Introduction of Lande goose seedlings

The breeding of Lande Goose has stable fry production and high quality. Goose fatty liver is a very precious high-grade food, which is recognized as nourishing food, so it is also the ignorance of aquaculture.

Lande goose characteristics

Lande goose performance

1, spawn. Generally, the first year is 1 1, and May is the laying period. The average number of eggs laid is 30-40/year, and the egg weight is160-200g.

2. weight Adult male Luo 7-8 kg, adult female Luo 6-7 kg. The weight of 8-week-old goslings is about 4.5 kg, and the weight of fattened goslings is10-1kg. The average weight of fatty liver is 700-800g. Each feather can reach 350-450g when pulled twice.

3. Lande geese breed. Sexual maturity is 180 days. Generally, eggs are laid in 2 10 days, and the fertilization rate of eggs is about 80%. Female birds have strong nesting ability, and the survival rate of chicks is over 90%.

Feed and feed

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

4- 10 days old, you can feed it 6-8 times a day, including 2-3 times in the evening. When feeding green feed every day, you can add a proper amount of rice grains. If mixed feed is fed, the ration is 60-70% of green feed and 30-40% of compound feed.

1 1-20-day-old goslings should give priority to green feed, and the rice grains should transition to broken rice. If the compound feed is fed, the diet is 80-90% green feed and concentrate 10-20%, and it should be fed 6 times a day, including 2 times in the evening. If the weather is mild, you can start training grazing.

At the age of 2 1-30 days, add boiled grains to the diet appropriately, and gradually feed wet grains. When feeding meat, the proportion of diet is 90-92% of green feed and 8- 10% of concentrate, and it is fed five times a day, of which 1-2 times is in the evening. You can graze after 30 days of age, and you can supplement 1 times of concentrate at night. At present, the following standards are commonly used in concentrate formula: 0-3 weeks old, metabolic energy 12. 1MJ/kg, crude protein 20%, crude fiber 5.8%, lysine 1.0%, methionine and cystine 0.6%, calcium 0.65% and available phosphorus 0.4%. 4- 10 weeks old, metabolic 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% and salt 0.3%. Breeding geese, metabolic energy 1 1.7 joules/kg, crude protein 15.5%, fiber 6.2%, lysine 0.6%, laying geese, metabolic ship1.7 mj/kg, crude protein.

Temperature and humidity

The suitable growth temperature of gosling suspension is about 25 ″12. The temperature required for the brooding period can be adjusted according to the age of the day and the physical condition of the gosling.

In general, the brooding temperature of 1-5 days old is 27-28℃, the room temperature is 15- 18℃, and the relative humidity is 60-65%.

The brooding temperature of 6-40 days old is 25-26℃, the room temperature 15- 18℃, and the relative humidity is 60-65%.

1 1- 15-day-old chicks have a temperature of 22-24℃, a room temperature of 15℃ and a relative humidity of 65-70%.

16-20 days old brooding temperature 18-22℃, room temperature 15℃, and relative humidity 65-70%. Generally, the heat preservation period of goslings is 20-30 days old. After the heat preservation period, we should pay attention to cooling in time, which can enhance the physique of goslings.

density

When brooding at self-temperature, the feeding density is usually 1-5 days 22-25 /m2, 6- 10 days 20 /m2, 1- 15-20 /m2. 2 1-30 days old 5- 10/m2, 3 1-60 days old 4-5/m2, and over 60 days old 2-3. For large flocks of geese, it is advisable to divide them into many small flocks, with-100 geese in each flock, so as to avoid crushing goslings during piling.

Lighting management

Feeding broilers should be given the same low light intensity as broilers, as long as it does not affect feeding, generally 5 lux is appropriate. For backup breeding geese, natural light is enough, and it is best for breeding geese to give artificial light for a certain period of time under natural light conditions.

Timely grazing

Goslings can start grazing gradually in about 7 days, and in the north, they can start grazing in sunny places after 15-20 days. Grazing should be carried out when the weather is clear, the temperature is not lower than 15℃ and dew evaporates. When grazing for the first time, you can return to the brooding room in 20-30 minutes twice a day. After 20-30 days of age, you can graze all day. Before grazing every day, goslings should be fed from little to no, so that they can get used to eating grass. Goslings can't go into the water until their feathers grow. When the weather is warm, let the goslings swim by the water and gradually adapt to life in the water.

disease control

Always keep the goose house (including the sports ground) clean, frequently clean the ground and replace the padding skin, and clean the feeding trough and drinking fountains every day to keep the house clean, warm and dry. Goose houses (including sports grounds) should be disinfected regularly. At the age of 1 day, gosling plague serum was injected intramuscularly. 1-7 days, antibacterial drugs such as norfloxacin should be used to prevent bacterial infection, and vitamins, especially vitamin C and vitamin E, should be supplemented in drinking water for 3 days continuously, and some diuretics can be supplemented if conditions permit. 15-18-day-old gosling plague vaccine was injected intramuscularly. After 20 days of age, anti-coccidiosis drugs should be added to prevent coccidiosis. When the temperature changes greatly at ordinary times, drugs such as clearing away heat and detoxifying should be added to drinking water to prevent and treat respiratory diseases. Pay attention to dosage and course of treatment when taking medicine.
