Semen collection method used for crested ibis

Abstract

The invention discloses a semen collection method used for crested ibis. The method includes step (1) of stopping water and feed supply: stopping water and feed supply 3-4 hours before semen collection; step (2) of disinfecting: gently lifting the tail of the crested ibis to expose the cloaca, and using cotton balls with 70% alcohol to wipe and disinfect the periphery of the cloaca of the crestedibis, rinsing the periphery of the cloaca with normal saline, and collecting semen after micro-dry; step (3) of collecting semen: restraining the crested ibis well, and gently inserting an electrode bar into the cloaca of the crested ibis to collect semen by electric stimulation. By adoption of the semen collection method, the semen of the crested ibis can be collected successfully, the operationis simple and quick, the semen can be collected repeatedly, and the crested ibis is not harmed.

Description

technical field [0001] The invention belongs to the technical field of captive animal artificial insemination, and in particular relates to a semen collection method for crested ibis. Background technique [0002] The crested ibis is a national Class I key protected bird and one of the most endangered birds in the world. Due to the gradual reduction of the natural habitat area and the deterioration of the environment, the viability and fecundity of the crested ibises have declined, and the population has declined sharply. Since the crested ibises all over the world were bred from 7 wild crested ibises rediscovered in Yangxian County, Shaanxi Province in 1981, this species Inbreeding is serious and the genetic structure is unreasonable. Crested ibis has become the species with the lowest genetic diversity among endangered birds in the world. Therefore, in the breeding process of crested ibises, a reasonable pair breeding plan and artificial insemination technology should be...

Problems solved by technology

This patent avoids that in the prior art, only male fish can be killed to extract sperm, the number of broodstock is consumed, the cost is high, and the operation is time-consuming and laborious, the effect is not high, and the survival time of the sperm taken from male fish is short, which directly affects the fry. Fertilization rate, parental injuries are more serious after female fish is squeezed to retrieve eggs, a large number of deaths often occur, and even some female fish cannot be used as parents in the next year, and the utilization rate of parents is greatly reduced.

Although fish also have a cloaca, as lower aquatic animals, the body structure and reaction mechanism of fish are very different from those of birds. Therefore, the method of this patent is not suitable for sperm collection in birds
