Meat duck simple greenhouse feeding technology

Technical points:

Plastic greenhouse site selection and construction

Large-scale sheds for large-scale ducks should be built in places with sunny leewards, well-drained water, convenient transportation, proximity to water sources, high topography and dryness. Arched sheds: east-west oriented, with a height of 2 meters or more, and a height of 25 centimeters above the outside of the shed, with vents on both sides and the top of the shed to facilitate vertical ventilation in the summer. Materials and construction methods refer to vegetable greenhouses.

Duck scaffolding production and installation

If used on the web, the height of the scaffold is 30 cm to 40 cm, which can be made using ready-made bamboo ribs or made by oneself. Placing plastic mats on the scaffolds increases the flexibility.

Feeding management points

In winter, ducks are raised in large greenhouses. From 9 am to 16 pm on the sunny side, one-third of the grass curtains can be rolled up to receive sunlight, keeping the temperature within the suitable range of 18°C ​​to 20°C. Sooner or later, we will cover the straw curtains. In cloudy snow days, all the greenhouses will be covered with straw curtains. Usually, according to the temperature, humidity and air pollution degree in the shed, the ceiling ventilation and ventilation will be irregular. Due to the laying of scaffolds in the shed, which not only maintains a suitable growth temperature, but also achieves off-site feeding, the incidence of duck populations is significantly reduced. However, it should be noted that the construction of greenhouses must be robust and durable. Breeding should closely observe the temperature and air turbidity, adjust at any time by opening the ceiling, etc., and avoid suffocating meat ducks for a long time.

In the summer when using plastic sheds to raise meat ducks, attention should be paid to adjusting diet formulas. Appropriately reduce the energy level, increase the protein, calcium and phosphorus content accordingly, increase the vitamin content in the diet, especially the content of vitamin C and vitamin E. Change the feeding method. Before 8 o'clock in the morning, the ducks were fed to strengthen the night feeding, and the ducks were given plenty of food to drive them to normal feed intake through proper driving and feeding. Summer cooling. In the hot season, according to the actual production, the temperature in the greenhouse after duckling is usually 7°C~13°C higher than that in the greenhouse. Therefore, it is necessary to do a good job in preventing the heat and cooling: we can adopt measures such as reducing the breeding density, increasing the drinking fountains, strengthening ventilation, direct sunlight, and shading.

Precautions

To avoid artificial stress, we should avoid artificially causing frightened ducks in the greenhouse. The above-mentioned materials, water cut, humidity, or people walking in the ducks will aggravate the heat stress. At the same time, the large sheds should be firmly secured so as not to cause stress in summer gale blows on plastic film or shade nets, and even to take away the greenhouses.

Pay special attention to changes in the weather, especially the temperature changes in the greenhouse when the weather changes, especially thunderstorms, on the one hand to avoid leakage of greenhouses, ducks wet; on the other hand by opening or closing the plastic film at the lee, adjust the temperature inside the greenhouse , so as to avoid excessive temperature difference caused ducks caught cold.

Pay attention to disease prevention on the one hand to strengthen the daily feeding and management and sanitation work to prevent the occurrence of infectious diseases; on the other hand, we should pay attention to the prevention and treatment of common diseases in plastic greenhouse ducks.

Heat Stroke: High summer temperatures, hot weather, poor ventilation in the shed or direct sunlight on the duck body can cause heat stroke. The prevention method is to keep the ventilation in the shed cool and avoid direct sunlight. The greenhouse must have good shading facilities. Ammonia poisoning: The method of prevention is to remove feces at regular intervals. The ground level raising is usually cleared once every 2 to 3 days, and the ventilation and ventilation are strengthened. Especially when the temperature is low, ventilation should be paid attention to while keeping warm. Do a good job of vaccination with duck hepatitis and duck gizzards.

Prevention of epidemic duck disease:

Ducklings

The spring, summer and autumn seasons are frequent with high morbidity and mortality. Prevention: A duck plague vaccine was injected at 10 days to 15 days of age. Treatment: Each 100 ducks with Chuanxiong, Codonopsis each 15 grams, talc, cinnamon, licorice each 20 grams, double flower 10 grams, turmeric 12 grams, 8 grams of pepper, Jianshui juice, add 50 degrees white wine 200 ml and mix thoroughly Beverage for ducks. Can not be self-drinking, each 4 ml to 5 ml, with 2 can be cured.

Duckling Hepatitis

Ducks were susceptible to 1 week to 3 weeks old, with multiple occurrences within 5 weeks of age, with rapid onset and rapid transmission. Prevention: Immunity to the female duck twice a year. Treatment: Each 100 ducks with capillaris 100 grams, camphor, rhubarb, gentian, gardenia, astragalus, cork, Banlangen each 40 grams, Jianshui juice plus 500 grams of sugar, ducks to drink water or spices, daily 1 Agent, once every 3 days. At the same time, 50 grams of multi-dimensional ingredients for poultry and 100 tablets of yeast tablets (mashing) are added for each 50 kg of feed.

Duck contagious serositis

Prevention: Add 2% to 4% sulfamethoxazole in drinking water. Treatment: Use gentamycin 7500 international units per kilogram of duck weight, add drinking water, use it for 2 days to 3 days, and add proper amount of poultry multi-dimensional hormones to the feed to improve efficacy.

Duck pasteurellosis

The most acute type of sick duck is often without any symptoms, suddenly flapping a few wings, fell to death. The acute type disease course lasted from 1 day to 2 days. The temperature of the diseased duck rose to above 43°C, drooping tails, increased drinking water, and nose-like foamy liquid. For duck farms where the disease often occurs, they can be fed with olaquindox for 3 days every 10 days, 25 mg per kilogram of feed, or 2 to 3 days per week with andrographis powder, or oxytetracycline. Feeding at 50 mg per kilogram body weight for 2 days has a better preventive effect. The diseased ducks were injected intramuscularly with cadmium and streptomycin in an amount of 50,000 units per kilogram of body weight. Two times a day for 2 consecutive days, the effect was faster. Sulfa drugs, such as sulfadiazine, sulfamethazine, etc., fed 0.05% to 0.1% of spices, and fed for 3 days to 5 days.

Duck colibacillosis

Diseased ducks have a lack of energy, loss of appetite, increased drinking desire, and severe respiratory difficulties. When the egg-laying female duck suffers from this disease, the feces often contain egg white, coagulation protein, egg yolk, and the penis of the male duck are swollen and partially exposed. The duck houses and utensils are usually sterilized once every two weeks and the disease is found to be disinfected twice a week. Gentamicin is given intramuscularly at a rate of 10,000 units per kilogram of body weight, once a day for 3 days, or 20,000 units per kilogram of body weight in water for 3 days. The norfloxacin premix was administered according to the instructions for use of the drug for 3 days. Chinese medicine Poultry, Compound Andrographis has a good effect on this disease.
