Stalosan was originally invented by veterinarian Løje in 1964. This made Stalosan the first and only dry animal-hygiene product in the world. The following is a declaration about Stalosan written by Dr Løje almost 25 years after the product was launched:
Declaration by Dr Løje, DVM, 17 May 1989
“In the course of my many years of working at a very large and diverse veterinary practice, I have experienced how difficult it is to maintain a reasonable level of animal hygiene with ordinary disinfection of livestock housing. The livestock had to be moved out and the surfaces had to be washed and scrubbed, which was a very troublesome undertaking. This gave me the idea to invent a form of dry disinfectant for use after ordinary daily cleaning and possibly also in loose housing systems without having to move the animals.
This resulted in Stalosan. The product is primarily a combination of familiar substances whose special composition has a drying, disinfectant and air-cleaning effect. Stalosan has a drying effect by means of its ability to absorb considerable amounts of moisture, which helps to damage any coccids in deep bedding, for instance. Disinfection is a complex process which also must combat fungi as they can be very harmful to airways, not least in chickens. According to studies by the two Danish laboratories Stein and Quist, Stalosan also effectively eradicates a number of pathogenic bacteria: E-coli, Streptococci, Staphylococci, Salmonella, Haemophilus, Pasteurella, Pseudomonas, etc.
An essential factor for Stalosan range of effect is its great capacity to bind ammonia fumes emanating from decomposing animal manure, which is also further enriched by this process. Numerous studies have proven these fumes to be very harmful for animal respiratory organs, not least the pulmonary bronchioles. Stalosan also binds harmful sulphur fumes to some extent. These air-purifying effects help to reduce ventilation costs while providing a far healthier and fresher environment for both animals and carers. Stalosan can be used for all livestock and there have been no signs of even the slightest side effects over the some 25 years it has been marketed in Denmark and neighbouring countries. I’ve also used it in my practice and on my own farm. However, it should be used with caution for sheep as they are quite sensitive to a few of the components in Stalosan, even when observing the instructions enclosed. This declaration applies only to the original Stalosan. It is difficult to assess the consequences of any attempted copy products.”
