example 1

[0014] The invention discloses a method for inducing birth of Chinese giant salamander artificially, which consists of the following steps:

[0015] 1) Establish a small-scale outdoor breeding base next to the established giant salamander breeding base. The water temperature and quality in the small-scale outdoor breeding base should be consistent with the water temperature and quality in the established outdoor giant salamander breeding base;

[0016] 2) Put 100 giant salamander parents for breeding in the above-mentioned outdoor giant salamander breeding base and raise 10 pairs of giant salamander parents in the above-mentioned small-scale outdoor breeding base;

[0017] 3) When the number of giant salamander parents in the above-mentioned small-scale outdoor breeding base has naturally spawned to 3, immediately aphrodisiac the 100 giant salamander parents in the above-mentioned outdoor giant salamander breeding base until spawning.

example 2

[0019] The invention discloses a method for inducing birth of Chinese giant salamander artificially, which consists of the following steps:

[0020] 1) Establish a small-scale outdoor breeding base next to the established indoor giant salamander breeding base. The water temperature in the small-scale outdoor breeding base is inconsistent with the water temperature in the established indoor giant salamander breeding base;

[0021] 2) Put 100 giant salamander parents for breeding in the above-mentioned indoor giant salamander breeding base and raise 10 pairs of giant salamander parents in the above-mentioned small-scale outdoor breeding base;

[0022] 3) When the number of giant salamander parents in the above-mentioned small-scale outdoor breeding base naturally spawns to 5, immediately aphrodisiac the 100 giant salamander parents in the above-mentioned indoor giant salamander breeding base until spawning.

[0023] In this method, the principle of imitation ecology is used to a...

Abstract

The invention provides a hasten parturition method for artificially bred giant salamanders. The hasten parturition method comprises the following steps of establishing a small outdoor ecology-imitating breeding place according to the local climate of the giant salamander breeding place and natural conditions of water temperature and water quality; and promoting estrus on giant salamander parents in the corresponding breeding place according to conditions of spawning of the giant salamanders in the outdoor ecology-imitating breeding place, and enabling the giant salamanders to spawn. According to the hasten parturition method, the human and the nature are combined, an ecology imitation principle is utilized, the estrus promotion time of the giant salamanders in a year is accurately controlled by observation, the birth rate of the giant salamanders in the current year is increased by about 13%-17%, so that the yield is improved, the cost is reduced, and the income of farmers is increased.

Description

technical field [0001] The invention relates to the field of artificial reproduction of animals, in particular to a method for inducing labor in the artificial reproduction of giant salamanders. Background technique [0002] At present, there are many domestic farmers engaged in artificial breeding of giant salamanders, and the methods adopted are mostly: using drugs to aphrodisiac, so that the male and female giant salamanders mature synchronously, then artificially pull eggs, artificially collect sperm, fertilize, and then put them in still water or microcirculation water for incubation until germination. This method has the following difficulties: 1. It is difficult to determine the aphrodisiac time of male and female giant salamanders; 2. The ratio of aphrodisiac drugs used by male and female giant salamanders is difficult to control; The emergence rate is not ideal, generally only about 10% to 30%. [0003] Since the 1980s, some people in my country have started to ex...
