Depending on the breed, beef calves should weigh about 600-800 lbs by the age of 8 months.
This depends on the breed. Some calves will weigh around 750 lbs or lighter at 8 months of age; others may weigh around 900 lbs.
Around 6 to 8 months of age.
I have a 1 year old male who weighs 75-80 lbs. At 8 months he was about 50-60 lbs. A female will weigh 10 to 15 lbs less.
8 pounds 14 ounces
Depends on the breed and body condition of the calf. A 600 lb Jersey calf can be around 7 to 8 months old, whereas a 600 lb miniature calf may not be a calf at all, but a 15 month old heifer or bull. A soggy Angus calf at 600 lbs may be at around 5 to 6 months of age.
My male dorkie is 8 months old and weigh 10 lbs. However, I have no idea how much the parents weighed.
Negative three to four months, assuming the cow gets bred two months after calving and the calf is weaned at six months of age. Seriously, a cow is already bred and into her second trimester when her calf is weaned. Cows are not like human females where they can only get pregnant again at least a year or 8 to 12 months post-partum.
That would depend entirely on the length of the mother. Calves are born the length of the mother's head. Sizes vary from 8 feet (under 1000 lbs or 453 kilograms) to 20 feet or more (3000 lbs or more or 1360 killograms or more!)
Female Hippos attain sexual maturity at around 6 years of age. Males reach sexual maturity at around 7.5 years of age. However, males don't get to mate until they are much larger and older. Hippos have a gestation period of around 8 months after which a single hippo calf is born. Baby hippos are born under water and weigh around 25 to 45 kilograms in weight (60 to 110 pounds). They are around 125 cms (50 inches) in length at birth.

8 months
The average weaning time would be 8-10 months. The mother will naturally wean the calf around 12 months.
