obtained from high-performance cows were treated with cholecalciferol orally or intramuscularly in winter-stall period was investigated.Vitamin D was added to the diet in daily dose of 30 IU per 1 kg of body weight for a month starting 7–10 days before the predicted date of calving, and then in 5–7 day after calving. Intramuscularly vitamin D was administered: the first time — at 7–10 days before the predicted date of calving and three more times starting from 5–7th day after calving every 7 days at a dose of 210 IU per 1 kg of body weight for each input.For studies in calves for took blood 5–7- and 28–30-th day after birth. In the blood examined the contents of the 25-hydroxyvitamin D, total calcium and its fractions, inorganic phosphorus, magnesium and alkaline phosphatase activity. It was established that calves derived from cows that in the last days of gestation and after calving were treated with cholecalciferol orally or intramuscularly had higher blood levels of 25-OHD3, total calcium, bounded with protein calcium and ultrafiltrated calcium, inorganic phosphorus, magnesium and lower activity of alkaline phosphatase compared to calves from cows of the control group. Blood serum of calves born by cow sthat were intramuscular injected with vitamin D3 characterized by significantly higher content of 25-OH D3, calcium and inorganic phosphorus at 5–7th and 28–30th day after birth, compared to calves of control group. Supplementation of cow diet with cholecalciferol showed the effectt on these calf blood parameters onlyon 28–30thday after birth. Thus, the introduction of cholecalciferol cows in late pregnancy and early lactation is essential to ensure their calves this vitamin in the early postnatal period.
