Healthy chicks are the first step towards the success of aquaculture, and the most crucial step. How to breed brooding scientifically and efficiently has caused more and more attention and attention from the majority of farming practitioners. According to many years of experience, scientific brooding must take seven good points:
1. Disinfect before entering the chicken cage
Thoroughly remove organic matter before disinfection. Excessive organic matter will affect the disinfection effect. Do not rush to clean after spraying the disinfectant. Wait for a period of time to make contact with the bacterial virus and then wash it. The fumigating time must be long enough. Ensure that the gas is fully volatilized, so as to avoid damage to the respiratory mucosa of the chicken after entering the chicken battery cages. If the chickens in the previous batch have a strong infectious disease, they should be fumigated and disinfected at the same time.
The brooding start temperature is 34 to 32 degrees, the temperature of the chicks should be low, and the temperature of the weak chicks should be high. After that, it will fall steadily by 2 to 3 degrees every week until it is stable at around 21 degrees. The temperature is kept constant to avoid large fluctuations in temperature difference. The thermometer is evenly distributed in the house and can be adjusted at any height so that the bottom of the thermometer is at the same height as the chicken back. Learn to watch the flock status Shi Wen: evenly distributed, comfortable, suitable for temperature; away from the heat source, open mouth to breathe, the temperature is too high; close to the heat source, squeeze the pile does not love moving, the temperature is low.
One week old chicks require higher air humidity and a suitable relative humidity of 65% to 75%. Dry air causes dehydration of the chicks, dry skin, dry chicken feet, and prone to respiratory diseases. In the 1-2 weeks of the brooding house, a kettle is placed on the stove to evaporate the humidified air, and vinegar is also available. The high temperature and high humidity environment makes the chicken difficult to dissipate heat, and the heat and humidity are uncomfortable. The low temperature and high humidity environment accelerates the heat dissipation of the chicken, the cold is cold, and the resistance is reduced. Too much coagulopathy, chicken white sputum and colibacillosis are common in the house.
4. Chicken raising density
The number of chicks should be determined according to the area of the house. If the density is too large, the growth will be slow, the time for slaughter will be prolonged, the size will be differentiated, the ratio of meat to meat will increase, and the income will decrease. Too small a density reduces the utilization of the house. Chicken hour chicken house is sufficient area, it is appropriate to enlarge the feeding area properly, although more heating costs, but the growth is rapid, even and neat, more profitable chicks when the density is large, need to expand the shed in time, especially in winter: 1 ~ 2 weeks old, 30 / m2, 3 ~ 4 weeks old, 20 / m2, 5 ~ 6 weeks old, 12 ~ 15 / square.
