The traditional brooding methods of geese mostly use ground level raising. Ground level raising has many disadvantages such as high humidity, poor sanitary conditions, difficulty in controlling the temperature of brooding, and manpower management. The author engaged in breeding geese for many years in the breeding goose farm, and summarized a set of online brooding methods for geese in the work. After years of practice, the online brooding has the advantages of saving labor, low insulation cost, easy management, and high survival rate. It is worth promoting in rural and intensive goose farms. The geese online brooding technology is introduced as follows. Preparation before brooding In order to obtain an ideal brooding effect, all preparations before brooding must be carefully done. 1. Selecting a house and building a net The brooding house should be built in a place where the terrain is dry, quiet, ventilated, warm, and has good lighting conditions. A semi-tilted concrete floor is provided below the net bed to facilitate washing and cleaning of excrement. Each brooding house has an area of ​​about 60m2. It is advisable to raise 500 animals. It should not be too much to facilitate insulation and feeding management. After selecting the brooding house, the brooding net bed can be properly constructed according to the space in the house. The netting grids are preferably welded with angle iron, which is sturdy and durable. The grids are 70 cm high, and the length and width are 5.5 m and 1.5 m, respectively. The net bed is made of iron mesh, and the fence is also made of iron mesh about 45 cm high. Each net bed is further divided into 5-6 grids with iron nets, and 15-20 goslings can be kept in each cell, which should not be too much to prevent the goslings from squeezing each other to death or disability and affecting the brooding rate. 5 brooding net beds can be placed in each brooding house, and a certain channel is left in the middle of the net bed to facilitate the feeding and management of the keeper. 2, the preparation of insulation equipment Insulation is the most critical measure of brooding, insulation effect is directly related to the success or failure of brooding, so we must attach great importance to the preparation of insulation equipment. After years of practice, the author believes that the use of infrared lamp insulation is easy to manage, and the effect is also very good. Three 250-watt infrared lamps are installed on each bed, which is about 60 cm away from the bed. Two long sheets of the bed cover the infrared lamps and the entire mesh bed. The outside of the fence around the bed is also Surrounded with sacks or cloths, used for insulation. On the 1-5th day of the brooding, a layer of sacks was laid on the top of the nets, and goslings were brooded on the sacks. It is important that sacks are changed and cleaned frequently during brooding to keep the sacks dry. 3. Preparation of Feed and Feeding Equipment Materials such as goose materials, vaccines, medicines, feed chutes, drinking fountains, buckets, thermometers, syringes, and lighting facilities should be prepared sufficiently before entering young ones. 4. Disinfection goslings should be cleaned and disinfected for all utensils in the brooding house one week before entering the house. Feeding utensils can be cleaned and disinfected with routinely disinfected drugs such as Poison-killing, Dikang, etc.; brooding houses are fumigated with formalin and potassium permanganate. Formaldehyde is used in 30 ml of formalin per cubic meter of space, and potassium permanganate is used. 15 grams, fumigation 24 hours, open the doors and windows to remove residual gas, ready to enter young. 5. Preheat the infrared light 4-6 hours before the start of the pre-temperature, so that the temperature of the brooding room reaches 28-30 °C. Brooding methods 1. Temperature insulation of geese is a very important task. The temperature of the young chicks should be maintained at 30-32°C during the first week, and then decreased by 2-3°C per week until it falls to 21-23°C. After keeping the temperature until the slaughterhouse is turned into a gosling. The adjustment of the temperature is controlled mainly by increasing or decreasing the number of infrared lamps and controlling the sealing of the insulation cloth cover on the brooding bed, which is very convenient. Generally, each brood bed is insulated with three infrared lamps in the first week, and two infrared lamps are used in the second week. From the second week, when the temperature is high during the day, some or all of the infrared lamps can be turned off or turned off. Cloth cover, adjust brooding temperature. 2. Breeding density: 15-20 broods per square meter net bed, each brooding bed is divided into 5-6 cells, 20 broods per cell in the first week, 15 in the second week, followed by weeks The increase in age gradually reduces the number of broods per cell until the transition. 3, feeding and drinking gosling gossip after the first admission with warm water to adjust drinking water, vitamin B can be added in drinking water and other auxiliary drugs. Feeding is started 2-3 hours later, and chopped green fodder can be used to feed young geese or broken rice. During the brooding period, free drinking water and regular feeding are used throughout the day. During the first 1-2 weeks, 5 meals are regularly fed each day, and thereafter, 4 meals can be changed daily until the transition. 4, ventilation and defecation The first 1-2 weeks to insulation, ventilation can be carried out at noon every day, every 10-30 minutes, gradually increase the ventilation and ventilation time from the third week, gradually reduce the temperature, Promote feather growth to facilitate warming. Gooses are waterfowl and have more water in their excreta and require daily cleaning of the excrement to reduce the humidity and harmful gas concentrations in the brooding room. 5. Epidemic prevention and medications The most common disease of young goslings is gosling plague, in addition to bird flu and duck plague. Therefore, in addition to attention to insulation, the first day of age can be injected subcutaneously anti-goose lice serum, each 0.5 ml; 25-28 days of intramuscular injection of duck plague attenuated vaccine, each about 10-12 feathers. Goslings have strong resistance to disease and do not need to put drugs under normal conditions. However, in the first week of drinking water, norfloxacin and various vitamins can be properly added to enhance physical fitness and increase resistance. 6. Timely transit The age at which goslings are transferred from a brooding house to a gosling depends on the local climatic conditions. Generally, it is carried out at 4-5 weeks of age, and the days of warm weather, sunny weather and windless days are selected to transfer. 3 days before and after the transition, water-soluble vitamins, glucose and other drugs can be added to drinking water to ease the stress caused by the transition. After entering the goslings, special attention should be paid to strengthening the heat preservation and management work to prevent sudden changes in the ambient temperature and cause the goslings to catch cold or squeezing each other to death and disability, affecting the brooding rate. Brooding effect We bred geese every year from 1996 to 2001. We have obtained ideal brooding effects for 6 years. The survival rate of chicks at 28 days stayed at 97.5%-98.8%, and the average weight of goslings at 28 days was 2.17. -2.28 kg, feed ratio 1.68-1.92. Experience Summary 1. Goose is a water bird, with obvious features such as a large amount of drinking water, bathing in water and other characteristics. Online brooding changed the living habits of geese. The entire brooding period did not require a bath. According to many years of feeding observation, the goslings did not show obvious incompatibility. In traditional ground brooding methods, due to the high humidity on the ground, the body of the gosling directly comes into contact with the feces, and the hygienic conditions are poor. After the brooding, the geese must go into the bath, and when the weather is cold, they can easily cause respiratory diseases. 2. On-line brooding, goslings do not come into contact with feces, reduce infectious diseases, thereby reducing the incidence of gosling period and the cost of medication. 3. Elevated online brooding is conducive to the removal of feces. It can effectively reduce the infringement of harmful gases such as carbon dioxide, hydrogen sulfide and ammonia on goslings, effectively increase the survival rate of goslings, and avoid the excessive labor intensity caused by the use of litter. This saves litter costs and labor and improves economic efficiency. 4. The online brooding is not only suitable for the majority of rural households, but also particularly suitable for intensive and modern goose raising, which can greatly increase the labor efficiency and utilization rate of goose houses and is worthy of wide promotion.
