Five points should be paid attention to in raising broilers in winter

The weather in winter is cold, the chicken house is dry, and the ventilation is poor, so we should pay special attention to it. For this reason, we summarize five points for attention for raising broilers in winter. The details are as follows:

Disinfection of chicken farm

First, heat preservation and cold protection, do not forget ventilation.

It is cold in winter, and the temperature in the house is very different from that in the outside world. It is necessary to ventilate and keep warm, which is the most important problem to be solved. The chicken house has good cold protection performance, which can meet the requirements of winter heat preservation. Strictly prevent chickens from being squeezed to death due to low temperature.

In ventilation, the temperature should not be high and low, strictly prevent diseases caused by stress caused by excessive temperature difference, the vent should be more than 1.5 meters above the back of the chicken. When the temperature drops sharply and the heat preservation work can not keep up, it is easy to make broilers feel cold, cough, sneeze, trachea rales, breathing difficulties and so on. Therefore, it is necessary to master climate change and do a good job of cold prevention and heat preservation. The chicken coop should be well maintained to prevent thieves from invading the flock. Broilers raised on flat land should thicken the bedding and use it to increase the room temperature. Change the cushion frequently and open the window at noon for ventilation. In general, ventilation begins at the age of 6 days, and with the increase of age, the ventilation rate is increased to make the chickens have enough oxygen.

Second, keep warm and dry, do not forget to discharge ammonia.

Ventilation should not be ignored in order to keep the henhouse warm in winter. The feces and wet bedding of chickens were not removed in time, resulting in the accumulation of ammonia in the house, the increase of concentration, and other diseases such as ammonia poisoning in broilers. In order to prevent the adverse effects of ammonia, watering should be reduced as much as possible during operation, and water leakage in the waterproof trough should be reduced. If the humidity of the chicken house is too high, the feces and wet padding should be removed in time. In addition, ammonia deodorant can be used to reduce the concentration of ammonia in the chicken house, such as copper sulfate, ferrous sulfate, perphosphoric acid, hydrated lime and so on.

Third, strengthen feeding, do not forget disease prevention.

According to the different growth stages of broilers, the diet was prepared according to the feeding standard. The low temperature in winter and the high calorie consumption of broilers can appropriately increase the standard of metabolic energy in feed and reduce the proportion of protein appropriately. At the same time, attention should be paid to the content of vitamins in diet to meet their needs. The raw grain of the feed shall be free from mildew and impurities.

To do a good job in disease prevention, when the physique of broilers is weak and their resistance decreases, some diseases may occur and respiratory diseases may occur. Therefore, while improving the resistance of broilers, we should do a good job in disease prevention and treatment. Vaccination should be carried out in strict accordance with the immunization procedure. Drugs to prevent diseases are usually used. Disinfect the henhouse regularly.

Fourth, to strengthen management, we must not forget the routine.

Before entering the brood, strictly scour, disinfect and fumigate the nestling house. Thoroughly clean utensils, clothes, hats, houses, etc. Control drinking water, generally drinking water is 2-3 times of material consumption, but it is not suitable to supply more water, because more water will aggravate the dampness of cushion materials, and prevent water running when using water pipes. Broilers raised on the Internet are prone to respiratory diseases, especially about 25-day-old broilers in winter. The disease is mainly caused by dry air, too much dust, poor ventilation, inhalation and long-term accumulation of chickens. Prevention and control measures: maintain the temperature in the house and increase the ventilation rate to ensure the oxygen content in the house.

Fifth, environmental control, do not forget hygiene.

First of all, introduce chicken seedlings from healthy breeding farms to strictly prevent the introduction of pathogens. Secondly, create a good breeding environment. Strict distinction between breeding utensils and disinfection utensils, and regular disinfection, at the same time regularly monitor the adjacent chicken farms and local areas for disease epidemic situation, take preventive measures. Regularly monitor the health status of broilers in this farm, appear epidemic situation, and deal with it in time. Disinfect chickens, eliminate rodent damage, burn dead chickens, and isolate sick chickens from healthy chickens.
