Inyati a BSE exam will run at the least 150 bucks. Farm call alone is 75. My concern now is throwing good after bad. I have the microscopes and all, just no way to get the ejaculate.
Hook, the BSE does the following which I copied from a college research paper;
A BSE consists of three steps or parts:
1. A physical exam including the internal and
external reproductive structures.
2. A measurement of scrotal circumference; 30 cm is
the minimum acceptable size for even young bulls, and the
size requirement increases with age.
3. Collection and evaluation of semen. At least 30%
motility and 70% normal morphology are required as a
minimal acceptable level.
The standardized procedure of evaluation will result
in a classification into one of three categories:
a. “Satisfactory” potential breeder
b. “Unsatisfactory” potential breeder
c. “Classification Deferred” (with a recommended
date for re-evaluation)
I am surprised there is not a count piece of the puzzle, in other words number of spermatozoa per cc or other volumetric unit. But you got more to do than just look at the cells. You would have to know if their morphology is acceptable. Maybe I misunderstood you. You said you have a microscope (you will probably need oil immersion); are you planning on doing your own evaluation? You would have to get some training to properly evaluate the motility and morphology?
PS I think Number 1 and 3 above are important to your circumstances. First, looking at the internal anatomy of the reporductive apparatus is going to make sure there is not tissue damage that is physically going to prevent the bull from performing. Number 3 will tell you if the sperm being produced by the spermatogenesis process are normal/acceptable and thus capable of penetrating the pellilucida of the egg which is fundamental to the formation of the zygote.
