Southern part of the province. Daozhou gray goose is produced in Daoxian County, which swims in Xiaoshui River. The central production area is Daoxian Pengba, Qingtang, Shouyan, Meihua, Xianglinpu, Baimadu, Yingjiang, Wanjiazhuang, Shangguan, Dongmen, Futang and other places along the Xiaoshui River and its main tributaries. It has been introduced into breeding by neighboring counties and cities such as Lanshan and Guangxi and Guangdong provinces.

In recent years, people have used goose as gifts and the habit of eating goose meat, especially the young people in Nanliu County of Yongzhou City use goose as the mascot for their engagements and weddings. Goose is essential for the Qingming Festival, festivals, and red and white wine feasts. Goose meat has become a special dish on the table of the people of Yongzhou.

Breeding situation editor

Daoxian has a history of more than 400 years of breeding Daozhou gray geese. It has the characteristics of fast growth, fresh meat, wide adaptability and high efficiency. Daozhou gray geese are all treasures. Goose meat has the effect of “nourishing yin and qi, warming bones and opening Jin”, foie gras has anti-cancer effects, and goose feathers are high-quality light industrial raw materials. In the late 1970s, it became the main variety of live geese exported to Hunan for foreign trade, and enjoyed a high reputation in Guangdong, Hong Kong and Macao [2].

Daoxian County has taken a series of measures to support the Daozhou gray goose industry to become bigger and stronger. It has established a Daozhou gray goose purification and rejuvenation base in more than 100 villages in 14 townships with river distribution in the county, focusing on the core group of Daozhou gray goose original species mainly in Zengjia Village, Yingjiang, and the expansion of Daozhou gray goose groups mainly in Xialiu, Hongjialei, and Leijiadong, Baimadu Town.

Body shape and appearance edit

Daozhou gray goose has a beautiful appearance, moderate individual, and the whole body feathers are basically gray, while the abdomen and the ventral surface of the neck are white with fluff, the mouth is black, and the feet (metatarsal, webbed) are withered yellow; the neck is short, the feet are short, the body is short, and the buttocks are round.

Breed characteristics edit

Daozhou gray goose has strong foraging ability, strong disease resistance, disease resistance and tolerance to coarse feeding, and grows rapidly. Weight 3.5-4 kg for 60-75 days old. 90-day-old male goose weighs 5 kg, and female goose weighs 4-4. 5 kg. The female goose starts laying at 270 days old, and lays 40 eggs annually 7 grams, laying 3-4 nests of eggs per year, and concentrated in late August to the end of March of the second year. The adult body weighs 4. 5 kg, and can be listed in about 70 days under extensive feeding conditions. Generally, the age of the mother goose to start laying is 210 to 240 days, and the ratio of male to female is 1:7 to 10. The egg laying period of the mother goose is from September to February to March of the following year. The annual egg production of the mother goose after laying is 50 to 60, with an average egg weight of 172.1 grams. The mother goose has a strong nesting property. Generally, 11 to 15 eggs are laid and the nest is hatched. Each egg laying year nests 3 to 4 times, and each nest can hold 10 to 15 eggs.

Daozhou gray geese like to forage, play in the water, and mate, so they can grow well in places with mild climate, flat terrain, abundant pasture, and slow flowing water. When Daozhou gray geese sit in their nests, the male geese always stay at the edge of the nest; when the female geese leave the nest for food, the male geese sit in the nest for the female goose. Therefore, people call it “couple goose” and “love goose”.

Three major technical edits of breeding

Daozhou gray goose is a local excellent breed in Hunan Province. Its appearance is “iron mouth, copper feet, gray back, white belly”. It has a beautiful body shape, tender meat, delicious and delicious. It has the advantages of fast growth, less grain consumption, easy feeding, high efficiency, wide adaptability, and stable genetic properties.

Daozhou gray goose likes to find food, play in the water, and mate. Therefore, it grows well in places with mild climate, flat terrain, abundant pasture, and slow flow of living water. The adult weighs about 4-5 kg. Under extensive feeding conditions, it can be listed in about 70 days. Generally, the laying age of a female goose is 210-240 days, and the ratio of male to female for breeding geese is 1: (7-10). The laying period of the female goose is from September of the current year to February-March of the following year. The annual egg production of the female goose is 50-60, and the average egg weight is 172.1g. The female goose has a strong nesting ability. Generally, 11-15 eggs can be nested and hatched. Each laying year nests 3-4 times, and each nest can hold 10-15 eggs.

The breeding of Dazhou gray geese mainly has the following three points.

(1) Feeding method

Generally, goslings can be fed after 24-30 hours of shelling. First cut the green material into thin filaments, and then sprinkle it evenly on a clean plastic film or cardboard in batches. Sprinkle as much as you eat, so that you can feed less and frequently, and be patient. Feed 4-5 times a day for 1-4 days of age, and 6-8 times a day for 4-10 days of age. Feed 1-2 times at night. At this time, the diet can be matched with 20% -30% broken rice or rice. After feeding, give 0. 1% -0. Drink 5% potassium permanganate solution to clean up the stomach and intestines. When it is hot, grazing starts at about 7 days old, and when it is cold, grazing can only be done after 10-20 days old.

When the geese are raised to more than 1 month old, grazing should be the main one, but some concentrates should also be fed according to their growth and development, the quality of pasture and the actual feed intake of the goose flock. Generally, each one is fed 50-150 grams per day. The concentrates are mainly rice, crushed corn, bran, etc., and 5% bone meal or shell powder, and about 0.3% table salt are added to the diet.

On the basis of feeding enough green materials, the geese should be properly replenished with concentrates before laying eggs to improve their weight and accumulate nutrients for egg laying. The essence of the male goose should be fed in advance, so that the female goose has plenty of energy for breeding before the start of production, so as to improve the fertilization rate.

The female goose in the egg-laying period is mainly fed in a house, supplemented by grazing. The ratio of the diet is roughly 2:1 between grain and coarse bran, or 62% of rice and 30% of coarse bran. Except for green feed, each goose is fed 90-150 grams per day. The feeding should be regularly and quantitatively, coarse first and then refined, and fed 2-3 times a day.

When production is stopped, grazing should be the main one, and coarse feed should be changed to facilitate reproduction and management. Coarse feeding makes the female goose not too fat, which is not only conducive to egg laying, but also cultivates the ability of the goose flock to tolerate coarse feeding, so that it can tolerate hunger during hatching. In addition, it can also reduce the cost of breeding.

(2) Thermal insulation and moisturizing

The body temperature of the newly hatched goslings is 2-3 degrees Celsius lower than that of the adult geese. At this stage, the focus is on heat preservation. The method is to use a tile-tube stove, thermal insulation umbrella, infrared rays, light bulbs, etc. Generally speaking, when using a greenhouse to brood, the indoor temperature is 30 degrees Celsius for 1 day of age. After that, the indoor temperature will be reduced by 1 degree Celsius every day, and it will be dewarmed at about 10 days of age. On the basis of heat preservation, pay attention to It is usually required to keep the relative humidity at about 65% at 1 week of age, 60% at 2 weeks of age, and about 55% after 3 weeks of age.

(3) Epidemic prevention and control

Inject 1 ml of gosling plague vaccine diluted 100 times 1 month before the goose lays eggs, and develop immunity 2 weeks after injection, or inject anti-gosling plague serum within 1 week of gosling shelling, and each subcutaneous injection is 0.5ml. If other diseases are found, they should be treated in time.
