1. Preparation of brooding house. Two weeks before hatching, rinse the brooding room, use 10% fresh lime water to sterilize the floor and walls, wash the appliances with 2% caustic soda, and prepare food waste, drinking water, lighting, insulation, exhaust, etc. .
2, select the goose seedlings. The quality of goslings has a direct impact on the survival rate and growth of goslings. Goose seedlings should be selected from the offspring of goslings injected with a small goose plague vaccine. The method of selecting goslings can be summarized as "seeing two touches". A look is to see the gosling's mental state, fluff color. The second touch is to hold the goose neck and chest with one hand. The other hand touches the back from the back to the tail to check if the abdomen is up and observe the reaction when the touch is touched. When selecting seedlings, the following nesting standards can be used to identify: 1 ​​The body weight meets the requirements of the variety, the group is neat; 2 The navel is covered by the abdominal villi, tight and dry; 3 The abdomen is broad and flat, the egg yolk absorbs well; 4 The feather is clean and shiny; 5 Full of vitality, good spirit, and responsiveness; 6 grip in the hand is flexible, struggling and powerful.
3, transport goslings to prevent the cold wind and hot high temperature. In early spring, due to the cold weather, goslings should be transported with enclosed vehicles. However, goslings should not be overloaded in the hatching box. When the temperature is high, the windows can be opened, but the wind cannot be blown directly to the goslings. It is advisable to use open box cars or transport in the evening during the hot summer season. After long-distance transportation or when there is high temperature and insufficient drinking water, goslings are prone to dehydration. Determine the method of dehydration of the goslings, you can first use a few goslings to do drinking tests, such as drinking water after 10 - 15 minutes, the occurrence of cervical backwards, fell to the back, legs twitching phenomenon, indicating that dehydration. At this time, emergency measures should be taken to raise the room temperature to 30--32°C, using 0.9% salt water to soak the leaves, and transport the dehydrated goslings to the plastic film sprinkled with the leaves. After all the goslings have eaten, feed them with food troughs and eat them before drinking.
4, timely drinking and eating. 24 hours after hatching, when most of the goslings have started to peck or pose, they should supply water and feed them, and then feed them after drinking. Drink 0.02% potassium permanganate solution for the first time, first dip the mouth of the gosling into water, make it drink for 3 to 5 minutes, to meet its needs for water, stimulate appetite, and promote meconium discharge. It is beneficial to the later development of goslings. It is best to supply warm boiled water within a few days. Goslings within 3 days of age should be fed with boiled water or cooked to eight minutes of cooked millet, broken rice, or cornmeal, and add egg yolks to them, plus an egg yolk for every 10 goslings. Feeding requirements are non-sticky and stay loose. Feed 6-8 times daily (twice at night). Gradually transition from feeding cooked food to feeding raw food. Do not change it suddenly. From the 4th day of age, some green feeds can be fed. To prevent goslings from picking green food, they can feed the concentrate and then feed the green material. 11- to 20-day-old goslings are mainly fed with green and blue fodder, and concentrates account for 20-30% of the diet. With the increase of age and body capacity, goslings can be grazing. When feeding in large groups, individuals with weak constitutions and slow development should be fed in groups in a timely manner, give some fine material, good materials, and carefully nurse them. After the growth has been caught, they can be fed in groups.
5, pay attention to reasonable feeding. Goslings have small digestive tract volumes, poor digestion, and require fresh feed and easy digestion. If there is no full-priced feed, the concentrate can be replaced with rice, broken rice or cornmeal, and the green feed can be fed with lettuce leaves, cabbage leaves, ryegrass, and the like. Before the broken rice is fed, soak it in water for 2 - 3 hours, drain it and feed it. Before feeding green feed, leaves and rotten leaves should be removed, washed and cut into filaments. When feeding, pay attention to the amount of feeding. Generally, the daily feeding amount per 100 goslings is: 1 to 2 days of age to feed 0.7 kg of green feed and 0.4 kg of concentrate; 3 to 6 days of age to feed green feed 2 Kg, fine material 0.7 kg; 7--9 days feed 35 kg of green feed, fine feed 2 kg; 10-15 days feed green feed 70 kg, 3.5 kg fine material. Gradually increased later. Do not feed dry material to prevent the geese from bloating after drinking enough water because of thirst.
6, pay attention to heat and moisture. Goslings have a weak ability to regulate body temperature, and they should strictly control the temperature and humidity during feeding. The duration of the incubation period varies depending on the species, temperature, age, and the goslings' strength. Generally, it takes two to three weeks for incubation. Suitable brooding temperatures range from 28 to 27°C at 1 to 5 days, 26 to 25°C at 6 to 10 days, and 24 to 22°C and 16 to 20 days at 11 to 15 days. It is 22--20°C and it is 18°C ​​after 20 days of age. Whether the temperature is appropriate or not can be observed by observing the performance of goslings. When the goslings crowd into piles and do not eat, it means that they are cold and the temperature is low. At this time, in addition to warming, they also use hands to disperse the goslings and make them active. To prevent crushed to death. Such as young goose mouth breathing, cry loud and short, increase the amount of drinking water, indicating that the heat, the temperature is high, should increase drinking water, timely and appropriate cooling. When the goslings stretch their legs, three or five groups, lying quietly or regularly eating water, excretion of feces, interval 10-15 minutes exercise once, is a specific manifestation of appropriate temperature. The humidity of the goose house is also very important for the health and growth of the goslings and generally requires a relative humidity of 60% to 65%. Humidity is too high, temperature is low, goslings are susceptible to respiratory diseases and diarrhea; humidity is too high, temperature is too high, goslings are susceptible to “sweatâ€, appetite is reduced, and disease resistance is reduced. Therefore, when the goslings drink water (because the goose is a waterfowl, there are playing habits), so that the goslings do not enter the sink, the water does not change body, do not sprinkle water on the ground, keep the goose house dry. The mat grass or sawdust in the goslings should be changed once every two to three days.
7, the food tank specifications and feeding density should be appropriate. The troughs of different ages are different in the trough. The length and width of the goose and trough are generally 90, 7, and 5 cm. The length and breadth of the troughs of the 7- to 30-day-old goose are 90 and 10 respectively. , 7 cm. The stocking density should be determined according to the feeding conditions and methods. Generally, the number of goslings per square metre for breeding goslings is: 1-2-3 weeks old, 20--35, 3 weeks old, 15 or so, 4 weeks old 10-- Twelve of them were later reduced as the age increased, with 100 in each group.
8. Grazing and launching water in a timely manner. Grazing can increase the ability of goslings to adapt to the external environment, promote digestion and metabolism, facilitate physical exercise, increase health, reduce disease, increase survival rate, and at the same time save a lot of feed. Grazing should be based on the weather, the heat and the age of the goose. When the weather is warm, it can be grazing from 5 to 6 days old, and it can be started after 15 to 20 days when the weather is cold. It can be returned to the brooding room 20 to 30 minutes after the first grazing, twice a day. When grazing should pay attention to the time from short to long, the distance from near to far, slowly drive away; feed before grazing from feeding to feed, so that they are accustomed to eating grass; late release early in the day when cool; goslings chest and abdomen When moulting, grazing should be done after the dew has dried to prevent diarrhea. The goslings are reared until the 4-week-old feathers grow. They should be allowed to swim in the water on sunny days, and gradually adapt to the water.
9, strengthen management, pay attention to disease prevention. Always keep the gossip clean and hygienic. Clean the field and replace the bedding. Feed the bowl and the drinking fountains every day. Always disinfect the utensils and geese regularly. Have a guard at night, pay attention to whether the temperature is appropriate and prevent rat damage. For goslings that have not been injected with gosling ticks, 0.3--0.5 ml serum of anti-goose goose is injected subcutaneously at the age of 1- to 3-days. At the age of 2 days, drugs such as sulphonamides or furans or oxytetracycline should be administered through drinking water and mixed materials. According to the instructions for use, the drug should be used for 3 days, twice daily, 10 days after discontinuation of treatment, and then for 3 days in order to prevent salmonella in goslings. Colibacillosis and fowl cholera.
The gosling brooding technical points
In geese production, brooding technology is the key to raising geese. It directly affects the economic benefits of geese. According to goslings (from the time of shelling to 20 days old), the villus is thin, the body temperature regulation ability is poor, and the digestive ability is weak. It is afraid of cold, heat, and wetness. Now the technical points of the geese brooding are introduced as follows:
