Because chicks have the characteristics of poor body temperature regulation, rapid growth, strong metabolism, poor digestion, and poor disease resistance, in order to improve the survival rate of chicks, we must start from the management, pay attention to disinfection, temperature, humidity, density, With regard to disease prevention and immunity, I believe that the reasons for the survival rate of chicks are as follows:
1. Disinfection is not strict. Before entering the chicks, the chicken house was not thoroughly cleaned and flushed, and it was not fumigated and disinfected. It only took 1-2 times with the disinfectant solution to feel good peace of mind, leaving the pathogenic microorganisms for a long time. The chicks were susceptible to E. coli and Staphylococcus infections.
2. The temperature is not suitable. Before entering the chicks, the preheating in the house is not enough, causing the chicks to get together and squeezing 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, the chicks are vulnerable to cold, resulting in diarrhea, dehydration, will affect the yolk Absorption.
3. The air does not circulate. When brooding in winter and spring, the light is thinking of keeping warm, and neglecting proper ventilation and ventilation, resulting in high ammonia and carbon monoxide content, which can easily cause respiratory symptoms and even poisoning.
4. Overfeeding. It is possible to raise 1,000 broiler houses and enter 100 more when they enter the nest. It is calculated that even if 100 wounds can be kept, only 1000 can be kept. It is because of the overfeeding that the chickens have high density and it is not easy to observe the condition of the flock. The development is irregular, the air is not good, the disease spreads quickly, and it leads to higher mortality.
5. The drug died. After entering the chicks, it is not the use of suitable chicks for the prevention of diarrhea, but the use of antibiotics in large quantities, regardless of the size of chickens. Some even use antibacterial drugs diluted with 200 kg of water, which are used up in a few days and aggravate the liver. Kidney burden, causing death.
6. Not immunized in time. As long as the chickens are found to have respiratory symptoms, they have been using antibiotics and have even delayed secondary infections such as Newcastle disease and infectious bursal disease, leading to an outbreak of infectious diseases. In addition, when the chicks enter the chicks in the fall, they do not attach importance to the advance prevention of chicken pox vaccines. They also wait until 60 days or 120 days for stabbing, and there is a serious chickenpox disease, especially throat-type chicken pox.
7. Insufficient disease control. Because of the incomplete purification of vertically transmitted diseases such as chickens and mycoplasma in breeder farms, it is easy for weak chicks and sick chicks to die. Last winter, 20-30 days old chicks developed infectious bronchitis this spring. Due to the small age and the large amount of dust in the house, the yellow trachea easily formed in the trachea and bronchus died of suffocation, resulting in long illness and death. The rate is high and the effect of medication is poor.
8. Faults do not meet the requirements. When discomfort occurs, the ratio between the upper and lower parts is not appropriate when they break or break, causing the birds to lick each other and cause excessive blood loss resulting in death.
Countermeasures: Before brooding, clean the brooding room first, rinse and sterilize after rinsing. The brooding room is preheated 2-3 days in advance, and room temperature is 33°C-35°C within 1-3 days, then it is 2°C lower every week, and the correct choice for preventing white lice is recommended. Drugs such as coccidiosis, with appropriate dosages, timely immunization, debriding, ventilation, and avoiding artificial overdose, epidemic outbreaks, bruises, and carbon monoxide poisoning, can only be raised by science to improve the survival rate of chicks. To benefit farmers.
