Detecting and counting diluter for bull semen density

The invention relates to a detecting and counting diluter for bull semen density, which aims to solve the problems that a dropper for diluting and sucking semen and sodium chloride is a dropper with one end used for sucking, which needs to absorb semen and sodium chloride, and will cause the semen at the end of the dropper to be easily mixed with the sodium chloride solution not yet sucked when sucking the sodium chloride, and at the same time, because the diameter of the dropper is very small, there is not enough space for full mixing. The invention comprises a dropper body (1), wherein both ends of the dropper body are respectively inserted with an airbag body (2) for controlling the dropper body to suck liquid; the dropper body comprises a straight pipe section (12), and two ends of the straight pipe section are respectively provided with a tapered pipe section (11); the dropper body is provided with scales (13) which gradually increases from the tapered pipe section to the straight pipe section. The invention is used for dilution in bull semen density detection.
