The breeding of Lande geese has stable and high-quality seedling production. Foie gras is a very valuable high-end food and is recognized as a nutritious delicacy, so it is also a favorite in the breeding industry.

Lande goose characteristics

Lande goose performance

1. Egg laying. Generally, the laying period is from November to May of the first year. The average egg production is 30-40 eggs per year, and the egg weight is 160-200g.

2. Weight. An adult male weighs 7-8 kg, and an adult female weighs 6-7 kg. The weight of 8-week-old goose is about 4.5 kilograms, and the weight of meat goose after filling is 10-11 kilograms. The average weight of fatty liver is 700-800 grams. Each down weighs 350-450 grams after being plucked twice.

3. Lande goose breeding. Sexual maturity period is 180 days. Generally, production starts in 210 days, the fertilization rate of hatching eggs is around 80%, the mother has strong nesting ability, and the survival rate of chicks is above 90%.

Feed and Feeding

Goslings eat less food when they are 1-3 days old and are fed 4-5 times a day, including once at night. In the future, as the age increases, the frequency and quantity of feeding will also increase accordingly.

4-10 days old, it can be fed 6-8 times a day, including 2-3 times at night. When feeding green feed every day, an appropriate amount of rice grains can be added. If you feed mixed feed, the dietary mix ratio is 60-70 parts green feed and 30-40 parts compound feed.

11-20-day-old goslings should mainly eat green feed, and transition from rice grains to broken rice. If they are fed compound feed, the dietary ratio is 80-90 parts green feed and 10-20 part concentrate. , fed 6 times a day, including 2 times at night. If the weather is mild, you can start training for grazing.

At 21-30 days of age, cooked grains can be added to the diet and wet grains can be gradually added. When feeding pigs, the dietary ratio is 90-92% green feed and 8-10% concentrate. Feed 5 times a day, including 1-2 times at night. After 30 days of age, they can be grazed and fed with concentrate once in the evening. Currently, the following standards are commonly used for formulating concentrates: 0-3 weeks old, metabolizable energy 12.1 MJ/kg, crude protein 20, crude fiber 5.8, lysine 1.0, methionine and cystine 0.6, calcium 0.65, available phosphorus 0.4, Salt 0.3; 4-10 weeks old, metabolizable energy 12.6 MJ/kg, crude protein 16, crude fiber 7.3, lysine 0.85, methionine and cystine 0.5, calcium 0.60, available phosphorus 0.4, salt 0.3; breeding goose, Metabolizable energy 11.7 J/kg, crude protein 15.5, fiber 6.2, lysine 0.6, egg goose, metabolic energy 11.7 MJ/kg, crude protein 15.5, crude fiber 6.2, lysine 0.6, methionine and cystine 0.5, Calcium 2.25, available phosphorus 0.40, salt 0.3.

Temperature and Humidity

The suitable growth temperature for goslings is about 25''12. The temperature required during the chick period can be adjusted according to the age and physical condition of the goslings.

Generally, the brooding temperature for 1-5 day-old chicks is 27-28°C, room temperature 15-18°C, and relative humidity 60-65;

The brooding temperature for 6-40 day-old chicks The brooding temperature for 11-15-day-old chicks is 22-24°C, the room temperature is 15°C, and the relative humidity is 65-70;

The brooding temperature for 16-20-day-old chicks is 18-22°C, the room temperature is 15°C, and the relative humidity is 65-70. Generally, the insulation period of goslings is 20-30 days old. After the insulation period, timely dewarming can enhance the goose's physical condition.

Density

In self-warming brooding, the usual breeding density is 22-25 birds/square meter for 1-5 days old, and 20 birds/square meter for 6-10 days old, using a stove. Or when brooding underground, 15-20 birds/square meter at 1-10 days old, 10-15 birds/square meter at 11-20 days old, 5-10 birds/square meter at 21-30 days old, 5-10 birds/square meter at 31-60 days old 4-5 birds/square meter when old, 2-3 birds/square meter over 60 days old.

For geese raised in large groups, they should be divided into many small groups, each group should have 100 geese, so as to avoid crushing and injuring the goslings when they are piled.

Lighting management

Like broiler chickens, raising broiler geese should be provided with low light intensity, as long as it does not affect food intake, generally 5 lux is appropriate. . For reserve breeding geese, natural lighting is enough, while breeding geese are best given artificial lighting for a certain period of time under natural lighting.

Grazing at the right time

Goslings can gradually start grazing when they are about 7 days old. In the north, they can start grazing in sunny places after 15-20 days of age. The grazing should be done in sunny weather and the temperature is high. It should not be lower than 15℃, and it should be placed after the dew evaporates. When grazing for the first time, you can rush back to the brooding room in 20-30 minutes, twice a day. After 20-30 days of age, they can be grazed all day long. Goslings should be fed from little to nothing before grazing every day to make them accustomed to eating green grass. The goslings should be raised until their feathers grow before they can go into the water. In warm weather, the goslings should be allowed to play by the water first and gradually adapt to life in the water.

Disease Prevention

It is necessary to keep the goose house (including the sports ground) clean and sanitary, clean the place frequently and replace the bedding. Feeding troughs and drinking fountains should be cleaned every day to keep the house clean. , keep warm and dry. Goose houses (including sports grounds) must be disinfected regularly. Gosling plague serum was injected intramuscularly at 1 day of age. Antibacterial drugs such as norfloxacin should be used to prevent bacterial infections from 1 to 7 days old. The drinking water should be supplemented with multiple vitamins, especially vitamin C and vitamin E. Use it for 3 days in a row. If possible, some diuretics can be added. Gosling plague vaccine is administered intramuscularly between 15 and 18 days of age. After 20 days of age, the anti-coccidial drug Keqiu Jingchi should be added to the feed to prevent coccidiosis. Usually when the temperature changes greatly, drugs such as heat-clearing and detoxifying agents should be added to drinking water to prevent and treat respiratory diseases. When using drugs, pay attention to the dosage and duration of treatment.
