In Jain philosophy, pratyek vanaspatikaay (प्रत्येक वनस्पतिकाय) refers to single-sensed (ekendriya) beings that are plants with only one soul per body, such as a mango tree, banana tree, etc. These are contrasted with sadharan vanaspatikaay (common-bodied plant life) where many souls inhabit one body, like in roots, tubers, and some algae.

Milk does not fall under pratyek vanaspatikaay. Milk is an animal product, specifically produced by mammals, and it is not considered a living being (jiva) in the same way as plant life. In Jainism, milk does not possess its own soul (jiva); rather, it is regarded as a secretion from an animal, which is a higher form of life (trasa jiva—possessing more than one sense).

Therefore, according to Jain classification:

• Milk is not vanaspatikaay at all (neither pratyek nor sadharan).
• Milk is not a living being (jiva) itself, but its consumption is discussed under the ethics of ahimsa (non-violence) concerning the treatment of animals.

Summary: No, milk does not fall under pratyek vanaspatikaay.
