Determination method of giant panda estradiol true peak value

Abstract

The invention discloses a determination method of a giant panda estradiol true peak value. According to the invention, urine samples of female giant pandas at a spring breeding period are collected and are subjected to chemical analysis; conditions such as a time for an estradiol maximal peak or a subsequent estradiol peak to decrease with an amplitude reaching a value above 50%, whether a progesterone value is in an increasing trend during the decreasing period of the estradiol maximal peak or the subsequent estradiol peak, whether the giant pandas show a typical estrous peak behavior, and a ratio of the corresponding progesterone value of the estradiol maximal peak or the subsequent estradiol peak to a progesterone basic value are combined, and the giant panda estradiol true peak value is determined. The method provided by the invention is obtained on the basis of statistical analysis of estradiol variation regularities of 78 oestrus giant pandas which constructs a maximal datum quantity currently, such that the method has high reliability. The method assists in filling up a giant panda research vacancy, and provides a scientific basis for improving captive giant panda artificial insemination conception rate.

Description

technical field [0001] The invention relates to a judging basis for timely artificial insemination of captive animals, in particular to a judging method for the true peak value of estradiol in 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. The natural mating ratio of giant pandas is relatively low. At present, only about 50% of giant pandas are able to mate naturally, and about half of the giant pandas need to be reproduced through artificial insemination. [0003] Before the mid-1990s, judging the timely mating timing of giant pandas was mainly based on the qualitative observation of giant panda estrous behavior, and the timing of giant panda mating was determined based on experience, resulting in unclear timing of timely artificial insemination of giant pand...
