Principle

|
-
Sperm progressive motility : % sperm those are motile in a straight line under their own power
-
Most important test: No. of motile sperm inseminated is highly correlated with fertility
-
Range in fresh ejaculates: 0 to 80%
-
Use multiples of 10% in reporting motility because of its subjective measurement
-
Ejaculates with initial motilities of 50 to 80%: little different in fertility level, if desired no. of motile sperm are present at insemination
-
Semen with less than 40% initial motility: not suitable to use, if not from exceptionally superior bull
