EXTRACT FROM COURSE NOTES
The Technique of Artificial Insemination
There are two main parts to Artificial Insemination, namely:
  • collecting, diluting, freezing and packing the semen from the bull; and
  • thawing out and injecting the semen into the cow at the right time for conception.
With each ejaculation, a normal bull produces 7 - 10 millilitres of semen. Each millilitre contains one to one and half thousand million healthy sperm. After collection, the semen is diluted to five times the original volume using a solution called an extender. A typical extender consists of egg yolk, sodium citrate, antibiotics, dextrose and glycerol.
The diluted semen is packed into long, thin containers called straws. Each straw contains enough semen for one insemination. Every straw is labelled with the name and number of the bull and the date of packing. The straws are then deep frozen and stored in liquid nitrogen at a temperature of -142°C or in liquid nitrogen vapour at a temperature of -125°C. Although semen will freeze at any temperature below 0°C, it is safe from injury only when it is below - 40°C. to - 65°C. Freezing of sperm in N(l) also allows sperm to remain viable for 20 years or more after collection.
As the temperature rises above the safe zone, ice crystals in the semen will enlarge and move, causing damage to the sperm and reducing their viability. Once a straw has been thawed out it must be used at once or thrown away. Each straw contains 0.5ml or diluted semen. By using deep frozen semen, one bull can produce enough semen to inseminate 30 000 to 40 000 cows a year. Using natural service, one bull might serve 50 cows a year.
The semen is thawed out and deposited into the uterus of the cow using a special instrument consisting of a long plunger and a long, thin plastic tube. A cow is inseminated when she is ‘on heat’. The plastic tube must be passed through the cervix and the semen placed into the uterus so that it is available to fertilise the egg after ovulation has taken place. Insemination is a skilled process and should be carried out only by a trained operator. A good inseminator should achieve an 80% conception rate.
COURSE DURATION
100 hours; to be completed at your own pace according to how much time your situation allows.

How You Study
  • When you enroll, we send you an email that explains it all.
  • You are given a short orientation video to watch, where our principal introduces you to how the course works, and how you can access all sorts of support services
  • You are either given access to your course online, or sent a CD or course materials through the mail (or by courier).
  • You work through lessons one by one. Each lesson has at least four parts:
    • An aim -which tells you what you should be achieving in the lesson
    • Reading -notes written and regularly revised by our academic staff
    • Set Task(s) -These are practicals, research or other experiential learning tasks that strengthen and add to what you have been reading
    • Assignment -By answering questions, submitting them to a tutor, then getting feedback from the tutor, you confirm that you are on the right track, but more than that, you are guided to consider what you have been studying in different ways, broadening your perspective and reinforcing what you are learning about
    • Other - Your work in a course rarely stops at just the above four parts. Different courses and different students will need further learning experiences. Your set task or assignment may lead to other things, interacting with tutors or people in industry, reviewing additional reference materials or something else. We treat every student as an individual and supplement their learning needs as the occasion requires.
  • You are given access to and encouraged to use a range of supplementary services including an online student room, including online library; student bookshop, newsletters, social media etc.
  • You are provided with a "student manual" which you can refer to if and when needed. It provides a quick solution to most problems that might occur (some people never need to use this; but if you are studying late at night & have a problem, the manual provides a first port of call that can often get you moving again).
