The breeding of commercial geese needs to go through three stages: the brooding period, the shelf period and the fattening period. The technologies and methods required at each stage will be different.
1. Technology and methods of the brooding period
The brooding period refers to the period from 1 to 28 days old of the gosling, that is, the first 4 weeks. The temperature of the gosling is mainly controlled. , humidity, ventilation and ventilation of the brooding house, breeding density, feeding and drinking water, and epidemic prevention.
Temperature control: The temperature should be controlled at 35-33 degrees for 1 to 3 days, because at this time, the goose egg yolk has not been completely absorbed, and the physiological functions have not yet fully matured, so external heating is needed. Increase the speed of egg yolk absorption, so these 3 days can also be called the continuation of incubation. From 4 to 7 days, control it at 32 to 29 degrees; from 8 to 14 days, control it at 28 to 22 degrees; from 15 to 21 days, control it above 18 degrees; from 22 to 28 days, control the night temperature above 15 degrees, and you can take it off during the day. temperature.
Control humidity: Humidity is generally controlled at around 65. The main concern is to prevent the humidity in the brooding house from being too high. Once the humidity is too high, it is easy for goslings to peck their feathers. During the brooding period, do not sprinkle water in the brooding room, and do not clean kettles and feed boxes in the brooding room to prevent the humidity indicator from exceeding.
Keep abreast of the breeding density: 20~25 birds/square meter in the first week, 15~20 birds/square meter in the second week, 10~15 birds/square meter in the third week, 5~5 birds/square meter in the fourth week 10 birds/square meter, control the density reasonably to prevent goslings from pecking their feathers.
Ventilation and ventilation management: Ventilation and ventilation should be carried out after the third day of the gosling period to prevent the excessive ammonia smell in the brooding room from inducing gout, serositis and other diseases in the goslings. . When ventilating, be careful not to open the vents too large, try to avoid opening them in half, and adhere to the principle of "opening the vents between 12 and 14 o'clock on cold days, and between 10 and 16 o'clock on hot days." When the goslings are young, it is best to open the vents in conjunction with heating to prevent the temperature in the brooding room from dropping too quickly, causing the goslings to catch a cold.
Boiling water and food: The so-called boiling water and food is the first time the brooding goslings drink water and eat food. When boiling water, you must pay attention to the fact that the water temperature is consistent with the temperature of the brooding room, and put in drugs to prevent goslings from diarrhea, such as gentamicin, kanamycin, ciprofloxacin, etc. In addition, you also need to put in some drugs to increase the resistance of goslings. Multidimensional anti-stress, etc. When giving water to the goslings for the first time, it is best to train them one by one, that is, hold the goslings with your hands, immerse the goose beaks in the water, and teach the goslings to drink water. This can effectively prevent the goslings from becoming dehydrated. occur.
After the goslings are boiled, they can be cooked. You can choose high-quality pastures, such as ryegrass, chicory, etc., or choose broiler goose feed or broiler feed.
Epidemic prevention: Epidemic prevention is also a key task at this stage. Enhanced epidemic prevention against gosling plague should be carried out between the 5th and 7th days, and gosling plague vaccine should be injected. The dosage should be determined according to the size of the goose. On the 12th~ Paramyxovirus prevention is carried out on the 14th day, and bird flu prevention is carried out on the 21st day. The vaccine prevention work is done only three times, mainly to prevent the occurrence of viral diseases. As for other metabolic diseases and bacterial diseases,
