The cows arrived on a Qatar Airways cargo plane via Budapest on Tuesday and were taken to a new, purpose-built dairy.
Qatari firm Power International has bought the cattle, with chairman Moutaz al-Khayyat telling Bloomberg last month that once all the cows were flown in, they would meet about 30% of the country’s dairy needs.
The products will be sold under a new dairy brand Mr al-Khayyat has launched.
It has been five weeks since Saudi Arabia, Bahrain, Egypt and the United Arab Emirates began the boycott over Qatar’s alleged support of terrorism and ties with Iran. Qatar denies wrongdoing.
Before the blockade, most of the dairy products sold in Qatar were imported across the land border with Saudi Arabia.
The Gulf kingdom has also been looking at securing new trade routes and suppliers of food, including yoghurt imported from Turkey and dried goods from Morocco and Iran.
