During the Royal Trip to the Kingdom of Denmark in 1960, a visit to a dairy cattle farm and a milk processing plant was put in His Majesty's itinerary. The purpose was to study the possibility of establishing a milk farm and milk industry in Thailand.
On 12 January 1962, His Majesty presided over the Opening Ceremony of Suan Chitralada Dairy Farm. For this reason, dairy farmers proudly mention dairy farming and processed milk industry as the "Royally-Granted Career". One important success coming from this project has been the Nongpho Milk Cow Cooperative in Ratchaburi province.
