The relationship between chicken quality and chicken benefit matters needing attention in raising chicks in spring

Chick

First, strict disinfection. Prepare the nursery before picking up the chicks. Feed troughs and drinking fountains are first washed and disinfected with hot alkali water or 0.2% potassium permanganate water, then rinsed with clean water and dried. Before brooding, the brooding room should be thoroughly cleaned, closed doors and windows, bedding, and paraphernalia, fumigating with 14ml formalin, 7g potassium permanganate and 7ml water per cubic meter, opening doors and windows for ventilation after 24 ℃ 36 hours, preheating room temperature to more than 30 ml.

Second, select healthy chicks. The healthy chick is lively and active, the legs are strong, the movement is free, the eyes are bright, and the navel heals well. Weak chick villi dirty, umbilical blood, yolk absorption is not complete, spirit is dispirited, close eyes to nap, stand unstable. When buying chicks, be sure to choose carefully.

Third, keep warm and adjust humidity. The development of chicks is affected by sparse villi, poor heat preservation, cold resistance, too high and low humidity. The optimum temperature for raising chicks was 32 ℃, 32 ℃ at 1 week, 28 ℃ at 2 weeks, 25 ℃ at 3 weeks, and 25 ℃ at 4 weeks, and then decreased by about 1.5 ℃ per week. The temperature should be balanced, not high or low, and the thermometer should be hung at 10cm above the active position of the chicken. If the temperature is suitable, the chicks will disperse evenly; if the temperature is too low, the chicks will be crowded into piles. The humidity should be 60% 65% within 1 week of age and 50% 60% after 1 week. If the chicken house is too wet, you can put a cloth bag filled with quicklime to absorb moisture in the room; if it is too dry, you can put basin water on the stove to increase the indoor humidity through water evaporation.

Fourth, drink plenty of water. Chicks can lose water in 24 hours after coming out of the shell. 8% can lose water in 48 hours, and 5%. When the water loss is more than 15%, dehydration symptoms will occur quickly. Therefore, chicks should be provided with sufficient clean glucose and vitamin C drinking water 12 hours after coming out of the shell to clean the intestines and stomach, eliminate meconium and provide nutrition. For chicks within 1 week of age, 2/10000 potassium permanganate was supplied for drinking water, disinfection and sterilization. Keep the drinking fountain hygienic and wash it once a day.

Fifth, rational feeding. The nutritious and comprehensive feed was prepared according to the feed requirements of different breeds of chicks. The chicks were fed within 24 hours after they came out of their shells. Boil the rice into "half-cooked" rice, wash the stickiness of the rice with cold water, make it "raw but not hard, cooked but not sticky, granulated and spread", sprinkle the rice on a clean plastic film or mat to induce chicks to peck freely, feeding 60 or 70% at a time; at the same time, shred fresh lettuce to let chicks peck freely, feeding unlimited amount. Feeding principle: add less frequently, strong and weak chicks are raised separately. Generally, at the age of 1-3 days, the mice were fed 8 times per day and night, and the lights should be turned on at night. At the age of 4-7 days, they were fed 5 times during the day and once at night. After 8 days of age, they were fed 4 times a day, and the last time at 7: 00 pm.

Sixth, the density is suitable. Too high density is not conducive to the growth of chicks; too small density is not conducive to waste space, but also not conducive to heat preservation. In production practice, it is appropriate to raise 50 chicks per square meter, or 30 medium chicks per square meter, or 20 large chicks per square meter.

Seventh, strengthen ventilation. In order to solve the contradiction between heat preservation and ventilation, it is necessary to strengthen the ventilation of the nursery room, which is conducive to keeping the indoor air convective, fresh and clean, without peculiar smell. Windows can be opened for ventilation at noon when there is plenty of sunshine, especially for chicks over 10 days old. Avoid the cold wind blowing directly on the chicken, usually pay attention to guard against the attack of the thief wind.

8. Environmental hygiene. Unhygienic and humid environment is easy to cause chicken diseases, especially white dysentery and coccidiosis. Therefore, the floor of the nursery should be kept dry and all kinds of appliances should be disinfected frequently.

Chicks with broken beak

9. Careful management. We should always observe the flock and grasp the dynamics of the flock. Reduce stress factors, strictly prevent cats, rats, dogs and birds from entering the henhouse; check the temperature at any time, the temperature is too low, causing chicks to pile up and die; found that anus-pecking chicks can be pecked with purple potion, do not apply red potion, because the chicken pecked harder after applying red potion 7Mel 11 days old, the beak should be cut off in time, and the beak breaker should be used to remove the upper beak of the chicks and the lower beak of the chicks. Two days before the beak was amputated, appropriate amount of Vasu K3 (10 Mel 20 mg / kg body weight) and antibiotics could be added to the feed to prevent bleeding and slow down the stress reaction of beak cutting.

Attach importance to epidemic prevention. At the age of 1 day, the chicks were injected with 0.2 ml Marek's disease turkey herpesvirus freeze-dried vaccine for the first time. 5% glucose, 0.1% vitamins, penicillin and streptomycin were added to the drinking water with 1500 units each. 2Mel 7 days old, 0.02% dysentery was added to drinking water, and 0.1% chloramphenicol was mixed into feed. At the age of 7 days, the chickens were immunized with Newcastle disease Ⅱ vaccine or Ⅳ vaccine by eye drip and nasal drip at the prescribed dose. At the age of 14 days, Marek's disease vaccine was injected subcutaneously and the second immunization was carried out. At the age of 18 days, bursitis vaccine was used for the first time. At the age of 30 days, the second immunization was performed by eye drip at the prescribed dose of Newcastle disease Ⅱ vaccine or Ⅳ vaccine. At the age of 40 days, the mice were immunized with bursitis vaccine at the prescribed dose.
