The Vietnamese word "sổi" primarily means "barren" or "sterile," particularly when referring to female animals that are unable to conceive or produce offspring.
Con bò này sổi, nên không thể có bê.
(This cow is barren, so it cannot have a calf.)
Chúng tôi cần thay thế con gà sổi trong đàn.
(We need to replace the barren hen in the flock.)
In summary, "sổi" is a specific term used to describe the barrenness or sterility of female animals.
