Insufficient management to reduce the survival rate of chicks

First, disinfection is not strict: Before entering the chicks, the chicken house is not completely cleaned, not fumigated, sprayed only once or twice with the disinfectant, making the microorganisms exist for a long time. The chicks are susceptible to E. coli, Staphylococcus, etc., resulting in death.

Second, the temperature is low or change: before entering the chicks, the preheating in the house is not enough, causing the chicks to get together and squeeze to death; the temperature is too high, the chicks have high respiratory intensity, and the loss of water is more; the temperature is high and low, and the chicks are vulnerable to cold. Cause diarrhea, dehydration, will affect the absorption of yolk.

Third, the air is dirty: When winter and spring brooding, only think of insulation, ignoring the appropriate ventilation, air conditioning to keep the house fresh, resulting in ammonia, carbon monoxide content is too high, light respiratory symptoms, severe poisoning.

IV. Overfeeding: Most breeders have excessive feeding phenomenon. They could have kept 1,000 chickens. When they enter the chicks, they will enter 100 more, or they are willing to add more chicks to the hatchery. It is calculated that even 100 wounded animals can be reared. 1000, just to meet the requirements. As everyone knows, contrary to expectations, it is precisely because of over-feeding that the density of chickens is high, it is not easy to observe the condition of the flock, the development is not neat, the air is not good, and the disease spreads quickly, resulting in higher mortality.

V. Drug abuse: After entering the chicks, it is not the use of special drugs for chicks to prevent the disease. It is a biased drug seller who believes that the drug will be used in large quantities, even with antibacterial drugs labeled with 200 kg of water for a few days. After that, heavier burdens on the liver and kidneys caused a large number of chicks to die.

Six, immunization is not timely: after the chickens break, due to stress or poor air, it is inevitable that respiratory symptoms. Some chicken farmers simply stop using drugs as soon as they hear heavy breath sounds, delaying the release of major infectious diseases such as Newcastle disease and Bursa's bursal, leading to the occurrence of infectious diseases. In addition, in the autumn when the chicks do not pay attention to the early prevention of chicken pox vaccine, wait until 60 days or 120 days of puncture chicken pox vaccine, there is a serious chicken pox disease, especially throat-type chicken pox more likely to die.

Seventh, cutting off does not meet the requirements: When discomfort occurs, the upper and lower proportions are not appropriate when they are cut off or cut off, so that the chickens lick each other and lick the anus, resulting in death due to excessive blood loss.

Suggestion: Before brooding, clean and rinse the brooding room before fumigation. The brooding room is preheated for 2 to 3 days in advance, room temperature is 33 to 35°C within 1 to 3 days, and then 2°C is dropped every week. Correct selection and use of white fleas are recommended. Drugs such as coccidiosis, timely immunization, debriding, ventilation and ventilation.
