Goitrogenic effects of extracted rapeseed meal and nitrates in scheep and their progeny.
Original language description
Three groups of sheep of the breed "Šumavská ovce" were fed meadow hay completed with extracted rapeseed meal, containing 4.2 mmol of glucosinolates, and 4 g of sodium nitrate per animal per day for 382 days. Moreover, two of the groups received parenterally 0.25 mg iodine and 0.15 mg sodium selenite per animal and per day at weekly intervals. The fourth group, also supplemented with iodine and selenium, was fed a diet without the addition of nitrate in which extracted rapeseed meal was replaced with oats meal. Biochemical analyses included determination of iodine concentrations in colostrum and milk of ewes and iodine, thyroxine and triiodothyronine concentrations in blood plasma of lambs from birth up to the age of 60 days. Thyroids of five necropsied lambs were weighed and examined by light and electron microscopy. Hypothyreosis with sporadic occurrence of congenital goitre and low concentrations of iodine and thyroxine in blood plasma were observed in the progeny of the ewes receiv
