Highlights

  • The determination of iodine level in milk from various regions of Czechoslovakia was carried out

  • The problems connected with the iodine content in milk have gained importance with the introduction of disinfectants, based on active iodine, employed for disinfection of mammary glands of dairy cows as well as that of milking devices

  • All the authors agreed that the application of iodophores is always accompanied by the increase of iodine level in milk, the extent of this increase being, dependent on the type of preparation, the concentration of active iodine, the application form and other factors

Summary

Materials and Methods

The samples of milk for the iodine level determination were randomly taken from the production lines of various dairies such as Lacrum Brno, Laktos Praha and PMV Works Opocno and Hradec Kr:ilove. Preparatory phase - Iodine levels in milk of both groups were determined for 16 days prior to start of the experiment. 2. 1st application - For the period of 19 days the Jodonal M solution of a given concentration was applied to the experimental group. The samples of bulk milk were taken twice a day from both groups of animals for the whole duration of experiment. The experiment was carried out by Dairy Research Institute Prague and Central State Veterinary Institute Prague, the analyses being effected partially at the University of Veterinary Science, Bmo, and partially at the above-mentioned laboratories. Chemicals used for making solutions were of analytical grade (Lachema)
