There can be over a billion sperm in one 0.25 ml straw of bull semen.
You get the sperm by the straw. And the amount per straw depends on the quality of the bull, how large the demand is for that bull as well as the breed of such a bull. Prices for semen straws can sky rocket if the bull dies and there is only a limited quantity of semen left. You will have to check your local bull semen distributor or any other cattle ranches that sell bull semen for their prices.
Bull semen must be kept frozen in liquid nitrogen to keep it for a long period of time, even after the bull has died.
A straw is .5 ml or .25 ml
Through the use of artificial insemination. A straw of semen that was collected from a bull and frozen in a semen tank is inserted into the cow's vagina and into the cervix by a AI gun that holds the semen straw. One hand has to be inside the cow's anus to hold the cervix so the straw can go through, and the other hand has to be manipulating the straw into the uterus of the cow. Once the straw is in a little ways into the uterine cavity, the semen is deposited and the gun with drawn and the empty straw discarded.
It depends on the breed, the demand/supply for that particular bull, and whether that bull is a proven sire or not. Straws can go for as little as $10 per straw, and others can go as high as $200 per straw.
The average bull has around 1.2 billion spermatozoa per mL of semen ejaculated.
Sperm and semen production officially starts when they reach puberty, but bull calves can also start semen production even before they are born.
it lives out of the semen tank up to 15 minutes because of the dramatic temperature drop. so be quick with your transfers!!!
bull
One ejaculation, which is from 4 to 7 cc of semen. This is then, if used and stored for AI, is divided up into straws according to what each straw should hold. Usually, each straw will hold around 0.5 cc to 1.5 cc of semen.
I believe you are asking where you can acquire a straw of bull semen for artificial insemination. There are several reputable bovine AI companies that you can purchase the straw from; you can Google them under the search term "bovine AI".
As he said below. First, no reason to put it in there. Second- you obviously have no idea what high quality bull semen (used by farmers for artificial insemination of cattle) sells for. It is NOT cheap! It can be several hundred dollars per unit. You need to work on becoming less gullible.
