Method for improving physical health and weight increase of animals in mass breeding system, involves processing air in system with active agent

摘要

The method involves processing the air in the system with an active agent. A mixture made from a high-boiling aldehyde, particularly jasmonal H and a high-boiling phenol, particularly thymol are used as active agent. The aldehyde and phenol are provided in a specific weight ratio. The active mixture is released slowly and evaporated from the carrier material. The active mixture is distributed in a matrix of a cross-linked, hydrophilic group containing polymers, to form a gel-like mass, from which the active agent is released slowly and evaporated.
