Pathogenic factors, such as germs and viruses, will remain in the empty henhouse. If the chickens are not disinfected, they are easy to be infected with pathogens and get sick. A week before the chickens enter, the henhouse should be cleaned and disinfected strictly and thoroughly. The mixed solution of formalin and potassium permanganate can be used for fumigation. During the fumigation, the doors and windows of the henhouse should be closed, and the windows should be opened for ventilation after disinfection for 24 hours.

Second, the selection of chicks

When selecting chickens, we must choose hatcheries with big manufacturers, good reputation and after-sales service to enter the seedlings. Randomly grab a few chickens from the chickens to be purchased and dissect them to see if there are lesions in the liver, kidneys, gallbladder, lungs, intestines, etc., so as to ensure the health of the purchased chickens.

Third, the chicken coop temperature control

Chickens are very demanding on temperature, especially those that have just hatched, but they can't copy the textbooks. When they are just put into the henhouse, the temperature rises to 34/35 degrees. Because the temperature of the chicks in the transport car is definitely not so high, they suddenly enter the high temperature environment, and such a temperature difference is stressful and harmful to the chicks.

The correct way is that when the chicks are just put into the henhouse, the temperature of the henhouse can reach about 30 degrees, and the temperature can be gradually raised to 35 degrees after 3-4 hours.

Fourth, the humidity control of chicken coops

Few systems of chicks have been developed perfectly, especially the respiratory system of chicks. If the humidity in the henhouse is too low, in the high temperature environment, the respiratory mucosa of chickens is easily damaged and respiratory diseases are induced; Of course, if the humidity of the henhouse is too high, it will also cause the disease of chickens.

Under normal circumstances, the humidity of chickens within 7 days of age should be controlled at 60% ~ 65%; After 7 days old, the humidity of chicken house should be controlled at 50% ~ 60%.

V. Feeding of chicks

1, drink water in time

After the chicks are pulled back, they should be given water in time. It is very important to drink it for the first time. Drinking water in time (try to drink water within 36 hours after hatching, preferably within 3 hours after hatching) can promote the absorption of yolk in the body, and help the chicks to eliminate meconium in time to stimulate their desire to eat.

The drinking water provided to the chicks must be clean (warm boiled water) and ensure that the chicks can find water within half a meter. The temperature of drinking water should not be too low or too high. If it is too low, the chicks will take a bath and catch a cold. If it is too high, the amount of drinking water will be insufficient, and if it is too high, the intestines of the chicks will be lost. The most suitable water temperature is between 18-24 degrees.

Adding glucose and vitamin C to the drinking water of chickens can provide certain nutrition for chickens and alleviate the stress reaction of chickens during transportation.

Step 2: Feed

After the chicks are first drunk, they will eat opening material. Don't control the feed when you first start feeding the chicks. Don't control the feed, and don't add a lot of feed in the trough, so that the chickens will be wasted if they can't finish eating, and the feed is prone to mildew, which is very harmful to the chickens after eating.

The correct feeding method is to add more and put less, and then add more material after the chickens have finished eating. If the chickens can't finish eating, they should be cleaned out of the trough in time.

Six, chicken breeding management

1, illumination

With the increase of chicks' age, the illumination time should remain the same or decrease slightly, and cannot be increased; 1-3-day-old chicks have poor eyesight, and 22-23 hours of light can ensure the chicks to eat and drink, and then gradually reduce it for 20 minutes every week until 9 hours of light every day until 20 weeks old; Indoor lighting can be calculated as 30 watts/10m2.

2. Ventilation

Good ventilation should be maintained in the henhouse, and bacteria, viruses and dust in the henhouse can be discharged through ventilation; Using natural ventilation to realize indoor and outdoor air exchange.

3. Grouping

According to the size and strength of the chicks, the chicks are grouped and adjusted every half month. To control the density of chicks, if the density is too high, chicks will grow slowly and peck easily.

4, disease prevention

Breeding chicks should follow the principle of "prevention is more important than cure"; Vaccination is an important means to prevent chicken diseases; The common immunization procedures for chickens are: 1 day-old Marek's vaccine injection; 10-day-old vaccinated with chicken bursal vaccine for drinking water; 15-day-old chicken Ⅱ vaccine is given nasal drops or eye drops or drinking water; 2 1 day; Drinking water with chicken bursal vaccine at the age of 35 days; 40-day-old chickens were given H 120 mixed drinking water with II vaccine and infectious bronchitis.
