The trial of artificial insemination in deer

Trial is a way to let the male deer get in touch with the female deer within a certain period of time to determine whether the female deer accepts climbing (but not to allow the female deer to actually climb across the mating) to determine whether the female deer is in estrus and to determine the specific time of insemination. Whether the test is accurate or not plays an important role in improving the quasi-pregnancy rate of female deer.

I. the choice of trial deer

The trial deer must choose a young, healthy, docile and libido male deer. In general, male deer with large testes secrete more androgens and exuberant libido, so they should pay more attention to observation and attention in order to choose trial deer in the future.

Second, try the lazy way

1. From August 2002 to now, a small incision of 3 cm was made in the posterior epididymis of 5 male deer, and the vasectomy was performed on both sides of the epididymis of 5 male deer. After 3 years of effect observation, it has a certain influence on its libido, and the effect of emotion test is general.

two。 From August 2002 to now, 3 penises of 7 male deer have been shifted 60 degrees to the right in 4 to the left. As a result of the 3-year trial, he maintained a strong desire for mating during the trial, but he could not really mate when he climbed the leap, and the effect was very good.

3. The special trial deer selects deer with relatively short hind limbs to train the test situation in the healthy production male deer herd. The climbing ability of such deer is normal, but the mating ability is poor. During the trial situation, the trial staff should be seriously responsible and set aside the test deer in time.

Third, trial time

There are four trials every day: 5 ∶ 00 in the morning, 10 ∶ 30 in the morning, 4 ∶ 30 in the afternoon, and 9 ∶ 30 in the evening. The duration of each trial is not less than 20 minutes.

IV. Emotional testers

The examiners are required to be careful, bold, responsible and record carefully. When the trial deer is found to climb across the doe and the doe stands still, it is necessary to timely set aside the estrus deer, separate the estrus doe, and report it to the insemination staff in time to determine the specific time of insemination.
