The Story of Diafarm

Diafarm was founded by veterinarian Johs. Gjelstrup in 1980. In the 1970s he had his own veterinary clinic in the center of Vejle, where people came with their sick pets.

As the years passed, he could see that many of the problems the pets had were caused by feed imbalances, and therefore he began to study the scientific literature in the field. In the back room of the clinic, he developed his own special vitamin and mineral mixtures, with which he successfully treated the pets.

The rumor spread, and the customers came from afar to get their pets treated. The demand grew so much that Johs. had to make a life-changing choice.

Veterinarian or manufacturer?
The desire to develop and manufacture new products to alleviate the various problems of the pets won. In 1994, the veterinary clinic was sold, and Johs devoted himself full time to the production in Diafarm.

The business began to grow. The product range expanded with many different vitamin and mineral supplements. Pet shampoos against fur problems, various cleaning products, gel types and much more were developed. New types of customers came, and Diafarm started producing many private label products.

The sons take over
In the 1990s Johs.’ two sons, Jesper and Jacob, entered the company, and over the years it grew larger and came to include even more product groups.

From lying in the center of Vejle for almost a lifetime, Diafarm moved in 2016 to new and modern production facility close to the E45 motorway, but still with postal code in Vejle. The move was due to the need for more space and larger machines in relation to meeting customer demand.

Through the years, the sons have just as slowly taken over the company, but not until 2018 did Johs finally retire.
