[Preparation work before brooding]
Before hatching, the young house should be completely and thoroughly disinfected. First flush the floor and walls, then use 0.3% of the strong disinfectant solution, 0.5% 100% poison solution or 3% caustic soda solution to spray disinfection, completely kill various viruses and bacteria. The well-closed brooding house is treated with fumigation for 20 hours per square meter of potassium permanganate and 40 ml of formalin for 1 hour. The feed tank, waterer, and other utensils can be placed in the brooding house during fumigation. Disinfection at the same time, open the doors and windows after disinfection, let the air convection for 1 day. After the brooding house has been sterilized, non-sterile utensils are prohibited from moving into the house to avoid recontamination.
[choose healthy chicks to raise]
Regardless of whether or not chicks are hatched or purchased, individuals must be selected. The criteria for selection are: clean anus, no yellow-white dilute fecal adhesions, good umbilical cord absorption, no blood marks, good abdominal contraction, not a large belly chicken, eyes, eyes, Legs, claws, etc. are not deformed. All those who meet the four criteria are healthy chickens; one of the criteria is not met and cannot be used because the weak chicks have low survival rates and slow growth rates and are not suitable for keeping.
[Ensure proper brooding temperature and humidity]
To improve the chick brooding survival rate, it is necessary to create a good living environment for the chicks, in particular, have appropriate temperature and humidity. First-born chicks require higher temperatures: During the first week of brooding, the temperature is between 33°C and 35°C, and afterwards it falls by 2°C per week. After about 6 weeks, the chicks can adapt to the natural environment. If the temperature is appropriate, it cannot be measured by a thermometer. It is important to look at the performance of the chicks to see how the chicken heats. The temperature is too high, the chicks spread out, gasping for breath, loss of appetite, and increased drinking water; the temperature is too low, the chicks are disturbed by sleep, and buzzing sounds, often crowded together, or even plucked together. The long time causes a large number of chicks to die phenomenon. When the temperature is appropriate, the chicks are lively, eating normally, and in good spirits. Practice has proved that maintaining a proper brooding temperature has significant effects on controlling the occurrence of white plague and coccidiosis in chicks, promoting the absorption and utilization of yolk sac, and improving the survival rate of chick brooding. The humidity of the brooding house should be indicated by a dry hygrometer. If it is too high or too low, it is not suitable for the growth and development of the chicks. The ideal humidity is maintained at 60%-70% in the first week and 55%-60% after the second week. If the humidity is too low, the house dust and feather dust are flying high, the chicks are susceptible to respiratory diseases, and the feathers are stunted; when the humidity is too high, harmful gases increase, which is beneficial to the survival of pathogenic microorganisms and the development of parasite eggs. The chicks are susceptible to various diseases. disease.
[Supply sufficient drinking water]
Traditional chicken farming in rural areas often does not dare to give chicks drinking water. It is said that chicks drinking water can cause chickens to diarrhea. In fact, after hatching, chicks should be given drinking water when they enter the brooding house, and penicillin should be added to each drinking water for 1,000 units in drinking water. After 2 hours, 3% brown sugar water should be consumed. Afterwards, warm water can be used instead. Add the appropriate amount of concentrated vitamin B solution. In addition, to prevent shortage of water and intermittent water supply, drinking water should be continuously available and free to drink at any time. Water shortages and intermittent drinking water will cause chickens to become thirsty and cause water rushing, which can easily cause chickens to drink and cause death. Another consequence of water robbing is the phenomenon of many chicks getting wet and getting cold and crushed. If they are not discovered in time, it will cause undue losses.
[Seriously grasping the feeding of chicks]
When one-third of chicks have a search for food, they can eat it. It is usually eaten within 24 hours after being shelled. Feed the chicks to do: feeding the full-price compound feed, regular ration, the feeding times are generally fed seven times a day for the first two weeks, six times a day for three or four weeks, five times a day for five weeks, and six Feed four times a week after the age; as the chicks have poor digestion, they should not overfeed. Excessive food can cause indigestion and cause digestive diseases, so you can feed 80% full. From the 3rd week onwards, appropriate amounts of clean, fine sand can be fed into the feed for chicks to gradually increase the digestive capacity of the chicks.
[ensure proper breeding density]
Reasonable breeding density is an important condition for guaranteeing healthy chickens and good growth, because the density is directly related to the air, humidity, hygiene, and the occurrence of evil fleas in the brooding house. When the chicks are kept at a high density, the air in the brooding house is Dirty, large ammonia smell; high humidity, poor sanitary environment, eating congested; looting water to grab material, hunger and food inequality, the number of deceased chicks increased, serious evil, prone to disease. Low hatching density of chicks is beneficial to the growth and development of chicks, but it is not conducive to the full use of equipment and the rational use of labor. Therefore, the smaller the chicks' breeding density is, the smaller the better. The general situation is 30 in the first week per square meter, 25 in the second week, 20 in the third week, 15 in the fourth week, and 10 or so in five or six weeks.
"Good chicken disease prevention and deterrence"
After the chicks enter the brooding house, use 0.01% potassium permanganate solution as the chick's drinking water to disinfect the gastrointestinal tract. Broilers are more prone to salmonellosis in the early brooding period. Salmonella disease can be prevented by the use of a bacterial enemy (2 millilitres of bacteria added to the enemy by 1 kilogram of clean drinking water). Chicks are susceptible to coccidiosis after 15 days of age, and the use of ball-killing liquid (1 kg of clean water added to 5 ml of ball-killing liquid) can prevent the occurrence of coccidiosis. When chicks are affected by stress factors, 60 mg of succinate can be added to 1 kg of feed for 10 days, or 5 mg of vitamin K can be added to 1 kg of feed to effectively relieve stress. In addition, preventive deworming is carried out once a month, in particular to repel aphids. Drugs such as fleas, insect repellents or insect killers may be used.
