How to raise chickens to improve the survival rate of chicks

Chicken brooding is the key to the success or failure of the chicken industry, which directly affects the health status, survival rate and feed-meat ratio of medium and large chickens. Most of the rural professional farmers do not pay enough attention to the success or failure of the chicken brooding stage. Before the fence house is disinfected, the brooding house should be thoroughly disinfected. First, wash the floor and wall doors and windows with washing powder water, then open the doors and windows to let the natural wind dry, and then spray and disinfect them comprehensively with 0.5% chlorotoxin solution. Finally, spray disinfection with about 10% caustic soda solution (where conditions can be used to spray disinfection with unboiled lime water). After disinfection, wash the drinking fountains, pots and other utensils with disinfectant and put them into the nursery, seal the doors and windows, and fumigate for about 24 hours with 30ml formalin and 15g potassium permanganate per cubic meter of space. To prevent early infection with Marek's disease. Chick selection due to the continuous development of the chicken industry, the brands of the same type of chicken breeds are also diversified, and the prices of chicks of each brand are also different, so it is necessary to identify the brand and price of chicks when choosing chicks, so as to prevent inferior quality or impersonation of brands, resulting in unnecessary economic losses. Choose morning and evening in hot days and noon in cold days. The car for transporting chicks should be well ventilated. When picking up chicks, you should choose healthy chicks with bright hair, lively, cheerful, bright eyes, sensitive response, clean anus, good umbilical cord absorption, pecking, eyes, legs and claws. The survival rate of weak chicks is low, the growth rate is slow, and it is easy to bring viruses. It is best to raise weak chicks separately and eliminate those weak chicks that have no feeding value as soon as possible.

Drink water and buy chicks with boxes scattered in the brooding room to rest for 5 to 10 minutes, and then put them on the ground or on the Internet. Timely use warm water and an appropriate amount of broad-spectrum antimicrobials to make the chicken's first drinking water in order to disinfect the gastrointestinal tract and clean up the bacteria in the gastrointestinal tract. Then drink 10% to 15% glucose water or normal saline. When the chicks are looking for food, they can eat and spread the feed flat on the pad. Because the digestive tract volume of the chicks is small and the digestive function is poor, it can not be excessive, which will cause indigestion and is prone to digestive tract diseases. It is required to add less frequently, and there should be enough space for chicks to feed freely (to prevent chicks from squeezing each other to death). Feed requires rich nutrition, fine particles (broken material), and crude protein should not be less than 20%. Chicks grow fast and have a strong metabolism, so it is necessary to ensure adequate free drinking and feeding. As the chicks are in a high temperature environment, intermittent drinking water will make the chicks thirsty and cause the chicks to grab water, cause the chicks to drink too much and lead to death, and the lack of water is also prone to dehydration and death. Temperature and humidity control to improve the survival rate of chicks, it is necessary to regulate the temperature and humidity. Low temperature is prone to colds, diarrhea, salmonella, ascites, chicken pullorum. High temperature can easily cause hair coke, stagnation of growth and development, dehydration and death. Humidity: 75% in the first week and 60% in the second week.

Temperature: keep it around 35 ℃ in the first week (can be adjusted according to the ambient temperature). After that, it decreased from 2 ℃ to 3 ℃ per week until the chicks could adapt to the natural environment temperature. The temperature can also be regulated according to the state of the chick: if the temperature is too high, the chick will gasp away from the heat source, reduce appetite and increase drinking water. The temperature is too low, often crowded together, huddled with each other, huddled for too long will cause a large number of chicks to be crushed to death. When the temperature is normal, the chicks eat normally, lively and energetic. Lighting, density and ventilation for the first to ten days, chicks require 24 hours of light to familiarize themselves with the environment and feed. Hang a 40-watt bulb 2 meters above the ground with a 40-watt bulb every 15 square meters, and then use a 25-watt bulb and natural light. The light should not be too strong, first, it can reduce the formation of pecking fetish, and second, it can let the chicks develop regular exercise, feeding and sleeping time, which is beneficial to the nutrition absorption and transformation of chickens in the breeding and fattening stage. Excessive light can easily lead to mutual anal pecking, feather pecking and toe pecking. The density should be moderate, the density is a waste of labor, the density chicks are easy to squeeze each other when feeding and drinking water, and the weak chicks have no water to eat. There is no suitable space for exercise. Chicks in the hot growth environment should pay attention to ventilation, so as not to cause respiratory diseases and other diseases prematurely.

Experience summing up when the chicks are raised for 5 to 6 days, the weak chicks are selected and carefully cared for. The temperature can be increased by 2 ℃ to 3 ℃ (until the weak chicks are at the right temperature). Add appropriate amount of broad-spectrum antimicrobials and vitamin C to drinking water for 3 days, and then add appropriate amount of multi-vitamin premix to drinking water for 3 to 5 days. Timely vaccination, out-of-shell chicks should be vaccinated within 24 hours to prevent Marek's disease infection. From 3 to 5 days old, the kidney transmission vaccine was first exempted. At the same time, do a good job of bursa of Fabricius, Newcastle disease, avian influenza, mold and laryngotracheal vaccination.
