LenersanPoortman was founded in 1803 as Lenersan & Co’s Exporthandel N.V. and traded in grains, seeds, legumes, products for human consumption, animal feed and by-products.

Poortman N.V. was founded in 1868; Lenersan and Poortman merged in 1969. In 1973 LenersanPoortman was taken over by the Swiss company SiberHegner. The company, located in Rotterdam, built new premises and a factory in Dordrecht, which was opened in 1978. The main reason for the relocation was the location next to the Merwede river.

In 1982 Holland Diervoeders was also incorporated. SiberHegner in the meantime merged with Diethelm Keller. The two companies, Holland Diervoeders and LenersanPoortman, now operated together under the name DKSH Netherlands B.V. from Dordrecht. In 2011 DKSH Netherlands B.V. was sold to the Depre Group. The new entity was named Holland Diervoeders B.V.
