【Changtu Pastoral Song】 On the necessity of carrying out the work of preserving the seeds of Changtu Open Goose

1. The Changtu goose has unique economic characteristics

The reproductive performance of the Changtu goose ranks first in the world, known as the "national treasure", the complete protection and storage of the genetic resources of the goose can provide precious materials for the future hybrid production of different purposes of the goose industry and the cultivation of new varieties, which should be valued and protected.

2. Changtu Huo goose has broad application prospects

Although the current direction of goose products is still dominated by goose meat and down, and people one-sidedly pursue the body characteristics of geese, it does not mean that the historical mission of the goose has ended. The purebred Changtu goose has been snubbed, mainly caused by people's misunderstanding of the goose.

In fact, as a local fine breed, The Changtuhuo goose is completely suitable for the majority of farmers to scatter breeding, extensive breeding as the main production mode.

First, the fertility of the Changtuhuo goose is much higher than that of foreign species such as lai fungus goose and Langde goose, and the number of commercial goose meat and goose down provided by the unit breed goose is large, and the breeding cost of breeding geese is low.

Second, there is a certain gap between the Changtuhuo goose in terms of weight, fattening degree and feed remuneration and the imported high-yield meat goose species such as Lai fungus goose and Langde goose. However, with the continuous improvement of the living standards of the people in our country, the consumption concept of the masses, especially urban residents, has undergone an essential change, and the pursuit of quality, emphasis on flavor, healthy consumption, and return to nature have gradually become the mainstream of the development of the livestock products market. Changtu Huo goose this place of good breeds resistant to rough feeding, wide adaptability, strong disease resistance, suitable for free range, early production speed, high feed remuneration, very suitable for 70 days old rapid fattening of meat goose production, and good meat quality, delicious taste, more competitive in the market, will gradually become a sought-after goods.

Third, the Changtuhuo goose originates from the relatively cold northern Liaoning region, and the down quality is good, which is an ideal breed for the production of goose down. In the finished goose down exported by China, 1/3 of the northeast goose down must be mixed to meet the standard.

Fourth, breeding Changtu huo goose, low seedling price, high survival rate, less cost input, small risk, compared with foreign breeding varieties, strong adaptability, strong disease resistance, less medication, is the production of green goose products preferred varieties, suitable for the majority of agricultural areas to raise, farmers will not fall into the trap of frying seeds, for the steady development of the goose industry to play a positive role in promoting.

3. The survival status of the Changtu goose is not optimistic

Changtuhuo goose is widely used as the mother of economic hybridization everywhere, producing commercial meat goose seedlings, and some take Changtuhuo goose as the basic breed, and use foreign large and medium-sized meat goose varieties for progressive hybridization, trying to cultivate new varieties of meat goose. However, these hybridization and improvement are blind and utilitarian, especially under the condition that the protection ability of the Changtuhuo goose species is quite weak, the survival status and situation of the Changtuhuo goose are worrying, so it is recommended that the relevant departments at all levels of the state increase the protection of the resources of the Changtuhuo goose breed, otherwise, once the resources of the Changtuhuo goose species are lost, they will not be able to make up.
