[Effectiveness of potassium iodide in ovarian cysts in cows]

A trial was carried out with the treatment of a total of 64 cows having ovarial cysts. Thirty-one of the animals were given potassium iodate in the course of seven days at rates of 3, 4, 5, 6, 7, 8 and 9g with the concentrates, and thirty-three were offered potassium iodate at the same rates in the form of a 1 per cent solution. The medical treatment was performed along with the study of the blood serum for total protein and protein fractions, and the examination of the thyroid activity by means of the factor F after the Modestov-Arsenyev's method. The following conclusions were made: 1. The administration of potassium iodate with the concentrates for 7 days at the rates mentioned above produces a good therapeutic effect, is fully absorbed (as found in the cysts content), and total conception amounts to 86.6 per cent. 2. The albumin level in the serum rises by 1.9 per cent in cows given potassium iodate with the concentrates, and by 1.7 per cent in cows given potassium iodate as a 1 per cent solution. 3. Factor F shows decrease by 28 per cent in animals treated via the concentrated fodder, and by 38.6 per cent in cows offered potassium iodate as 1 per cent solution.
