The climate is dry in autumn, the temperature is fickle, the temperature difference between day and night is large, the stress factor is increased, and with the existence of immunosuppressive factors, the resistance of chickens is decreased, the disease is multiple, and the mixed infection is difficult to control. In winter, the cold wind rags, and the insulation of the chicken house is difficult. Poor internal ventilation, high ammonia concentration, and the relationship between insulation and ventilation are difficult to balance; mycotoxins cause immune failure, respiratory diseases, Newcastle disease, flu and other viral diseases, making the breeding industry worse. How to raise chickens in autumn and winter is a common concern for the breeding industry. In view of this, Xinde sums up the experiences of domestic experts and puts forward the plan of raising chickens in autumn and winter in combination with the status of chickens, providing the farmers with a method for raising chickens in autumn and winter. To help the flock safely through the autumn and winter, increase the efficiency of autumn and winter chickens.
The main contents of the letter's healthy chicken raising plan in autumn and winter include:
Scientific brooding Healthy and good chickens are the basis for determining the success or failure of chickens. The signs of healthy chicks are chick spirits, crisp sounds, no dehydration of chicken feet, no diarrhea, Newcastle disease, transmission, bursa, rein Orphan, flu and other maternal antibodies are high and tidy, and there are no egg-borne diseases such as diarrhea and mycoplasma. Poor quality chicks have a high rate of early scouring, Escherichia coli and mycoplasma prone to develop in the middle of the breeding period, and it is even more difficult to prevent viral diseases in the rearing period. Unhealthy chicks result in uneven chicken size, poor growth, indigestion, and long-term diarrhea. Unhealthy chicks can cause increased feed consumption, high feed-to-meat ratio, and slow growth. Poor quality chicks increase farmers' raising costs and breeding risks. The quality of chicks is the basis and early brood management is the key.
The key part of the brooding period is to bring the room temperature to the required temperature 48 hours before the chicken is pre-heated in advance to provide a comfortable environment for the chicken. After entering the chicken, the temperature should not go up or down, and the temperature difference should be controlled within 3°C.
See the young Shiwen When the normal temperature is appropriate, the chicks are arranged in a starry manner in the house. About 5% of the chickens in the flock are breathing. When the temperature is high, they are scattered in the wall roots. Most of them open their mouths to breathe. When the temperature is low, the chickens gather around the stove.
The humidity in the brooding house is generally maintained at 70% of the humidity in the first 10 days (measured by a hygrometer), and it is advisable for the person to enter the house to feel dampness on his face. The method of humidification generally evaporates vinegar on the stove or sprays the disinfectant in the house. Avoid high temperature and high humidity or high temperature and low humidity phenomenon. High humidity will cause large ammonia and hydrogen sulfide odor in the house, impaired chicken respiratory mucosa, lack of oxygen, chickens susceptible to pneumonia, ascites and diarrhea; low humidity chicken dehydration Poor absorption of yolk, feather dry, dry claws, prone to cold, dehydrated chicken within 1 week will never be a qualified broiler, humidification should start before entering the chicken (or even disinfection).
After entering the house, the drinking chicks need to drink water immediately. Use clean cool boiled water to add 5% glucose and 0.05% Navitas. Do not drink to teach people to prevent dehydration.
Feeding drinking water and opening food at the same time, the first week of feeding adhere to the principle of feeding less frequently, feeding once every 3 hours, before each feeding, the trays should be cleaned and washed, after 48 hours of feeding, The proportion of chickens filled with sac is to reach 95%, and unqualified ones are eliminated. In the first week, the appetite of chickens is mainly bred, and the more you eat, the better, and the development of gastrointestinal function, which will facilitate the growth and disease resistance in the future.
The early elimination of the chicks found that the chickens with poor mental state, no food, and anal paste were singled out and eliminated, and they must be eliminated. Because the chickens were raised rather than the sick chickens, the chickens with the problems were sooner or later Elimination, weak chicks to eat the material and the final illness of the drug also infected the entire flock, late Amoy is not as good as early Amoy.
High-quality brooding drugs The principle of selecting brood-brooding drugs is small side effects, broad-spectrum antibacterial, convenient feeding, and high susceptibility. You can use Yang Lactofloxacin or Yang milk nano-milk for brooding. It can not only inhibit mycoplasma, white peony, and E. coli. Disease, but also has the effect of promoting growth and improving disease resistance.
Scientific feeding and management of cold and warm, moderate ventilation in autumn and winter climate is cold and changeable, large temperature difference between day and night, can take appropriate increase in breeding density, close the doors and windows, drinking warm water and hot stove heating methods such as cold insulation, the rear of the culture to maintain the minimum temperature Between 18 °C ~ 20 °C.
In autumn and winter, the temperature is relatively low, the doors and windows of the chicken house are closed and the ventilation is reduced. However, harmful gases such as ammonia gas, carbon dioxide and hydrogen sulfide produced by chicken exhaust gas and chicken manure still exist, and it is easy to induce chicken respiratory diseases. Therefore, we must effectively handle the relationship between ventilation and warmth, timely removal of feces and debris in the house. When the air in the house is more dirty, it is necessary to increase the ventilation volume and adopt the ventilation of the fan. Attention should be paid to the control and exchange time. If the chicken is found to be disease-free and breathless, the house is full of dust and smells. This indicates that the air in the house is extremely dirty and should be immediately ventilated. Natural ventilation should prevent the thieves from being exposed to cold stress.
Reducing humidity and maintaining relative humidity In autumn and winter, the ventilation in the chicken house is small and the evaporation of water is reduced. In addition, the hot air in the house is exposed to the cold roof and the wall will condense into a lot of water droplets, causing excessive moisture in the house, giving bacteria and The large number of parasites creates the conditions. Therefore, we must strengthen management, pay attention to keep the chicken house clean and dry, timely repair of damaged sinks, avoid over-filling with too much water, and strictly forbidden to splash water on the floor.
The relative humidity is preferably 60% to 70%. Higher humidity is conducive to the survival and reproduction of microorganisms. If accompanied by temperature, it will increase the hazard. When the humidity is low, the chicken house is dry and it is easy to induce chicken respiratory diseases. Especially when the chicks are in a dry environment for a long time, they can cause dehydration and debilitation. Therefore, attention should be paid to the adjustment of the humidity in the house. Winter litter for ground chickens is relatively dry and should be often sprayed or spray-sterilized.
Regular disinfection and disinfection work should be carried out throughout the entire process of raising chickens. In autumn and winter, the temperature is low and the rate of bacterial growth slows down. However, in autumn and winter, the climate is cold and the resistance of chickens is generally weakened. Disregarding disinfection can easily lead to outbreaks of disease. Can choose to disinfectant, real gold iodine, Wei Dian, bacteria poisoning and other disinfectants disinfectants inside and outside the rotation.
Increase energy, enhance the health of chickens by feed to obtain heat to maintain body temperature, the lower the outside temperature, the more heat the chicken uses to protect the cold. It has been determined that winter chickens consume 10% more food than other seasons. Therefore, in the winter chicken feed must ensure that the energy is sufficient, in addition to ensuring a certain percentage of protein, should be appropriate to increase the high energy feed containing starch and sugar, in order to meet the chicken's physiology and production needs.
The resistance of chickens in winter is declining. Special attention must be paid to epidemic prevention and regular vaccination should be conducted. According to the actual situation can also be regularly fed some preventive drugs, appropriate to increase the content of vitamins and trace elements in feed. In autumn and winter, chickens can be used from the brooding to increase the intake of vitamins and improve the disease resistance of chicks. When the weather changes, transfer, refueling, vaccines and other stress occur, the new generation of Navitas can be used in time to eliminate the stress and improve The resistance of chickens; Pu Li Jian is often added to drinking water, it has the ability to prevent germs, resist oxidation, inhibit mold, detoxify, improve immunity, reduce feed ratio, and improve production performance. The household's approval has been included in many health care programs.
