counterparts, mainly because of the difference  in the diets of dairy cattle. In Australia,  

cows graze on grass rich in beta-carotene,  which gives the butter its yellow hue.

In contrast, many European cattle are housed  in barns and fed dry food containing lower  

levels of beta carotene, resulting in less  yellow butter. The diet of dairy cows plays  

a crucial role in the quality of milk and dairy  products, as evidenced by Canada's buttergate  

incident in 2021, where adding palm oil to  cattle's diet altered the texture of butter.
