First, drinking water hygiene. Drinking water should drink tap water or clean well water, try to avoid drinking river water, contaminate it with a waterproof source, and infect the disease. Drinking water systems are cleaned and disinfected on a regular basis because the tanks and pipes are prone to bacterial growth and contain dirt or contaminants. The specific approach is: First, discharge all the drinking water system cleanly, then add chloride-containing water (50 mg/kg), soak the entire system for 30 minutes, and then rinse the entire system for 15 minutes. This can greatly reduce the retention of dirt and impurities and the growth of bacteria. Drinking water should continue to add chloride to improve drinking water hygiene conditions. Open drinking water systems (eg sinks, Paramount drinking fountains) should be filled with enough chloride in the pump or tank to ensure that the furthest water supply system still contains 3 mg/kg of chloride. When using a nipple drinker, there should be 1 mg/kg chloride at the furthest end of the water source. Drinking water should be checked once a month to ensure that there is no E. coli in the water. Second, drinking water and immunity. 48 hours before immunization and 24 hours after immunization, drinking water should be free of any chlorides, drugs or other chemical agents. Before the immunization, the birds should be kept off water for 2 to 4 hours, except during the hot season. Put the correct amount of drinking water into a clean bucket, and mix the skim milk powder in a ratio of 1:400 to make the vaccine suspended in water. 1 to 21-day-old chicks need only 10 to 20 ml of water, and only 40 ml for 21-day-old chicks. Mix the correct amount of vaccine into water. 1. Closed drinking water drinking system immunity. Raise the drinking system so that chickens do not come into contact. Open the end of the drinking system and put all the water in a clean place; pump the vaccine mixture into the system. When the mixture is seen at the end, the end is closed. Ensure that the vaccine reaches any drinking fountain in the system. At this point, the drinking system can be lowered to allow the birds to drink. 2, open drinking water system drinking immunity. Rinse and scrub the water dispenser with clean, sterile water. To provide sufficient drinking space, at least 2/3 of the flock can drink water at the same time. Raise the drinking fountain first, and wait for the fountain to appear when all the fountains are mixed. After the chickens had finished drinking the vaccine mixture, they opened the regular water supply system. Third, the water control program for the first time drinking water: water supply in the morning after feeding 1-2 hours. Specific timing: Shewen temperature above 28°C, no water control; 21°C～28°C, normal drinking water; 18°C～21°C, water supply after finished material 90 minutes; 14°C～17°C, 85 minutes; 10°C～13°C , 80 minutes; 6°C to 9°C, 75 minutes; 2°C to 5°C, 70 minutes; 2°C to 1°C, 65 minutes. The second drinking (at about 11:00): Sherwin 17 °C ~ 28 °C, water for 30 minutes; 8 °C ~ 16 °C, 25 minutes; 2 °C ~ 7 °C, 20 minutes. The third drinking (in the afternoon): Sherwin 17 °C ~ 28 °C, water for 30 minutes; 8 °C ~ 16 °C, 25 minutes; 2 °C ~ 7 °C, 20 minutes. Drinking for the fourth time (starting at half hour before turning off the lights at night): Sherwin 17°C to 28°C, water supply for 30 minutes; 8°C to 16°C, 25 minutes; -2°C to 7°C, 20 minutes; below -2°C, no Water supply. ã€Explanation】 According to the unequal temperature in the house during the control of the water, the water temperature in the shelter is higher, that is, the water level is higher, and the temperature in the greenhouse is lower, that is, the water level is lower; Regularly check and ensure that the drinking water system is working properly to prevent overdose or lack of drinking water due to system damage; constantly check the change of litter in the shed, whether there is moisture in the shed, and identify the cause promptly; after each drinking, especially for the first time drinking water Afterwards, touch the chickens to determine whether the birds are suitable or not.
