The natural breeding efficiency of cattle is low, and there is a need to breed too many cattle. Now artificial insemination is generally used. Recently, the reporter interviewed members of the Expert Advisory Group of the newspaper and Professor Lin Qing of Animal Science and Technology College of Northwest Agriculture and Forestry University.
Breeding cows requires only a few cattle per farm, and the breeders usually choose good breeds, have a good temperament, and must ensure frequent replacement. Breeding cattle must be very fine. When feeding concentrates and grasses, certain eggs, fruits and sugar must be matched. And often have to do a kind of physical inspection of cattle, to ensure the health and bred cattle.
Artificial sperm extracts need to be cleaned first, using saline, distilled water, 75% alcohol. Put the rubber sleeve flat on the sperm tube and clean it more than 3 times. When the sperm is collected, the extraction tube is heated to about 38° C., the estrus cow is fixed in the column, and when the bull is crossed, the manual collection device is used to collect sperm. When collecting sperm, attention should be paid to the personal safety of the operator. After the sperm is collected, the activity is observed under a microscope. After confirming that the sperm activity is good, it can be diluted with distilled water, and tubed and sealed.
Artificial insemination sealed the tube of frozen sperm into warm water at 40°C for thawing, and then examined under the microscope. Insemination can be performed without any problem. The gloved hand is held in a tapered shape and penetrated into the rectum of estrus cows under the paraffin oil lubrication to help the cows discharge the stool. The deeper part of the rectum is pulled deeper into the uterine horn to check the ovaries and uterus. The cervix, with the cervix gently sliding, stimulates cows to become excited. The estrus-producing healthy cows will have egg-like mucous from the vaginal discharge, according to the mucus traits can determine whether there is uterine disorders, estrus conditions. At this point the need for professional tools such as insemination guns, and professional insemination operations.
