Winter cold weather and the temperature of the inner need to the temperature difference with the outside world, both to ventilated take a breath, and to keep the inner temperature, that is the main problem to be solved for winter. Hen house requires thermal performance is good, to achieve the requirement of the winter heat preservation.
1.Ventilation and heat preservation of give attention to two or morethings
At the same time of ventilated take a breath, be careful not to cause inner temperature high or low, to fight diseases caused by stress due to temperature difference is too large, the vent above the chicken back above 1.5 meters advisable. When the temperature down sharply, the cold insulation work to keep pace with, tends to make chicken exogenous cold, happens to cough, sneeze, tracheal rale, breathing difficulties and other symptoms of respiratory disease characterized by. As a result, owners to grasp well the change of climate, well thermal insulation work. Hen house to good maintenance, prevent the evil wind, drafts hit the crowd. The ground raising the chicken group to thicken bedding, padding is used to improve the indoor temperature. Generally, 6 days of age began to ventilation, and with the increase of age, increase the ventilation rate, make the chicken group has enough oxygen. If shed compare the foul air in morning, must increase the ventilation rate, should be increased gradually, it is best at noon at high temperature, using each ventilation time short, pass a few times more better way. If it is found that the chicken disease-free 1, breathing, breath, dusty inside henhouse, peculiar smell is very thick, indicated in the hen house air extremely dirty, should immediately to strengthen ventilated. But to prevent evil wind, generally in the leeward side walls set elbow room for action ventilation device, so as to avoid the crowd directly affected by the wind.
2。Don't forget row of ammonia
For chickens excretion of feces and damp bedding is not clear in time, cause the accumulation of ammonia in the henhouse, concentration increases, lead to poultry ammonia poisoning or cause other diseases. To prevent the bad influence of ammonia to poultry, management suggestion raised chicken farm (household) pays special attention to the following: operation to minimize water, prevent water tank leaking; If the humidity within the hen house, should keep clear of in time in feces and the damp bedding. In addition, ammonia absorption deodorant is used to reduce the ammonia concentration of henhouse, commonly used with ferrous sulfate, phosphoric acid, copper sulfate, hydrated lime and so on.
3.Don't forget prevention
According to the different growth phase of chicken, according to the breed standard mixed diet. Due to the low winter temperatures, chicken heat consumption, mixed diet can improve the metabolism of feed can appropriately when standard, and decrease the percentage of protein in the feed, at the same time, it is important to pay special attention to the content of vitamin in the diet, to satisfy their needs. The raw grain of feed must be free of mildew to change, without impurities, in case of cause respiratory disease.
Do a good job in prevention of viral diseases and bacterial disease as chicken physique weaker, resistance to drop, the occurrence of some diseases can be complicated with respiratory diseases. Therefore, at the same time, improve the body's resistance to disease prevention and control work. Have a vaccine inoculation to strictly according to the immune procedure to prevent injection. They're often use drugs to prevent disease. Disinfect hen house on a regular basis.
4.Don't forget the conventional
Before entering the young young fish for strict washing, disinfection and fumigation. Thoroughly rinse appliances, clothes, houses, etc.
Control of drinking water, drinking water is commonly consumption capacity is 2 ~ 3 times, but not much water, because water will add to the padding and damp, when using a pipe to prevent running water.
Online flat raise chicken group of non infectious respiratory disease, often occurred in the especially around the age of 25, chicken is used during the winter. The disease is due to raising the result of poor management, mainly because the inner air drying, dust too much, and in the case of poor ventilation, in the crowd, long-term accumulation and cause disease. Prevention measures is under the premise that maintain inner temperature, increased ventilation volume, in order to ensure the inner oxygen content, chickens is not or less disease pathogenesis, resumed as soon as possible after the basic conditions.
5.Don't forget the health
First of all, should from the healthy kind of farm introduced 40, fight by vertical transmission into pathogens. Second, should create a good breeding environment. Feeding utensils to strictly distinguish, disinfection equipment and regular disinfection, keep a horizontal spread disease, at the same time, regular monitoring of adjacent chicken farms and presence of the happening of the disease outbreaks in this region, take preventive measures. Regular monitoring of the chicken group health, an epidemic process in a timely manner. Third, insisted that take the chicken disinfection, elimination of rat, beware of rat spread disease, burn buried dead chicken processing, sick chicken chicken isolation principle to health.
6.Pay special attention to the gas poisoning
Many farmers through the stove or heater heating the temperature of the henhouse necessary in order to achieve. Scale in the development of real cases, the limited conditions, many farmers in the use of coal heating furnace heater or coal furnace, it is outstanding one must pay attention to the problem - the soot poisoning. Soot is mainly for the carbon monoxide gas, easy to mix carbon dioxide in the henhouse, chickens poisoning caused by harmful gases such as sulfur dioxide.
Poisoning symptoms: chicken coma hesitated, difficulty breathing, mouth breathing, movement disorders, anal relaxation, lie on your side back convulsions and death. Mild poisoning feathers scattered, loss of appetite, thin dung, slow growth. Anatomy of the visible blood vessels and splanchnic blood thin pink, viscera surface have small bleeder.
Good fire prevention: design, warm wind furnace smoke evacuation barrels (furnace), to prevent the smoke leakage, DaoYan, or blockage in a flue. Flue outdoor export must be up above the henhouse apex, prevent the downdraft. Hen house to set up the upper vents (skylight), keep the air flow, to prevent carbon monoxide concentration in the henhouse.
Chickens gas poisoning prevention and treatment: found immediately opened the doors and Windows, ventilation rapidly, as far as possible can use fan, fan speed up the air, put the chicken chicken coops, timely transferred to the fresh air poisoning serious chicken can inject arm, can add in glucose or high quality drinking water cube.
All in all, winter chicken breeding management is a comprehensive work, grasp the key points of each link in the comprehensive consideration, to improve the economic benefits of chickens in winter
