The facial design and structure can’t predict the milk production potential
The camels look different based on their phenotypes (visual appearance) but they almost have very similar traits for the production. The visuals are from the milking camels at the milking parlor in Alain, apparently, they have different faces, nostrils, eyes, eyelids hair but they all are producing almost the same quantity of milk. Based on the record, their milk is more than 10 liters per camel per day. Maybe to some extent, we can guess the high-yielding camels by their face (imagining the breed for high yield) but with little accuracy. Here is a short video of the faces.
