Problems solved by technology

[0009] Although there are more cases in the latter two reports, and the relationship between the timing of natural mating and artificial insemination and litter success was proposed, the biggest problem in the two reports is that neither of the two authors compared artificial insemination with natural mating. separate
Since natural mating does not require anesthesia, it has little impact on ovulation, while artificial insemination needs to be performed under anesthesia. If the timing of artificial insemination is improper, it will have a greater impact on ovulation. If artificial insemination and natural mating are combined The timely breeding timing proposed by the mixed statistics of different breeding methods cannot truly reflect the reasonable timing, and there is also a lack of follow-up application and success rate reports to prove it
[0010] The main problem of current technology: In terms of technology to improve the success rate of natural mating of giant pandas, there is no mature technology at present, and the reasons for affecting the success of natural mating of giant pandas are not yet clear. Insufficient natural mating success data to support

Embodiment 1

[0052] According to the patent application number 201210191762.5, the present invention firstly collects urine samples from female giant pandas according to time requirements during the spring breeding period, and uses enzyme-linked immunosorbent assay to detect the real peak value of estradiol in female giant pandas and its appearance. time, such as figure 1 As shown, the change curve of the female giant panda's estradiol value and progesterone value is drawn, and the real peak coordinate point A of estradiol is obtained. Then take the time at coordinate point A as the starting point of time 0 hours, use the canine luteinizing hormone kit of Shanghai Byward Biotechnology Co., Ltd., and use enzyme-linked immunosorbent assay to detect the LH value of all urine samples from 0 hours to 48 hours; The urination time of the female giant panda is taken as the abscissa, and the LH value is taken as the ordinate. figure 1 Mark the coordinate points determined by the urination time and...

Abstract

The invention discloses a method for timely releasing panda pairs to allow natural mating. The method includes: accurately detecting LH (luteinizing hormone) peak and emergence time in female pandas according to true estradiol peak and emergency time thereof in female pandas; arranging normally ovulating female panda individuals for primary natural mating in 16-30 hours after the time of true estradiol peak according to such conditions as true estradiol peak, time intervals between LH peak and true estradiol peak, and whether the female pandas are in heat peak synchronously or not; arranging ovulation-delayed female panda individuals for primary natural mating in 16-30 hours after the time of true estradiol peak; and allowing for single or multiple times of natural mating. The period of primary natural mating is shortened from 48 hours to present 20 hours, success rate of natural mating in panda is increased from the traditional 21.05% to 46.15% finally, and the success rate is more than doubled.

Description

technical field [0001] The invention relates to a method for timely natural mating of captive animals, in particular to a method for timely pairing of giant pandas for natural mating. Background technique [0002] The low natural mating ratio of giant pandas has always been an important factor affecting the successful reproduction of giant pandas. According to statistics, from 1936 to 1989, a total of 41 giant pandas were raised in captivity in 41 zoos, research institutions and nature reserves at home and abroad. The number exceeds 240, but there are few male giant pandas with natural mating ability; Hu Jinchu. 1990. Giant Panda Biology Research and Progress. Chengdu: Sichuan Science and Technology Press. p316, there are 8 in total during this period Male giant pandas have the ability to mate naturally, accounting for only 7% of the total number of captive male giant pandas. [0003] Feng Wenhe, Zhang Anju, etc. 1997. Effects of different mating methods on giant panda litt...
