The effect of dead or immotile sperm on the motility and fertility of the stronger sperm in bovine semen

The purpose of this Investigation was to determine what effect dead or immotile sperm have upon the progressively motile sperm in bull semen. From this information, it can be estimated whether or not substandard ejaculates can be mixed with the better ejaculates and still maintain a conception rate equal to that of the latter when it is used alone.
