Prepare before brooding. Two and a half months before feeding goslings, the brooding room should be thoroughly cleaned. Formalin solution and potassium permanganate fumigation, close the doors and windows disinfection for 20 minutes to 30 minutes, and then open the ventilation. The brooding utensils can be washed and sterilized with 0.2% potassium permanganate, then washed once with tap water, and then the young gooses are connected to the brooding room. Gosling stocking sites are sprayed with 20% lime milk or 3% caustic soda and disinfected once every half month. Feeding equipment (feed troughs, drinking water appliances, etc.) is immersed in the proportion specified by the disinfectant and then rinsed with fresh water. Put grass, cotton, etc. in the sun for 1 hour to 2 hours before use. Miao geese should be warmed up before entering the brooding room, and the room temperature should be kept at about 30°C.
Temperature and humidity control. Large groups of brooders should be brooded in a brooding house and brooded to lay a litter. Do not let goslings directly touch the ground. Appropriate temperature: 28°C~30°C in the first week, 26°C~28°C in the second week, 24°C~26°C in the third week. The temperature is suitable. The goslings are evenly distributed, quiet and quiet, the feathers are smooth, and the appetite is strong; the temperature is too high. Low, young goslings are close to heat sources, crowded and staring. Their bodies shiver and shrunk. When the temperature is too high, young goslings are kept away from heat, their mouth is puffed, their movement is inconvenient, their drinking water is frequent, and their feed intake is reduced.
The appropriate humidity for the barnhouse is 60%~70%. The wet bar is easy to make the goose suffer from colds, diarrhea and other diseases. An effective way to adjust the humidity is to diligently change the litter, often cleaning the excrement, and keep the floor and the barracks dry. The geese should be kept clean and dry, air circulated, and indoor light should be available. The geese should be allowed to release outdoor activities 2 or 3 times on sunny days. Open the goosehouse doors and windows to remove ammonia, so that the indoor air is fresh, which will help promote the healthy growth of geese. The walls of the goose house are closed on all four sides and the holes are to be plugged. The rear window is closed with a plastic film. Hang curtains at the entrance, dim the light and keep the environment quiet.
Goslings drink and eat. The first drinking of goslings after hatching is called “tidal mouthâ€, and the time of tide should be within 24 hours after the goslings are hatched. Cold weather in autumn and winter. Drink warm water at about 30°C. Add 0.05% potassium permanganate to prevent digestive diseases. After long-distance transportation, feed 5% to 10% glucose water to help yolk absorption and promote fetal growth. Excrement discharge will help improve the survival rate. The first feeding is called eating, which should generally be done 36 hours after the shell is hatched. Eating too early can cause indigestion. The timely start of eating is conducive to the promotion of meconium discharge, stimulate appetite, and contribute to the gradual improvement of digestive function. Opened feed should be selected clean fresh rice, broken rice, vegetables, etc., millet and broken rice to go through 1 hour to 2 hours soak cooking, vegetables, young grass should be chopped and chopped, should not eat when feeding too full.
