Longstim is a combination of synergistic antibiotics for the treatment of mycoplasmosis and a wide range of other bacterial infections in pigeons and cage birds. The two antibiotics in Longstim have proven to be a valuable tool in the treatment and prevention of a wide range of upper respiratory tract infections (including mycoplasmosis). This product is very safe. It can be used routinely once a month during the racing season for the prevention of upper respiratory tract diseases, such as "phlegm in the throat." It is ineffective against psittacosis (parrot fever or avian influenza). In these cases, doxbiotics should be used. Available sizes: 200g, 400g. Contains: Amoxicillin trihydrate 5% w/w, Tylosin tartrate 10% w/w
