Improving the survival rate of goslings

Prophylactic administration is generally carried out after the hatched feathers are transported to the brooding room. After a rest, they can drink water. Drink 5% multi-dimensional glucose water or 5% to 8% sucrose water for 1 day to increase the energy of the goslings and promote meconium elimination. 2 days old drink 0.02% potassium permanganate water, to clean and disinfect the gastrointestinal tract, and add manganese; 3 days old drink 0.1% Andrographis and Radix (Daiqingye) water, to clear the stomach detoxification, stomach sterilization; 4 to 7 days of age were fed with 0.02% oxytetracycline and doxycycline (10-20 mg), as well as sand and other drugs to prevent the gastrointestinal diseases of goslings. Once the goslings are found to have anorexia, snoring, and fecal abnormalities, they should be immediately given 0.03% oxytetracycline or kanamycin, mixed with water and taken orally, 30 to 120 mg per liter of water, 2 times a day for 2 to 3 days.
Drinking water and eating the first 3 days of the best drinking warm water, drinking water every day and night not less than 6 to 8 times. After long-distance transport or lack of drinking water, dehydration is prone to occur, manifested as dry mucous membranes, sunken eyes, dry skin on the ankles, shrinkage, inverse feathers, and weight loss. Immediate measures should be taken to improve the room temperature for brooding to 30 °C to 32 °C. 0.9% salt water soaked fine leaves, so that they fully feed, then feed the fine material, and finally drinking water, found that when the gosling dehydration or extreme thirst, the first drinking water must limit the amount of drinking water, gradually increase the amount of drinking water, avoid Binge drinking to prevent water poisoning. One hour after drinking, you can start eating, and start to use small grain feeds like millet, broken rice, etc., soaked in water for about 2 hours, drained before feeding, or fed half-baked rice, not sticky or rotten. , Or steamed sixty-seven cooked cornmeal noodles, using bran or cornmeal to feed the head into small particles. When you eat, you can sprinkle the concentrate on a mat or a dark plastic sheet and allow it to be eaten. Then feed green feed. Every day and night feeding 6 to 8 times, including 2 or 3 times at night. The number of feedings per day should not be less, and the amount of each feeding should not be less. The method of feeding is to "feed first, then feed regularly, quantitatively, and less frequently to prevent overeating." After 2 to 3 days, regular, quantitative, and qualitative feedings were performed. At the age of 4 days, insoluble river sand was fed to help digestion. The feed amount was 1% of the concentrate, and the size was 1 to 1.5 mm. The gravel was rinsed with clean water or the casserole was sterilized before feeding. The fed amount was fed once a week. Feeding and opening feeds every day, otherwise it will lead to “garbage licking”, affecting the feed intake of other feeds.
The "third degree" control "third degree" refers to temperature, humidity, and density. The incubation period of a typical gosling is 3 to 4 weeks. The temperature in the house should be stable. Stand down steadily, do not flicker, and become hot and cold, otherwise it will affect the health and uniformity of the goslings. The thermometer should be hung in the middle of the geese. The height should be about 8 cm from the bedding. Keep the young house dry as much as possible, which will help reduce the occurrence of gastrointestinal diseases and coccidiosis. 1 to 5 days old: Temperature 27°C to 28°C, relative humidity 65% ​​to 75%, stocking density: 15 to 20 per square meter for medium and small geese species, 12 to 15 large geese species, 6 to 10 days old : Temperature 25°C~26°C, relative humidity 60%~65%, stocking density: 10~15 medium and small goose species, 8~10 large-scale goose species, 11~15 days old: temperature 22°C~24°C, Relative humidity 60% to 65%, stocking density: 6 to 10 medium and small goose species, 5-8 large-scale goose species; 16 to 20 days old: temperature 20°C to 22°C, relative humidity 65% ​​to 70%, Breeding density: 5 to 6 medium and small geese and 4 to 5 large geese.
Ventilation and light The fresher the air in the brood chamber, the faster the gosling grows, the higher the survival rate. If you find brood chamber carbon dioxide, ammonia, hydrogen sulfide and other harmful gases, there are pungent, eye feeling, you should first catch up goslings activities for a while, and then gradually open the doors and windows ventilation, do not have to go to the body of the goose wind . Generally, people do not feel sulking when entering a goose house, and there is no pungent smell.
During the brooding period, it is generally necessary to maintain a longer period of light, which is conducive to familiarizing the goslings with the environment, increasing the exercise, and facilitating the intake of food and drinking water. 1 to 3 days of age 24 to 23 hours of light, 4 to 15 days of 18 hours of light, 16 days of age gradually reduced to natural light, need to feed lights at night. The light intensity of 0 to 7 days of age uses a 40 watt bulb for every 15 square meters, and after 8 days of age, it uses a 25 watt bulb, which is about 2 meters away from the back of the goose.
Grazing and watering Gosling grazing sites should be "close, flat, grass tender, clean, secluded." The size of the geese is 300 to 500. It is advisable to form a group of ages, sizes, strengths and weaknesses, and it is best to adopt the management method of all-in and all-out systems.
The initial grazing and watering time of goslings depends on the outside temperature. Warm weather begins to grazing on 7-11 days, and on cold days 15-20 days. Must choose wind and warm weather. After the feeding, they are rushed to the nearby flat grassland for grazing, allowing them to freely eat grass, grazing for about 0.5 to 1 hour, rushing to the clean shallow pond for leisure for a few minutes, and then rush to the shore to comb their fluff. . Avoid grazing at noon during sun exposure, and when the storm comes, immediately return the goslings to their homes or places sheltered from wind and rain. After the initial grazing, as long as the weather is good, we must adhere to every day, gradually increase the grazing time with the increase of the young age of the goose, increase the distance of grazing, and accordingly reduce the number of feeds, do not feed during the day, just night feeding. Every day strive to put 5 to 6 full, the so-called full, that is, the goose's sac hair drum swollen to the throat below, that is, a full sign, count the number of harvest, dry hair and then back to the brooding room.
The epidemic prevention disease is injected at 1 to 2 days of injection of 0.5 to 1 ml of gosling plague antiserum or 1 ml of goat geese anti-immune yolk antibody. The goose can also be injected subcutaneously with a 10-fold dilution of goslings at 3 days of age.瘟 vaccine 0.2 ml/body; 5 to 7 days old goose paramyxovirus oil emulsion inactivated vaccine muscle or subcutaneous injection of 0.3 ml / only; goslings often occur in the area goslings in 5 to 10 days to take duck attenuated vaccine Two to three servings were intramuscularly diluted with 0.5 ml normal saline; about 30 days of age, 0.1% of the enemy was killed and sprayed on the goose to kill ectoparasites.
