This all depends on the breed. As such, your veterinarian would have a better idea of what the optimum pelvic size is for your particular breed or breed-mix of heifers you are wanting to get bred.

Why are calves from first calved heifers smaller?
Heifers are still growing and maturing themselves, so a lot of resources being put into the calf's growth still need to be put into the heifer to keep her growing as well.
What age should bulls and heifers be bred for the first time?
Bulls can reach puberty by the time they are 8 months of age, but most are put in with the breeding herd by the time they are 12 months of age. Heifers reach puberty by the time they are 10 to 12 months of age, but most heifers are not bred until they are 15 months old. Of course the breed of the bulls and heifers depends on when they reach puberty and/or when they should be used for producing offspring.
Is every cow a girl?
Yes! Cows are mature female bovines that have given birth to at least two calves. Heifers are females who have not given birth at all during their lifetime, and first-calf heifers are heifers that have given birth to their first calf. Steers and bulls, on the other hand, are MALES. Steers are male bovines that have been castrated or neutered (some people like to refer to them as "castrated bulls"), and bulls are intact male bovines that have not been castrated and are used (or going to be used) for breeding purposes.
Is there a way I can use a bathroom scale to weigh my puppy?
First, weigh yourself holding the puppy. Put your puppy down and weigh yourself. Subtract the first measurement from the second measurement and you have your puppy's weight!
Does a cow go through puberty?
No, a heifer does. Cows are mature female bovines that have had at least two calves, and thus are females that have already been through puberty when they were heifers, before they had their first calf.
What are short bred cows or heifers?
Short bred cows or heifers are females that are in early gestation or pregnancy, mostly in their first trimester.
How many teats do mother cattle have?
Cows and first-calf heifers have four functional teats.

Do heifers lactate like cows do?
No. Heifers, being young female cattle, don't lactate until after they've had their first calf, which is typically at 24 months of age. A heifer remains a heifer, from birth, until she's had her first or second calf, whereby she is considered a cow. But until then, heifers don't lactate like cows do, and when they do lactate after birthing a calf, they typically produce less milk than their older counterparts.
Can you experience pelvic girdle pain in the first 2 weeks of pregnancy?
Yes
At what age does a calf have her first cycle?
Depending on the breed, generally most heifers begin to cycle at around 10 to 12 months of age. Some breeds have heifers begin cycling earlier, such as Jersey which begins cycling at around 7 months of age.
Who use the first standardized system of measurement?
The French and Germans used the first standardized system of measurement.
When do young heifers go into estrus for the first time?
There are a few factors involved, care of the animal will play a part. Typically it depends on maturity of the reproductive tract, but also on body condition and genetics. Most heifers will begin their initial cycling at around 11 to 12 months, however this is not always the case with breeds that are early maturing such as Jerseys, Dexter, Gelbvieh and Galloway, which may start coming into heat around 8 to 9 months of age. Late maturing breeds such as Brahman will find heifers going into first heat at 15 months. Other late maturing breeds like Charolias, Chianina and Limousin will have heifers going into their first eat between 13 and 15 months of age. Malnourished animals or those in poor body condition will have a delayed first estrus, but overly fat heifers will also come into heat for the first time later than those that are in normal condition. Genetics also play a role in determining the start of puberty for heifers. Some breeders select for cattle within a certain breed they're raising to be more early maturing than the breed average.
The hind limbs on a frog attach to the central skeleton by first attaching to the girdle?
pelvic
Is pelvic sonogram similar to ultrasound?
The first uses the second, so they are not really "similar".
Where on the cow is the sirlon?
The sirloin is the first section of the pelvic area of the cow, before the leg joint that joins the back leg to the pelvis. The other half of the pelvic area is called the round.
