A +9 Birthweight EPD for a cow (assuming it is a +9 EPD that you're referring to) means that, in comparison to other cows of the same breed, size, weight, and environmental conditions they were raised in, that cow has a VERY high birth weight in comparison to the average (being an EPD of 0). That cow may be 9 lbs heavier at birth than the other cows, and/or she gave birth to a calf that weighed 9 lbs heavier than what the other cows (all of the same breed, age, weight, frame size, raised in the same environmental conditions, etc.) had.
Copulation or conception. This occurs when the bull ejaculates sperm into the cow, which encourages a series of events that allows a cow to become pregnant and give birth to a calf over 9 months later.
No. A cow only gives birth to one baby per year (on occasion two).
Cows give birth by going into labor and delivering the calf typically from standing position after a gestation period of around 9 months. Assistance from a veterinarian may be needed in some cases. The process should be monitored closely to ensure the safety of the cow and the calf.
A cow's gestation period is around 9 months, or approximately 283 days. A calf typically weighs between 60 to 100 pounds at birth, depending on the breed of the cow.
A cow is generally and usually expected to give birth only once a year. However cows can give birth to calves once every 11 months. Occasionally a cow will give birth to a calf 10 months after her previous parturition, but that is quite rare.
Zebu cows usually have quite a long gestation period, which can stretch from 290 to 300 days in length.
Dairy cattle are usually able to produce milk for about 7-9 years, this may vary between each cow. Many factors are present to determine how long a cow can produce milk such as, genetic structure, longevity, birth weights of calves born by the cow, and conformation.

A heavily pregnant cow, or a long-bred cow. Or, a cow that is expecting soon.
Cows are typically bred once a year, with a gestation period of about 9 months. This means a cow can be pregnant once a year and give birth to one calf annually.
No.
The best time to let the bull in with the cow and calf is around 60 days after the cow gave birth. That is the time she will be receptive and ready to conceive another calf. You can keep the bull in with her and her calf until she is about to calve again, which will be in a 9 months and a couple weeks.
