Ten tips to improve the survival rate of chicks
2020-12-15
The survival rate of chicks is closely related to the income of farmers. Only by learning more and mastering more breeding skills can we ensure a high survival rate and fast growth of chicks.
1. Strict disinfection
Prepare the brooding room before picking up the chicks. Rinse the feeder and drinker thoroughly with clean water, then scrub with hot alkaline water, rinse with clean water and dry for later use. Rinse the brooding room with clean water, lay the bedding after it dries, put in the brooding utensils, fumigate and disinfect with 28ml formalin, 14g potassium permanganate, and 14ml water per cubic meter of space. After 12 to 24 hours, open the doors and windows to ventilate, and preheat the room temperature to above 30°C to receive the chicks.
2. Choose Kindling
Healthy chicks are generally lively and active, with strong legs, free movement, clear eyes, and good umbilical healing. Weak chicks have filthy feathers, are depressed, doze with closed eyes, and stand unstable. Be sure to choose healthy chicks when buying chicks.
3. Drink water in time
The chicks can lose 8% of water within 24 hours and 15% within 48 hours. When the water loss is greater than 15%, symptoms of dehydration will soon appear. Therefore, the chicks should be provided with adequate and clean drinking water 12 hours after they emerge. Drink 0.01% potassium permanganate and water added with multivitamins in the first few days to disinfect drinking water and clean up the stomach and intestines, and promote meconium discharge.
4. Careful feeding
The feed should have good palatability, easy digestion, fresh quality, and moderate particle size. The chicks can be fed within 12 to 24 hours after they are out of their shells. They can be started with crushed corn, millet, broken rice, crushed wheat, etc., and boiled until they reach eight maturity for feeding, which is beneficial to the digestion of the chicks. Feed 6 to 8 times a day and night for 1 to 3 days of age, 4 to 5 times a day after 4 days of age, and 1 time at night. Gradually change the feed to the chicks.
5. Adjust temperature and humidity
The suitable temperature for raising chicks is: 30℃~32℃ at 1 week of age, 28℃~30℃ at 2 weeks of age, 25℃~28℃ at 3 weeks of age, 22℃~25℃ at 4 weeks of age, every week thereafter Lower the temperature by 1.5℃~2℃, and keep the humidity at 60%~65% within 1 week of age, and 50%~60% after 1 week. If the chicken house is too wet, you can put some quicklime in a cloth bag to absorb moisture; if it is too dry, you can put a basin of water on the stove to increase the indoor humidity through water evaporation.
6. Reasonable density
The size of the density should be adjusted reasonably according to the age of the chicks, the breeding method of the breed and the structure of the chicken house. The reasonable density of general breeding chicks is: 0~4 weeks old is 20~25 per square meter; 5~7 weeks old is 10~20. The reasonable density of online brooding is: 0~4 weeks old is 24~28 per square meter, 5~7 weeks old is 15~20.
7. Scientific illumination
The reasonable light time is: 0~3 days of age 24 hours, 4~14 days of age 16-19 hours, after 15 days of age, use natural light. The light intensity is per 15 square meters of chicken house in the first week, with a 40W light bulb suspended at a height of 2 meters, and it is enough to switch to a 25W light bulb from the second week.
8. Hygiene and epidemic prevention
An unsanitary and humid environment is likely to induce disease in chickens, especially pullorum and coccidiosis. The chicken house should be thoroughly disinfected regularly, kept dry and clean, bedding should be changed frequently, drinking water should be clean, and feed should be fresh. Chicks were injected with 0.2 ml of freeze-dried Marek’s disease turkey herpes virus vaccine for the first immunization. Add 5% glucose, 0.1% vitamins, penicillin and streptomycin in drinking water. Add 0.02% furterine to drinking water for 2~7 days, and mix 0.1% chloramphenicol in feed. At the age of 5 to 7 days, use Newcastle disease II or IV vaccine in the prescribed dose to instill the eyes and nose. Marek's vaccine was injected subcutaneously at 14 days of age for the second immunization. The bursitis vaccine was injected at 18 days of age. At the age of 30 days, they were immunized with Newcastle disease II or IV vaccine for the second time. If sick chickens are found, they should be isolated and treated in time, and dead chickens should be burned or buried deep away from the chicken coop.
9. Fresh air
Strengthen the ventilation of the brooding room and keep the air in the house fresh. Ventilation in the house can be carried out at noon when the sun is full, and the opening of the doors and windows is half open from small to large. Do not open the doors and windows suddenly, let the cold wind blow directly, and make the room temperature suddenly drop.
10. Careful management
It is necessary to observe the flock frequently and grasp the dynamics of the flock. Reduce stress factors and strictly prevent cats and mice from entering the chicken house; check the house temperature at any time, if the temperature is too low, the chicks will get crowded and crushed; if the chicks are pecking anus, apply purple potion on the pecking place; 7~11 days old should be timely Cut off the beak, use the beak cutter to cut off 1/2 of the upper beak and 1/3 of the lower beak of the chicks. Two days before cutting the beak, add an appropriate amount of vitamin K3 (20-30 ml/kg body weight) and antibiotics to prevent bleeding , Slow down the stress response of beak breaking.
