Already a low concentration of ammonia causes irritation to the mucous membranes of the eyes and respiratory tract. Pathogens penetrate the injured mucosa and weaken the immune defence. This often leads to secondary infections, e.g. in the gastrointestinal tract, which exacerbate the disease and adversely affect the course. The bad condition affects food intake and feed conversion. The economic damage, caused by respiratory diseases in the rearing of poultry and pigs, is enormous. An improved stall hygiene and the reduction of ammonia in the house air – by use of SANBIO TERRA – are important prophylactic measures to improve animal health. The improve of the body’s defenses and deactivation of toxins can be achieved by the use of the complementary product SANBIO SANA.
