Vasectomy and birth control in deer

Vasectomy can not only prevent birth control by blocking sperm output, but also does not affect the libido and antler production performance of male deer. Now the relevant situation of the operation is summarized below.

1 preoperative preparation

1.1 A small amount of digestible feed should be fed the night before the operation, but not in the next morning, and the operation should be carried out in the morning or morning.

1.2 Anesthesia in order to enhance the anesthetic effect, the dosage of Mianailing can be increased by 1.5 × 2 per deer intramuscularly.

1.3 the operation was scrubbed, shaved, dried and disinfected. The operation is located on the anterior or posterior side of the upper scrotum.

2Surgical process

2.1Longitudinal incision of the skin 2~3cm, then blunt stripping of the subcutaneous tissue and muscle, and finally cutting off the total sheath to expose the spermatic cord.

2.2 pull the spermatic cord out of the incision, cut open the inherent sheath and find out the vas deferens. The vas deferens of the deer are white and hard, with a diameter of about 1~2mm.

2.3.To make two ligation of the vas deferens apart from 1.5~2cm, resect the 1cm of the vas deferens between the two ligation and stop the bleeding.

2.4 rinse the operation with saline mixed with antibiotics, then send it to the scrotum and spread antibiotics through the incision.

2.5 full-layer nodule suture incision, suture the skin, muscle and sheath together, tidy up the wound margin, and apply iodine tincture to the operation.

3 postoperative nursing

3.1 fasting for the first 2 days after operation, but free to drink electrolytic multi-dimensional water, then fed with a small amount of digestible green feed and concentrate feed every day, and returned to normal after 4 days.

3.2 keep the environment clean and quiet, especially to prevent the operation department from being contaminated by dirt and sewage when lying on the ground.

3.3 during the first 3 to 5 days after operation, antibiotics were used all over the body to prevent infection. Stitches were removed after the incision healed completely.

4 results

4.1 in the first 2-3 days after operation, the male deer showed depression and loss of appetite, and the operative part was slightly swollen, then gradually returned to normal, and the stitches were healed and removed in 7-10 days.

4.2 the antler production performance and libido of deer were normal, and there was no adverse effect.

5 discussion

5.1 vasectomy and birth control is an ideal way to turn an eliminated buck into an experimental buck. The male deer not only has normal sexual desire and antler production performance, but also can climb across the estrus female deer, but can not make the female deer fertilize and become pregnant, so the estrus female deer can be found in time for artificial insemination.

5.2 the operation has the advantages of small incision, little injury, easy to recover, simple, rapid and easy to popularize.

5.3 the birth control effect of vasectomy is indeed better than that of simple vasectomy, which is caused by simple vasectomy, loosening of vasectomy or too long time, corrosion and degeneration of ligation line, which leads to the failure of birth control due to the re-connection of vas deferens.
