[Effect of nitrates transferred from the mother on fetal hemoglobin and methemoglobin dynamics of lambs].

Abstract

Investigated were 16 pregnant merino sheep, 5-7 years old with active weight 50 kg, divided into two groups--control and experimental. The experimental group was fed with forage, containing 0.65 nitrates from the dry substance of the ration. It was established that the elimination of part of the taken with the forage nitrates is realized through the milk. Traced were the periods of substitution of the fetal haemoglobin with adult in new-born lambs, and the influence of the liberated with the milk nitrates, taken by the sucking lambs, on the quantity of the methemoglobin.
