Starting March 1, all farm animals in the Russian Federation must be marked and registered in the Horriot component of the FSIS VetIS (Rosselkhoznadzor system). Until September 1, 2024, cattle, pigs, and poultry must be registered, with poultry on private farms having different labeling periods depending on the number of birds. Horses, donkeys, mules, and hinnies also need to be marked by September 1 of this year, except for those on private farms, which must be registered by March 1 of the next year. Owners are responsible for marking the animals at their own expense, and registration is free and done by state veterinary services. The Horriot component aims to maintain records of animals and track their movements and veterinary procedures.
