DO NOT under ANY circumstances get the placenta out of a cow!! You will invite serious infection in the uterus (called Metritis) if you do this, causing serious illness if not death of your animal. You MUST let the cow push the placenta out by herself, and assist her with an injection of Oxytocin to help push it out quicker since it is a retained placenta.
ONLY remove the placenta IF AND ONLY IF A) She has a prolapsed uterus or B) she has had a C-section. And only THEN should you let a VETERINARIAN do the job.
A cow
A "cow" is a cow when that "cow" is a she and she has given birth to at least one calf.
A springer or springing cow.
The term for a cow that gives birth to a bull is simply referred to as a "cow" or "mother cow." However, if you are specifically asking about the act of a cow giving birth to a bull, it can be described as the cow "calving." The newborn male is called a "bull calf."
It should only be a matter of a couple hours.
A pregnant cow who gives birth is a mother.
It could mean that a cow is ready to give birth.
A dam cow is a female. In livestock terminology, "dam" refers to the mother of an animal, particularly in breeding contexts. Therefore, a dam cow specifically indicates a female cow that has given birth or is capable of giving birth.
A calving cow if she's in the process of giving birth (which is what freshening is referred to), or a new momma cow (or just plain new mother) if she's already given birth.
A female cow is called a "cow" - if it has not given birth it can be called a "heifer". Perhaps you were thinking of a "cow" called 'Daisey'.
A cow shouldn't be bleeding after giving birth. She may have a torn uterus, so you'd better get the vet out ASAP.
What kind of question is this?? A cow has already given birth, so there's no need to give her anything to make her give birth faster. This is a poorly worded question, and confusing at that.
