Utilisation of iodine from different sources in pigs.

Balance experiments have demonstrated that growing pigs fed a ration consisting of wheat, barley, extracted soya meal, dicalciumphosphate, and iodine-free feeding salt utilised 48.8% of the received iodine. The tested supplementary iodine sources included potassium iodide (KI), ethylenediamine dihydroiodide (EDDI), iodine humate (HUI) prepared from iodine acid (HIO3), and the product P containing 0.

Congenital fibropapillomatosis in a piglet.

We report a case of congenital fibropapillomatosis in the head and neck of a piglet from a swine breeding farm where sporadic cutaneous papillomas of the prepuce and scrotum had previously occurred in several boars. Histologically, the tumor consisted of multiple exophytic, papillary projections composed of branching, densely cellular, fibrovascular stalks covered by hyperplastic keratizing squamous epithelium. Ultrastructural examination failed to reveal viral particles.

[Occurrence of struma in cattle in the Czech Republic].

In the years 1988 to 1995 among 1355 cattle examined in the frame of iodine deficiency studies in the Czech Republic 404 animals (30%) showed congenital struma. Clinical and postmortal findings are described. A monitoring of iodine content in milk showed lower values in herds with struma prevalence.

Contribution to the symptomatology of experimental bovine cysticercosis.

Results of clinical and laboratory examination of animals experimentally infected with Taenia saginata eggs are described. At the early stage of infection, increased temperature, cough, muscle shaking and unstable pace were observed. The locomotive disorders disappeared only on day 50 p.

Pathology and neonatal infection of calves with Cysticercus bovis.

It was demonstrated that the tissue reaction around the developing C. bovis in neonatally infected calves (4 days after birth) differs quantitatively and partly also qualitatively from the reaction in calves infected at the age of several months. In neonatal infection, the foci caused by cysticerci were 3-4-times smaller on day 14 p.
