Semen Production, Packaging, Storage and Distribution Unit
NAGRC&DB collects semen from high quality bulls, the semen is subjected to both macroscopic and microscopic examination, the concentration of sperm in the sample is the then determined using a photometer, the ejaculate is then diluted using extenders that has different components that protect and increase longitivity of the semen, and later the semen sample is placed in the fridge at 4c for Equilibration which takes about 2 hours.
NAGRC also have an integrated semen packing machine which is also at 4c to fills, seals, straw and prints the bull identification on the straw, the straws are then racked and subjected to a freezing process which takes about 7 to 9 minutes, after the freezing the straws are @ -130c, then got out of the freezing Chambers into the semen bank which is @ -196c
Later, the semen is then subjected to post thaw microscopic examination, and quarantined for one month as the bulls are monitored for any disease outbreak, after this period the semen is cleared for use in Artificial insemination
