Three points for brooding

First, broiler sterilisation can only give chicks a safe and healthy environment in order to have a good start. The disinfection of the shed is divided into four steps, the first step, cleaning. Clean up the chicken waste in the house, including dirt, dust, etc. thoroughly. Many diseases are transmitted through chicken dung, such as the bursa of Fabricius and the flu. The second step, wash. Rinse the equipment and the ground with clean water. The conditional use of a high-pressure pump is better. The third step is disinfection. One meter below the ground and wall with 2% caustic soda, and then spray with iodine-containing disinfectants, such as gold iodized Wei, Bao iodine and so on. Because iodine is more sensitive to bursal disease virus. The fourth step is fumigation. Smoke is everywhere, disinfection is more thorough, the most commonly used is sea riding smoked tyrants, that is, the economic effect is good.

Second, picking good chicks can be cured, but bad chickens are difficult to maintain. High quality and healthy chickens are derived from the purification, nutrition, management and incubation techniques of the flock. A variety of diseases (respiratory syndrome, glandular gastritis, mycoplasma, E. coli, Salmonella, etc.) can be transmitted through the deciduous egg, and factors such as yolk inflammation, umbilical cord inflammation, and dehydration also directly affect the survival rate. How to choose chicken?

1, see the color Under normal circumstances, the chick hair brown red or golden yellow, the darker the color that the better the yolk absorption.

2, see the weight of the chicken body out of the shell, the greater the weight later.

3, see the absorption of yolk If individual chicken abdominal enlargement, umbilical no villi, umbilical cord is not broken, there is bloody water, anal with white lime-like feces, can be judged as unhealthy chicks.

Third, improve the survival rate of brooding

1. The bigger the humidity in the first three days, the better, the relative humidity is preferably 80-85%, the first 4-6 days, the relative humidity is 60-65%, the humidity should be reduced after one week, and the ventilation should be strengthened to reduce the occurrence of coccidiosis. It must be remembered that "ventilation and ventilation are a treasure, no medicine can substitute for it" and poor ventilation is the root cause of all diseases.

2, a few days ago, the temperature of the water for the chicken to control at 18-21 °C, chicks refused to drink more than 30 °C warm water. 3. It is very important to improve the evenness of broilers and it is also one of the most important factors to measure success or failure. There are many reasons for poor uniformity (such as too much density and groups, too few diseases, drinking water and feeding equipment, etc.) Some chickens cannot drink water on the first day and must become weak chicks. For this reason, many experienced chicken farmers do not put chicks directly into the brooding cage. Instead, they hold their heads to peck their mouths in the water and teach all chickens to learn to drink water at the same time. This will increase uniformity. Is very important.

4. Don't hope to let every breeder farm hatch hatchlings that don't carry germs. It is impossible to do this. (The problems encountered by the chicks within a week are: umbilicitis, yolk phlegm, white peony, typhoid, paratyphoid Mycoplasma, E.coli, Staphylococcus, Streptococcus, etc.). Since this is the case, the disease prevention work should be done as early as possible. The following principles should be followed in the use of chickens: a. The drugs that damage the kidneys should not be used (such as streptomycin, Qingda, Kana, etc.) b. Try to give it water and avoid mixing it. Because the mixing is not uniform, it can cause poisoning. In addition, the diseased chicken eats less, and the healthy chicken has a large feed intake, which does not provide therapeutic effects.

5, chickens hatched after the kind of chicken farms should promptly do drug susceptibility testing, guide chicken farmers medication, because the breeder used some antibiotics, chicks will not be sensitive to reuse. There is also a drug on the farm that is not sensitive to this reuse. The safest method is to use high-sensitive antibiotics in the first 5 days after hatching. Although the price is higher, the chickens drink less water, the cost is not high, and more importantly, the effect is exact, laying the foundation for future growth and development. A good foundation
