Embodiment Construction

[0100] The present invention observes the vulva color of female giant pandas every day during the estrus period of spring giant pandas. Redness and swelling of giant panda vulvas is the characteristic performance of giant panda estrus initiation. Panda estrus behavior, if there is frequent marking behavior and bleating behavior, it can be determined that the giant panda is in estrus.

[0101] After the giant pandas are in estrus, start to collect the urine samples of the female giant pandas, record the names of the pandas, the time of urination, and whether there is a typical estrus peak behavior on the urine samples, and conduct laboratory analysis on the collected giant panda urine samples in a timely manner. Use enzyme-linked immunosorbent assay to detect the estradiol and progesterone values ​​corresponding to the giant panda's name and urination time; at first, collect 1 morning urine every day; after the 4th day after the estradiol value continues to rise, collect 3 copie...

Abstract

The invention discloses a timely artificial insemination method for a giant panda. The method comprises the steps of: collecting, testing and analyzing urine samples of female giant pandas during oestrus in spring, simultaneously combining with these circumstances such as time that the drop of an estradiol maximal peak value or an estradiol peak value reaches up to over 50%, the condition whether a progesterone value is on the rise and the giant panda generates a typical heat peak behavior in the process of the estradiol dropping from the maximal peak value or subsequent peak value, and the ratio of the progesterone value corresponding to the estradiol maximal peak value or subsequent estradiol peak value to the progesterone basic value, judging a real peak value of the estradiol of the giant panda; then carrying out artificial insemination for the first time within 24-48 hours after the moment when the estradiol real peak value appears, and carrying out artificial insemination for the second time after 6-8 hours after finishing the artificial insemination for the second time, finally obviously improving the pregnancy rate of the giant panda. Compared with the past, the artificial insemination pregnancy rate of the giant panda is improved to 42.11% from 20.41% and is more than doubled.

Description

technical field [0001] The invention relates to a technology for artificial insemination of captive animals, in particular to a timely artificial insemination method for giant pandas. Background technique [0002] The giant panda is a rare and endangered wild animal unique to my country. Its own reproductive capacity is relatively low. The female giant panda only has one estrus period a year, and only 1 to 3 days in a estrus period can accept natural mating, and its ovulation time may only be one day; at the same time The natural mating ratio of captive giant pandas is relatively low. At present, only about 50% of the giant pandas can mate naturally, and about half of the giant pandas need to reproduce through artificial insemination. Since the artificial insemination of giant pandas needs to be carried out under anesthesia, according to the existing data According to the data, anesthesia before ovulation will lead to ovulation inhibition and ovulation delay in animals. If art...
