There is no such thing as a "bull cow." Either you are talking about a bull, or a "cow" which would be a weanling heifer. As such this all depends on the breed of that animal.
The weight of the average cow hide is around 55 pounds. The weight of the average bull hide is around 72 pounds.
Cows can weigh from as little as 900 lbs to as large as 1800 lbs. Bulls weigh from as little as 1700 lbs to more than 2800 lbs.
Because a steer doesn't have the testosterone to build as much muscle as bulls have. Thus steers weigh about as much as a cow when allowed to reach maturity (at around 2 to 5 years of age).
That really ultimately depends on the breed of that bull calf.
A Belgian Blue cow can weigh an average of around 1500 lbs.
Bull hippos can grow to be twice or thrice the size of a bull gaur. However, a bull gaur can weigh about the same as a cow hippo.
The weight of the average cow hide is around 55 pounds. The weight of the average bull hide is around 72 pounds.
The answer to this question is totally dependent on what breed that this 15 month-old so-called "cow" is.

This depends on the breed. Smaller breeds may only weigh around 70 to 80 lbs at 1 month of age; other breeds that are larger can weigh around 200 or 300 lbs at this age.
A Belgian Blue cow can weigh an average of around 1500 lbs.
There is no such thing as a "female cow" nor a "male cow." "Cow" refers to the female of any species including the domestic bovine, and is not a name of a specific animal. The male of a domestic bovine is called a bull, and the female (mature) a cow. To answer your question, it is the bull that is the larger of the two in most cases, such as within breeds and when the bull and the cow are the same age. But, if you compare between breeds, such as if the bull is a Dexter and the cow a Holstein, or if the bull is much younger than the cow, then the opposite may be true.
In a way, but remember male cows don't exist, unless they are male and look like a cow, which is often if you find a "bull" that looks like a cow but has testicles where there should be an udder. Ultimately, bulls are bulls, and are the much more masculine counterpart of the female bovine (the 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."
