How to lay a hen
From the beginning of hatching to 6 weeks of age, the chickens in this growth stage are called chicks. The quality of chicks is not only affected by the growth and development of the chicks but also the brooding rate. It also affects the uniformity and pass rate of the broilers and post-opening production performance. The play. Brooding should do the following work:
1. Prepare before entering the chicks Rinse thoroughly before brooding, sterilize the brooding room and brooding cage, food trough, drinking fountain, etc. Closed doors and windows can be disinfected with 28 milliliters of formalin + 14 grams of potassium permanganate per cubic meter of space, and the temperature of the room is fumigate at 20°C for 24 to 48 hours. After the fumigation is completed, the windows are opened for more than 12 hours and then closed for use.
2. Control the temperature and humidity of the brooding room When the broiler body temperature regulation function is poor and the temperature and humidity are regulated, it is necessary to keep the humidity of the broiler room temperature stable and even, and the height is suitable, and the temperature can be gradually reduced as the age increases. . The first 3 days 34 °C, 4 ~ 7 days 33 ~ 30 °C, from the second week, a drop of 2 °C per week, that is, 1 °C every 3 days, until room temperature. Whether the temperature is appropriate, in addition to looking at the thermometer in the brooding room, we must constantly observe the mental status and activity performance of the chickens so that we can “see the young Shi Wenâ€. The temperature is too high, the chicks are far away from the heat source, the wings are open, the neck is open and the gasps are frequent. When the temperature is too low, the chicks get together and approach the heat source and scream. When the chicks are cold, they are squeezed to make a pile.
The general requirements for relative humidity are 65% for 1 week, 60% for 2 weeks, and 55% for 3 weeks. If the humidity is too high, the remaining egg yolk in the abdomen is not easily absorbed, and it is easy to cause some infectious diseases and parasitic diseases. Low humidity can easily cause respiratory diseases in chicks. In general, the initial humidity should reach 60% to 65%, after which it should reach 50% to 55%.
3. The appropriate density of inbreeding quantity should be determined according to the area of ​​the chicken house, the appropriate density is: 0 to 6 weeks old, average 20 to 24 per square meter, 6 to 18 weeks old 10 to 14, 18 to 20 weeks old 8 to 10 only.
4. Proper ventilation ventilation The metabolism of chicks is strong, the amount of oxygen required and the amount of carbon dioxide emitted are large. Decomposition of feces also produces large amounts of harmful gases such as ammonia and hydrogen sulfide. If the ventilation in the house is poor, it will cause high levels of harmful gases in the house, inducing respiratory diseases, and even blinding the chicks. When ventilating, pay attention to ventilation after the temperature increases, and avoid the invasion of thieves.
5. It is generally 6 to 10 days old to cut off and cut off at the right time. In principle, the sooner the better. The site of the broken jaw was from the tip of the mouth to 1/2 of the nostril, and the lower mouth was cut off by 1/3. Points for Attention: 1 Accurate position, rapid movement, and prevention of massive bleeding. 2 lean or sick chicken, do not rush to break. 3 Vitamin C or hemostatic drugs should be added to the feed or drinking water 2 days before cutting off; 4 Within 1 week after breaking, increase the feed thickness in the feed chute to prevent the chicks from pain or infection due to hollowing wounds; The chicken is given medication inside.
6. Do a good job of immunization and disinfection Based on the principle of prevention, there are strict immunization plans and disinfection measures. According to the immunization program, active immunization, different days of vaccination with different vaccines, have a good immune effect on the corresponding disease. Cleaning inside and outside every day, the water dispenser should be washed every time it is changed, and alternately disinfected with different disinfectants.
7. Feed and nutrition for chicks The growth and development of chicks is fast and the digestive function is not perfect. Therefore, according to the breed standards of each species, formulate the feed formula reasonably. To keep up with the full price, high efficiency, low consumption, digestible feed, maintain the normal growth and development of chicks.
