Chick Survival rate relationship benefit Multi-skill to improve Chicken Survival rate

The survival rate of chicks is closely related to the income. Only by learning more chicken breeding skills can we ensure the high survival rate and fast growth of chicks.

Chick

1. Strict disinfection: prepare the brooding room before picking up the chicks. Wash the feed trough and drinking fountain thoroughly with clean water, then rinse with hot alkaline water, rinse with clean water, and then dry. Clean the nursery room with clean water. After drying, spread the bedding grass, put into the brooding utensils, fumigate and disinfect the chicks with 28ml formalin, 14g potassium permanganate and 14ml water per cubic meter, close the doors and windows for 12 hours and then open them, ventilate and preheat the chicks to more than 30 ℃ at room temperature.

two。 Choose healthy chicks: healthy chicks, lively and active, strong legs, free movement, eyes, good navel healing. Weak chicks have dirty feathers, low spirits, snooze with their eyes closed and unsteady on their feet. When buying chicks, choose healthy chicks.

3. Timely drinking water: the chick can lose 8% water within 24 hours after coming out of the shell. 15% water loss in 48 hours. When the water loss is more than 15%, the chick will soon develop dehydration symptoms. Therefore, adequate clean drinking water should be provided in time 12 hours after the chicken comes out of its shell. In the first few days, drinking 0.01% potassium permanganate and water with multivitamins can clean up the intestines and stomach and promote meconium excretion.

4. Meticulous feeding: the feed should be palatable, easy to digest, fresh, high quality and moderate particle size. The chick will eat within 12 hours after it comes out of its shell. Crushed corn, millet, crushed rice, chopped wheat and so on can be used for eating. Boil to medium well, which is good for chicken digestion. At the age of 1-3 days, they were fed 6-8 times every day and night, 4-5 times a day after 4 days of age, and once at night. Gradually change to feed the chicken mixture.

5. Adjust temperature and humidity: suitable temperature: 30 ℃ ~ 32 ℃ in 1 week, 28 ℃ ~ 30 ℃ in 2 weeks, 25 ℃ ~ 28 ℃ in 3 weeks, 22 ℃ ~ 25 ℃ in 4 weeks, and then reduce 1.5 ℃ ~ 2 ℃ per week until the room temperature and humidity is kept at 60% 65% within 1 week and 50% 60% after 1 week. If the chicken coop is too wet, you can use a cloth bag filled with quicklime to absorb moisture; if it is too dry, you can put basin water on the stove to increase indoor humidity through water evaporation.

6. The density is reasonable: the density should be adjusted according to the chicken age, breed, feeding mode, chicken house structure and so on. The general reasonable density was 25 mice per square meter at the age of 4 weeks and 20 birds at the age of 5 weeks and 7 weeks. The reasonable density of online brooding was 24 per square meter at the age of 4 weeks and 20 at the age of 5 and 7 weeks.

7. Scientific light: reasonable light time: 24 hours at the age of 3 days, 16 hours at the age of 14 days, and natural light after 15 days of age. According to the light intensity, every 15 square meters of chicken coop is hung at a height of 2m with a 40W bulb in the first week, and 25W bulb is used in the second week.

Chicken epidemic prevention

8. Health and epidemic prevention: disinfect the chicken house regularly, keep it dry and clean, change the cushion frequently, clean drinking water and fresh feed. The chicks were immunized for the first time and injected with 0.2 ml Marek's disease turkey herpesvirus freeze-dried vaccine. Add 5% glucose, 0.1% vitamins, penicillin and streptomycin to drinking water. At the age of 2-7 days, 0.02% dysentery was added to the drinking water and 0.1% chloramphenicol was mixed in the feed. At the age of 5-7 days, the chickens with Newcastle disease Ⅱ or Ⅳ vaccine were given eye drops and nasal drops according to the prescribed dose. At 14 days old, Marek's vaccine was injected subcutaneously. 18-day-old bursitis vaccine was injected. At 30 days old, chicken Newcastle disease Ⅱ or Ⅳ vaccine was used. When diseased chickens are found, they should be isolated and treated in time, and the dead chickens should be taken out of the henhouse and burned or buried deeply.

9. Fresh air: strengthen the ventilation of the nursery room and keep the air fresh. Ventilation in the house can be carried out when the sun is sufficient at noon, and the doors and windows are half-open at last. Do not suddenly open the doors and windows and let the cold wind blow directly, so that the room temperature drops suddenly.

10. Meticulous management: always observe the flock and grasp the dynamics of the flock. Reduce stress factors, strictly prevent cats and rats from entering the henhouse; check the temperature at any time, the temperature is too low, causing chicks to be crushed to death; it is found that anus-pecking chicks can apply purple potion at the place where they are pecked. At the age of 711 days, the beak should be cut off in time. The upper beak of the chick was cut off with a beak breaker. Two days before the beak was cut off, proper amount of vitamin K3 (20ml / kg body weight) and antibiotics could be added to the feed to prevent bleeding and slow down the stress reaction of beak cutting.
