The symptoms that occur in laying hens during heat stress are:Respiratory rate increases, heart rate increases, and water intake increases.

When the ambient temperature exceeds32°CAt this time, chickens exhibit symptoms such as neck extension, mouth opening for breathing, wings spreading and drooping, increased water intake, decreased food intake, mental exhaustion, cyanosis of the comb, body temperature above 42.5 ° C, reduced egg weight, and an increase in soft shelled and cracked eggs in laying hens.

Plant grass and greenery around the chicken coop, plant plants for shade, plant climbing plants such as ivy for insulation, and cover the roof with grass curtains.

Closed chicken coops can be equipped with ceiling fans, blowers, air conditioners, or exhaust fans. The house should have skylights, and the north and south windows should be opened as much as possible.

In the daily high temperature stage, spray with low concentration disinfection water for 2-3 times, and can be used directly when the temperature is highSpray clean water on the chicken bodyGenerally, spraying once every 3 hours can reduce the room temperature by 4-5 ° C, and the effect is significant. But pay attention to opening windows for ventilation to prevent the humidity inside the building from increasing.

Egg laying hens are naturally timid. They need to turn on the lights, feed, drink water, and pick up eggs at regular times every day. The feeding staff should also be fixed and reduce the frequency of entering and leaving the chicken coop. They should try to maintain a quiet environment inside and outside the coop as much as possible.

In hot weather, the disease resistance of laying hens decreases, and artificial stress factors such as herd switching, transportation, and vaccination should be avoided as much as possible. When necessary, try to choose early, late, or when the weather is cool. Simultaneously adding anti stress drugs to feed and drinking water.

Before the arrival of high temperatures in summer, sick, disabled, weak chickens, low egg laying chickens, and obese chickens in the flock should be eliminated in advance.

Before the arrival of the high birth or peak period, chickens in the flock that do not meet the weight standards or have not yet started production should be eliminated in a timely manner to reduce the feeding density.

In seasons prone to heat stress, a balanced diet is recommended3-5 pieces per square meter is suitableCaged laying hens should be raised more frequently than usualDensity reduced by 20%The appropriate size for a group of laying hens is 150-200 per group.

The amount of water consumed by laying hens during high temperature weather is approximately equivalent to their feed intake3-5 timesThe higher the egg production rate, the greater the water demand. Therefore, water dispensers or sinks should be added to the chicken coop to ensure a continuous and sufficient supply of fresh and hygienic drinking water throughout the day.

Drinking water should also be kept cool,A water temperature of 10-13 ° C is recommended. During the dog days of summer from 10:00-17:00, change the water every 2-3 hours and clean and disinfect the drinking water utensils once a day.

After entering summer, the average feed intake of general chicken flocks decreases by 10% to 15%, and some chickens even reach more than 30%. Therefore, the feed formula should be adjusted reasonably.

Feed for laying hens during hot seasonsThe protein content should increase by 1-2 percentage points compared to other seasons, reaching over 18%. Therefore, it is necessary to increase the amount of soybean meal, cottonseed cake and other cake feed in the compound feed, with a dosage of not less than 20% to 25%. Add to the diet1.0%~1.5% vegetable oilOr add high-energy enzymes to increase energy, while adding heatstroke prevention and cooling drugs.

Adjust the feeding time and feed when the air is cooler in the morning and at night,Using granular materialsTo increase its feed intake and meet the production and physiological needs of chickens.

Drug prevention is an effective measure to reduce heat stress, and commonly used drugs includeChlorpromazine, reserpine, vitamin C, multivitamins, berberine, baking sodaFarmers can make reasonable choices based on their actual farming situation.

Chicken coop manure should be regularly cleaned, transported and stored for fermentation.

Disinfect the chicken coop once a week, adhere to cleaning and disinfection of the sink once a day, combined with spray cooling with chicken disinfection.

If some laying hens are found to have obvious heat stress symptoms, they should be immediately transferred to a cool and ventilated place, andNeedling and bloodletting on the comb and wings of the chickenAt the same time, feed the chicken1-2 drops of Ten Drops of Water, 4-5 pills of Human PillThis way, most chickens can recover quickly.
