What problems should be paid attention to in broiler breeding in high temperature season

How to raise broilers and improve efficiency? The experience and lessons of raising broilers are summarized as follows for the reference of broiler farmers.

First of all, efforts should be made to create perfect standardized feeding facilities. Let the chicken be put on the internet, clean and hygienic, and reduce the cost of medicine. The roof wall of the henhouse should have good thermal insulation performance to reduce the heating cost.

Second, breeding excellent new broiler varieties with strong disease resistance.

Third, breeders should be serious and responsible. Every step (chicken feeding, transportation, boiling water cooking, constant temperature heating, chicken catching and fire prevention) should be strict and meticulous, from temperature change to ventilation, from drug feeding to health and epidemic prevention, from chicken coop disinfection to chicken disinfection, efforts should be made to create an excellent growth environment to nip in the bud.

The fourth is to observe the growth of feces and chickens frequently. Solve the problem in time, find the cause quickly and timely, dissect and test, and prescribe the right medicine in time, otherwise it will delay the treatment, increase the cost of medicine and increase the mortality rate.

Fifth, adhere to the policy of "putting prevention first, combining prevention with treatment, and treating both the symptoms and root causes".

Sixth, store garlic, garlic sprouts, Jiang Miao, pepper stalks and other "three spicy" and Chinese herbal medicines such as Artemisia annua and Artemisia argyi as much as possible. These materials are dried and crushed as additives. These additives have low price, complete functions, disease prevention and health care. Each batch of chickens can be regularly fed for four courses (one course every two days), which can significantly improve the body resistance of chickens and prevent enteritis, colibacillosis, viral diseases and coccidiosis. According to reports, Guangrao County Broiler Company has been promoting the feeding of Chinese herbal medicine additives to produce green broilers, which is favored by Japanese customers.

Seventh, rational use of high technology.

1, the application of microecological preparation. It has been reported that Qingdao Jiulian Group has widely used microecological agents to improve the growth environment of broilers and produce natural chickens, so that the products of Jiulian Group can be exported to Japan, the Middle East and other countries unimpeded.

Microecological preparation is a beneficial microbial flora developed by biotechnology, which can maintain the microecological balance of intestinal tract of livestock and poultry, prevent and control yellow and white dysentery and coccidiosis, and promote the growth of livestock and poultry. Weight gain is remarkable, feed conversion rate is improved, immunity and disease resistance are enhanced, and the use of antibiotics can be reduced or replaced to produce green broilers. Among them, the most kinds of microorganisms are em flora, which is mainly used for disinfection of feed and drinking water.

First of all, EM is gradually mixed into the complete feed according to the proportion of 3-8%, and there is no interruption from chicken to slaughter.

Secondly, drinking water and feeding antibiotics are used alternately. 1-7 days old, 300 times the drinking water ratio, 8- 14 days old, 500 times the drinking water ratio, after 22 days old, 500 times the drinking water ratio.

Third, spray the hen house, utensils and workshops with EM200 times solution 3 hours before entering the chicken, so that beneficial bacteria can occupy the whole environment. During the feeding process, chickens should be disinfected 200 times every other day, including air and grass spray disinfection. It can not only eliminate the odor and ammonia smell, but also inhibit the reproduction of germs and molds, and also eliminate dust floating objects, thus reducing the incidence of respiratory diseases in chickens.

2. Use powerful nano-863 biological growth promoter. Powerful nano-863 does not need external energy when used, and is widely used in many growth stages of animals and plants. Nano-863 has magical effects because it contains nano-materials. When water, feed and seeds come into contact with it, it can continuously deliver special biological energy, greatly improve its activity, activate biological cells and tissues, promote the growth of animals and plants, improve immunity and enhance anti-stress ability. Scientists call it an "energy block". The appearance of powerful nano-863 has opened up a new road for high quality, high yield, high efficiency and low consumption of agriculture, animal husbandry and fishery, and has been welcomed by farmers. Its correct use method:

For drinking water treatment, strong nano-863 was soaked in a water storage container for a long time, with the perforated surface facing upward. The maximum treatment capacity of each nano-863 is 1.50kg, and the first treatment takes more than 5 hours, so attention should be paid to recycling when using it.

Feed processing: when processing bagged materials, insert the powerful nano-863 perforated face downwards into the surface layer, tie the bag mouth tightly, and then feed it after 8 hours. When dealing with bulk materials, first lay a plastic film on the ground, then pile 150 kg of materials into small piles, put nano-863 at the bottom of the materials, and treat 1 night before feeding. The longer the treatment time, the better the effect. Diluting drugs with water treated with nano-863 can significantly improve the curative effect. Verified by authoritative organizations and many chicken farm tests show that nano-863 is an essential instrument for chicken farmers.

Based on the above, we insist on prevention first, treat both the symptoms and root causes, and restore the health of chickens in time and quickly. In addition, the application of high technology has proved that it can greatly improve the feed conversion rate, save feed, reduce production cost, disinfect and deodorize, improve the environment and greatly reduce the incidence of chickens. 1 chicken saves nearly 1 yuan, saves about 0.5 kg of feed and gains 200 grams. Moreover, after using EM and nano-863, the chicken has good quality and no drug residue, so it is a green food.

Several good methods of raising broilers in winter

The purpose of broiler production is to obtain the maximum economic benefit and high quality products. However, due to the rapid growth of commercial broilers, the adaptability of broilers to the environment and the resistance to diseases are reduced, which is easily affected by many factors such as feed quality, resulting in lower feed reward, higher mortality and ultimately lower economic benefits. Therefore, it is very important to master the following aspects of broiler feeding management in winter.

1, the henhouse building has good thermal insulation performance and timely ventilation.

In winter, the climate is cold, and the indoor temperature is quite different from the outdoor temperature. It is the main problem to be solved in winter to ventilate and keep the indoor temperature. The henhouse requires good cold-proof performance to meet the requirements of heat preservation in winter. Strictly guard against the phenomenon that chicks die from low-temperature crowding and squeezing.

At the same time of ventilation, be careful not to cause the temperature in the house to rise and fall, to prevent the stress reaction caused by excessive temperature difference from causing diseases, and the vent should be higher than1.5m above the chicken's back. When the temperature drops sharply and the cold-proof and heat-preservation work can't keep up, it is often easy for broilers to suffer from exogenous cold, and respiratory diseases characterized by cough, sneezing, tracheal rales and dyspnea appear. Therefore, breeders should master climate change and do a good job of cold protection and warmth. Henhouses should be well maintained to prevent thieves and circulation from invading chickens. Broilers raised on the flat ground should be padded to raise the indoor temperature. Change the padding frequently and open the window for ventilation at noon. Generally, ventilation begins at the age of 6 days, and gradually increases after the age of 6 days, so that chickens have enough oxygen. The temperature in the house is controlled at 34.5℃-35℃ 3 days before the chicks enter the house. After the chickens enter the house, raise the temperature to 1℃-2℃, and the temperature within 1 week is preferably 35℃-36℃. At this time, the chickens are in good condition, lively, evenly distributed, freely moving and eating normally. At the same time, we should pay attention to the changes of chickens and adjust the temperature in time. If the chickens get together, they will "squeak" and shrink their heads, indicating that the temperature is too low and the temperature in the room should be raised. If you are breathless and drink water frequently. It means that the temperature is too high and the indoor temperature should be lowered. The temperature drops to 30℃-32℃ at the age of 2 weeks, to 26℃-28℃ at the age of 3 weeks, 1 week and then to a constant temperature of 23℃.

2, to prevent the accumulation of ammonia

In winter, the climate is cold, so ventilation can't be neglected to keep the chicken house warm. The feces and wet padding discharged by chickens can't be removed in time, which leads to ammonia accumulation and concentration increase in the chicken house, leading to ammonia poisoning or other diseases in broilers. Ammonia has a strong stimulating effect on the respiratory mucosa and cornea of chickens, which usually causes the following hazards to broilers: listlessness, loss of appetite, sticky oral liquid, increased desire for drinking water, dyspnea, cough, runny nose, tears, and severe corneal redness until death. Due to the accumulation of ammonia gas in the house, the relative lack of oxygen and the cold weather, the metabolic rate of chickens increases, which is easy to cause ascites syndrome in fast-growing broilers. In order to prevent the adverse effects of ammonia on broilers, it is suggested that chicken farms and flocks should do the following feeding management work: (1) The padding should have a certain thickness, generally more than 5 cm; Sprinkle water as little as possible during the operation to prevent the water tank from leaking and wetting the padding; If the humidity in the henhouse is too high, the feces and wet padding in the henhouse should be removed in time. In addition, ammonia absorption deodorant can be used to reduce the ammonia concentration in chicken coops, such as ferrous sulfate, calcium superphosphate, copper sulfate and hydrated lime.

3, reasonable feeding, to prevent the spread of disease.

According to the different growth stages of broilers, the diets were prepared according to feeding standard. Because of the low temperature in winter, broilers consume a lot of calories. When preparing diet, the standard of metabolic energy in feed can be raised appropriately, and the proportion of protein in feed can be reduced appropriately. At the same time, special attention should be paid to the vitamin content in the diet to meet their needs. Feed should be mixed now to prevent freezing. When conditions permit, it can be fed with hot materials and warm water. The raw grain of feed must be free from mildew and impurities to prevent respiratory diseases.

Do a good job in the prevention of viral and bacterial diseases. When broilers are weak and their resistance drops, some diseases may also be complicated with respiratory diseases. Therefore, while improving the body's resistance, we should do a good job in the prevention and treatment of diseases. Vaccination should be carried out in strict accordance with immunization procedures. You should always use some drugs to prevent diseases. Disinfect chicken coops regularly. It is best to fumigate empty henhouses with formalin and spray efficient and non-toxic disinfectants when feeding. Disinfect chickens regularly, generally using spray disinfection and drinking water disinfection. After the broiler has respiratory diseases, it is necessary to find a veterinary diagnosis in time and prescribe the right medicine. Symptomatic treatment can use some antiasthmatic and antitussive drugs appropriately, which can reduce the number of people who die of dyspnea. The principle of prevention and control should take comprehensive measures: establish a strict health and epidemic prevention system, do a good job in environmental sanitation, strictly control foreigners and vehicles entering the production site, and formulate a scientific and effective disinfection system; Strengthen the monitoring and purification of breeder chickens; Drug control; Immune. In winter, the contradiction between ventilation and heat preservation should be solved, indoor air quality should be maintained, sanitary management should be strengthened, and drugs should be used rationally, so that the incidence rate will be greatly reduced, the growth and production of broilers can be guaranteed, and ideal economic benefits can be obtained.

4. Strengthen feeding management.

Before entering the huts, the huts should be strictly cleaned, disinfected and fumigated. Thoroughly clean utensils, clothes and hats, houses, etc. Because of the physiological characteristics of broilers, drinking water before eating after entering the house, especially for chickens transported for a long distance, can replenish the water lost from the body in time. For chickens unwilling to move, artificial feeding measures should be taken, but attention should be paid to light movements to avoid crushing. The lighting time should be shortened rather than extended, and the position, time and intensity of the light source should not be changed at will to make the indoor lighting uniform.

The ground should be dry, and the cement ground is easy to get wet because it does not absorb water. It is best to hit the ground with concrete, so that the ground is breathable and kept dry and not wet.

Choose a good cushion material, fresh, dry, soft, moldy and good in water absorption, preferably shavings. Use it skillfully when using it. It's best to spread the mat at one time, don't add it sporadically, and turn it frequently to make it neither hard nor soft.

Control drinking water to meet the demand for water. Generally, the amount of drinking water is 2-3 times that of material consumption, but don't supply too much water, because too much water will aggravate the humidity of bedding. Don't wash vegetables or store water indoors to prevent bedding from absorbing water and prevent water loss when using water pipes.

Don't use too much salt in the chicken's diet to prevent drinking too much water, which will lead to high water content in chicken manure and wet straw mats or diarrhea. In addition, the fat content in the feed should not be too high, otherwise the feces will stick on the padding and harden easily, and the chickens lying on it will easily cause chest inflammation and cysts. Protein should be added to the diet in an appropriate amount, which is not easy to digest. For example, feeding bean cakes is easy to have loose bowels, and wet mats are harmful.

To solve the outstanding problem of chicken breast cyst formation, such as cage culture or net culture, a layer of soft adhesive tape can be added to the bottom of the cage or net to prevent the chicken's chest from directly contacting sharp iron wires and avoid chicken breast cyst. As long as the flat chicken is covered with soft grass instead of hard pad or hardened material, it can also prevent the occurrence of intestinal diseases in chickens

Broilers raised online are prone to non-communicable respiratory diseases, especially broilers aged about 25 days in winter. The pathogen of this disease is not bacteria or viruses, nor parasites, but the result of poor feeding and management. Generally speaking, from the first day, it is dried continuously or intermittently, and there is too much dust. Under the condition of poor ventilation, it is inhaled by chickens and accumulated for a long time. The prevention and control measures are to increase ventilation and ensure the oxygen content in the house on the premise of keeping the temperature in the house, which is the basic condition for chickens to get well as soon as possible without getting sick or getting sick. To maintain a certain humidity in the shed, the humidity should be around 20% in 1 week and around 60% in the second week. Broilers over 3 weeks old should be mainly ventilated, and the indoor temperature should not be lower than 265438 0℃. Try to reduce unnecessary stress factors and take all feasible measures to make chickens eat, so as to ensure the energy needs of the body and enhance the disease resistance of chickens. In addition to the above corresponding measures, appropriate antibacterial drugs and vitamins or baking soda should be added to drinking water and feed to enhance the anti-stress ability of chickens and alleviate acidosis caused by poor breathing.

5. Hygienic management of chicken farms

First of all, chickens should be introduced from healthy farms to prevent pathogens from being brought in through vertical transmission. Secondly, it is necessary to create a good feeding environment, including the chicken farm environment and the small environment in the house. General environment refers to the location as far away from other chicken farms as possible, with open terrain, convenient transportation and no external interference such as noise. Indoor environment refers to good thermal insulation and ventilation conditions, equipped with independent storage room, disinfection pool, dressing room, tool room, etc. Feeding utensils should be strictly distinguished from disinfection utensils, and disinfected regularly to prevent diseases in horizontal transmission. At the same time, we should regularly monitor the occurrence of diseases in nearby chicken farms and local areas, and take preventive measures. Regularly monitor the health status of the chickens in this field and deal with the epidemic situation in time. Third, adhere to the principles of disinfecting chickens, eliminating rodents, preventing rodents from spreading diseases, burning and burying dead chickens, and isolating sick chickens from healthy chickens.

In a word, the feeding and management of broilers in winter is a comprehensive work. In addition to the above points, there are many factors, such as chicken immunity, broken beak, feed quality, breeder management and so on. Therefore, only by grasping the key points of all aspects and considering comprehensively can the economic benefits of raising broilers in winter be improved.

How to feed broilers in summer

In chicken production, environmental temperature is one of the important factors affecting the performance of broilers. When broilers reach the age of 28 days, the most suitable production temperature is 265438 0℃, and the temperature in the chicken house often exceeds 30℃ in summer, which is very unfavorable for broiler feeding. Because it is difficult to raise broilers this season, summer is called the "anti-season" of broiler breeding, that is, the season that is not smooth. The influence of high temperature on broilers is mainly manifested in the following four aspects: (1) The feed intake is obviously decreased, and the growth rate is slowed down; (2) The breathing frequency is accelerated and the water consumption is increased. When the greenhouse temperature reaches 35℃, it can lead to heatstroke death of broilers; (3) With the decrease of growth rate, the feeding period of broilers is prolonged, and the nutritional demand for maintaining their growth is increased, which will eventually reduce the feed reward of broilers; (4) Due to the increase of drinking water, the moisture in chicken excrement also increases, and the padding is wet. It is easy to cause coccidiosis.

Therefore, the harm of high temperature to broilers is serious. In summer, reasonable measures must be taken to strengthen feeding management, reduce the negative impact of high temperature on broilers as effectively as possible, and keep broiler production at a high level. The technical points of raising broilers during high temperature in summer are introduced as follows for reference.

1 Strengthen ventilation and heat dissipation to reduce indoor temperature.

The power of the exhaust fan can be increased. For example, multiple 9FJ- 1.2 8m3/s fans can be used to increase the wind speed flowing through the chicken body, take the heat generated by take the chicken body in time, and accelerate the heat discharge in the house. Practice has proved that increasing human ventilation before morning is the most obvious effect, which can not only make broilers eat for a long time and endure the high temperature during the day, but also help to reduce the maximum temperature in the henhouse one day.

2 install wet curtain to cool down

Conditional can install wet curtain cooling device. The comparative data show that the average difference between wet curtain cooling and outdoor temperature is 5.8℃, and the average difference between wet curtain cooling and room without wet curtain is 3.4℃. m

3 Let the broilers drink cold water.

The temperature of deep well water is generally around 65438 08℃, which is a good refreshing drink for broilers and can effectively reduce the stress caused by heat. Because the amount of water consumed by broilers increases at high temperature, the amount of feces excreted is also large, which can take away more heat in broilers. Therefore, where conditions permit, a self-flowing sink can be used to continuously supply water with a small pump to keep the drinking water low. If the traditional vacuum water dispenser is used, the number of water changes should be increased, and the water added by the water dispenser should be the deep well water that has just been pumped.

4. Heat insulation, sunshade and sprinkling chicken on the roof.

The roof is the largest part of the heating surface of the henhouse, and wheat straw or straw can be used as the roof. If the roof is made of other materials (such as asbestos tile and cement board), it can be covered with grass curtains or planted with vines for shading, which can reduce the temperature of the henhouse to some extent. Spraying cold water on the roof with automatic sprinkler can reduce the indoor temperature.

5 Strengthen feeding when the weather is cool

When the weather is cool, broilers will increase their intake. Therefore, when the temperature drops and the weather is cool, we should pay attention to feeding in time, don't miss the feeding opportunity and increase the feed intake of broilers as much as possible.

6. Adjust the feed formula

When heat stress has a great influence on the feed intake of broilers, a high-energy and high-protein diet should be adopted. If fat is added to the diet to increase the energy concentration, the resistance of broilers to heat stress can be increased. Another example is that adding major amino acids (lysine and methionine) can reduce the body weight gain of heat-stressed broilers and improve the feed utilization rate.

7 Appropriate vitamin C supplementation

Generally, chickens will synthesize vitamin C to meet their growth needs, so they are not short of vitamin C. However, under heat stress, their ability to synthesize vitamin C will be greatly reduced, which cannot meet their own needs. Vitamin C can reduce the temperature and alleviate the adverse effects of heat stress on chicken metabolism. Therefore, vitamin C should be added to broiler diets in summer, and vitamin C powder ≥40% 50g can be added to 100 kg feed or ≥40% 25g can be added to 100 kg drinking water.

8. Prevention and treatment of coccidiosis and chicken diseases

In summer, the high humidity and high temperature of bedding are suitable conditions for the development of coccidiosis, which is easy to lead to the outbreak of coccidiosis. Farmers should always add anti-coccidiosis drugs (such as Qiuliling, Qiubiqing and Qiujing) to their feed in turn. When diarrhea occurs in chickens, anticoccidial drugs and hemostatic vitamin K3 should be used in combination, and the treatment effect is better.
