The invention discloses a sperm fluorescence staining method, which comprises the steps of: mixing sperms with PI, Transgreen and Transgreen / PI, and putting the mixture into an incubator with 5 percent CO2 and temperature of 37 DEG C for cultivation. Applying a computer to assist a sperm and semen quality analysis system and analyze changes of all movement parameters of sperms after adding fluorescent dye and Transgreen / PI redyeing is feasible for calculating the survival rate of sperms.

A method for measuring the total sperm concentration (TSC) in a sample is described and includes: (i) placing the sample in a transparent container between a synchronically pulsed light source and a photodetector; and (ii) measuring the optical absorbance of the sample in the range of 800-1000 nm, the TSC of the sample being proportional to the absorbance. Also described is a sampling device for use in optically analyzing a biological fluid, a method for measuring motile sperm concentration (MSC) in a semen sample, a method of determining the average velocity (AV) of sperm cells and a system for analyzing semen quality including means for measuring TSC, means for measuring MSC; and a video visualization system.

The present invention relates to the field of breeding boar feed, and provides functional feed and mixed batch for alleviating heat stress of breeding boars.

The invention relates to a pig semen normal temperature liquid negative pressure preservation device which comprises a closed container, a rubber plug, a connecting tube, a vacuum pump and a semen preservation tube, wherein the rubber plug is arranged at the upper part of the closed container; one end of the connecting tube penetrates through the rubber plug and extends into the inside of the closed container, and the other end of the connecting tube is connected with the vacuum pump; the semen preservation tube is arranged at the bottom inside the closed container. The invention further relates to a method for preserving pig semen by utilizing the device. The method comprises the following steps: removing upper seminal plasma of the fresh pig semen through a centrifugal machine and then diluting the upper seminal plasma with a diluent. The semen preservation tube is put in the closed container, and the closed container is covered with the rubber plug with a valve, and the connecting tube is connected with the vacuum pump with a vacuum meter; the vacuum pump is started to pump air out of the closed container. The pig semen normal temperature liquid negative pressure preservation device provided by the invention has the benefit that as the pig semen is subjected to normal temperature liquid preservation by using the device, the preservation time can be prolonged to 9-13 days, so that the sperm and semen quality are significantly improved.

The invention discloses an artificial insemination device for goats. The device comprises a square frame, goat fixing devices are fixed to four lateral sides of the square frame respectively, the upper end of each goat fixing device is hinged to the top of the square frame, the middle of each goat fixing device is hinged to a telescopic ejection rod of an electric hydraulic jacking mechanism in the square frame, and goat limb binding devices are arranged outside the goat fixing devices respectively. By adoption of the goat fixing devices for fixing female goats and adoption of the electric hydraulic jacking mechanisms for adjusting heights of the goat fixing devices, artificial insemination operations are facilitated, fixing operation only requires one person to fix to-be-inseminated female goats to the goat fixing devices without assistance of other people, and accordingly manpower is greatly saved, operation efficiency is improved, and semen quality decline caused by time delay is avoided.
