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.
Seven milliliters per ejaculation.
One bull usually ejaculates around 7 mL of 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.
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.
No. Animal fats are used in cosmetics like hand lotion and soap, but never bull semen.
No, of course not!
There can be over a billion sperm in one 0.25 ml straw of bull semen.
You can collect semen from a bull around three times a day, although, more times can be done, however it's best to be wise about letting a bull getting his rest and not learn to get too discouraged about letting his semen getting collected for artificial insemination. At best, once or twice a day semen collection should be more than enough.
Sperm and semen production officially starts when they reach puberty, but bull calves can also start semen production even before they are born.
The average bull has around 1.2 billion spermatozoa per mL of semen ejaculated.
Bull semen must be kept frozen in liquid nitrogen to keep it for a long period of time, even after the bull has died.
anytime it wants
As many as what a breeder needs. Bulls don't produce semen that need to be collected like with cows that produce milk. A bull can fill thousands of straws per year if need be, depending on the demand for straws from that particular bull.
