How to raise ducks in winter

? Hygiene and disinfection

Sanitary disinfection is an important link in the basic management of raising ducks. In winter, the weather is changeable, the weather is rainy and snowy, and the temperature drops, which reduces the adaptability and body resistance of ducks. Therefore, the sanitary disinfection work must be timely, thorough and effective. Special attention should be paid to the environmental hygiene and disinfection of small and medium-sized duck houses to prevent ducklings from being infected with diseases and poor growth in the early stage. Disinfecting ducklings with ducklings every day is beneficial to purify the floor, bedding grass and air of ducklings, and prevent ducklings from infecting ducklings with infectious serositis through respiratory tract and injured skin.

The living space of ducks in winter is mostly indoors, and the cleanliness of indoor hygiene in duck houses is the key to solve the overall hygiene level of winter breeding. Practice has proved that the drying and hygiene of bedding grass directly affects the weight gain and feed-meat ratio of commercial ducks. Wet mat grass will produce a large amount of ammonia, resulting in air pollution in duck houses, leading to the epidemic of duck diseases and affecting growth and development.

Temperature and ventilation in winter should correctly solve and deal with the problems of temperature and ventilation and the relationship between them, which will directly affect the overall production level. In general breeding farms, the heat preservation is mainly adjusted by simple furnace fire and agricultural film, and the indoor temperature of ducks of different ages should be strictly adjusted in accordance with the requirements of technical standards. The temperature was 34 ℃ ~ 27 ℃ before 7 days old, 26 ℃ ~ 18 ℃ from 8 days old to 21 days old, and 15 ℃ ~ 20 ℃ from 22 days old to listing.

Whether it is ventilated or not should be determined according to the concentration of ammonia and carbon dioxide in the duck house. generally, there is no dazzling and difficulty breathing when entering the duck house, and the temperature is suitable. A small ventilation hole can be opened above the roof of the duck house for small air ventilation. If you feel dazzling and have difficulty breathing when entering the duck house, you should find out the reasons for the high concentration of ammonia and carbon dioxide in the air, such as the dryness of the bedding grass, the sanitary condition of the drinking water feeder, disinfection and so on. Problems should be dealt with in time, at the same time open ceiling ventilation facilities or vents, air flow ventilation, do not carry out vertical and horizontal ventilation, resulting in a sudden drop in indoor temperature, leading to ducks catching cold.

? Drinking water and water temperature control

Water is a necessary substance in the growth process of ducks. it should always provide ducks with easy-to-absorb, clean and hygienic drinking water, and pay attention to the temperature of drinking water, especially during the period of brooding. The ideal drinking water temperature of ducklings is 20 ℃ ~ 25 ℃, and that of middle adult ducks is 10 ℃ or slightly higher. Never let ducks drink ice water in winter. If the amount of water consumed by ducks decreases, the intake of ducks will decrease in 24 to 28 hours, thus affecting the growth rate, and the resistance of ducks to diseases will also be reduced accordingly.
