The experience of raising meat ducks in winter

The main results are as follows: 1. The breeding period is long. The room temperature should be kept at 32 ℃, and the temperature should be reduced by 0.5-1 ℃ per day until the temperature is removed for a long time.

2. It is difficult to prevent dampness. Ducklings drink a lot of water, feces are sparse, coupled with poor ventilation, it is easy to make the duck house wet, the wet environment makes ducklings consume more heat energy, and the survival time of pathogens in the environment is longer, which increases the chance of infection and disease of ducklings, which is not conducive to the growth of ducklings. Therefore, the management should pay special attention to keeping the brooding environment dry.

3. It is difficult to keep warm in brooding. It is cold in winter and spring, so it is difficult to keep 32 ℃ in the rearing room within 1-2 days after entering the chick, and 18-25 ℃ in the middle chick. If the temperature is not enough or there is a thief wind, ducklings are prone to colds. It is necessary to wait for the ducklings to grow into full-fledged ducklings before they have better cold tolerance.

4. There is a lot of dung on the sports ground. In winter, ducks often rest on the playground. Therefore, there are relatively many feces on the site, coupled with the low temperature, the long survival time of pathogens, and the concentration of ammonia volatilized from feces, which is easy to affect the growth and health of ducks. Therefore, it is necessary to clean and disinfect frequently in winter and spring.

Main points of feeding

1. Select the young seedlings. Choose to come out of the shell at the same time, with bright eyes, strong posture, flexible movement, shiny feathers, soft abdomen, good absorption of yolk, good navel healing, fat flippers, strong hands struggling, warm feet, loud calls, strong contraction of the cloaca and moist clean ducklings. Weak chicks are often crushed to death because of stacking each other when raising chicks.

2. Get through the hurdle of raising chicks well. The rearing period is long in winter, especially the management of 1-7-day-old chicks. To have more affluent brooding houses, thickened bedding grass, about 20 per square meter, so that ducklings have a larger activity space. To do a good job of heating ahead of time, keep 32 ℃ when entering the chick, and then reduce it by about 1 ℃ every 2 days until it is deheated. The control of temperature is based on the principle that ducklings do not gather together. The utility model has the advantages of suitable temperature, strong feeding power, uniform individual and fast weight gain. Duck breeders should often observe the situation of the ducklings and disperse the ducklings in the pile every 20-30 minutes. Should pay attention to ventilation, indoor should be no irritating odor, prevent gas poisoning, ammonia poisoning. In sunny weather, drive the chicks to shelter from the wind to graze or bask in the sun. The ducks with smaller and weaker individuals should be picked out and reared in time in order to improve the survival rate and the evenness of the population.

3. Online brooding is adopted. Due to online brooding, easy to clean, sanitary feed and water, ducks have less contact with feces. Therefore, ducks are not easy to get sick. After the ducklings are raised online for 5-7 days, when they are strong, they can be put on the ground for further breeding.

4. Provide clean drinking water. Ducklings 24-26 hours out of the shell to drink water, it is best to use deep well water or warmer tap water, can be injected in the water to prevent disease. When raising flat on the ground, it is best to use flowing water to raise chicks.

5. Pay attention to feeding hygiene. One hour after drinking water, you can start eating, and you can eat freely after eating. Don't suddenly change the feed. Feed regularly, do not feed mildew, control free feed intake, and often remove mildew from the edges and bottom of the trough (especially when it is overcast and rainy for a long time).

6. Strengthen management and prevent stress. Always remember to create an environment for a smooth transition for ducks. Give dim light at night, can eat and prevent rats, it is best to be cared for. Duck farmers should often contact the ducks, call the ducks, and train the ducks. Water release gradually adapted, the first water release for 10-20 minutes each time, and then gradually extended. Graze and release water during the day, drive the chicks indoors or keep warm in small groups on the playground at night. In case the ducklings are piled up for a long time and die when it is cold at night. Playing music to ducklings can induce grazing or return to the fence, and can also reduce stress caused by sound. In addition, attention should be paid to rodent control and animal prevention. Rats, dogs, weasels and eagles will prey on ducklings, causing flocks of ducks and spreading epidemic diseases. Field crops have been harvested in winter, rats will migrate without food, and a large number of rats in the field will gather in the pasture and should be caught or poisoned.

7. Make full use of sunlight. Make full use of sunlight in winter. Winter sunshine can increase body temperature, save energy, increase appetite, kill pathogens, and improve disease resistance. It is best to use shelter to graze or bask in the sun, which can reduce the blood stasis in the ducklings' legs, which is beneficial to the health of ducklings and weight gain.

8. Create a good environment for activities. Create a good environment for ducks to sleep and rest when they are full.

① removes sundries from the duck playground and fully exposes the playground to achieve the purpose of disinfection and cleaning through sunlight exposure.

② reorganizes the playground, including filling up depressions, removing stagnant water and repairing sewer slopes. Due to water waves and activities such as ducks and fish, the soil slopes are gradually scoured or collapsed, which makes it inconvenient for ducklings to come ashore to feed. Therefore, the launching slope needs to be repaired frequently. Some people are paved with red brick and the effect is good (especially on slopes with large slopes).

③ cleans feces frequently. The accumulation of feces is easy to cause pollution in the sports ground and affect the health of ducks. Clean the dung frequently, clean it before it rains, rinse after it rains, and keep the duck's activity area clean. It is best to choose or build a 5-35 degree slope, which does not accumulate water in rainy days and is easy to clean.

④ decreased the stocking density. There are two ways to reduce stocking density. One is to raise less per unit area, and the other is to increase the number of sports venues, which naturally reduces the number per unit area.

⑤ collects animal carcasses in time and puts dead rats, dead fish, dead ducks and other animal carcasses in the field into corpse wells or deep burial.

9. Get back to the lost ducks in time, so that each duck can get the feed in time.

10. worthless diseases, weak and disabled individuals should be eliminated in time, and harmless treatment should be carried out during elimination.

11. Pay attention to epidemic prevention. In particular, it is necessary to do a good job in prevention and immunization of duck hepatitis, serositis, influenza and aspergillosis. Do not purchase poultry and its products from outside. Strengthen the disinfection of vehicles and personnel, especially the disinfection of ducks and cages, and thoroughly disinfect the site immediately after the completion of the work.

12. Be on the market in time. The feeding period of meat duck in winter is 43-47 days, and the body weight can reach 3.1-3.4 kg. At this time, the growth performance of meat duck is the best and the feed cost is the lowest. It's best to go in and out when you go public. After stress, ducks will reduce feed intake, or even refuse to feed, seriously affecting the weight gain and economic benefits of meat ducks. Therefore, it should not be frightened in the process of feeding, and it should be sold out at one time.
