[Pathology of congenital bromine deficit (experimental observation)].

Pathology of congenital bromine deficiency is described in a she-goat whose mother was kept for two years on a bromine deficient diet. Anomalies of the bones and joints of the anterior limbs, disturbances of carbohydrate, lipid and mineral metabolism in the form of liver, kidney and lymph nodes glycogenosis, liver fat degeneration, haemosiderosis of the liver, spleen and lungs were found. Moderate thymomegaly with hyperplasia of the cortex and an increase in the number of Hassal bodies, microcystic ovary transformation, adrenal adenomatosis, cheilitis, flossitis, focal proliferative extracapillary glomerulonephritis were also observed.

[Pathology of experimental hypocobaltosis in goats].

Histological changes in chronic experimental hypocobaltosis manifest as atrophic-degenerative alterations and restructuring of endocrine organs as well as a decrease in systemic resistance (accidental transformation of the thymus, duodenitis and sigmoiditis in some animals). Pronounced fat hepatosis and signs of iron metabolism damage (cheilitis, spleen siderosis) are found as well.

[Testing of extracted particles from winter rapeseed with different glucosinolate levels in swine with special reference to the iodine supply. 2. Thyroid hormone status, histomorphometric findings and iodine content of the thyroid gland].

In the experiment, 2 x 12 growing pigs received 19 or 6.7 mmol glucosinolates + aglucones/kg feed via conventional rapeseed meal (RSM) or RSM of a newly bred variety. These pigs and 24 littermates pair fed with a soya bean meal (SBM) diet were subdivided in groups of 4 animals each.

Trace element intake (zinc, manganese, copper, molybdenum, iodine and nickel) of humans in Thuringia and Brandenburg of the Fed. Rep. of Germany.

The daily dry matter intake of 56 test persons between 20 and 60 years of age from four geographic groups (Wusterhausen and Vetschau in Brandenburg; Jena and Bad Langensalza in Thuringia) was registered on 7 consecutive days by means of the duplicate method. The Zn, Mn, Cu, Mo, I and Ni content of food and beverage dry matter and the daily intake of these trace elements were determined. During the test period, the ration contained 24-29 mg zinc, 6.

Effect of varying glucosinolate and iodine intake via rapeseed meal diets on serum thyroid hormone level and total iodine in the thyroid in growing pigs.

In a trial with 50 fattening pigs (20 kg initial body weight), the effect of untreated rapeseed meal (RSM) (148 mmol glucosinolates and aglucones per kg dry matter) on the thyroid was compared with RSM treated with Cu2+ (9.5 mmol glucosinolates and aglucones per kg dry matter) and soybean meal (SBM). The diets containing 8% RSM were supplemented with 0.
