Artificial variable temperature incubation method suitable for species bar-headed gooses endemic to Qinghai-Tibet Plateau

Abstract

The invention relates to the technical field of rare bird breeding, in particular to an artificial variable temperature incubation method suitable for species bar-headed gooses endemic to the Qinghai-Tibet Plateau. The method comprises the first step of preparation before incubation, wherein 1, an incubator and associated equipment are cleaned, disinfected and debugged, and 2, eggs are cleaned and disinfected; the second step of temperature and humidity control during incubation, wherein 1, the temperature is controlled, and 2, the humidity is controlled; the third step of management during incubation, wherein 1, the eggs are turned, 2, the eggs are candled, and 3, the eggs are cooled; and the fourth step of egg traying and hatching, wherein according to the incubation method, bar-headed goose hatching eggs are hatched 28 days after incubation, traying is carried out on normal embryo hatching eggs at the 26th day of incubation, and water at the temperature of 30 DEG C is sprayed 4-5 times every day to soften egg shells. The artificial variable temperature incubation method has the advantages of being reliable in principle, capable of improving the hatching egg hatching rate to 92-95% and suitable for being used and popularized in the Qinghai-Tibet Plateau and even the whole nation.

Description

technical field [0001] The invention relates to the technical field of rare poultry breeding, and more specifically relates to an artificial temperature-variable hatching method suitable for bar-headed goose, a unique species in the Qinghai-Tibet Plateau. Background technique [0002] At present, the bar-headed goose has become the new darling of the rare bird breeding industry, and is favored by more and more domestic breeding enterprises [1]. Wild bar-headed goose belongs to the second-class national protected animals. In my country, it mainly breeds and inhabits the Qinghai-Tibet Plateau, and is very adaptable to the harsh environment of the Qinghai-Tibet Plateau, especially the anoxic environment [2]. It is this unique physiological habit that determines the difficulty of artificial breeding and breeding of wild bar-headed geese. At present, domestic bar-headed goose breeding is still in its infancy [3]. Improving the artificial hatching rate of bar-headed geese is the...

Problems solved by technology

2. The text of the document has already mentioned that "due to the poor equipment conditions and the incubator, the temperature in the incubator actually varies between 36.4°C and 39°C, and the relative humidity varies between 45.7% and 52.1%", so it can be determined that in this article The low artificial hatching rate was caused by the high hatching temperature (39°C) caused by the use of discarded eggs and the crude equipment at that time. It cannot be inferred from this that the variable temperature hatching technology is not feasible

Therefore, the use of artificial constant temperature incubation is obviously unscientific, and it is difficult to truly guarantee the efficient hatching rate of bar-headed geese
