4. General Management 1 Ventilation Currently, most open duck houses are ventilated with the adjustment of the temperature and humidity in the house as the main criteria. The ventilation is controlled by the number of open doors and windows and the length of opening and closing time. The windows should be set high, so that even if the wind does not reach the duck body, it will help eliminate the hotter and lighter exhaust gases. At the same time, to prevent the thief wind and temperature fluctuations caused ducklings cold and poor growth.
2 Density Usually, 400-1000 ducks are appropriate for the ducklings. When the ground is raised, about 20 per square meter at the first week of age, about 14 at the second week of age, and no more than 10 after the third week of age; The density of the net surface raising and the ground net combined can be larger, and can be up to 1/3 more.
3 temperature ducklings must be grown to a suitable temperature, to avoid significant indoor temperature rise and fall. At the age of 1-3 days, the temperature was 28-30 Co; 4-6 days old, the temperature was 24-26 Co; 7-10 days old, the temperature was 20-23 Co; after 11 days, it was analogized. When the indoor temperature is lower than 20Co in the early stage, infrared lamp or electric heating plate can be used for heating. Pay attention to prevent ducks? A href=http://>Duck??12.
4 Humidity The appropriate relative humidity during brooding is 56-70%, which is close to the humidity of the ducklings when they are hatched. This can prevent the ducklings from emitting a large amount of water due to the dry air, affecting the normal function of the body.
5 Light The young ducks have low feed intake and low feed intake after they start eating. To ensure that the ducklings have enough time to eat and drink, they usually use 24 hours of light throughout the first 3 days, ie artificial light is added at night. It is better to use ducklings to see feed and drinking water.
6 The procedures and types of vaccination immunization vary from region to region, depending on the condition of the local infectious disease. It is best to conduct investigations by poultry disease experts, develop a good immunization plan and implement it strictly.
7 Timely elimination As the ducklings in paddy fields are mainly carried out under natural conditions, ducks must be healthy. Poorly developed and poorly growing ducks should be eliminated in due course.
(III) Management of Ducks in Rice Fields
1. Time for entering the paddy field Ducks need to pay attention to the time of fielding. The ducklings are hatched for 20 days. The weight is about 100 grams or more. The rice is thrown for 15 days and transplanted for more than 12 days. It can be put into the field. Adult ducks should be properly postponed for 2-3 days.
2. Field Feeding Facility Preparation 1 Prepare 2.5 kg of high-quality nylon net per rice paddy field. Irregular rice fields and narrow rice fields should be prepared for more. Around the field, a three-finger nylon net is used to enclose an escape-proof ring. The fence is 60 cm high and every 1.5-2 meters of trees is a support rod.
2 In the corner of the field, a duck house should be built for a size of 10 square meters per 10 ducks. The house should be covered so as to avoid the sun and the rain. It must be aired on three sides, but it must be ventilated and ventilated. Spread out and dig a water letter that is 2 times the size of the duck house, 50-60cm deep.
3 In the paddy field, a number of high-yielding ditches with a width of 35 cm and a depth of 30 cm were excavated.
3, stocking density of ducks is about 15 feathers per acre, young ducks can be appropriately increased according to the situation.
4. The duck does not have the habit of grazing during the brooding period. Before going down in the field, it is necessary to conduct feeding training. Ducks in paddy fields mainly eat foods such as weeds, insects and aquatic animals in rice fields. After adjusting the ground-feeding millet, the millet is sprinkled into shallow water to allow the duck to feed. After many times, the conditioned reflex is formed. After that, the rice field will actively seek food.
5, each duck with 50-100 grams of rice each day, corn, forage and other feed supplements, pay attention to time, fixed-point feeding, pay attention to increase or decrease the amount of feeding, not too much or too little. Prevent the use of moldy, stinky feeds, and stinking, raw animal feed.
6, a reasonable arrangement of grazing time.
1 Determine grazing time based on temperature and water temperature. Paddy field grazing, ventilation is not as good as rivers and ponds, due to shallow water, easy to be hot, when the temperature exceeds 30Co, should not be put down to the field duck. Especially during the hot summer months, it should be done before 9 o'clock in the morning and cool in the afternoon.
2 Turn grazing properly. It is not advisable to repeat grazing on the same paddy field for a few days. Paddy fields have different growth periods and harvesting periods and it is best to match them.
3 After the rice is harvested, there are a large number of remnants in the field. At this time, grazing can be concentrated.
7. Rice and duck are coexisting, and ducks have been in the hot summer for a long time. Therefore, duck shelters are kept on the basis of the prevention of rat damage, and a shady branch or small pergola is set. The high-yield ditch should be filled with water to allow the ducks to splash more and play the role of cooling off the sun.
8, combined with pest control ducks. Firstly find out the pest situation, such as when the pest is heavy, reduce the feed, so that the duck in a state of starvation, a large number of pests, give full play to the purpose of pest control.
9. Before rice sprays, ducks are baited in the duck house.
10. Late management.
1 The rice is harvested during the milky period to prevent the duck from eating rice. To facilitate the collection of ducks, ducks are usually fed with the habit of hearing some kind of sound gathering.
2 The recovered duck can be taken back home or in a field house.
Third, the prevalence of common duck disease In the open-ended breeding of ducks in paddy fields, it is easy to infect the disease and spread the disease, and it should pay great attention to the prevention work of ducks.
1. Ducks, ducks, ducks, 7-day-old, chicken embryo billion weak seedlings, 0.2-0.5ml / feather meat injection. After 7 days, antibodies can be produced and meat ducks can be protected on the market.
2. Duck viral hepatitis immunization Ducklings: 1-3 days old, embryonized chicken attenuated vaccine, 0.5 ml/head, subcutaneous injection, antibody production 2 days later, reached high levels in 5 days.
3, duck cholera immunization program:
Cholera vaccine for ducks I am a vaccine for poultry Pasteurella multocida, such as 731 attenuated bacterins, inoculated ducks over 2 days of age, immunization period of up to three and a half months. Avian cholesteric aluminum hydroxide latex seedlings are used for ducks aged over 2 months. Each duck was intramuscularly injected with 2 ml, followed by a 10-day interval injection, an immunization period of 3 months, and an inactivated vaccine for the poultry cholera oil emulsion. The duck was used for more than 2 months. Each duck was subcutaneously injected with 1 ml. The immunization period is 6 months. It has also been reported that a vaccine made of Pasteurella agarensis, each duck 2 ml intramuscular injection, can produce 4-5 months of immunity.
Fourth, pay attention to matters
1. It is recommended to use low-toxicity, high-efficiency and low-residue pesticides to prevent and control rice diseases and insect pests, and not to use pesticides as much as possible.
2. When building a duck house in the field, consideration should be given to preventing rodent infestation.
3, during the application of rice fields, ducks should be collected from the field in time, after the safety interval, and then down to the field duck. During the safety interval of rice field application, duck drinking water and paddy field water should be separated to prevent duck poisoning and duck product contamination.
4. Places where ducks have passed or ducks have been infected with contagious diseases, as well as water and rice fields contaminated with mineral oil, ducks cannot be kept.
2 Density Usually, 400-1000 ducks are appropriate for the ducklings. When the ground is raised, about 20 per square meter at the first week of age, about 14 at the second week of age, and no more than 10 after the third week of age; The density of the net surface raising and the ground net combined can be larger, and can be up to 1/3 more.
