Lion-headed geese is the largest species of geese in China and one of the largest geese in the world. When the lion head goose matures, it has three developed sarcomas on its forehead and two cheeks. It has a mouth squat and a meat sinker named after the lion's head. Lion-headed geese are large in size, slow to move and have poor feeding capabilities. However, it is resistant to roughage, has a large food intake and grows fast. 70-day-old geese can weigh up to 5 to 7 kilograms. During vigorous growth, they can grow 150 to 200 grams a day. Adult gooses weighing 10 to 12 kilograms, up to 15 kilograms high; goose weight 9 to 10 kilograms, up to 13 kilograms high. The average slaughter rate of adult geese was 72.3%. Female goslings are usually raised from 7 to 8 months of age to produce eggs, 25 to 35 eggs per year, and eggs weighing about 200 grams. Now the lion head goose breeding technology is introduced as follows: First, the breeding gosling management 1. Gosling rearing. After the goslings hatch from 24 to 36 hours, it is better to eat. Within 1 to 3 days, feed 4 to 5 times during the day and feed 2 times at night, feeding 70% to 80% each time. Goats from 5 to 10 days of age have increased digestive capacity and can gradually increase the number of feedings, feeding 6 times during the day and 2 times at night. Diet formula: rice and mixed feed 20% to 30%, green material 70% to 80%. In addition, minerals such as bone meal 2%-3%, shell powder 0.5%, salt 0.3% should be given in the diet. 11 to 20 days old goslings are mainly fed with green materials, and the ratio of fine material to green material is 1:4 to 8. At this time the young goose has been able to grazing, feeding, feeding times can be reduced to 4 to 5 times during the day, 1 at night. 21 to 30 days old goslings, physical enhancement, digestive ability, fine material and green material ratio of 1:9 to 12, feeding 2 to 3 times during the day, fed at night, and can gradually extend the grazing time. 2. Management of goslings. Because the goslings' ability to adapt to the external environment is not strong, in addition to careful feeding, special attention should be paid to the management of heat preservation and moisturizing. The specific requirements are as follows: Insulation: In general, after incubation, heat for 2 to 3 weeks. At present, the method of combining autogenous heating with artificial heating is widely used in rural areas. The temperature required for goslings of different ages varies from 27°C to 28°C at 1 to 5 days of age, 23°C to 24°C at 6 to 10 days of age, and 19°C to 11 to 17 days of age. 20°C; 15 to 16°C at 18 to 24 days of age. Moisture prevention: The window opening of the brooding room should not be closed. Pay attention to ventilation and light transmission. The relative humidity in the room should be maintained at 60% to 65%. It is not advisable to place wet objects in the room. The water in the water tank should not overflow to keep the floor dry. Grouping: Goslings can be reared on the ground with a sub-grass, and the brooding room is divided into several small rooms with 30 to 50 per small room. Cleanliness and rodent control: Clean the ground and replace the bedding regularly. In the brooding room, there are lights at night to observe the movement of goslings and to prevent rat damage. Segregation: In the daily management, if the body is found to be thin, the movement is slow, and the appetite is not enough, the goslings with abnormal excrement should be isolated and treated immediately. Second, feeding and management of adult geese 1. Adult geese breeding. Adult geese can adopt feeding methods that rely on feeding green materials or grazing, supplemented with supplementary materials. Adult geese grow fast and have a strong appetite. They can grazing all day while feeding properly. Each geese eats about 1.5 to 2.5 kg of green material a day and supplements 0.8 to 1 kg of mixed concentrate. Feeding times: 30 to 50 days of age, feeding 5 to 6 times per day and night; 51 to 80 days of age, feeding 3 to 4 times per day and night. In the diet should be given 3% to 4% of bone meal or shell powder and 0.3% of salt. 2. Management of adult geese. 1 When the climate is warm and the weather is fine, full-day grazing can be carried out. Feed at the pasture at noon, grazing early in the morning on hot days, feeding and feeding at 10 o'clock, grazing at 3 o'clock in the afternoon and returning at 6 o'clock in the evening. material. 2 Check counts before and after grazing to check the feeding and health status of the geese. If sick geese are found, they should be treated immediately. 3 When grazing, take 60 to 100 as a group and rush the geese to pasture. You should walk slowly on the way. Do not gather in heaps, and do not expose the geese to sunlight or rain. 4 Before going in, let the geese wash the body's sludge in the water, rest and feed outside the house, and then rush into the house. 5 Do the cleaning and sanitation of the feeders, basins and other utensils normally, and keep them dry.
