My mistake
A male donkey is called a
jack,, a female a
jenny, or less correctly, a jennet, and offspring a
foal (male:
colt, female
filly). In the western United States, a small donkey is sometimes called a
burro. A
mule is the offspring of a male donkey and a female horse. The mating of a male horse and a female donkey produces a
hinny. While different species of the horse family can interbreed, offspring, such as the mule and hinny, are almost invariably
sterile.
Donkey=ass=jack=jackass= con lừa (đực)
jenny= lừa cái
Mule= con la
Hinny = con lai
