In summer, the temperature is relatively high. For the chicken cage chicken users, it is necessary to do a good job of cooling the chicken house. Chicken battery cages have high density of chickens, and high temperatures tend to cause heat stress in chickens. Heat stress can affect the growth and production performance of egg broilers. Therefore, while the farmers are doing a good job of cooling down the summer house, they should also pay attention to prevent the phenomenon of heat stress in the chickens.

The main points of prevention and control of heat stress are:

1. Improve the environment of the house: heat stress is mainly caused by high temperature. Therefore, the main measure for farmers to control heat stress is to cool and ventilate the house. Farmers should strengthen the ventilation work for the house in time and keep it. A reasonable egg cage feeding density, you can install wet curtain equipment for the cooling of the chicken house, with ventilation equipment, the efficiency is better, can significantly reduce the temperature of the house about 10 °C.
 
2. Timely adjustment of feed formula: high temperature weather will affect the feed intake of chickens, and the reduction of feed intake of chickens will not meet the needs of nutrients in the body, so farmers should adjust their feeding in the summer. Increase the amount of energy and protein added to the feed, as well as add some vitamins and trace elements.

 
3. Change the feeding time: The average feeding time of the farmers is early, middle and late, but in summer the farmers can change the feeding time. Farmers should try not to feed the laying hens when they choose high temperature. They can choose to feed in the early morning and evening to prevent the increase of body temperature caused by eating, which will aggravate heat stress and increase the feed intake and increase accordingly. The body is resistant.

4. Adding heat-resistant stress substances: Many farmers know that vitamin C has the effect of reducing stress, so farmers can choose to add a large amount of vc (0.1-0.2g per kg of feed) to drinking water or feed. The body's ability to resist heat stress relieves the symptoms of heat stress; adding 0.2%-0.3% baking soda can reduce respiratory acidosis, improve the intestinal alkaline environment, increase the concentration of calcium ions in the blood, and increase the absorption of calcium. Improve the quality of eggshells and prevent egg yolks from licking. Some drugs with heatstroke resistance such as borneol, mint or their preparations may also be added as appropriate.

5. Supply sufficient cool drinking water: Continuously supply low-temperature well water as much as possible at high temperature. After drinking, the chicken can significantly reduce body temperature and prevent heat stress.

6. Individual treatment: In the usual feeding management of the farmers, the chickens should be observed in time, and the symptoms of heatstroke in individual chickens should be taken quickly.

Nowadays, many farmers have started to use fully automatic poultry equipment for sale to raise chickens. On the one hand, automatic feeding can be realized, on the other hand, it can also automatically remove manure, which simplifies the farming process of the farmers. What are the advantages of fully automatic chicken farming?

1. First use the cages in the automatic chicken raising equipment for broiler breeding, which saves the time for the farmers to catch chickens and catch chickens. The broilers can live on the cages from the beginning of the chickens until they enter the market.

2. Reduce the use of the chicken house area. When using the complete set of broiler chicken automatic equipment for breeding, the equipment has a small footprint, and the use of cages is relatively large, which can be said to be two birds with one stone.

3. Guarantee the food safety of broilers. When broilers grow up, they must enter the market and become food in the mouth of consumers. The use of breeding equipment for breeding can reduce the incidence of flock diseases, thus reducing the feeding amount of chickens and eliminating the The residue of the drug can provide the market with green and pollution-free chicken.

4. It is convenient for farmers to manage. The use of complete sets of equipment for breeding can be managed by column, which not only can improve the conversion rate of feed, but also help the farmers to observe the flocks and timely discover the weak chickens present in the flocks. Eliminated.

5. Environmental protection and safety, using complete sets of equipment for breeding, so that the feces produced by the chickens will not fall on the ground, farmers can use the protein in the feces as a feed for other animals for breeding. It is environmentally friendly and safe, and the septic machine equipment can clean up the manure of the chicken house in time to create a good living environment for the chickens.

Summer is a season with high temperature, most of the pathogens are killed, and the epidemic situation of the flocks is much less. However, due to the high temperature and high accidents of chickens in summer, the farmers must pay attention to prevention during daily feeding management. Let's take a look at the precautions for the summer chicken farm.
 
1. Pay attention to the temperature of the house
 
Chickens are resistant to freezing and heat and are very sensitive to high temperatures. If the temperature in the house continues to rise above 32 °C, the flock will have a heat stress reaction, open mouth breathing, half open wings, loss of appetite, or fall in the chicken cage, not willing to move. If the temperature of the house is above 35 °C, the chicken will have a fainting reaction and even cause a large area of chicken death.

Therefore, in the usual inspection of chicken farms, if large groups of chickens are found to breathe and drink more, especially physical fitness and obesity are more obvious. At this time, we must quickly think of ways to cool the chicken house, you can sprinkle water in the chicken house, it is best to spray down, or open the fan. For mentally degraded or fainting chickens, quickly transfer to a cool place, you can put blood on the cockscomb or wings, and add multi-dimensional in the chicken drinking water to speed up the recovery of the flock.

2. Pay attention to the number of dead chickens

It is normal for chickens, large or small, to die every day in large-scale chicken farms (mostly uncontrollable deaths of weak chickens). If you find that the number of dead chickens suddenly increases for several days, you should pay attention. It is recommended to collect the dead chickens, and to dissect more than one, to find out the reasons, and to take measures to prevent greater casualties.

3. Pay attention to the chicken line problem

In the summer, in order to cool the house, high-power appliances such as fans are used. With more electricity, the load pressure on the line is large. Because of the excessive load on the line or the aging of the line, the fires that cause the farm to suffer a devastating blow are everywhere. Our farmers have to pay special attention. In the summer, you must use electricity safely, check the circuit in time, replace the aging wires, and prohibit the burning of flammable and explosive materials in the chicken house.

The summer weather is hot, and the egg production rate will drop, especially after entering the sky, so the farmers need to manage the egg production rate in the summer. Strengthen the ventilation and ventilation of the chicken battery cages. In the summer, the ventilation can not only cool down, but also ensure the air is fresh. Evaporative cooling methods such as wet curtains, sprays, and roof sprays can be used. Evaporative cooling is a better cooling method at present, but it should be noted that when using a wet curtain to cool down, there should be an openable air inlet near the wet curtain. When the humidity exceeds 70%, the wet curtain should be closed and opened. Ventilation at the air inlet.

Many large-scale chicken farms have strict requirements for drinking water equipment for chickens. Water-line drinking equipment is usually used, which can take into account functions such as immunization and drug administration. But what if the chicken farm water line is dirty and blocked of poultry farming equipment? How should the waterline be cleaned up?

1. Control of water quality

The drinking water depth of the chicken farm should be more than 100 meters, which will be cleaner.

2. Choose cleaning disinfectant

Choose a cleaning and disinfecting agent that can effectively dissolve biofilm, mucus and scale in the water line. According to the disinfection effect of different disinfectants and the cost of use, choose the appropriate water line immersion disinfection.

3. Immersion cleaning water line and pipeline process during empty period

1) Open the water line and completely drain the water in the pipeline;

2) Add sodium dichloroisocyanurate powder to each water tank, add water to mix evenly, and close the valve of the straight water line;

3) Open the valve at both ends of the water line, release the clean water, open the water line to connect the valve of the water tank, press the last nipple at both ends of the water line to smell the chlorine smell, close the valve, soak and disinfect for 4 hours, which will kill the residual bacteria. And further remove residual biofilm;

4) After the immersion disinfection is completed, close the water tank outlet valve, open the water tank drain valve, drain the remaining disinfection solution, and open the water tank inlet valve, flush the water tank, and close the straight-through pressure regulating valve to open the straight-through Water line valve (not through the pressure regulating valve directly through the water line), then open the valve at both ends of the water line, release the disinfection solution, and then rinse the water line with 1~2 sponge balls;

5) The pipeline from the well to the chicken house should also be thoroughly cleaned and disinfected. It is best not to flush the pipeline inside the house with the water in the pipe. The pipe should be connected to the cannula of the dosing device and backflushed. Pipe outside the house;

6) The washing water should contain disinfectant, the concentration is the same as the concentration of drinking water in the feeding period of the chicken, and the disinfection of drinking water is sodium dichloroisocyanurate (the effective concentration of residual chlorine is 3~5ppm disinfecting water).

4. Feeding period soaking water line operation process (night operation)

1) Check whether the sewage connection pipe at both ends of the water line is normal and the water line connection is unblocked;

2) Add sodium dichloroisocyanurate powder (30% effective chlorine) (125g to 200kg water) or 6.5% chlorine dioxide (500g to 200kg water) to each water tank, add water and mix well, and close the straight water. Line valve

3) Turn off the light for 30 minutes or adjust the height of the waterline to a height that the chicken cannot reach;

4) Open the valve at both ends of the waterline, release the clean water, open the waterline to connect the valve of the water tank, press the last nipple at both ends of the waterline to smell the chlorine, close the valve, and immerse for 30 minutes;

5) Close the water outlet valve, open the water tank drain valve, drain the remaining disinfection solution, open the water inlet valve, flush the water tank, close the straight-through pressure regulating valve, and open the straight water line valve (not Pass the pressure regulating valve directly through the water line), then open the valve at both ends of the water line, release the disinfection solution, and then rinse it with 1~2 sponge balls;

6) After the water line of poultry equipment for sale is immersed and disinfected and rinsed, the inflowing water source must be fresh and chlorinated.

Strengthen feeding management and strict sanitation and disinfection measures

1. Provide adequate drinking water in a timely manner. The water content of eggs is about .73%, and the daily water consumption of chickens is 90-325 ml. The higher the egg production rate, the greater the water requirement. For every 10% increase in egg production rate, the daily drinking water per bird increases by 12 ml. The amount of water in summer is doubled in winter, about 2-3 times the amount of feed intake. Therefore, to ensure that the chicken drink clean cold water in a timely manner, the water temperature is about 10 degrees, it is advisable to enter the water pipe of the chicken house to be buried in the ground 90 cm. The best time to drink water should be selected at 6-10 in the morning, and the chickens have the most appetite. When the temperature exceeds 30 degrees, add the right amount of vitamin C per kilogram of drinking water plus 200 mg or 0.1% of baking soda. This will improve the cardiovascular metabolism of the chicken and enhance the body's ability to adapt to high temperatures.

2. Clear chicken manure in time and disinfect regularly. For disinfection of the chicken battery cages, ground, walls, sinks, troughs, etc. of the house, choose a disinfectant that is less corrosive and has a strong killing power against the pathogen. Keep the air fresh and reduce the content of harmful gases such as hydrogen sulfide and ammonia in the house.

3. Reduce various stress factors. Human factors such as transfer, transportation, and vaccination should be avoided as much as possible. When it is necessary, it should be chosen at night or in a cool time. In addition, laying hens must have a dark rest time of more than - hours, otherwise the breakage rate of the eggshell will increase. At the same time, add vitamin 1 in drinking water! The same amount as the previous 0.63% ammonium chloride can also alleviate the stress of the flock.

Change the feeding method and adjust the diet formula

1. Adopt two feeding methods. In the morning, it should be fed early, and the feeding time should be extended at night. When it is hot in the afternoon, it can be fed or green-green feed, such as chopped watermelon rind.

2. Appropriately improve the nutritional level of feed. For laying hens, the energy level of the diet can be reduced by about 10%, and the protein level is increased by 1% to 2%. 3% of bean cake or 2% of fishmeal can be added to the diet during specific operations. For broilers, the feed energy can be reduced by 10-15%, and the crude protein is increased by 1%-1.5%. In the specific operation, the cod liver oil can be sprinkled in the feed by 0.3-1 ml per chicken. Note that the summer feed is mildewed and should be ready for feeding. The storage time should not be too long.

3. Increase the content of various vitamins. When the weather is hot, the vitamin content should be increased. The general addition amount is about 2 times normal. In particular, pay attention to increase the content of vitamin 1, vitamin 2, vitamin 3 and vitamin e to promote the absorption of calcium and phosphorus in chickens.

4. Timely calcium supplementation. Most of the calcium absorbed in the morning is stored in the bones. The calcium absorbed in the afternoon or evening can be used for the formation of the eggshell at night. Therefore, the laying hen should be properly replenished at dusk, and the amount should be 2.3% of the diet.
