1. Selection of goslings: It is appropriate for goslings to have big eyes, loud calls, fast reaction speed and bright coat color. 2. Tidal opening and food opening: Tidal opening is carried out before food opening, and 0. 1% potassium permanganate can be added to drinking water. 24-36 hours after taking out the shell, the food is cooked, and the food is selected from steamed millet and chopped green leafy vegetables or tender grass leaves. 3. Feeding: 1-3-day-old goslings are fed 4-5 times a day and 2 times at night. 5- 10-day-old goslings were fed 6 times a day and 2 times a night. 1 1-20-day-old goslings are fed 4-5 times a day and 1 time at night.
First, the culture technology of lion-headed goose
1, feeding technology of goslings
(1) gosling selection
After hatching, goslings have strong vitality, big eyes, loud cries, fast reaction speed and bright coat color. It is wise to contract your feet quickly when lifting your neck.
(2) Tidal mouth and food opening
(1) Start eating about 24-36 hours after hatching. The first food to eat is steamed millet, which is suitable for matching shredded green leaves or tender grass leaves. When eating, spread the food evenly on the plastic mat and let the goslings eat by themselves.
(2) Before eating, you need to drink water first, which is the tide mouth. Tidal water should be clean and hygienic, and 0. 1% potassium permanganate can be added to tidal water, which can effectively prevent intestinal diseases.
(3) Feeding
① The goslings mainly used rice in the first three days, and then gradually added compound feed. After 7 days, they were fed with compound feed instead.
② 1-3-day-old goslings were fed 4-5 times a day and 2 times at night until they were 7-80% full. 5- 10-day-old goslings are fed about 6 times a day and 2 times at night.
③ In the diet, the ratio of rice to compound feed is 20-30%, and the ratio of green feed is 70-80%. At the same time, it is necessary to add 2-3% bone meal, 0.5% shell meal, 0.3% salt and other minerals to the diet to ensure a balanced nutrition.
④ 1 1-20-day-old goslings mainly feed on green, and the ratio of concentrated feed to green feed is 4-8: 1. At the same time, the daily feeding frequency is reduced to 4-5 times during the day and/kloc-0 times at night.
⑤ The digestibility of ⑤2 1-30/-30-day-old goslings was greatly improved. At this time, green feed (concentrate: green feed = 1: 9- 12) was mainly fed, and the daily feeding frequency was reduced to 2-3 times during the day and 1 time at night.
⑥ 1 1-20-day-old goslings can start grazing. 2 1-30-day-old goslings gradually extend grazing time.
(4) Temperature and humidity management
(1) Keep the temperature at 14-2 1 day after hatching. At the age of 1-5 days, the temperature was maintained at about 27-28℃. 6- 10 days old, and the temperature is maintained at about 23-24℃. 1 1- 17 years old, the temperature is maintained at about 19-20℃. At the age of 18-24 days, the temperature was maintained at about 15- 16℃.
② During the brooding period, the doors and windows in the brooding house should not be sealed, and attention should be paid to ventilation to keep the indoor humidity at about 60-65%.
(3) During the brooding period, the drinking water in the sink should not overflow, so as not to cause the ground to be wet.
(5) Feeding density
(1) Put the goslings in a cage, spread grass mats on the ground, and divide the brooding room into several rooms, with 30-50 goslings in each room. The specific density will be adjusted according to the age of the day.
② At the age of1-5 days, 25 goslings were raised per square meter. At the age of 6- 10, 20 goslings are raised per square meter. 1 1- 15 days old, feeding goslings 15 per square meter. 16-20 days old, feed goslings 12 per square meter. 2 1 day, 8- 10 goslings per square meter. When they are over 22 days old, 8 goslings will be raised per square meter.
(6) Other management
(1) Clean the brooding house regularly, and change the bedding in the house in time.
(2) In the brooding room at night, the lights must be turned on, so as to observe the movement of goslings and avoid the threat of rats.
③ In the process of feeding, if goslings are found to be weak, slow-moving, poor appetite and abnormal feces, they should be isolated and treated in time.
④ Gosling plague: Before feeding, each gosling should be injected subcutaneously with 0.5ml of gosling plague serum in time to prevent it (0.8ml for each gosling in case of treatment).
⑤ White dysentery: Take 0.02-0.04% Lite powder for 5-7 days. If it is preventive, add 0.3% oxytetracycline powder to the feed.
2. Feeding techniques of adult geese
(1) Adult geese have a great appetite for food, strong tolerance to roughage and rapid growth and development. Mainly green feed or grazing, supplemented by mixed feed.
(2) Each adult goose needs to eat about 2-5 kilograms of green feed every day, and breeding geese and fattening geese should be supplemented with 300-400 grams of mixed concentrate as appropriate.
(3) geese aged 30-50 days are fed 4-6 times a day. 5 1-80-day-old geese were fed 3-4 times a day.
(4) Divide every 40-60 geese into one group, and drive them to pasture for grazing (no piling, no sun exposure).
(5) If conditions permit, geese need to release water 1-2 times a day, and at the same time strengthen daily exercise to enhance their physique.
(6) Do a good job in cleaning and disinfecting drinking utensils and tableware, and keep the indoor environment dry and hygienic.
Second, to what extent can a lion goose grow?
1. Lion-headed goose is the largest excellent goose breed in rural areas of China, and it is also one of the largest goose breeds in the world.
2.75-90-day-old meat geese weigh about 5-7.5kg, adult male geese weigh about 10- 12kg, and female geese weigh about 9- 10kg.
3. If the feeding method is mainly grazing, the average weight of 70-90-day-old goslings on the market is about 5.84kg (including 6. 18kg for male geese and 5.5 1kg for female geese), and the semi-net slaughter rate is about 82.9% (including 8 1.9% for male geese).
